John Deere expands Tier 4 Final engine range

Niels Tholen - 23 April 2013

John Deere has introduced its  newest Tier 4 Final engine, the PWL 4.5L engine. The engine will not use a Diesel Particulate Filter (DPF) but instead rely on Selective Catalytic Reduction (SCR), Diesel Oxidation Catalyst (DOC) and cooled Exhaust Gas Recirculation (EGR) technology to comply with Tier 4 Final emission standards.

The 4.5 liter engine was introduced at Bauma last week and complements the already announced engine line-up by providing a 85 hp to 140 hp engine. For engines ranging from 48 hp to 75 hp, John Deere will offer DOC/DPF technology while 76 hp to 140 hp engines use SCR, DOC and cooled EGR. Engines above 140 hp will be equipped with similar technology and the addition of DPF.

John Piasecki, Director of Marketing, Sales and Customer Support for John Deere Power Systems, said:  "we believe the elimination of the DPF will serve OEMs and end users well in the very competitive 75 hp to 140 hp segment, balancing packaging and product cost considerations with performance and operating cost requirements. The Integrated Emissions Control system in its various configurations represents technology optimization that achieves emissions compliance, and delivers the power, performance, ease of operation, fluid efficiency, reliability, durability and economical operating cost customers expect from John Deere."
