Piston: Description and Operation
DESCRIPTION
PISTONS
The piston (Fig. 87) is constructed of aluminum and is gravity cast, free floating design. The piston incorporates a centrally located high swirl
combustion bowl, and utilizes a "keystone" style top compression ring (Fig. 88), and a "Tapered Face" intermediate ring (Fig. 88), for superior
cylinder wall scraping. Piston cooling nozzles cool the piston and pin with engine oil supplied by the crankshaft main journals. High horsepower
pistons are gallery cooled and utilize jet piston cooling nozzles.
