This piston ring set is intended for the Citroën 2CV with a 425 cc engine and a piston diameter of 66 mm. The rings provide sealing between piston and cylinder wall. This supports compression in the combustion chamber and keeps oil consumption within limits. The set can be used during engine overhaul or maintenance. The design suits the thermal and mechanical load in the cylinder. Correct installation is important for proper fit and engine operation. The dimensions correspond to cylinders prepared for pistons with a diameter of 66 mm. The set forms part of the basic components of the engine’s moving assembly.
