Abstract
The present invention relates to a cooling system for an internal combustion engine. The cooling system can be used in a hybrid electric vehicle. The system includes electric pumps in fluid communication with the engine and a control unit that governs the pumps. The pumps can be configured to supply fluid to either a cylinder block or cylinder head and backflow fluid through either the cylinder block or cylinder heads. Various arrangements of electrical and mechanical pumps are disclosed to control fluid flow and pressure.
