Three-way catalytic converter carbon deposit cleaning agent specially used for naturally aspirated engine

Abstract

The invention provides a three-way catalytic converter carbon deposit cleaning agent specially used for a naturally aspirated engine, belonging to the technical field of engine cleaning agents. According to the three-way catalytic converter carbon deposit cleaning agent specially used for the naturally aspirated engine provided by the invention, the carbon deposit cleaning agent comprises the following raw materials in parts by weight: 10-30 parts of organic acid, 0.1-1 part of modified calcium lignosulphonate, 1-8 parts of a surfactant, 70-100 parts of water, 5-15 parts of bentonite and 0.1-1 part of cellulose; the preparation method of the cleaning agent provided by the invention comprises the step of mixing the organic acid, the modified calcium lignosulphonate, the surfactant, the water, the bentonite and the cellulose uniformly at room temperature; the cleaning agent provided by the invention can thoroughly clear carbon deposit impurities on a three-way catalytic converter, clears difficult-to-clean places such as corners and concave portions of a three-way catalytic converter specially used for the naturally aspirated engine particularly effectively, and can prevent the engine from being corroded.

Description

technical field [0001] The invention relates to a three-way catalytic converter carbon deposit cleaning agent specially used for naturally aspirated engines, and belongs to the technical field of engine cleaning agents. Background technique [0002] Today's engines can be divided into naturally aspirated and in-cylinder direct injection; naturally aspirated is a form in which atmospheric pressure presses air into the combustion chamber without passing through any supercharger, which means that the air is simply filtered through the air. Cleaner - throttle (commonly known as "throttle") - intake manifold - to the "cylinder", gasoline is directly injected into the intake manifold through the fuel injector. [0003] The three-way catalytic converter is the most important external purification device installed in the automobile exhaust system. When the high-temperature automobile exhaust passes through the purification device, the purification agent in the three-way catalytic co...

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 poisoning of the oxygen sensor and the three-way catalytic converter fails, the three-way catalytic converter is blocked, and the engine does not work normally, resulting in problems such as increased fuel consumption, decreased power, and excessive exhaust gas.
