Embodiment Construction

[0062] figure 1 The internal combustion engine according to the invention is shown schematically. The internal combustion engine comprises an internal combustion engine 10 which can be designed, for example, as a stroked piston internal combustion engine operating on the gasoline or diesel principle and comprising a cylinder housing 12 and a cylinder head 14 . Furthermore, the internal combustion engine has a regulating device 16 which has a first shut-off valve 18 , a second shut-off valve 20 and an actuator 22 . The first closing valve 18 can be moved by means of the actuator 22 , while the second closing valve 20 can be driven by the first closing valve 18 in a section of the possible overall movement of the first closing valve 18 .

[0063] The regulating device 16 is integrated in the cooling system of the internal combustion engine. Also integrated in the cooling system are the coolant channels 24 , 26 of the cylinder housing 12 and the cylinder head 14 , the heating s...

Abstract

The invention relates to an internal combustion engine with an internal combustion engine and a cooling system comprising a coolant pump, a main cooler (30), a radiator heat exchanger (28), bypassing the radiator heat exchanger (28) A bypass (34), a coolant passage in an internal combustion engine, and a regulating device having an actuator for controlled distribution of coolant according to at least one local coolant temperature, wherein the regulating device operates in one direction When controlling the actuator - in the first position (72) allows coolant to flow through the internal combustion engine and radiator heat exchanger (28) and prevents coolant from flowing through the bypass (34) and main cooler (30); - at In the second position (88), coolant is additionally allowed to flow through the bypass (34); and - in the third position (96), coolant is additionally allowed to flow through the main cooler (30), characterized in that the regulating device ( 16) Preventing coolant flow through the internal combustion engine (10) and allowing coolant flow through the radiator heat exchanger (28) in a zero position (58) before the first position (72).

Description

technical field [0001] The invention relates to an internal combustion engine and a motor vehicle with such an internal combustion engine. Background technique [0002] Internal combustion engines for motor vehicles usually have a cooling system in which coolant is pumped by means of one or more pumps in at least one cooling circuit and absorbs components integrated in the cooling circuit, in particular the internal combustion engine And the thermal energy of the oil cooler and / or the charge air cooler. The thermal energy is then discharged to the ambient air in the ambient heat exchanger, the so-called main (water) cooler and temporarily in the radiator heat exchanger, in the case of the radiator heat exchanger, to the facilities provided for conditioning the motor vehicle interior The air of the space is the ambient air. [0003] The cooling systems of modern motor vehicles have many more cooling circuits. For example, it is known to provide so-called major or main cool...
