Abstract

The invention relates to a three-way catalytic converter cleaning reducing agent, which is composed of the following substances in weight percentage: 3-5% of sec-octyl ketone, 23-25% of ethylene glycol butyl ether, 13-16% of 2-ethyl acetic acid, Isopropanol 29‑32%, 1‑Dodecene 5‑7%, Cyclohexane 2‑4%, water balance. Compared with the existing products, the three-way catalytic converter cleaning reducing agent of the present invention has rapid reaction, can fully dissolve carbon deposits and sulfur and phosphorus compounds, dredge the three-way catalytic converter, realize cleaning and reduction of the three-way catalytic converter, and restore the three-way catalytic converter Active, prolong the service life of the three-way catalytic converter, effectively reduce the emissions of carbon monoxide, hydrocarbons, and nitrogen monoxide, and achieve the purpose of reducing exhaust emissions.

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...
