Description

Intake and exhaust system using Bernoulli principle for power output of internal combustion engine

The present invention relates to an intake / exhaust device using the Bernoulli principle to enhance the output of an internal combustion engine, and more specifically, to install the air vortex generator in the intake and exhaust sections of an internal combustion engine, such as a car, to rotate the intake and exhaust air. It is made of a vortex to improve the air flow and improve the combustion efficiency by improving the output according to the intake and exhaust efficiency so that the fuel efficiency is improved and the central inner tube entrance is large and the outlet is small, so the supercharge principle according to the Bernoulli principle is applied. It relates to an intake / exhaust device using the Bernoulli principle to increase the power of an internal combustion engine that reduces the smoke and extends the engine life.

Conventionally, a turbo charger and an intercooler are basically installed in a diesel engine to provide ease of high-speed driving by supercharging exhaust during high-speed driving, and to cope with exhaust gas regulation and CO2 regulation.

The turbocharger is like a blower, and uses the flow energy of the exhaust gas exiting the exhaust manifold of the engine.

Therefore, due to the flow energy of the exhaust gas, the turbine of the turbocharger rotates, and at the same time, the compressor installed coaxially opposite to the other side rotates, so that the exhaust is sucked and pressurized by this compressor and supercharged to the combustion chamber of the engine cylinder. Is supplied with.

At this time, in the case of the diesel engine equipped with only the turbocharger, the pressure of the intake air may be increased, but the problem of the temperature of the air rising in the process of compressing the air increases the combustion temperature and the exhaust temperature and substantially improves the filling efficiency. The degradation phenomenon is a problem.

Thus, by installing an intercooler in the exhaust line, the supercharged exhaust is cooled in the intercooler, the heat generation of the exhaust due to supercharging is blocked, and the cooled exhaust is supplied to the combustion chamber, thereby improving the filling efficiency of the combustion chamber.

As described above, the exhaust system of the diesel engine using the turbocharger and the intercooler increases the amount of exhaust air, thereby reducing exhaust gas and improving fuel efficiency, reducing engine noise, and improving fuel efficiency.

Despite these advantages, diesel engines using turbochargers and intercoolers have the following problems.

In order to improve combustion efficiency and pumping loss, a large amount of air is inhaled, and some of them are used for the pure combustion reaction. In this case, nitrogen containing about 80% of the atmosphere is indispensable. , It reacts with oxygen during the high temperature / high pressure combustion process to produce nitrogen oxide (Nox), which is the most problematic in diesel engines.

In order to improve the combustion conditions, a high-temperature and high-pressure combustion chamber atmosphere is required, but it is relatively easy to generate nitrogen oxides under these conditions, and thus there are limitations in improving fuel efficiency through improving combustion and reducing exhaust gas components such as smoke.

In addition, in the case of a diesel engine with a turbocharger and an intercooler, it is possible to improve the performance through a turbocharger system, but due to the characteristics of the turbocharger, it is impossible to improve exhaust characteristics for all areas, and inevitably in certain sections such as low speed and low load. The performance degradation phenomenon cannot be avoided.

In order to improve such characteristics, recently, a turbocharger is equipped with a waste gate valve to improve partial exhaust performance, but fundamental improvement is in a difficult state.

In addition, as shown in Patent No. 1754042, an air vortex generator is installed in a vehicle's intake and exhaust pipes to increase air intake and exhaust power through a vortex generator that induces air flow at high speed to extend its life.

However, the prior arts have a disadvantage in that the flow of air to be sucked and exhausted is not fast, and a flow separation phenomenon in which the wings and the wind are separated is generated because the vortex is generated and supplied in the left direction where the structure is complicated or the vortex is not smoothly generated. This flow separation phenomenon has the disadvantage that the air flow is irregularly generated to generate noise, causing loss in suction power, and vibration caused by this.

Therefore, the solution of the present invention was devised to solve such a conventional defect, flow separation due to the Bernoulli groove formed at regular intervals to the plane formed at the inlet of the wing installed on the intake and exhaust side of the vehicle to generate vortex It aims to reduce the phenomenon and improve the fuel efficiency by improving the combustion efficiency by smooth air flow, reducing smoke, reducing engine life and reducing noise.

Another object of the present invention is to provide a supercharger according to Bernoulli's principle by adjusting the size of the entrance and the entrance of the inner tube is small.

Another problem of the present invention is to form a slope at the tip of the Bernoulli wing, and to form a Bernoulli groove at the tip of the blade at regular intervals in the portion where the slope is formed to reduce flow separation and reduce the flow of air, resulting in a smooth air flow. It aims to improve fuel efficiency, reduce soot, and extend engine life and reduce noise.
