Abstract

Various systems are provided for liquid-cooling of an internal combustion engine. In one example, an internal combustion engine includes a cylinder head, a cylinder block coupled to the cylinder head, a first return line fluidically coupled to the cylinder head and to a coolant valve and including a heat exchanger configured to remove heat from coolant, a second return line fluidically coupled to the cylinder block and to the coolant valve, a bypass line branching off from the first return line and fluidically coupled to the coolant valve, and an originating supply line fluidically coupled to the cylinder head, the cylinder block, and the coolant valve, the originating supply line including a pump configured to supply coolant. The coolant valve is configured to control coolant flow through the coolant lines via rotational selection of one of a plurality of working positions.
