What is the cause of carbon deposition in the throttle of EFI vehicle? Why?
Carburetor cleaning agent can effectively and quickly remove the glue formed in carburetor. Carburetor cleaning agent is a dry cleaning agent, and its main component is benzene. As the core component of the fuel supply system of gasoline engine, carburetor is used to mix air with gasoline and provide a certain proportion of mixed gas to the combustion chamber. Because the content of sulfide in gasoline in China is seriously exceeding the standard, the colloid formed by sulfide in gasoline will block the carburetor for a period of time, which will lead to the failure of carburetor control, unstable idle speed and poor acceleration. Maintenance workers need to maintain the carburetor, and the appearance of carburetor cleaning agent greatly facilitates the maintenance of the carburetor and improves the work efficiency.
With the continuous development of science and technology, today's carburetor gasoline engine has become the history of automobile development. The carburetor gasoline engine has been replaced by new and more advanced fuel electronic injection technology, and the gasoline engine in the car can no longer find the carburetor.
Unicorn accelerator cleaner? Clean the throttle? Carbon mud on the inner wall of the air inlet?
Throttle, as an important part of intake flow control of advanced fuel EFI system, has been widely used in engines. The special cleaning agent products for throttle maintenance will definitely replace the traditional carburetor cleaning agent products.
Since the launch of EFI vehicles, because there is no special cleaning agent suitable for cleaning the throttle of EFI vehicles in China, the maintenance personnel in the automobile maintenance industry can only use carburetor, but not clean the throttle. Causes engine idle failure, fuel consumption, throttle stuck, cruise system failure and other failures, and seriously causes engine cylinder pulling and other failures. Investigate its reason:
① Carburetor cleaning agent has serious corrosiveness and expansibility to aprons. Cleaning the throttle valve with carburetor cleaner will make the oil seal on the idle motor corrode and expand, which will lead to unstable idle speed of the engine and increase fuel consumption.
(2) The carburetor cleaner has no lubrication function. Cleaning with the carburetor cleaner will completely remove the original lubricating oil on the throttle, resulting in the failure of the throttle operation, electronic throttle control and cruise control device.
③ Generally, the inner cavity of electronic throttle is treated with special coating, which has the functions of anti-static, non-vacuuming and reducing the formation of colloid on its surface. Carburetor cleaning agent has serious damage to the special coating on the throttle valve, which leads to the increase of idle speed and fuel consumption.
④ Long-term use of carburetor cleaner to clean the throttle will make the throttle gum form faster and faster, and frequent cleaning will lead to frequent failures and high maintenance costs, which will eventually be solved by replacing the throttle.
There is something wrong with the air intake of the car throttle.
The air intake system of a car is equivalent to the human respiratory system, and the air cabin can't filter all the dust. Over time, the throttle will reduce its sensitivity due to the sludge formed by dust, and at the same time, the sludge will block the idle channel, pollute the idle valve, and affect the power, acceleration performance and fuel consumption of the engine.
solution
Clean the air intake system with unicorn air intake system efficient cleaning agent.
product performance
1.？ Thoroughly remove the glue and carbon deposit on the throttle, throat and intake pipe wall. ?
2.？ Improve the intake performance, restore the normal air-fuel ratio, reduce the exhaust emission, and make the engine idle more smoothly. ?
3.？ Improve combustion and reduce fuel consumption.
4.？ Harmless to oxygen sensor and catalytic converter.
application area
It is suitable for cleaning the air intake system of various gasoline vehicles.
Application mode
1.？ Use special cleaning equipment for cleaning.
2.？ Unscrew the bottle, pour the efficient cleaning agent of unicorn air intake system into the cylinder, and then tighten the bottle as it is. (When installing infusion bottles, be sure to install straws and sealing rings). Open the automobile hood (at the engine) and hang the cleaning bottle on the hood. Close the pressure regulating valve and ball valve for cleaning the infusion bottle and connect the vacuum compressor (air pump). Disassemble the throat of the engine intake pipe and extend the nozzle of the cleaning machine along the intake pipe to the vicinity of the engine throttle. Adjust the water inlet valve of the cleaning machine (pull the knob of the pressure regulating valve a little outward and turn it clockwise to open it to increase the pressure; Turn counterclockwise to close, depressurize) Adjust the pressure to 3 pressures, start the engine, open the discharge valve at the same time, and repeatedly spray the cleaning liquid into the throttle valve of the engine. After the cleaning solution is used up, run for 5 minutes and turn off the engine. The whole cleaning process takes 20 minutes. Remove the cleaning machine according to the procedure, and connect all parts of the engine to complete the cleaning.
3.？ Clean it every 20000 kilometers.
