ジン過冷却防止配管装置。 The cooling water in the engine is switched between the circulation pipe and the return pipe to the cooling water tank via a temperature control valve, and the temperature of the engine cooling water is adjusted to prevent the engine from cooling too hot. In the cooling water piping system, the cooling water tank side is designed to send cooling water at the minimum pressure required to send water to the suction side of the engine-side cooling water pump to the suction port of the engine-side cooling water pump. 1. A piping device for preventing engine supercooling, characterized in that a separate cooling water pump is connected to the engine so that the pressure of the cooling water in the engine is controlled by the water head loss in the piping after the engine.
