KOHLER® Tier 4 Emission-Compliant Diesel Engine Line

Kohler Engines, along with Lombardini, a Kohler Company, recently unveiled two new Tier 4 Final emission-compliant, heavy-duty diesel engines for the industrial, constructions and agricultural markets. The KOHLER® 1.9 l KDI1903TCR and the 2.5 l KDI2504TCR engines offer optimized fuel consumption, limited emissions, and remarkable performance without the use of a diesel particulate filter (DPF).

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.
