Abstract:
A method for controlling variable oil pressure to a piston squirter based on piston temperature according to an exemplary embodiment includes a temperature estimation module and an oil pump pressure control module. The temperature estimation module estimates a piston temperature associated with a cylinder based on engine operating conditions. The oil pump pressure control module controls the oil pressure level delivered to at least one of piston squirter associated with the cylinder to selectively spray oil on the piston based on temperature estimations.
