EPA and EU Certification For Deere 4.5L Diesels

Posted on November 28, 2007

John Deere Power Systems (JDPS) said that three new models of its 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 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.

“This is 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,” said Doug Laudick, Tier 3 product manager for JDPS.

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.

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, Deere said.

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).

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 a two-valve cylinder head, a fixed geometry turbocharger and a mechanical rotary pump fuel system.
