  • System and method for cooling engine pistons
    Patent number: 9284876
    Abstract: An engine cooling system and method for operating the engine cooling system is disclosed. In one example, engine oil is sprayed on to a piston via piston cooling jets. The approach judges whether or not to operate the piston cooling jets based on a benefit assessment. The approaches may be suitable for systems that include a variable oil pump.
