The new standards will come into force in 2019 for engines below 56 kW (76 hp) and above 130kW (177 hp).
JCB Power Systems will use a combination of next generation particulate control technology, using diesel oxidation catalysts (DOC), integrated DPF & selective catalytic reduction (SCR) to meet EU Stage V regulations. They will take effect a year later, in 2020, for engines in the 56 to 129 kW (76 to 130 kW) range. The standard not only calls for a further reduction in particulate matter, it also broadens the regulations to include a much wider range of engine powers and applications. EU Stage V includes other fuel types, such as natural gas, along with static machinery such as generators. All Stage V JCB engines have been designed to fit beneath existing engine canopies and will not require redesign of machinery to accommodate.
JCB’s particulate control technology features low particulate combustion, oxidation catalyst, filter and integrated engine and regeneration control system. It’s been designed to be a completely integrated system that’s highly reliable, highly effective and invisible to the customer. These are compact systems that are installed within the existing machines’ engine bays. In operation, they require no operator intervention or additional service attention.
JCB’s 3.0-litre Dieselmax 430 engine will continue to provide an output of 55kW (74hp) and 410Nm of torque. The engine will benefit from the addition of an electronic wastegate turbocharger and a compact DOC and filter system. The new 3.0-litre engine will feature auto-stop technology and up to 1,000-hour service intervals, reducing operating costs for customers. The company’s 4.8-litre engine, which produces 81-129kW (108-174hp) with torque of between 516Nm and 690Nm, features a compact after-treatment system, using JCB’s particulate control technology with an SCR filter. This engine also benefits from the adoption of a wastegate turbocharger and auto-stop technology to reduce fuel consumption. It will be used in JCB’s excavators and loading shovels, as well as backhoe loaders, Loadalls and in other applications. Source
