Abstract

The invention discloses a non-disassembly automobile three-way catalyst cleaning agent. The cleaning agent is prepared from a surface active agent, a macromolecular amine dispersing agent, a fuel oilfriction improver, an anti-rust agent, a solvent and a gasoline additive. Some functional poly-molecular compounds are combined with a cleaning agent and auxiliaries, by directly adding the raw materials into an oil tank, the whole oil way is cleaned, stubborn carbon deposition and oil sludge on gas inlet system prats are effectively dissolved, and the problems of air vent clog, power decrease, oil consumption increase and the like are solved; the tail gas exhaust rate is lowered, a three-way catalyst is protected, and the service life is prolonged; operation steps are reduced, and the matteris settled at one go.

Description

technical field [0001] The invention belongs to the technical field of automobile cleaning agents, and in particular relates to a cleaning agent for a three-way catalytic converter of an automobile without dismantling. Background technique [0002] Because fuel contains harmful substances such as sulfur and phosphorus, chemical complexes will be formed on the surface of the oxygen sensor and inside the three-way catalytic converter after combustion. In addition, due to the driver's bad driving habits or long-term driving on congested roads, the engine is often in a state of incomplete combustion, 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 ...
