Internal combustion engine in which oil is used for lubrication and cooling, especially where the oil cooling represents the only cooling system of the internal combustion engine

摘要

The invention relates to an internal combustion engine (1) in which oil is used for cooling and lubrication, especially where the oil cooling represents the only cooling system. In order to achieve a rapid warming of the oil inside the heat exchanger, the bypass line (9), controlled by a thermostat (8), is led through the heat exchanger (12) and releases a proportion of the heat to the oil present therein. At the same time the outer coolant feed line (13) to the heat exchanger remains closed by a coolant thermostat (14) in order to accelerate the warming-up of the heat exchanger contents. The two thermostats (8) and (14) are operatively connected to one another and are both infinitely adjustable as a function of the temperature so that the thermostat (14) releases the coolant supply as soon as the thermostat (8) switches the oil circulation from the bypass line to the heat exchanger (Fig.1).
