New Engines JCB Power Systems has made one
of the biggest investments in its histo- ry to develop a clean diesel engine for the off-highway sector in readiness for incoming emissions legislation. The announcement of the new devel- opment also comes at a key time, as the company continues to strengthen its global distribution network for OEM engine sales. JCB Power Systems has invested around £ 80 million (approximately US$98 million) in researching and developing a new combustion system for the new JCB Ecomax T4 4. 4 L engine — the latest generation of JCB Dieselmax engines. The investment has delivered a system that eliminates the need for any exhaust aftertreat- ment, the company said. The engine is now undergoing full in-field testing before going into pro- duction in 2012 to meet Tier 4 inter- im/Stage 3b legislation. Alan Tolley, JCB’s director of engine programs, said, “The expecta- tion for the first part of Tier 4
interim/Stage 3b legislation was that to achieve these really low particulate levels you needed to fit a DPF. “But when you look at that technolo- gy for our particular part of the market, namely midrange construction equip- ment, we see there are some real dis- advantages with that solution, in partic- ular increased fuel consumption through increased backpressure to the engine. Also, in many applications load cycles are light and the DPF doesn’t self-regenerate, so you have to force it to do so and it needs fuel to do it.
No diesel particulate filters for JCB.
