Internal combustion engine including heat accumulation system, and heat carrier supply control system

摘要

Disclosed is a technology capable of efficiently supplying a heater core 12 or a heat accumulation system 15 or an internal combustion engine body 1 with cooling water heated by a cooling water heating mechanism 20 by restraining an unnecessary heat radiation from the cooling water in an internal combustion engine including the heat accumulation system. The internal combustion engine including the heat accumulation system has a first heat carrier circulation route on which the heat carrier circulates through the cooling water heating mechanism 20 and the heater core 12 without via the internal combustion engine body 1 , a second heat carrier circulation route on which the heat carrier circulates through the cooling water heating mechanism 20 and the heat accumulation system 15 without via the internal combustion engine body 1 , and a heat carrier circulation route on which the heat carrier circulates through the heat accumulation system 15 and the internal combustion engine body 1 , and is capable of properly selecting these routes.
