JCB today announced the next stage of its engine strategy with the news it has forged a partnership with Kohler to produce engines for its compact equipment.

JCB is adopting a range of fuel-efficient Tier 4 Final/Stage IIIB engines from Kohler’s Global Power Group for many of its compact machine lines. The water-cooled Kohler Direct Injection (KDI) engines - which will be branded JCB Diesel by Kohler - meet the next stage of emissions regulations without the need for a DPF, much like JCB's Ecomax engine line.

Today, the first JCB machine to be fitted with the new engine - a JCB 35D 4x4 Teletruk - was unveiled at the RWM waste management show at the Nation Event Centre (NEC) in Birmingham, UK. The Teletruk is JCB’s innovative and award-winning telescopic forklift, saving customers time and money with its unique ability to reach forwards, enabling single side loading and accurate placement of loads.

JCB’s Director of Engine Programs Alan Tolley says, “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. 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 European-built engines will be progressively introduced in JCB products, including the Teletruk TLT35D; 406 and 409 compact wheel loaders; 135, 155, 175, 190 and 205 skid steers; 150T, 190T and 205T compact track loaders; and select compact excavator models.

High Torque Output
 

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. Fuel consumption is up to 15% better than a similar output engine equipped with lower injection pressures and a DPF.

There are two 1.9-liter three-cylinder engines, the KDI 1903M and the KDI 1903TCR, delivering 31 kW (41 hp) with 133 Nm of torque and 42 kW (56 hp) with 225 Nm of torque respectively. The 2.5-liter, four-cylinder KDI 2504M and KDI 2504TCR deliver 36.4 kW (48.8hp) with 170 Nm and 55.4 kW (74 hp) with 300 Nm. The engines meet all JCB standards, with 500-hour maintenance intervals available on all models. Strong, low-rpm torque characteristics will result in improved machine performance and added engine response, delivering improved productivity for JCB customers.

“Innovation is a common thread running through the design of this completely new family of engines by Kohler,” says Giuseppe Bava, Chief Executive Officer of Kohler’s diesel engine Business Unit. "They feature highly advanced technology for clean combustion and limited emissions without the use of aftertreatment systems. The KDI engine family is designed to be compact, yet providing best-in-class performance.”
