Cleaning agent for throttle valve and preparation method for cleaning agent

Abstract

The invention discloses a cleaning agent for a throttle valve and a preparation method for the cleaning agent. The cleaning agent for the throttle valve comprises the following components in percentage by mass: 60 to 80 percent of non-aryl alkane of C8-C13, 3 to 6 percent of polar solvent, 3 to 6 percent of synthetic base oil, 1 to 3 percent of antiwear agent, 1 to 2 percent of metal protective agent, 0.04 to 0.08 percent of macromolecule detergent dispersant, 10 to 14 percent of deodorized liquefied petroleum gas and 2 to 3 percent of carbon dioxide. The cleaning agent has the cleaning function of the traditional carburetor cleaning agent, also has a lubricating effect on the throttle valve and a protective effect on a special coating of the inner cavity of an electronic throttle valve, and does not have corrosion or swelling effects on rubber oil seal on an idle-speed motor. The cleaning agent can eliminate oil sludge, dust and carbon deposit which are adhered to the cavity of the throttle valve, the throttle valve, an air inlet channel and the like, and can also inhibit generating and aggregating deposits on the machine parts. The cleaning agent is made of environment-friendly materials completely, does not contain ingredients such as arene, halohydrocarbon and the like which have damage to a human body, has no toxicity and low odor, and does not pollute the human body, the environment and the atmosphere.

Description

Technical field [0001] The invention relates to a cleaning agent for automobiles, in particular to an environmentally friendly solvent-based cleaning and lubricating aerosol for throttle valves. Background technique [0002] The throttle valve is an important component of the intake flow control in the fuel electronic injection system. The front of it is the air filter, and the rear is the intake manifold and the engine block. It is the throat of the automobile engine. The cleanliness of the valve is very important. The direct causes of failures such as unstable idling, poor acceleration, increased fuel consumption, and difficulty in starting are inseparable from the cleanliness of the throttle. When these failures occur, the throttle must be checked and cleaned. [0003] Since there is no special cleaning agent for EFI throttle cleaning in China, maintenance personnel in the automobile maintenance industry can only use carburetor cleaning agent to clean the throttle, which often c...

AI Technical Summary

Problems solved by technology

Cleaning the throttle valve with carburetor cleaning agent will corrode and swell the oil seal of the idle motor, resulting in unstable idle speed of the engine and increased fuel consumption

[0005] 2. Carburetor cleaner has no lubricating effect

Cleaning with carburetor cleaning agent will completely wash off the original lubricant on the throttle valve, resulting in faults such as stuck operation of the throttle valve, poor operation of electronic throttle control and cruise control devices, etc.
