Achieving Tier 4 Final emission compliance without a DPF was possible through the efficient use of the engine’s components, including Kohler’s exclusive direct injection system, cooled exhaust gas recirculation(EGR) and diesel oxygenated catalyst(DOC)
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.
Other features of the new diesel engines include less noise and vibration making it Kohler’s quietest diesel model, as well as a heavy-duty crankcase for increased durability to extend the life of the engine.
