IC engine cooling and vehicle heating circuits

摘要

The cooling medium circuit has an engine cooling circuit and a heating circuit. The heating circuit is designed to be independent of the cooling circuit. The heating circuit has an electric pump (10) which is speed or cycle controlled and switched on and off via an electronic control device regulating the heat output. The system has a feed (9) and return (12) supply integrated into a common connection (13) located directly to the engine block (1).
