り提案されている。For the output direction of the internal combustion engine, a supercharging device, a so-called supercharger, is selectively connected to the output shaft of the internal combustion engine by an electromagnetic clutch, and is driven by the shaft output of the internal combustion engine. It has been proposed in the past to incorporate it into the intake system.

案されている。When a spark ignition internal combustion engine is supercharged by a supercharging device, its output performance is improved, but knocking is more likely to occur as the compression ratio increases and the combustion chamber wall temperature increases. For this reason, in spark-ignition internal combustion engines equipped with a supercharging device, when the supercharging device performs supercharging operation in order to suppress the occurrence of knocking, an intake air coolant such as water or alcohol is supplied to the intake passage. However, an internal combustion engine equipped with an intake air coolant supply system for cooling intake air has already been proposed in U.S. Pat.

内燃機関はノッキングを激しく発生Ｊ−るようになる。When an intake air coolant such as water or alcohol is supplied to the intake passage, the intake air is cooled and spark ignition internal combustion engines are less prone to knocking, but in vehicles such as automobiles,
Generally, intake coolant is supplied from the intake coolant tank mounted on the vehicle, and even though the intake coolant in the 1cm intake coolant tank is used up, the intake coolant is still supplied to the intake coolant tank. If the fluid is not replenished and there is a shortage of intake cold W fluid in the intake coolant tank, it is possible that the intake coolant cannot be supplied to the intake passage.
At this time, if the supercharging device performs supercharging in the same way as when the intake air coolant is being supplied to the intake passage, the spark ignition internal combustion engine will cause severe knocking.

の運転制御方法を捉供１′ることを目的としている。In view of the above-mentioned problems, the present invention provides an operation of a supercharging device for an internal combustion engine that controls the operation of a supercharging device in connection with the supply of intake air coolant to an intake passage, and performs supercharging without causing knocking. The purpose is to provide a control method.

過給装置の運転制御方法によって達成される。According to the present invention, the intake coolant stored in the intake coolant tank is used in an internal combustion engine to be supplied to the intake passage, and the internal combustion engine is selectively drive-coupled to the output shaft of the internal combustion engine by an electromagnetic clutch. ? In the operation control method of a supercharger driven by the shaft output of Section 31, when the remaining m of intake air coolant in the intake air coolant tank is below a predetermined value, the electromagnetic clutch is activated over the entire operating range of the internal combustion engine. This is achieved by a method for controlling the operation of a supercharging device for an internal combustion engine, characterized in that the operation of the supercharging device is stopped by releasing the supercharging device.

燃機関の過給に伴うノッキングの発生が抑制される。According to the operation control method of a supercharging device for an internal combustion engine according to the present invention, when the intake air coolant in the intake air coolant tank is consumed and the intake air coolant cannot be supplied to the intake passage, the supercharging device operates WJ+. By stopping the engine over the entire operating range of the internal combustion engine, it is avoided that the supercharging system is activated and supercharging is performed even though intake air coolant is not being supplied to the intake passage. This suppresses the occurrence of knocking associated with supercharging on the internal combustion side, particularly in spark ignition internal combustion engines.
