ABSTRACT:
An engine warming-up apparatus includes a reserve tank integrally provided with a heat insulating device provided in a coolant circuit in which coolant for cooling an internal combustion engine flows. The reserve tank includes a reserve tank body secured to the top of a tank base, a connection pipe for connecting between an outlet pipe of the tank base and the inside of the reserve tank body, and a heat insulating device located-between the tank base and the reserve tank body and covered by the reserve tank body. A degassing pipe is provided at the top of the heat insulating device so as to communicate between the inside of the heat insulating device and the inside of the reserve tank body. A water filling opening of a hot water supply pipe is formed around the top of the inside space of the heat insulating device. In this way, a high temperature coolant is firstly supplied at a cold start, thereby improving warming up performance.
