JCB has announced a partnership with Kohler for small diesel engines of three- and four-cylinder engines from 31 to 55 kW for the company's range of compact construction equipment. The water-cooled Kohler Direct Injection (KDI) engines, which will be branded JCB Diesel by Kohler, meet the forthcoming Tier 4 Final emissions regulations without the need for a diesel particulate filter (DPF). The European-built engines will be progressively introduced in JCB products, including midi excavators, the TLT35D Teletruk, a compact telescopic forklift, 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 loaders. The first machine to be fitted with the new engines is the TLT35D 4x4 Teletruk. The KDI engines use a Common Rail fuel injection system working at 2,000 bar pressures, cooled exhaust gas recirculation (EGR), four valves per cylinder and a diesel oxidation catalyst (DOC) within the exhaust system.
