ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a supercharger for an internal combustion engine, more particularly a supercharger for an internal combustion engine of an automobile, that uses power taken from the camshaft of the engine and is simple in construction.
BACKGROUND OF THE INVENTION
Generally, an internal combustion engine for an automobile sucks the air needed for driving the engine by using the negative pressure generated when the engine is driven.
In order to increase the output of the engine, the amount of air provided to the engine should be increased. In order to make an automobile more powerful, a supercharger, which is like a turbocharger, is provided in the automobile. The supercharger increases the supply of air to the internal combustion engine of the automobile.
The supercharger supplies more air than the normal amount of air sucked by the engine using negative pressure. With the supercharger, the engine ignites more fuel with the increased amount of air, thus increasing the output of the engine.
The prior supercharger, like the turbocharger that is adopted in many kinds of automobiles, supplies air to the engine by using a turbine, that is operated by the exhaust gas of the engine.
However, the prior supercharger has many components and complicated construction. Therefore, the prior supercharger is expensive in its cost and heavy. The weight of the supercharge disadvantageously increases the weight of the automobile.
SUMMARY OF THE INVENTION
The object of the present invention is to provide a supercharger for an internal combustion engine of an automobile that is simple in its construction and is not heavy in its weight.
To achieve the above object, the present invention comprises a camshaft having an extended end protruded out of a cylinder block of the engine, a compressor mounted on the extended end of the camshaft, an air compressing chamber mounted around the compressor, a first supercharging line connecting the air compressing chamber to an air cleaner, and a second supercharging line connecting the air compressing chamber to a throttle valve body.
The supercharging line connected with the throttle valve body is connected to the portion of the throttle valve body where a valve for opening and closing the valve body is positioned.
The power taken from the camshaft drives the supercharger in accordance with the present invention. The construction of the supercharger can be simple and the number of parts used in the supercharger decreased.
Furthermore the weight of the supercharger can be reduced, because the number of parts used in the supercharger is decreased.
