Abstract
An engine assembly includes an engine block that defines a cylinder bore. A reciprocating piston is disposed in the cylinder bore, and has a first side and a second side. The first side cooperates with the engine block to partially define a combustion chamber, and the second side is opposite the first side. A piston squirter is disposed adjacent to the second side of the piston and configured to expel a received flow of engine oil onto the piston. A thermal fluid valve is disposed in fluid communication with the piston squirter and is configured to selectively restrict the flow of engine oil to the piston squirter in response to a temperature of the engine oil.
