Reciprocating engine

Abstract:

A reciprocating engine includes a crankshaft and a connecting rod rotatably coupled to the crankshaft. The connecting rod defines a fluid passage extending along a length thereof. The reciprocating engine also includes a piston dome coupled to the connecting rod, the piston dome defining an inlet in fluid communication with the fluid passage of the connecting rod for receiving a fluid from the fluid passage of the connecting rod, a cooling passage in fluid communication with the inlet for circulating the fluid through the piston dome, and an exit in fluid communication with the cooling passage.
