PowerTech E and PowerTech M Engines in Full Production
WATERLOO, IA (November 27, 2007) - John Deere Power Systems (JDPS) is pleased to announce that three new models of their 4.5L engine have received Tier 3/Stage III A certification from the Environmental Protection Agency (EPA) and the European Union (EU). The turbocharged PowerTech(TM) E 4.5L, the turbocharged PowerTech M 4.5L, and the turbocharged and air-to-air aftercooled PowerTech M 4.5L engines are the latest models from the complete lineup of John Deere Tier 3/Stage III A engines to be certified.
"The 4.5L engine is one of our most popular models, so we're very excited to offer these certified engines that have the same durability and reliability our customers have come to expect from John Deere," said Doug Laudick, Tier 3 product manager for JDPS. "This is also the first time John Deere will offer an electronically controlled engine under 100 horsepower, so it's a big step to bring the advantages of electronics to lower-horsepower applications."
PowerTech E 4045T
The turbocharged PowerTech E 4.5L engine features a power range of 63 kW - 74 kW (85 hp - 99 hp) and is the first John Deere engine under 100 hp to be electronically controlled. This engine comes with a two-valve cylinder head and incorporates a high-pressure common-rail fuel system, full-authority electronic controls, a multiple injection strategy and a fixed geometry turbocharger, as well as all the performance of Tier 2/Stage II engines and more.
These technologies enabled John Deere to achieve their goals for Tier 3/Stage III A PowerTech E engines, including maintained or improved peak torque, low-speed torque and transient-response time.
The PowerTech E 4.5L engine's full-authority electronic controls also enable it to offer improved cold-start performance, precise engine-speed control, torque-curve shaping and more. Electronic controls increase productivity, improve fuel economy, lower total installed costs and reduce ownership costs.
In addition to the turbocharged PowerTech E 4.5L, John Deere also offers a turbocharged and air-to-air aftercooled PowerTech E 4.5L engine that received Tier 3/Stage III A certification from the EPA and EU in the summer of 2006. These engines offer a power range of 86 kW - 104 kW (115 hp - 140 hp).
PowerTech M 4045T and 4045H
The turbocharged PowerTech M 4.5L engine features a power range of 56 kW - 63 kW (75 hp - 85 hp), and the turbocharged and air-to-air aftercooled PowerTech M 4.5L engine features a power rating of 74 kW (99 hp). PowerTech M 4.5L engines feature economy of design, a two-valve cylinder head, a fixed geometry turbocharger and a mechanical rotary pump fuel system, plus all the performance of Tier 2/Stage II.
The simple design and mechanical controls of PowerTech M engines give OEMs and end users flexibility and cost savings while maintaining the same platform as Tier 2/Stage II engines. When compared to their Tier 2/Stage II counterparts, PowerTech M engines offer improved or maintained peak torque levels and transient-response time.
John Deere has taken a multi-platform approach to emissions regulations. JDPS offers three engine technology options: PowerTech Plus, PowerTech E and PowerTech M, which are differentiated by the level of technology employed. PowerTech Plus engines feature cooled exhaust gas recirculation, a variable geometry turbocharger, a state-of-the-art engine control unit, full authority electronic controls, and an electronic unit injector fuel system (13.5L) or a high-pressure common-rail fuel system (4.5L, 6.8L, 9.0L). PowerTech E engines feature a fixed geometry turbocharger, full-authority electronic controls, and a high-pressure common-rail fuel system (4.5L, 6.8L) or an electronic unit pump fuel system (2.4L, 3.0L). PowerTech M engines feature economy of design, a fixed geometry turbocharger, and a mechanical unit pump fuel system (2.4L) or a mechanical rotary pump fuel system (4.5L).
