JCB POWER SYSTEMS OUTLINES TIER 4 FINAL ENGINE STRATEGY

JCB Power Systems, manufacturer of the award-winning Dieselmax and Ecomax engine ranges, will unveil its complete US EPA Tier 4 Final emissions solution at this year’s Conexpo-Con/Agg exhibition in Las Vegas (Booth 83918, South Hall).

The highly efficient JCB Ecomax engine line-up meets the Tier 4 Final standards without the use of a costly diesel particulate filter (DPF), saving customers cost and service time. This engineering feat has been achieved through the use of highly efficient combustion technology, that minimizes exhaust emissions within the engine, rather than relying on costly after-treatment to clean up gases.

JCB’s Ecomax engines have been recalibrated for Tier 4 Final, resulting in a further 5% fuel saving compared to previous models. A compact selective catalytic reduction (SCR) solution with a Urea-based additive will be used on engines above 74hp (55kW) . The SCR catalyst is incorporated into a single exhaust muffler, in most cases replacing the existing exhaust box, to provide a ‘one-can’ solution.

With no requirement for a bulky DPF, the JCB Power Systems engine package is particularly compact, making it easier to install in a wide variety of machines without costly alterations to bodywork.

“We have continued to use innovative in-cylinder technology to reduce exhaust emissions within the JCB Ecomax engine, rather than resorting to a DPF,” said Alan Tolley, Director of Engine Programs at JCB Power Systems. “Through recalibration, and in some cases the addition of our one can SCR solution, we have delivered a range of technologically advanced engines that meet the requirements of Tier 4 Final within existing packaging requirements.

 “Our customers will also welcome the fact that these engines deliver up to 5% higher fuel efficiency, reducing running costs and boosting productivity. Plus there will be no concerns in the used equipment market, maintaining the strong residual values enjoyed by all JCB equipment.”

JCB is also unveiling four cylinder Ecomax engines at Tier 4 Final for Industrial Power Units and for G-Drive installation. These engines are specifically designed for the US market to meet EPA requirements. Lower tier variants are available for less regulated territories.

JCB Power Systems is increasing its offering in the North American market, with the first US showing of the 7.2-liter, six-cylinder Dieselmax engine, which is currently available at Tier 2 and Tier 3 emission levels. With specific fuel consumption as low as0.31 lb/hp-hr, the six-cylinder engine delivers power outputs of 187hp (140kW) to 284hp (212kW). The six-cylinder engine will adopt a similar Tier 4 Final emission solution, providing customers with a highly efficient, low fuel consumption powerplant.

JCB Power Systems is based in Derbyshire, England, with additional production facilities in Delhi, India. The company produces a range of off-highway engines with displacements of 4.4 – 7.2 litersand power outputs of 74-285hp (55-212kW) .
