JCB announces next stage in engine strategy development

The JCB Teletruk 35D 4 x4 is the first JCBmachine to be fitted with a JCB Diesel by Kohler engine.

JCB has announced the next stage of its enginestrategy with the news it has forged a partnership with a leading globalmanufacturer to produce engines for its compact equipment.

JCB has gone from a new entrant in enginemanufacturing to an innovative global producer, reports the company, with the first JCB enginerolling off the production line in the UK in November 2004. Since thenproduction has been extended to JCB Indias HQ at Ballabgarh and to date morethan 250,000 engines have been produced globally.

The innovativeJCB Ecomax engine, which meets EU Stage IIIB/US Tier 4i emissionsstandards without the need for a diesel particulate filter (DPF) or externalexhaust after treatment, went into production earlier this year.

Now JCB has announced it is adopting a range offuel-efficient Stage IIIB/Tier 4 Final engines from Kohlers Global PowerGroup, for many of its compact machine lines. The water-cooled Kohler DirectInjection (KDI) engines – which will be branded JCB Diesel by Kohler -meet the next stage of emissions regulations without the need fora diesel particulate filter (DPF).

The first JCB machine to be fitted with the newengine, a JCB 35D 4×4 Teletruk, was unveiled at the RWM waste management showat the NEC in Birmingham. The Teletruk is JCBs innovativetelescopic forklift which has the ability toreach forwards, enabling single side loading and accurate placement of loads.

JCBs director of engine programmes Alan Tolley said;The decision to partner with Kohler to develop engines for JCB compactmachines was driven by the synergy in the technologies used by JCB and Kohlerto achieve stringent Tier 4 Final emissions legislation. Kohlers achievementof Tier 4 Final without the need for a bulky DPF is fully in line with our ownengine strategy and allows our designers maximum flexibility when it comes tomeeting machine design and packaging requirements. These highly efficientengines will offer our customers improved performance and lower fuelconsumption.

The European-built engines will be progressivelyintroduced in JCB products, including midi excavators, the Teletruk TLT35D, 406and 409 compact wheeled loaders, the 190 and 205 skid steers and 190T and 205Tcompact tracked loaders, smaller 135, 155 and 175 skid steers and TM180 andTM220 articulated wheeled loading shovels.

High Torque Output
The KDI engines use a common-rail high pressure fuel injectionsystem, cooled exhaust gas recirculation (EGR),four valves per cylinder and a diesel oxidation catalyst (DOC) within theexhaust system. Fuel consumption is said to be up to 15% better than that of a similar outputengine equipped with lower injection pressures and a DPF.

There are two 1.9-litre 3-cylinder engines, theKDI 1903M and the KDI 1903TCR, delivering 31kW (41hp) with 133Nm of torque and42kW (56hp) with 225Nm of torque respectively. The 2.5-litre, 4-cylinder KDI2504M and KDI 2504TCR deliver 36.4kW (48.8hp) with 170Nm and 55.4kW (74hp) with300Nm. The engines meet all JCB standards, with 500-hour maintenance intervalsavailable on all models. Strong, low-rpm torque characteristics will result inimproved machine performance and added engine response, delivering improvedproductivity, said the company.

Innovation is a common thread running through thedesign of this completely new family of engines by Kohler, said Giuseppe Bava,Chief Executive Officer of Kohlers diesel engine business unit. They featurehighly advanced technology for clean combustion and limited emissions withoutthe use of after-treatment systems. The KDI engine family is designed to becompact, yet providing best in class performance.

Kohler Engines president Tom Cromwell, added:Kohler is extremely proud to be appointed as JCBs engine supply partner for awide range of construction equipment with the Kohler KDI engines. Reflectingthe significant investment made by Kohler within diesel engine innovation andtechnology, these compact engines enable the machines to meet the stringent EUStage IIIB and EPA Tier 4 Final emission regulations without the use of a DPF,while delivering significant fuel savings for JCB customers. This alignsperfectly with JCBs wider engine strategy.
