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.

preparation example Construction

[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;

[0066] (3) Method 3: Disas...

Abstract

The invention provides a special three-way catalytic converter carbon deposit cleaning agent for naturally aspirated engines, which belongs to the technical field of engine cleaning agents; the invention provides a special three-way catalytic converter carbon deposit cleaning agent for naturally aspirated engines. In parts by weight, the carbon deposit cleaning agent includes the following raw materials: 10-30 parts of organic acid, 0.1-1 part of modified calcium lignosulfonate, 1-8 parts of surfactant, 70-100 parts of water, and 5-15 parts of bentonite , 0.1 to 1 part of cellulose; the preparation method of the cleaning agent of the present invention is: organic acid, modified calcium lignosulfonate, surfactant, water, bentonite, and cellulose are mixed uniformly at room temperature; the cleaning agent of the present invention The agent can thoroughly remove carbon deposits and impurities on the three-way catalytic converter, especially effectively remove corners and recesses of the three-way catalytic converter dedicated to naturally aspirated engines, which are difficult to clean, 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...
