Internal combustion engine having heat accumulator, control of heat supply system and control method of internal combustion engine

An internal combustion engine for a vehicle, comprising:

• a circulation passage that circulates a heat medium;
• an heat accumulator that accumulates heat;
• a heat supply device that supplies the circulation passage with heat accumulated by the heat accumulator through the heat medium;
• and
• a controller that starts to supply the circulation passage with heat by the heat supply device, at a timing set based on specific timing elements related to starting of the engine, and prior to the starting of the engine, wherein the heat supply timing by the heat supply device is set taking the timing at which a door opening/closing sensor that detects an open/close state of a door for getting in and out of the vehicle is opened as the timing element.
