An engine rapid warm-up system includes cooling water circulating through an engine 1, a radiator 2 introducing the cooling water to be cooled, a heat accumulator 3 storing the cooling water heated by the engine 1, and a pipe 6 and a water pump 7 that circulate the cooling water through the engine 1, the radiator 2 and the heat accumulator 3. In the system, high temperature cooling water that is stored in the heat accumulator 3 is controlled to be sent to and warm up the engine 1 at engine start, heat of exhaust gas is controlled to recover so that the cooling water obtained after heat recovery is circulated through and warms up the engine 1.
