Independent exhaust gas heat system

摘要

An independent heat system for heating a motor vehicle passenger compartment comprises a surge tank feeding the heat transfer medium to a pump which circulates fluid through the cab heater core, heat exchanger and a waste heater core, if necessary. The heat exchanger is connected to an engine exhaust system for heating the circulating medium by the engine exhaust gasses. The heat system can be adapted for heating of a vehicle passenger compartment in any vehicle having no engine water cooling system.
