Diesel engine Kohler KDI model 2504M

The KDI 2504M is a 4-stroke four-cylinder engine liquid-cooled. As with all Kohler KDI series motors, the basic features of this diesel engine are functionality and compactness. The demands of an increasingly demanding market in these terms have generated this generation of high performance engines in spite of the low levels of fuel consumption. Productivity is maximized and follows an effective emission containment strategy, in addition, management and maintenance are easy to apply. Due to its versatility, the KDI 2504M is used as an agricultural engine, for example for rotary hoes engine and motocultivator engine, or for generators engine, or also compressor and high pressure cleaner engine.
