Instantaneous neutralization and purification device for smoke and exhaust gas discharged from automobile

Abstract

Disclosed is an instantaneous neutralization and purification device for smoke and exhaust gas discharged from an automobile, which includes a first purification treatment device connected to an exhaust pipe, a connection pipe connected to the first purification treatment device, and a second purification treatment device connected to the connection pipe. The first purification treatment device includes a combustion system and a filtration system. A first pressure sensor detects an exhaust gas pressure greater than a threshold and signals a fuel tank to supply fuel to the combustion system for combustion and heating the filtration system to cause combustion of carbon build-up. A second pressure sensor detects the exhaust gas pressure becoming lower than a threshold and signals the fuel tank to stop supply of fuel. The exhaust gas is then conducted through the connection pipe, where an alkaline solution is sprayed to neutralize acids of the exhaust gas.

Description

(a) TECHNICAL FIELD OF THE INVENTION[0001]The present invention generally relates to a device that is capable of automatically removing carbon build-up formed in an exhaust gas filtration system that is mounted at a rear end of an automobile exhaust pipe to maintain smooth emission of exhaust gas of the automobile engine and to neutralize acidic exhaust gas and then fast reduce temperature for further cooperation with an exhaust gas purification unit to realize optimum purification of the exhaust gas.(b) DESCRIPTION OF THE PRIOR ART[0002]Both gasoline engine and diesel engine emit exhaust gas when it is put in operation. Severe emission of exhaust gas causes pollution of the atmosphere. Thus, it is a major issue of today to adopt whatever measures, in both technology and policy, to reduce the pollution caused by exhaust emission of diesel automobiles, in order to improve air quality. Although a gasoline engine does not generate such an obvious pollution as a diesel engine, the gasol...

AI Technical Summary

Benefits of technology

[0003]A primary objective of the present invention is to overcome the problem that in a conventional automobile engine that comprises an exhaust pipe to which a filtration system is mounted, operation temperature of the engine that is selectively raised to cause combustion and thus removal of carbon built on a filter core surface of the filtration system may not be properly increased due to travel environment and conditions of the automobile and the difference of individual driving practices, leading to incapability of combusting and removing the carbon build-up and leaving the carbon build-up in the filtration system to affect the smooth emission of exhaust gas and engine performance.

Problems solved by technology

Severe emission of exhaust gas causes pollution of the atmosphere.

Thus, it is a major issue of today to adopt whatever measures, in both technology and policy, to reduce the pollution caused by exhaust emission of diesel automobiles, in order to improve air quality.

Although a gasoline engine does not generate such an obvious pollution as a diesel engine, the gasoline engine still discharges toxicant substances, including hydrocarbons, which are also harmful to human body and the surroundings.
