ABSTRACT:
A combined cooling and heating system for an internal combustion engine. The system includes a cooling jacket that cools the cylinder block and which discharges through a thermostatically controlled valve into a coolant sump having upper and lower outlets. The lower outlet discharges into a heating jacket for the induction system so as to provide induction system heating that is relatively independent of the engine speed. The upper sump outlet discharges into the cylinder head cooling jacket.
