Substitutive coolant temperature calculation device of internal combustion engine, equipped with additional heater

FIELD: engines and pumps.

SUBSTANCE: subject of the invention is a device (50) for calculating the engine coolant substitutive temperature (TEs) when an additional heater has been activated in advance to provide optimum control of the internal combustion engine. This temperature is based on weighing (Cp) between the measured temperature (TEmes) of the coolant and the oil temperature (TH). The coefficient of this weighing (Cp) varies depending on the activation conditions of the heater and it is determined based on a pre-compiled cartography. The calculated substitutive temperature takes into account the thermal state of the internal combustion engine.

EFFECT: improved engine start-up, eliminated problems of combustion, stops, fuel overexpenditures and increased emissions of pollutants.
