Diesel pistons

Injection pressures of up to 2,200 bar, mean pressures of up to 31 bar, peak pressures of up to 210 bar, specific power output of up to 100 kW per liter, and ever lower exhaust gas emissions—these are the current requirements for modern passenger car diesel engines.

In order to overcome severe loads due to high temperatures and pressures, MAHLE has developed passenger car diesel pistons made of aluminum as well as diesel pistons made of steel.
