.The piston has 2 additional CNC-milled oil grooves in the piston skirt, in which engine oil collects to improve the lubrication at the cylinder bore and the properties in emergency running. Especially for the sensitive running-in phase of the cylinder, the piston was provided with an extra molybdenum coating. Through 2 oil holes and 1 groove in each of the bearing points of the piston pin, this itself is better lubricated.
