Since 1998, the D12C380 water-cooled, six-cylinder in-line diesel engine has been manufactured. For a 1 liter (1000 cc) capacity, the engine’s power index is an astounding 31 horsepower.

One row of six cylinders makes up the D12C380. This makes maintenance and repairs easier. The cylinder liners are simple to replace, and the cylinder block and cylinder head are composed of ductile iron. Engine oil is double filtered using spin-on technology, and the air filter has interchangeable inserts.
