JCB announced the next stage of its engine strategy with the news it has forged a partnership with a leading global manufacturer to produce engines for its compact equipment.
JCB has gone from a new entrant in engine manufacturing to an innovative global producer with the first JCB engine rolling off the production line in the UK in November 2004. Since then production has been extended to JCB India’s HQ at Ballabgarh and to date more than 250,000 engines have been produced globally.
JCB went into production this year with the JCB Ecomax engine, which meets U.S. Tier IV/EU Stage IIIB Interim emissions standards without the need for a diesel particulate filter (DPF) or external exhaust after treatment.
Now JCB has announced it is adopting a range of fuel-efficient Tier IV 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.
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 telescopic forklift, saves customers time and money with its ability to reach forwards, enabling single side loading and accurate placement of loads, according to the manufacturer.
JCB’s Director of Engine Programs Alan Tolley said: “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 IV Final emissions legislation. Kohler’s achievement of Tier IV 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 percent better than a similar output engine equipped with lower injection pressures and a DPF.
There are two 1.9-L three-cylinder engines, the KDI 1903M and the KDI 1903TCR, delivering 41 hp (31 kW) with 133Nm of torque and 56 hp (42 kW) with 225Nm of torque respectively. The 2.5-L, four-cylinder KDI 2504M and KDI 2504TCR deliver 48.8 hp (36.4 kW) with 170Nm and 74 hp (55.4 kW) with 300Nm.
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, according to the manufacturer.
“Innovation is a common thread running through the design of this completely new family of engines by Kohler,” said 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 after-treatment systems. The KDI engine family is designed to be compact, yet providing best in class performance.”
Tom Cromwell, president at Kohler Engines, added: “Kohler is extremely proud to be appointed as JCB’s engine supply partner for a wide range of construction equipment with the Kohler KDI engines. Reflecting the significant investment made by Kohler within diesel engine innovation and technology, these compact engines enable the machines to meet the stringent EPA Tier IV Final and EU Stage IIIB emission regulations without the use of a DPF, while delivering significant fuel savings for JCB customers. This aligns perfectly with JCB’s wider engine strategy.”
