ABSTRACT:
A piston for a high performance engine has a crown and a skirt integrally formed with the crown. A step is defined about the crown and an annular channel is machined in the step. A ring belt facially encircling the crown sealingly covers the annular channel so as to form an enclosed passageway where the coolant circulates. The piston has passages by which coolant under pressure is sent to the crown. The crown has a coolant entry duct communicating the passages to the annular channel and has a coolant exit duct communicating the annular channel with a cavity in the skirt.
