Diesel engine Kohler KDI model 1903TCR

The KDI 1903 TCR engine is the common rail version of the Kohler KDI 1903M diesel engine. In a market that requires more and more compact, powerful and fuel-efficient engines, maintaining high performance in terms of productivity and efficiency while not keeping up with the ability to contain emissions and at the same time manageable, this innovative diesel engine represents the most functional and innovative response. The KDI 1903 TCR is a highly versatile 3-cylinder liquid-cooled engine. It is widely used as an agricultural engine (engine for rotary hoes and motocultivator), as well as as a compressor, generator and high pressure cleaner engine.
