PowerTech E™ Engines Offer Improved Performance
WATERLOO, IA (January 22, 2007) — John Deere Power Systems (JDPS) is pleased to announce the production of the Tier 3/Stage III A certified PowerTech E™ family of off-highway diesel engines that will offer customers improved performance over their Tier 2/Stage II counterparts.
The PowerTech E engine lineup includes four displacement options:
- The 6.8L offers a power range of 104 kW – 149 kW (140 hp – 200 hp)
- The 4.5L offers a power range of 63 kW – 104 kW (85 hp – 140 hp)
- The 3.0L offers a power range of 48 kW – 74 kW (65 hp – 99 hp)
- The 2.4L offers a power range of 45 kW – 60 kW (60 hp – 80 hp)
JDPS has been in production with the PowerTech E 6.8L and 4.5L since summer 2006; full production of PowerTech E 3.0L and 2.4L is set to follow in summer 2007, months in advance of the U.S. Environmental Protection Agency (EPA) and European Union (EU) emissions regulations affecting engines below 75 kW.
Both the EPA and the EU have certified the PowerTech E 6.8L and 4.5L engines. The four PowerTech Plus™ engine models received their certifications during 2005 and 2006.
“Now that we have certified not only our PowerTech Plus engines but also our PowerTech E 6.8L and 4.5L engines, we’re well prepared to offer a wide variety of environmentally friendly engine options for John Deere and OEM applications that don’t compromise on performance,” said Mike Weinert, director of engine engineering for JDPS.
The Benefits of PowerTech E
The PowerTech E line comes with the legendary reliability that John Deere customers have come to expect, as well as many performance characteristics that are better than those of their Tier 2/Stage II counterparts. They boast the same or higher peak torque, more low-speed torque, better transient-response time and excellent fuel economy. Their full-authority electronic controls also enable them to offer improved cold-start performance, precise engine-speed control, torque-curve shaping and more. Electronic controls increase productivity, lower total installed costs and reduce ownership costs. In addition, initial results indicate that PowerTech E engines are as fuel efficient as their Tier 2/Stage II counterparts and, in some cases, use less fuel than many competitors’ Tier 3/Stage III A engines.
“Many end-users expect that engine performance has been negatively impacted as the engines were required to meet Tier 3 emissions regulations, but with PowerTech E engines, that isn’t the case,” said Doug Laudick, product manager for JDPS. “These engines continue to offer many end-user benefits and a competitive total installed cost that John Deere engines have always delivered.”
One of the key aspects of the PowerTech E lineup is the fact that it brings the benefits of electronics to engines that are less than 100 hp. With its Tier 2 lineup, electronic options for John Deere engines went down to 110 hp, but with Tier 3, John Deere customers can get electronically controlled engines down to 60 hp.
John Deere utilized various technologies to meet their Tier 3/Stage III A performance goals with PowerTech E engines. These engines come with a two-valve cylinder head, are turbocharged or air-to-air intercooled and incorporate a high-pressure common-rail fuel system (6.8L and 4.5L engines) or an electronic unit pump fuel system (3.0L and 2.4L engines), full-authority electronic controls, multiple injection strategy, and a fixed geometry turbocharger.
The Rest of the PowerTech™ Family
The PowerTech E engines are not the only Tier 3/Stage III A option from JDPS. John Deere offers three engine lines in the PowerTech family — PowerTech M™, PowerTech E and PowerTech Plus — to meet different customers’ varying needs.
The PowerTech M lineup includes two displacement options:
- The 4.5L offers a power range of 56 kW – 74 kW (75 hp – 99 hp)
- The 2.4L offers a power range of 31 kW – 37 kW (42 hp – 49 hp)
The PowerTech Plus lineup includes four displacement options:
- The 13.5L offers a power range of 261 kW – 448 kW (350 hp – 600 hp)
- The 9.0L offers a power range of 168 kW – 298 kW (225 hp – 400 hp)
- The 6.8L offers a power range of 134 kW – 205 kW (180 hp – 275 hp)
- The 4.5L offers a power range of 111 kW – 129 kW (149 hp – 173 hp)
“There’s no such thing as a one-size-fits-all solution to the Tier 3/Stage III A challenge,” Laudick says. “As we reviewed market needs with many of our OEM customers, we realized we could better serve them by offering solutions tailored for the application.”
The main difference among these three engine lines is the level of emissions-control technology employed. PowerTech Plus engines feature cooled exhaust gas recirculation, a variable geometry turbocharger, a state-of-the-art engine control unit, and an electronic unit injector fuel system (13.5L) or a high-pressure common-rail fuel system (9.0L, 6.8L, 4.5L), all integrated to provide industry-leading fuel economy.
PowerTech E engines are a simple emissions solution that feature a fixed geometry turbocharger, full-authority electronic controls, and a high-pressure common-rail fuel system (6.8L and 4.5L) or an electronic unit pump fuel system (3.0L and 2.4L). The PowerTech E line also boasts performance standards similar to those of the more complex PowerTech Plus engines. PowerTech M engines feature economy of design, a fixed geometry or wastegated turbocharger, mechanical controls, a mechanical unit pump fuel system (2.4L) or a mechanical rotary pump fuel system (4.5L), plus all the performance of Tier 2/Stage II. These engines are either naturally aspirated (2.4L), turbocharged (4.5L and 2.4L) or air-to-air intercooled (4.5L).
PowerTech M engines are the simplest Tier 3/Stage III A solution in the PowerTech family, and they are perfect for less demanding and lower-horsepower applications. The PowerTech M 4.5L and 2.4L will go into full production in summer 2007, months in advance of the January 2008 Tier 3 deadline for engines 50 hp to 100 hp. In fact, some engines from the PowerTech M and PowerTech E lines have already demonstrated Interim Tier 4 and Stage III A capabilities and will be in compliance before those levels take effect.
The simple design and mechanical controls of PowerTech M engines give OEMs and end users additional flexibility and cost savings while maintaining the same engine platform as Tier 2/Stage II engines. When compared to their Tier 2/Stage II counterparts, PowerTech M engines provide such end-user benefits as faster torque rise, maintained or improved transient-response time, higher peak torque speed, a new power bulge feature on the 4.5L and the lowest installed costs. Additional benefits include their compact size, reduced noise and a 500-hour oil change.
Laudick also noted that the PowerTech family of engines is the foundation John Deere will build on for future U.S. EPA and EU regulations. “Our Tier 3 engine platforms will be the basis for meeting Tier 4 emissions levels beginning in January 2008,” Laudick said. “We have already begun exploring a number of technologies, including additional in-cylinder and aftertreatment solutions, that will be applied to the existing Tier 3 platforms.”
