This invention relates to a method of cooling an internal combustion engine, to an internal combustion engine assembly. The invention provides an internal combustion engine which has a primary and a secondary flow of coolant together with a method of cooling such and engine. The secondary flow of coolant is injected into the primary flow of coolant in dependence upon a variable provided by a sensor, which provides an indication of the temperature of the engine body in the region where the secondary flow of coolant mixes with the primary flow of coolant.

Internal combustion engine cooling system

A rotary valve provides single point flow control of coolant within the cooling system of an internal combustion engine. The valve distributes coolant flow from the engine in predetermined flow modes to either 1) the radiator and heater simultaneously, 2) a bypass circuit only, 3) the heater only, or 4) the radiator and bypass simultaneously. The single-point coolant control results in advantages of shorter warm-up times, a lower pressure drop (reducing power consumption by the pump), reduced engine emissions and fuel consumption, improved cabin heater performance, and improved engine durability due to reduced thermal shocks to the engine components by virtue of more precise control of engine operating temperature.
