Description

System for purifying blow-by gas & for automatically injecting cleaning solution of internal combustion engine

The present invention relates to the purification of blow-by gas of the internal combustion engine and the automatic injection system of the assistant cleaning agent, and more particularly, to the blow-in gas generated during operation of the engine and concentrated in the valve chamber of the engine to the intake manifold side. The present invention relates to a system for purifying blow-by gas of an internal combustion engine and an automatic spraying system of the supporting detergent, which can simultaneously return and automatically spray the supporting detergent.

In general, internal combustion engines such as gasoline engines, LPG engines, alcohol engines, hydrogen engines, fuel injection or electric ignition engines and diesel engines with or without carburettors emit exhaust gases that are harmful to the human body.

The exhaust gas of the internal combustion engine is classified into three types according to the emission source: blow-by gas discharged from the crankcase (upper valve chamber) of the engine, boil-off gas discharged from the fuel tank or carburetor, and exhaust gas discharged from the exhaust pipe. .

The blow-by gas is also called crankcase emission, and is a gas that escapes from the crankcase, especially the upper part of the valve chamber, at a gap between the combustion chamber cylinder and the piston of the engine, and a substantial part of the fuel is HC. The remaining components include combustion gases and partially oxidized mixed gases. If the blow-by gas stays inside the crankcase, the engine is corroded, leading to oil degradation. Therefore, the inside of the crankcase is sufficiently ventilated, and the blow-by gas is discharged to the atmosphere or returned to the intake manifold or air hose for reburn. However, in the latter case, a vicious cycle is repeated such that a large amount of engine oil or impurities are introduced together with blow-by gas, causing incomplete combustion and soot. In addition, this phenomenon becomes more serious when the engine is aged or when the engine runs at high speed. In blow-by gas, since the ratio of hydrocarbon (HC) which is harmful to a human body is large, the situation which mandates the apparatus which re-burns hydrocarbon and releases it to the atmosphere is also required.

The present invention is conceived to solve the above problems, the engine oil and impurities contained in the blow-by gas in the process of returning the blow-by gas concentrated in the valve chamber cover of the upper part of the engine to the intake manifold or air hose side Is completely removed by filtering, and the supporting agent is naturally injected into the intake manifold in the vapor state by using the rising pressure and the air suction pressure inside the engine to completely decompose the supporting agent by the latent heat generated by the combustion of fuel. Internal combustion engine with improved structure to remove impurities such as carbon stuck inside the cylinder by complete combustion and to improve combustion efficiency by cooling latent heat itself when the crude detergent injected into the vapor state is completely decomposed by latent heat. Blow By Gas Purification & Supporting Detergent Chair The purpose is to provide a copper injection system.

Referring to the operation of the automatic injection system of the purification of the blow-by-gas and the assistant cleaning agent of the internal combustion engine according to a preferred embodiment of the present invention configured as described above are as follows.

First, when the fuel gas mixed with air and fuel supplied from the intake manifold 12 is ignited at about 500 to 550 ° C. in the engine combustion chamber 10 to lower the cylinder (not shown) inside the combustion chamber 10. The exhaust gas is discharged through an exhaust manifold (not shown), and blow-by gas is concentrated in the upper valve chamber cover 14 of the combustion chamber 10. The blow-by gas is discharged through the first and second cover ports 13 and 15 together with the engine oil and impurities and flows into the filter member 30 via the return path 20.

It can be gradually removed by combustion to prevent environmental pollution.

Secondly, in the return process of the blow-by gas, by supplying a small amount of the supporting detergent in the engine room in the steam state, the supporting agent is completely decomposed by the latent heat generated by the combustion of the fuel to improve the combustion efficiency, It helps to increase the combustion efficiency of the engine by cooling the latent heat itself when the crude detergent injected in the steam is completely decomposed by latent heat.

Third, by supplying the air of the air cleaner to the return path by the clean path, it is possible to prevent inefficiency due to incomplete combustion.

Fourth, by installing a magnetic device in the filter member can exhibit the effect of blocking the electromagnetic waves.
