| Two-stroke pistons
These pistons are mainly used in gasoline and diesel engines for passenger cars under heavy load conditions. They have cast-in steel strips but are not slotted. As a result, they form a uniform body with extreme strength. |
| Cast solid skirt pistons
Piston top, ring belt and skirt form a robust unit. Cast solid skirt pistons have a long service life and can be used in gasoline and diesel engines. Their range of applications extends from model engines to large power units. |
| Forged solid skirt pistons
This type of piston can mainly be found in high performance series production and racing engines. Due to the manufacturing process, they are stronger and therefore allow reduced wall cross-sections and lower piston weight. |
| AUTOTHERMIK®- / HYDROTHERMIK® pistons
These very quiet running pistons are used primarily in passenger cars. The pistons have cast-in steel strips and are slotted at the transition from ring belt to skirt section. |
| AUTOTHERMATIK®- / HYDROTHERMATIK® pistons
These pistons are used mainly in gasoline and diesel engines for passenger cars under heavy load conditions. They have cast-in steel strips but are not slotted. As a result, they form a uniform body with extreme strength. |
| ECOFORM® pistons with pivoting side cores
Weight optimized pistons for passenger car gasoline engines. As a result of a special casting technology these pistons offer low weight and high structural rigidity. |
| Ring carrier pistons with pin boss bushes
These pistons for diesel engines have a ring carrier made from special cast iron that is connected metallically and rigidly with the piston material in order to make it more wear resistant, in particular in the first groove. With pin boss bushes made from a special material, the load-bearing capacity of the pin boss is increased. |
| Ring carrier pistons with cooling channel
Ring carrier pistons with cooling channel are used in conditions with particularly high operating temperatures. Because of the high temperatures at the piston top and the ring belt, intensive cooling is provided with oil circulating through the cooling channel. |
| Ring carrier pistons with cooling channel and crown reinforcement
These pistons are used in diesel engines under heavy load conditions. For additional protection and to avoid cavity edge or crown fissures, these pistons have a special hard anodized layer (HA layer) on the crown.
|
| Pistons with cooled ring carriers
For these pistons, ring carriers and cooling channels are combined into one system in a special production process. This provides the pistons with significantly improved heat removal properties, especially in the first ring groove. |
| FERROTHERM® pistons
A steel piston top and an aluminum piston skirt that are flexibly connected via the gudgeon pin. Due to their high strength and lower wear values, these pistons make it possible to comply with low exhaust and emission standards, especially for diesel engines under heavy loads. |
