Abstract

The invention relates to a cleaning reducing agent for a three-way catalytic converter. The cleaning reducing agent comprises the following substances in percentage by weight: 3-5% of 2-octanone, 23-25% of ethylene glycol monobutyl ether, 13-16% of a 2- ethyl acetic acid, 29-32% of isopropyl alcohol, 5-7% of 1-laurylene, 2-4% of cyclohexane and the balance of water. Compared with a conventional product, the cleaning reducing agent for the three-way catalytic converter. is rapid in reactions, which sufficiently dissolves carbon deposition and sulfur phosphorus compounds, dredges the three-way catalytic converter, realizes the cleaning and the reducing of the three-way catalytic converter, restores the activity of the three-way catalytic converter, prolongs the service life of the three-way catalytic converter, effectively decreases the emission of carbon monoxide, hydrocarbon and nitric oxide, and achieves the purpose of reducing exhaust.

Description

technical field [0001] The invention belongs to the field of automobiles, and in particular relates to a three-way catalytic converter cleaning reducing agent. Background technique [0002] The three-way catalytic converter is the most important external purification device installed in the automobile exhaust system. It can remove CO, HC, and NO from automobile exhaust. x Harmful gases such as carbon dioxide, water and nitrogen are converted into harmless carbon dioxide, water and nitrogen through oxidation and reduction. When the high-temperature automobile exhaust gas passes through the purification device, the purification agent in the three-way catalytic converter will enhance CO, HC and NO x The activity of the three gases promotes a series of oxidation-reduction chemical reactions, in which CO is oxidized to colorless and non-toxic carbon dioxide gas at high temperature, and HC compounds are oxidized to water (H 2 O) and carbon dioxide, while NO x Then it is reduced...
