Mahle Pistons
Mahle pistons have to put up with extreme pressures, as their working conditions have become significantly tougher in recent years. For example, thermal loads (with temperatures in the combustion chamber reaching 2,600ºC) and average ignition pressures have increased greatly. The inertial force loads have also increased due to high-speed concepts and a tendency to longer piston strokes. Naturally, the demands on pistons have also risen progressively: they must be lighter, must have lower oil consumption and must be absolutely safe—and this even under extreme conditions such as hot and cold load capacity testing and endurance testing under thermal shock.
