The inner liner has a silicon carbide coating on a galvanic nickel matrix. Cross-smoothing in two diamond steps and processing on high-precision CNC machines enable tight tolerances to be maintained. Newly calculated, extra-large heat exchange surfaces support the temperature transition.\u003c\/p\u003e\u003ch3\u003ePistons and piston rings\u003c\/h3\u003e\u003cp\u003eThe super-compact piston with three segments is made from a special aluminum-silicon alloy with low thermal expansion. The addition of tin on the sliding surfaces, CNC machining as well as the reduced weight and reinforced construction characterize its design.
