JCB Opts For Kohler Diesels In Compact Machines

Posted on September 10, 2013

Calling it the next stage of its engine strategy, JCB said it has forged a partnership with Kohler’s Global Power Group and will use Kohler diesels in several of its compact machine lines.

The water-cooled Kohler Direct Injection (KDI) engines – which will be branded JCB Diesel by Kohler – are designed to meet the next stage of emissions regulations without the need for a diesel particulate filter (DPF). The first JCB machine to be fitted with the new engine, a JCB 35D 4x4 Teletruk forklift, has been unveiled at the RWM waste management show at the NEC in Birmingham, England.

“The decision to partner with Kohler to develop engines for JCB compact machines was driven by the synergy in the technologies used by JCB and Kohler to achieve stringent Tier 4 Final emissions legislation,” said Alan Tolley, JCB’s director of Engine Programmes. “Kohler’s achievement of Tier 4 final without the need for a bulky DPF is fully in line with our own engine strategy and allows our designers maximum flexibility when it comes to meeting machine design and packaging requirements. These highly efficient engines will offer our customers improved performance and lower fuel consumption.”

The KDI engines, which are built at Kohler’s Lombardini facilities in Italy, will be progressively introduced in JCB products, including midi excavators, the Teletruk TLT35D, 406 and 409 compact wheeled loaders, the 190 and 205 skid steers and 190T and 205T compact tracked loaders, smaller 135, 155 and 175 skid steers and TM180 and TM220 articulated wheeled loading shovels.

The KDI engines incorporate a common rail fuel injection system working at 2000 bar (29,000 psi), cooled exhaust gas recirculation (EGR), four valves per cylinder and a diesel oxidation catalyst (DOC) within the exhaust system. Fuel consumption is up to 15% better than a similar output engine equipped with lower injection pressures and a DPF, JCB said.

There are two 1.9 L three-cylinder engines, the KDI 1903M and the KDI 1903TCR, delivering 31 kW (41 hp) with 133 Nm (98 lb. ft.) of torque and 42 kW (56 hp) with 225 Nm (166 lb. ft.) of torque respectively. The 2.5 L, four-cylinder KDI 2504M and KDI 2504TCR deliver 36.4 kW (48.8hp) with 170 Nm (125 lb.ft.) torque and 55.4 kW (74 hp) with 300 Nm (221 lb. ft.) torque.
