Figure 124
The piston (Fig. 123) 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. 124), and a "Tapered Face" intermediate ring (Fig. 124) , for superior
cylinder wall scraping. Piston cooling nozzles cool the piston and pin with engine oil supplied by the crankshaft main journals.
