JCB says it is boosting the fuel efficiency, productivity and performance of its heavier crawler excavators with the installation of Tier 4 Final diesel engines.
The six-cylinder, 7.7litre MTU 6R1000 engine, already proven in JCB’s largest wheeled loader, will be used in the JS300, JS330 and JS370.
The diesel engine is a turbo-charged and inter-cooled power plant delivering 180kW in the JS300 and 210kW for the JS330 and JS370 models.
The machines incorporate Selective Catalytic Reduction (SCR) within the exhaust system, with dosing of a urea-based Diesel Exhaust Fluid (DEF) to reduce NOx emissions by almost 90%.
The company says that this system allows the engine to meet Tier 4 Final without having to use a Diesel Particulate Filter (DPF), reducing cost and service complexity for the customer.
Their introduction means fuel savings for customers of up to 10% on the JS370 and 5% on the JS300 and JS330.
