Kohler Engines, along with Italy-based Lombardini, a Kohler Company, have unveiled two new Tier 4 Final emission-compliant, heavy-duty diesel engines for the industrial, construction and agricultural markets. The Kohler 1.9 Liter KDI1903TCR and the 2.5 Liter KDI2504TCR engines offer optimized fuel consumption, limited emissions, and enhanced performance without the use of a diesel particulate filter (DPF).
“Kohler is expanding its power range offering with some very innovative solutions,” said Dick Fotsch, president of Kohler Global Power Group. “The power and torque of these engines in relation to their compact sizes and reduced fuel consumption have clear advantages to construction, industrial and agricultural equipment manufactures and end-users.”
Simple Tier 4 final emission compliance
Achieving Tier 4 Final emission compliance without a DPF was possible through the efficient use of the engine’s components, including Kohler’s direct injection system, cooled exhaust gas recirculation (EGR) and diesel oxygenated catalyst (DOC). The high-pressure common rail system (CSR) utilizes pressures at 2000 bar (29,000 PSI) resulting in better atomization of the fuel, improved fuel consumption and a reduction in emission particulates. The CSR, combined with the fuel mapping program and other systems, makes for improved exhaust emissions and Tier 4 Final compliance.
Cost savings
The same technology that makes the Kohler KDI diesel engines Tier 4 Final emission compliant is also what makes the engines a money-saving alternative for original equipment manufacturers and owners. The compact size of Kohler’s new diesel engines offers increased compatibility and will fit existing and new equipment designed by manufacturers. Also, the direct injection system offers equipment owners the ability to save up to $1,400 on fuel and $116 on oil per year—when compared to indirect injection diesel engines with diesel particulate filters and based on 1,000 hours of annual operation at $3.75/gallon of diesel fuel and $4.10/quart of oil (according to Kohler).
