Problems solved by technology

In addition, due to the driver's bad driving habits or long-term driving on congested roads, the engine is often in an incomplete combustion state, which will form carbon deposits in the oxygen sensor and three-way catalytic converter
It is precisely because of many factors that the oxygen sensor and the three-way catalytic converter are poisoned and failed, the three-way catalytic converter is blocked, and the EGR valve is blocked by deposits and other faults, which cause the engine to work abnormally, resulting in increased fuel consumption, power decline, and exhaust gas exceeding the standard, etc. question

Abstract

The invention relates to a cleaning agent for an automobile three-way catalyst. The cleaning agent is prepared from the following raw materials in parts by weight: 10-20 parts of sulfosalicylic acid,10-15 parts of a composite surfactant, 1-5 parts of a builder, 1-5 parts of a composite corrosion inhibitor, 0.5-1 part of a chelating agent and 60-90 parts of deionized water. Glue and carbon depositof the oil nozzle can be effectively cleaned and dredged, cleanliness of a fuel oil system is guaranteed, fuel oil is saved, and therefore the oxygen sensor and the three-way catalytic conversion device are effectively protected, carbon deposit of the valve seat can be eliminated, the valve and the valve guide pipe can be lubricated, sealing is improved, and power is improved.

Description

technical field [0001] The invention relates to the technical field of pollution treatment, in particular to a cleaning agent for an automobile three-way catalytic converter. Background technique [0002] The three-way catalytic converter is the most important external purification device installed in the automobile exhaust system. It can convert harmful gases such as CO, HC and NOx emitted from automobile exhaust into harmless carbon dioxide, water and nitrogen. When the high-temperature automobile exhaust gas passes through the purification device, the purification agent in the three-way catalytic converter will enhance the activity of the three gases CO, HC and NOx, and promote them to undergo a certain oxidation-reduction chemical reaction, in which CO is oxidized at high temperature to become non-toxic. Color, non-toxic carbon dioxide gas; HC compounds are oxidized to water and carbon dioxide at high temperature; NOx is reduced to nitrogen and oxygen. Three kinds of h...
