Is the cleaning effect of automobile throttle nozzle great?

Is the cleaning effect of automobile throttle nozzle great? First of all, it is very useful for cleaning nozzles. Besides the throttle, the nozzle in the engine is the second largest place for carbon deposition. After driving for a long time, I began to shake and shake, and I felt very weak at first. Generally speaking, there is carbon deposit on the intake valve, which needs cleaning and maintenance. Today, Bian Xiao will talk about the maintenance and cleaning of the choke.

1. What is a choke?

The fuel injector for automobile is actually a simple solenoid valve. The electromagnetic coil is energized to generate suction, the needle valve is sucked up and the nozzle is opened. Fuel is ejected at high speed through the annular gap between the shaft pin of the needle valve head and the nozzle hole, forming mist, which is beneficial to full combustion.

Second, how often does the nozzle need to be cleaned?

The cleaning interval of the nozzle is generally recommended to be cleaned once every 20,000 kilometers. For ordinary car owners, every 30 thousand kilometers. In view of good car condition and good fuel quality, it can be extended to 40,000 ~ 60,000 kilometers. It is recommended to clean it once. Keep the nozzle clean with something like additives.

Third, the symptoms when the nozzle needs to be cleaned

When the first gear started, the car was a little shaky, and when the high-end gear accelerated, this phenomenon disappeared again. If all kinds of sensors on the vehicle work normally, the throttle check is normal and the circuit is normal, it is likely that the fuel injector is slightly blocked. However, when the high-end gear accelerates, the slight glue may be sprayed away again, and the performance of the car will be restored. This slight blockage of the fuel nozzle usually does not require cleaning. Because slight gum can be dissolved.

Fourth, how to clean

Cleaning the injector is like a doctor giving a drip to a patient in a hospital. "Hanging bottles" is a common maintenance method now, which is mainly used to clean the air intake and fuel system of the engine. The advantage of this method is that it is convenient and fast, and the engine can be cleaned relatively cleanly without disassembling the engine, and good results can be achieved.

The bottle on the left is filled with fuel system cleaner, which is responsible for cleaning the fuel system of the car, that is, the injector. The bottle on the right is responsible for cleaning the engine intake system, which is used to clean the throttle. The repairman needs to fix the bottle above the front box cover first, and then pour the fuel system cleaning agent into the bottle body on the left.

Five, the harm of not cleaning the nozzle

The environment where the nozzle is located is easy to produce carbon deposit, and some carbon deposit will stick to the nozzle head, resulting in nozzle blockage or untidy nozzle closure, sometimes affecting the injection angle, resulting in poor gasoline atomization and carbon deposit. Because the fuel is not good and the injector is not easy to use, the carbon deposition in the cylinder is serious; The accelerated wear of cylinder and piston ring will cause unstable idle speed, rising fuel consumption, weak acceleration, difficult start-up, excessive emission, complete blockage of injector and damage to engine.

Note: nozzle cleaning is also irregular, so you should not be careless when cleaning is needed. Remind mechanics to pay attention to the use of the engine during maintenance, and deal with problems in time to avoid further losses.
