Piston: Description and Operation
Aluminum pistons are used after selecting the grade that meets the cylinder bore diameter. Each piston has two compression rings and one oil ring. The
piston pin made of chromium steel is offset 1 mm toward the thrust side, and the thrust pressure of piston to the cylinder wall varies gradually as the
piston travels.
