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...

Examples

[0062] The preparation method of the cleaning agent of the present invention is as follows: uniformly mixing organic acid, modified lignosulfonate calcium, surfactant, water, bentonite and cellulose at room temperature.

[0063] The cleaning method of the cleaning three-way catalytic converter of the cleaning agent of the present invention is not limited, and can be cleaned according to any of the following methods:

[0064] (1) Method 1: Connect the disassembled three-way catalytic converter to the outlet of the water pump, then fill the cleaning tank with cleaning agent, and turn on the ultrasonic generator and water pump for cleaning;

[0065] (2) Method 2: "Drip" cleaning, insert the infusion tube into the rubber intake vacuum tube of the engine, start the engine and input the cleaning agent, the cleaning agent is heated and evaporated to produce some water vapor, and the water vapor passes through the three-way catalytic converter to clean it;
