Abstract

An internal combustion machine includes a combustion engine and a cooling system with a coolant pump, a main cooler, a heating heat exchanger, a bypass bypassing the heating heat exchanger, coolant channels, and a regulating device with an actuator for distributing a coolant depending on at least one local coolant temperature. When the actuator is actuated in a given direction, the regulating device allows a coolant flow through the combustion engine and the heating heat exchanger and prevents a coolant flow through the bypass and the main cooler in a first position; additionally allows a coolant flow through the bypass in a second position; and additionally allows a coolant flow through the main cooler in a third position. In a zero position which lies before the first position, the regulating device prevents a coolant flow through the combustion engine and allows a coolant flow through the heating heat exchanger.
