Machining is carried out on machine tools with high-precision numerical control. There is a clearance of 0.05 mm between the cylinder and piston. Newly calculated and improved heat exchange surfaces complement the design.

Pistons and piston rings

The ultra-compact, lightweight and reinforced piston has three rings. It is made from a special aluminum alloy with a high silicon content and low thermal expansion. The sliding surfaces are coated with tin; The piston is also machined on numerically controlled machine tools.

• First ring: compression ring made of nitrided and chrome-plated steel
• Second ring: special cast iron
• Wiper ring: three-piece design made of special chrome-plated steel alloy
