Design of cylinder and piston

The cylinder liner has a silicon carbide coating in electroplated nickel form and crossed smoothing with two diamond passes. Machining is carried out on machine tools with high-precision numerical control. Revised heat exchange surfaces support the structural design of the cylinder.

The ultra-compact 3-ring piston is made of a special aluminum alloy with high silicon content and low thermal expansion. There is a tin coating on the sliding surfaces. The piston is weight-reduced and reinforced.

Piston rings and area of application

The ring set includes a nitrided and chrome-plated steel I-ring, a special cast ring and a three-part wiper ring made of special chrome-plated steel alloy. The products are intended exclusively for racing in designated locations in accordance with the regulations of the relevant sports authorities. No liability is assumed for improper use.
