Power Packed: New Trends in Diesel Engines

Technology - often driven by emissions regulations - is always advancing in the diesel engine sector. The many companies producing engines for industrial use put plenty of time and energy into research and development to improve their products and save their customers money. Through 2017, we have seen a wide number of updates and new launches, many to coordinate with the upcoming Stage V regulations in Europe.

From new engines on the upper end of the power range, such as those introduced by Perkins and John Deere, to broad updates with new emissions technology, like the new line of Deutz products, to engines that are moving companies like Kubota into entirely new power ranges, 2017 has thus far been a strong year for the development of the diesel engine. 

John Deere launches new 13.6L engine
CONEXPO was the launching point for John Deere's next generation of engines, with the debut of the company's 13.6L engine for both their own machines and OEM applications.

Deere has equipped the new engine with an integrated high-pressure common-rail fuel system, reducing fuel consumption significantly at rated speed. Diesel exhaust fluid consumption has been reduced through design enhancements that improved the combustion process. In addition, designers have made the engine more compact and reduced its size and weight compared to other engines in the power range.

"Our engineers developed the new 13.6L engine to meet the power and packaging needs for a wide array of heavy-duty applications," said John Piasecki, director of marketing, sales and customer support for John Deere Power Systems. "The 13.6L engine demonstrates our ongoing commitment to recognizing and exceeding our customers' expectations. John Deere dedicated extensive internal resources to the clean sheet design of this engine to provide our customers with a power solution that surpasses standards in reliability and durability."

The 13.6L engine offers a maximum variable speed power rating over 500 kW (684 hp) and employs the same proven technologies as other engines in the John Deere lineup, particularly full-authority electronic controls, cooled exhaust gas recirculation (EGR) and a high-pressure common-rail fuel system. Single- and dual-turbocharger configurations offer OEM customers improved packaging and greater application flexibility. "These technologies are the key to our ability to meet emission requirements and still live up to our customers' power and packaging expectations," said Piasecki.

DD8 medium-duty joins Detroit Diesel lineup
"Daimler Trucks North America is excited to add the Detroit DD8 engine to its Medium-Duty engine lineup," said Kary Schaefer, General Manager, Marketing and Strategy for the company, adding that the engine "is ideally suited for the vocational applications across the Daimler Trucks North America family of products."

With a horsepower range of 260-350 hp and torque running from 660-1,050 lb.-ft., the DD8 expands on a medium-duty platform introduced in 2016 with the DD5. The goal is to provide customers with fuel efficiency and long maintenance intervals. In addition, the engine is launching with both engine and transmission PTO options to facilitate many vocational options. The DD8 will initially be available in the Freightliner M2106, 108SD and 114SD models.

"The medium-duty engine options are all about giving our customers added value when making their engine selections," Schaefer said. "The DD5, and now the DD8, will lead the industry in uptime and fuel efficiency. With these advantages as well as Virtual Technician, we are providing our customers a smart business solution."

Vehicles equipped with the DD8 will feature Detroit Connect Virtual Technician remote diagnostic service. Virtual Technician helps fleets make informed maintenance decisions, so that they only service their vehicles when needed.

Deutz plans for the future with engine launches
For Deutz, CONEXPO was an opportunity to display its expanded portfolio of engines, which now have a range from 2.2 to 18 litres. Notably, Deutz introduced a pair of four-cylinder diesels, the TCD 5.0 and TCD 9.0.

The TCD 5.0 will be introduced worldwide in 2019 to meet the next EU Stage V emissions standard. The engine will also comply with U.S. Tier 4 Final. This particularly compact, turbocharged and charge-air-cooled, 5L diesel engine generates 135-200 hp (100-150 kW) and 890 Nm of torque. The engine also conforms to the downsizing principle by producing more power from a smaller cubic capacity, enabling customers to replace larger displacement engines with more fuel-efficient and compact four-cylinder engines. The TCD 5.0 is a brand-new design with minimum pipework and fewer components for less complexity and maintenance. The new TCD 9.0 9L engine generates 300-400 hp (200-300 kW) and 1,700 Nm of torque. Its highly compact design makes it easy to install in a wide variety of applications, particularly excavators and wheel loaders.

The company is also introducing two six-cylinder engines, the TCD12.0 and 13.5, generating up to 400 kW (536 hp) and 2,500 Nm and up to 450 kW (600 hp) and 2,800 Nm, respectively. These engines, along with the TCD 9.0 and the future TCD 18.0, are the product of a collaborative partnership with the Liebherr Group.

Cummins award-winning X15 Efficiency Series
The Truck Writers of North America have recognized the Cummins X15 Efficiency Series diesel with their 2016 Technical Achievement Award. Presented in March, the engine was selected by a panel of industry journalists from Canada and the U.S. for its advanced combustion design.

"Cummins is honoured to receive the Technical Achievement Award for our 2017 X15 Efficiency Series, and it is especially relevant to us that this recognition comes from truck industry writers, many of whom have experienced the enhanced driveability and responsive performance of the X15 engine first hand," said Tim Proctor, Cummins X15 engine system technical leader.

He added that the 14.9L diesel gains three percent in fuel efficiency over the preceding model, the ISX15, through improvements to air-handling, combustion efficiency, reduced parasitic losses and advanced electronics, while maintenance should cost 40 percent less than previous engines over five years. 

Cummins redesigned its ISX15 to meet 2017 federal greenhouse gas and fuel economy requirements, and introduced two models called X15 Performance and X15 Efficiency. The Efficiency version employs an Atkinson Cycle in its valve action that adds fuel efficiency important to fleet managers.

Higher horsepower engines unveiled by Kubota
For Kubota - well known for its smaller engines under 100 hp - the aim with their new engines was to go bigger while adding new options for customers.

The new 5L V5009 is the first engine in what will be the new 09 series, with mass production scheduled to begin in 2020 to match up with EU Stage V emissions. The first engine above 200 hp produced by Kubota, the V5009 is compact but generates 210.9 hp (157.3 KW) and has aftertreatment including DPF and SCR. A four-cylinder engine, the new unit produces power previously only achievable with six cylinders. It also offers good fuel efficiency and output performance.

To achieve this high output combined with low fuel consumption, Kubota has made use of high-pressure supercharging, then used combustion matching to create high in-cylinder pressure. They also designed a ladder frame structure to ensure engine durability, improved the water cooling channel, and added a side power take off option and three ports for accessories, such as hydraulic pumps, for ease of use.

"Before they developed the V5009, our customers with larger application needs had to turn to another manufacturer. We received several requests for larger, more powerful engines, and are pleased to now be able to further position Kubota as ‘one source,'" said Kevin Keyes, vice president of sales and marketing for Kubota Engine America. "The V5009 will not require any major modifications to our customers' current machines because it is compact enough for easy installation. It should also significantly reduce running and operating costs, saving time, money and energy for our end users."

Volvo Penta looks forward
The off-road engine market has expanded in North America and abroad through recent years, thanks to upturns in most business segments. Volvo Penta is taking advantage of that with its current and near-future engine offerings.

"The success of our Tier 4 Final engines has led to increasing customer demand and consequently growth for us in the North American market," said Ron Huibers, president of Volvo Penta of the Americas. "As a premium engine manufacturer, we approach development of products with customer requirements at the heart of our operations. It's particularly great to see how the North American market for off-road diesel engines has increased since the last CONEXPO show of 2014, and we expect this momentum to continue in the future."

Volvo Penta's CONEXPO displays focused on engines ranging from 5 to 16 litres. The D5 series of 5L engines are equipped with a common-rail fuel system and, according to the company, are some of the most powerful four-cylinder diesel engines available. They are offered in a range from 143 to 218 hp, meaning they perform on par with larger six-cylinder engines and offer exceptional torque at low rpm.

New three-cylinder engines from Hatz
Hatz, the manufacturer of the established 4H50 engines, is introducing three-cylinder models targeted at compact applications. The new three-cylinders aim to be an ideal solution for the compact machine class up to 50 hp. The goal is not only to house engines in a compact installation space, but also to ensure the form and operation of the machine remains unchanged. If exhaust emission aftertreatment becomes necessary, the smaller size and reduced raw emissions of the smaller engines are a benefit.

The Hatz 3H50, at 1.5L and up to 2,800 rpm, will replace the 2.5L engines in the future. Torque and response behavior are considerably superior to the present generation. At the same time, fuel consumption is significantly reduced. The lightweight Hatz 3H50TI doesn't need any exhaust emission aftertreatment; nevertheless, the engine achieves compliance with Stage IIIA and Tier 4 interim standards in the power range from 25 to 50 hp. With a maximum torque of 146 lb.-ft. (at 1,600 to 2,200 rpm) and up to 62 hp, the Hatz 3H50TI is the top performer of the Hatz three-cylinders. Options are available that add EGR and DOC to the engines, and there is a version with DPF if required.

MTU showcases Stage V solutions
Rolls-Royce brought its MTU engine brand to CONEXPO and showed a range of engines as well as its Stage V approach for several of its products.
 
The MTU booth featured a range of engines spanning the 75 to 3,000 kW power range. At the booth were the Series 60 (224-496 kW), Series 900 (75-245 kW), Series 1000 (100-260 kW), Series 1300 (320-390 kW) and Series 1500 (400-460 kW), as well as higher power offerings including the Series 1600 (567-730 kW) and Series 4000 (800-3,000 kW). These engines are specially developed for off-highway applications in the construction, industrial, mining and agricultural sectors. In addition to engines, MTU also showcased its Stage V SCR aftertreatment solution for the MTU Series 1000, 1100, 1300 and 1500 engines.

MAN Engines increases Americas commitment
Building on a strong foundation based in years of North American presence, Germany's MAN Engines used CONEXPO to expand its visibility and affirm its commitment to the North American market. 

MAN Engines provides the technology and products for new partnerships in the field of construction and mining vehicles. MAN Engines covers a power range from 294 to 816 kW (400 to 1,110 hp) with the three engine series D2676, D3876 and D2862 with 12.4-, 15.2- and 24.2L capacities. The engine dynamics are adjusted to match the particular application using wastegate turbocharging or variable turbine geometry. In this way, MAN diesel engines provide sufficient charging pressure and dynamics for wheel loaders, excavators, dump trucks, and mobile cranes, even at low revs in the efficient engine speed range.

New platforms for Perkins range
Construction equipment manufacturers will have new options thanks to the addition of four new product platforms by Perkins. The company is adding engines in the 9-18L range, with a power offering of up to 800 hp.

"Our four new engine platforms are specifically designed to meet our customers' strategic and commercial requirements," said Andy Zuckerman, Americas Sales and Distribution Director. "We've developed a modular engine architecture which delivers the right performance, while enabling customers to develop single machine designs adaptable to multiple emissions standards."

The addition of a 9L 1700 Series, a 13L 2200 Series, a 15L 2500 Series and an 18L 2800 Series more than doubles the power range previously offered by Perkins, extending it from 8.2 to 597 kW (11 to 800 hp). From the compact 0.5L to the powerful 18L engines, equipment manufacturers can take advantage of Perkins' comprehensive engine range, saving themselves time and money by using just one supplier for all their engine needs, across their global machine lineup.

One example is the 9.3L 1700 Series, a six-cylinder turbocharged and aftercooled unit with direct injection and a fully electronic control system that will meet EU Stage V, U.S. EPA Tier 4 Final emission standards. With a power range of 250-340 kW (335-456 hp), it provides a strong option for construction applications, and has been validated to deliver optimal performance in the harshest working environments. 

Technology - often driven by emissions regulations - is always advancing in the diesel engine sector. The many companies producing engines for industrial use put plenty of time and energy into research and development to improve their products and save their customers money.

For Kubota - well known for its smaller engines under 100 hp - the aim with their new engines was to go bigger while adding new options for customers.

The new 5L V5009 is the first engine in what will be the new 09 series, with mass production scheduled to begin in 2020 to match up with EU Stage V emissions. The first engine above 200 hp produced by Kubota, the V5009 is compact but generates 210.9 hp (157.3 KW) and has aftertreatment including DPF and SCR. A four-cylinder engine, the new unit produces power previously only achievable with six cylinders. It also offers good fuel efficiency and output performance.

To achieve this high output combined with low fuel consumption, Kubota has made use of high-pressure supercharging, then used combustion matching to create high in-cylinder pressure. They also designed a ladder frame structure to ensure engine durability, improved the water cooling channel, and added a side power take off option and three ports for accessories, such as hydraulic pumps, for ease of use.

"Before they developed the V5009, our customers with larger application needs had to turn to another manufacturer. We received several requests for larger, more powerful engines, and are pleased to now be able to further position Kubota as ‘one source,'" said Kevin Keyes, vice president of sales and marketing for Kubota Engine America. "The V5009 will not require any major modifications to our customers' current machines because it is compact enough for easy installation. It should also significantly reduce running and operating costs, saving time, money and energy for our end users."

Volvo Penta looks forward
The off-road engine market has expanded in North America and abroad through recent years, thanks to upturns in most business segments. Volvo Penta is taking advantage of that with its current and near-future engine offerings.

"The success of our Tier 4 Final engines has led to increasing customer demand and consequently growth for us in the North American market," said Ron Huibers, president of Volvo Penta of the Americas. "As a premium engine manufacturer, we approach development of products with customer requirements at the heart of our operations. It's particularly great to see how the North American market for off-road diesel engines has increased since the last CONEXPO show of 2014, and we expect this momentum to continue in the future."

Volvo Penta's CONEXPO displays focused on engines ranging from 5 to 16 litres. The D5 series of 5L engines are equipped with a common-rail fuel system and, according to the company, are some of the most powerful four-cylinder diesel engines available. They are offered in a range from 143 to 218 hp, meaning they perform on par with larger six-cylinder engines and offer exceptional torque at low rpm.

New three-cylinder engines from Hatz
Hatz, the manufacturer of the established 4H50 engines, is introducing three-cylinder models targeted at compact applications. The new three-cylinders aim to be an ideal solution for the compact machine class up to 50 hp. The goal is not only to house engines in a compact installation space, but also to ensure the form and operation of the machine remains unchanged. If exhaust emission aftertreatment becomes necessary, the smaller size and reduced raw emissions of the smaller engines are a benefit.

The Hatz 3H50, at 1.5L and up to 2,800 rpm, will replace the 2.5L engines in the future. Torque and response behavior are considerably superior to the present generation. At the same time, fuel consumption is significantly reduced. The lightweight Hatz 3H50TI doesn't need any exhaust emission aftertreatment; nevertheless, the engine achieves compliance with Stage IIIA and Tier 4 interim standards in the power range from 25 to 50 hp. With a maximum torque of 146 lb.-ft. (at 1,600 to 2,200 rpm) and up to 62 hp, the Hatz 3H50TI is the top performer of the Hatz three-cylinders. Options are available that add EGR and DOC to the engines, and there is a version with DPF if required.

MTU showcases Stage V solutions
Rolls-Royce brought its MTU engine brand to CONEXPO and showed a range of engines as well as its Stage V approach for several of its products.

In addition to engines, MTU also showcased its Stage V SCR aftertreatment solution for the MTU Series 1000, 1100, 1300 and 1500 engines.

MAN Engines increases Americas commitment
Building on a strong foundation based in years of North American presence, Germany's MAN Engines used CONEXPO to expand its visibility and affirm its commitment to the North American market. 

MAN Engines provides the technology and products for new partnerships in the field of construction and mining vehicles. MAN Engines covers a power range from 294 to 816 kW (400 to 1,110 hp) with the three engine series D2676, D3876 and D2862 with 12.4-, 15.2- and 24.2L capacities. The engine dynamics are adjusted to match the particular application using wastegate turbocharging or variable turbine geometry. In this way, MAN diesel engines provide sufficient charging pressure and dynamics for wheel loaders, excavators, dump trucks, and mobile cranes, even at low revs in the efficient engine speed range.

New platforms for Perkins range
Construction equipment manufacturers will have new options thanks to the addition of four new product platforms by Perkins. The company is adding engines in the 9-18L range, with a power offering of up to 800 hp.

"Our four new engine platforms are specifically designed to meet our customers' strategic and commercial requirements," said Andy Zuckerman, Americas Sales and Distribution Director. "We've developed a modular engine architecture which delivers the right performance, while enabling customers to develop single machine designs adaptable to multiple emissions standards."

The addition of a 9L 1700 Series, a 13L 2200 Series, a 15L 2500 Series and an 18L 2800 Series more than doubles the power range previously offered by Perkins, extending it from 8.2 to 597 kW (11 to 800 hp). From the compact 0.5L to the powerful 18L engines, equipment manufacturers can take advantage of Perkins' comprehensive engine range, saving themselves time and money by using just one supplier for all their engine needs, across their global machine lineup.

One example is the 9.3L 1700 Series, a six-cylinder turbocharged and aftercooled unit with direct injection and a fully electronic control system that will meet EU Stage V, U.S. EPA Tier 4 Final emission standards. With a power range of 250-340 kW (335-456 hp), it provides a strong option for construction applications, and has been validated to deliver optimal performance in the harshest working environments. 

Technology - often driven by emissions regulations - is always advancing in the diesel engine sector. The many companies producing engines for industrial use put plenty of time and energy into research and development to improve their products and save their customers money. Through 2017, we have seen a wide number of updates and new launches, many to coordinate with the upcoming Stage V regulations in Europe.

From new engines on the upper end of the power range, such as those introduced by Perkins and John Deere, to broad updates with new emissions technology, like the new line of Deutz products, to engines that are moving companies like Kubota into entirely new power ranges, 2017 has thus far been a strong year for the development of the diesel engine. 

John Deere launches new 13.6L engine
CONEXPO was the launching point for John Deere's next generation of engines, with the debut of the company's 13.6L engine for both their own machines and OEM applications.

Deere has equipped the new engine with an integrated high-pressure common-rail fuel system, reducing fuel consumption significantly at rated speed. Diesel exhaust fluid consumption has been reduced through design enhancements that improved the combustion process. In addition, designers have made the engine more compact and reduced its size and weight compared to other engines in the power range.

"Our engineers developed the new 13.6L engine to meet the power and packaging needs for a wide array of heavy-duty applications," said John Piasecki, director of marketing, sales and customer support for John Deere Power Systems. "The 13.6L engine demonstrates our ongoing commitment to recognizing and exceeding our customers' expectations. John Deere dedicated extensive internal resources to the clean sheet design of this engine to provide our customers with a power solution that surpasses standards in reliability and durability."

The 13.6L engine offers a maximum variable speed power rating over 500 kW (684 hp) and employs the same proven technologies as other engines in the John Deere lineup, particularly full-authority electronic controls, cooled exhaust gas recirculation (EGR) and a high-pressure common-rail fuel system. Single- and dual-turbocharger configurations offer OEM customers improved packaging and greater application flexibility. "These technologies are the key to our ability to meet emission requirements and still live up to our customers' power and packaging expectations," said Piasecki.

DD8 medium-duty joins Detroit Diesel lineup
"Daimler Trucks North America is excited to add the Detroit DD8 engine to its Medium-Duty engine lineup," said Kary Schaefer, General Manager, Marketing and Strategy for the company, adding that the engine "is ideally suited for the vocational applications across the Daimler Trucks North America family of products."

With a horsepower range of 260-350 hp and torque running from 660-1,050 lb.-ft., the DD8 expands on a medium-duty platform introduced in 2016 with the DD5. The goal is to provide customers with fuel efficiency and long maintenance intervals. In addition, the engine is launching with both engine and transmission PTO options to facilitate many vocational options. The DD8 will initially be available in the Freightliner M2106, 108SD and 114SD models.

"The medium-duty engine options are all about giving our customers added value when making their engine selections," Schaefer said. "The DD5, and now the DD8, will lead the industry in uptime and fuel efficiency. With these advantages as well as Virtual Technician, we are providing our customers a smart business solution."

Vehicles equipped with the DD8 will feature Detroit Connect Virtual Technician remote diagnostic service. Virtual Technician helps fleets make informed maintenance decisions, so that they only service their vehicles when needed.

Deutz plans for the future with engine launches
For Deutz, CONEXPO was an opportunity to display its expanded portfolio of engines, which now have a range from 2.2 to 18 litres. Notably, Deutz introduced a pair of four-cylinder diesels, the TCD 5.0 and TCD 9.0.

The TCD 5.0 will be introduced worldwide in 2019 to meet the next EU Stage V emissions standard. The engine will also comply with U.S. Tier 4 Final. This particularly compact, turbocharged and charge-air-cooled, 5L diesel engine generates 135-200 hp (100-150 kW) and 890 Nm of torque. The engine also conforms to the downsizing principle by producing more power from a smaller cubic capacity, enabling customers to replace larger displacement engines with more fuel-efficient and compact four-cylinder engines. The TCD 5.0 is a brand-new design with minimum pipework and fewer components for less complexity and maintenance. The new TCD 9.0 9L engine generates 300-400 hp (200-300 kW) and 1,700 Nm of torque. Its highly compact design makes it easy to install in a wide variety of applications, particularly excavators and wheel loaders.

The company is also introducing two six-cylinder engines, the TCD12.0 and 13.5, generating up to 400 kW (536 hp) and 2,500 Nm and up to 450 kW (600 hp) and 2,800 Nm, respectively. These engines, along with the TCD 9.0 and the future TCD 18.0, are the product of a collaborative partnership with the Liebherr Group.

Cummins award-winning X15 Efficiency Series
The Truck Writers of North America have recognized the Cummins X15 Efficiency Series diesel with their 2016 Technical Achievement Award. Presented in March, the engine was selected by a panel of industry journalists from Canada and the U.S. for its advanced combustion design.

"Cummins is honoured to receive the Technical Achievement Award for our 2017 X15 Efficiency Series, and it is especially relevant to us that this recognition comes from truck industry writers, many of whom have experienced the enhanced driveability and responsive performance of the X15 engine first hand," said Tim Proctor, Cummins X15 engine system technical leader.

He added that the 14.9L diesel gains three percent in fuel efficiency over the preceding model, the ISX15, through improvements to air-handling, combustion efficiency, reduced parasitic losses and advanced electronics, while maintenance should cost 40 percent less than previous engines over five years. 

Cummins redesigned its ISX15 to meet 2017 federal greenhouse gas and fuel economy requirements, and introduced two models called X15 Performance and X15 Efficiency. The Efficiency version employs an Atkinson Cycle in its valve action that adds fuel efficiency important to fleet managers.
