Description

Forced intake and cooling supply system of an internal combustion engine {system for forcibly compressing and cooling and supplying inlet air of internal combustion engine}

The present invention relates to an intake forced compression and cooling supply system of an internal combustion engine, and more particularly, to force intake of an internal combustion engine to forcibly compress, cool, and supply intake air (intake) supplied from an air cleaner to an intake manifold. A compression and cooling supply system.

In general, an internal combustion engine mixes fuel and air appropriately, introduces the mixed air into the cylinder of the engine, and obtains the required power by igniting the mixed air introduced into the engine by the ignition means. Use as main fuel.

The internal combustion engine generates power by purifying the air sucked from the air cleaner with a filter so that the injected fuel can be burned smoothly, and then naturally mixed with the injected fuel and injecting it into a vaporizer or an injector. Therefore, the output of the internal combustion engine is proportional to the engine speed and displacement and the pressure of the mixed gas. If the engine displacement and rotational speed are the same, the pressure of the mixed gas must be increased to improve the engine output, and the amount of intake air (intake) must be increased.

Conventional air intake increasing apparatuses include superchargers such as U.S. Patent Nos. 3877907, 4962642, Japanese Patent Laid-Open No. 58-13122, and Korean Utility Model Publication No. 85-1789. However, these superchargers are not able to forcibly inhale more atmospheric air into the cylinder other than the amount of air naturally inhaled at engine start, so a sudden increase in the output of the engine could not be expected.

Conventional engine output improving device using forced suction force has been developed a turbocharger using the rotational force of the rotary blades by the exhaust pressure, but this is a technology that uses the exhaust in nature, but at a low and medium speed, the output is reduced rather than high speed It is used only for driving.

On the other hand, there is a method of compressing natural air by using an electric motor, such as Korean Patent Publication No. 94-3524, 94-6055, etc., but they improve the output at low speed because the electric motor is installed by blocking the air holes of the air cleaner It may contribute to, but at a high speed there was a problem that the output of the engine is lowered.

The present invention has been conceived to solve the above problems, mainly intake air supplied from the air cleaner to the intake manifold intake by using a turbocharger employing a primary turbine and a secondary turbine, and cooler devices having a special structure It is an object of the present invention to provide an intake forced compression and cooling supply system of an internal combustion engine whose structure is improved to forcibly compress and supply air by cooling.
