Audi piston sizes - Size charts

marka model piston sizes

Below is data on piston parameters for modifications of cars of different years of manufacture.

Main piston parameters:

Piston parameters include more than 15 sizes, the main ones are as follows:

Diameter: nominal piston diameter;
Height: piston height;
Compression height;
Groove height: first and second ring groove height;
Oil control ring groove height;
Cylinder gap: acceptable gap between cylinder and piston ring;
Piston pin diameter;
Ring height.

Note:

When piston is worn out, the gap between skirt and cylinder, piston upper groove erasing, skirt scoring, cracks and deformation of partitions between rings may occur.

Important: item parameters and sizes of different manufacturers can slightly differ.
