(1) FCD Pistons

Our high-speed diesel engines were the first to incorporate ductile cast iron FCD pistons. The material is not only stronger, but also offers greater durability and resistance to high temperatures than do ordinary aluminum pistons.

(2) Cylinder Liners

To increase the wear resistance of cylinder liners, we have developed a Tufftride treatment that, in addition to our special honing method, increases lubricity and significantly enhances surface durability.

(3) Roller Tappets

Roller tappet system increases durability by reducing friction between tappets and cams; this is the first class of engine to employ them. The roller tappet system has higher reliability compared to conventional tappet & cam type.
