and the exhaust port (58) are short-circuited by a bypass pipe (62) provided with a relief valve (61).

速回転する過給機（５４）をもって、多量の空気を圧縮
して、放熱器（５９）で冷却した後、エンジン（５１）
に給気することにより、エンジン（５１）の出力の増大
を図っている。This device has a supercharger (54) that rotates at high speed using the exhaust gas of a gasoline engine (51), compresses a large amount of air, cools it with a radiator (59), and then returns the air to the engine (51).
By supplying air to the engine (51), the output of the engine (51) is increased.
また放熱器（５９）は、圧縮された空気の温度を下げて
、給気量を増やすとともに、燃焼温度を下げ、異常燃焼
を起こしたり、熱負荷が過大となったりするのを抑制し
ている。In addition, the radiator (59) lowers the temperature of the compressed air, increases the amount of air supply, and lowers the combustion temperature to prevent abnormal combustion and excessive heat load. .
しかし、上述の装にでは、エンジンの高速、島負荷運転
時において、給気のＣ度を十分に低下させるには、低速
似負荷運転時には不必要なほどの容量の大きい放熱器が
必要となり、車両搭載上に不都合を与えるのみならず、
低速低負荷転時の性能を阻害する。However, with the above-mentioned equipment, in order to sufficiently reduce the C degree of the intake air when the engine is operating at high speed and under load, a radiator with a large capacity that is unnecessary during low speed and similar load operation is required. This not only causes inconvenience when mounted on a vehicle, but also
It impedes performance during low speed and low load operation.
一方、放熱器の容量を小さく抑えた場合には、エンジン

気の過大な温度上昇を防止して、上述の問題点の解決を
図っている。On the other hand, if the capacity of the radiator is kept small, when the engine (51) rotates at high speed, ! Since the I￥ pressure rises above a predetermined value, a relief valve (61) is installed in the exhaust system and automatically opens to bypass the exhaust gas, thereby keeping the rotation speed of the supercharger (54) constant. In order to solve the above-mentioned problems, the temperature of the compressed air is kept below the above-mentioned temperature, thereby preventing an excessive rise in the temperature of the compressed air.
このため、エンジン（５１）の高速回転時における出力
の増大が制限されている。For this reason, an increase in output when the engine (51) rotates at high speed is restricted.

の諸問題を解決しようとするものである。Means for Solving Problem C] The present invention uses a radiator to cool the air that has become high temperature due to adiabatic compression in the supercharger, and also uses a radiator to cool the air that has become high temperature due to adiabatic compression in the supercharger. In this case, by injecting water or alcohol into the air supply and cooling it using the latent heat of vaporization, the temperature of the air supply to the engine can be maintained at an optimum level, and the radiator can be made smaller. This is an attempt to solve the problems mentioned above.

6 In addition, water or alcohol only needs to be injected when it is necessary to greatly lower the supply air temperature, such as when increasing the temperature of the air, such as when increasing the temperature of the supply air. It can be controlled to the optimum value. Moreover, this makes it possible to reduce the amount of NOx and soot (exhaust black smoke) in the exhaust gas.
