JCB power systems ready for Stage V emissions standard

JCB Power Systems will use a combination of next generation particulate control technology, incorporating diesel oxidation catalysts (DOC), integrated DPF and selective catalytic reduction (SCR) to meet European Stage V emissions regulations. The new standards will come into force on January 1, 2019, for engines below 56kW and above 130kW. They will take effect a year later, on January 1, 2020, for engines in the 56-129kW 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. JCB Power Systems starts from a position of strength, having developed highly efficient combustion technologies within its engine ranges. All Stage V engines have been designed to fit beneath existing engine canopies and will not require redesign of machinery to accommodate.

“JCB engines have low emission, high efficiency combustion systems developed for Stage IIIB and Tier 4,” said Alan Tolley, JCB’s Group Director of Engines. “This means that we started development for Stage V from a good position. 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 our 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) along with a sturdy 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, significantly reducing operating costs for customers.

“At 55kW the JCB 430 Dieselmax engine, equipped with JCB’s new integrated particulate control technology, will be used in many of JCB’s mid-range machines,” said Mr Tolley.

“This new highly efficient, high torque engine will offer cost of ownership benefits to our customers, with lower fuel consumption, extended service intervals and auto-stop technologies.”

The company’s 4.8-litre engine, which produces 81-129kW (108-174hp) and boasts torque outputs of 516Nm through to 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.

“At 81-129kW, the JCB 448 engines, fitted with JCB’s new combined particulate control and NOx reduction technology, will be used in JCB’s excavators and loading shovels, as well as backhoe loaders, Loadalls and in other applications,” said Mr Tolley.
