Kohler diesel engines bypass DPF solution

Updated Feb 19, 2013

Kohler and sister engine brand Lombardini developed a new family of Tier 4 Final emissions-compliant power solutions that avoid the use of particulate filters.

In advance of the various 2013 worldwide emissions requirements, the result will be industrial, agricultural, landscaping or even smaller construction equipment powered by a compact engine built without the additional bulk required for a diesel particulate filter (DPF), Kohler and Lombardini officials say. The engines will fit existing machine design envelopes.

In the North America-based Kohler nomenclature, the new 1.9-liter KDI1903TCR and 2.5-liter KDI2504TCR engines will boast 166 and 221 foot-pounds of torque at 1,500 rpm. The engine mapping program within the electronic control unit (ECU) will monitor and manage output in varying conditions, by injecting fuel into the combustion cycle to maximize torque and power when needed.

The new Kohler and Lombardini engines were developed and will be built at the Lombardini plant in Reggio Emilia, Italy. During the Oct. 25 press conference at the facility, broadcast live to a worldwide online audience, Lombardini officials further announced the Tier 4 Final solution will eventually expand the engine product line to a 3.4-liter model, rated at 100 kilowatts or 134 horsepower.
