Piston: Description and Operation

Pistons

A change in the production method from casting to forging enabled a weight saving of approx. 1.3 oz (37 g) to be obtained for each piston.







Piston rings

1. piston ring: adopted unchanged
2. piston ring: ring height reduced, angle changed, resulting in lower tangential forces
3. oil wiper ring: ring height reduced, only two-part (was three-part), lower tangential forces and therefore reduced cylinder wear
