ABSTRACT:
A mixture-drawing internal combustion engine comprises a cooling water circulation system, an intake conduit and an automatically controlled heating device in heat exchange contact with the intake conduit. The heating device receives cooling water from the cooling water circulation system and exhaust gases from the internal combustion engine. A shutoff device controls the flow of the cooling water through the heating device. The shutoff device remains closed until a predetermined cooling water temperature is reached. When the predetermined cooling water temperature is reached, the shutoff device opens increasingly as the temperature of the cooling water rises.
