How much does it cost to clean the nozzle throttle valve?

The cost of cleaning the nozzle throttle valve is around 300 yuan, and the function of cleaning the nozzle throttle valve is as follows: 1. The nozzle of the automobile nozzle is the most precise part in the automobile, and the engine mainly burns gasoline when working. During the combustion process, due to high temperature, carbon deposits are generated on the surface or pores of the fuel injector, and at the same time, more gum will be deposited on the inner wall of the fuel injector and the surface of the needle valve during long-term use, which will affect the fuel injection effect, block and stick the fuel injector, resulting in oil leakage, poor atomization and even no fuel injection, leading to increased fuel consumption, decreased engine power, unstable idle speed, poor acceleration and difficult cold start. 2. The fuel injector used in the car is actually a simple solenoid valve. When the electromagnetic coil is energized, suction is generated, the needle valve is sucked up, the nozzle hole is opened, and fuel is ejected at high speed through the annular gap between the shaft pin at the head of the needle valve and the nozzle hole, forming mist, which is beneficial to full combustion; 3. There are also phenomena such as weak acceleration, loud noise, high fuel consumption and car shake. So be sure to clean it regularly. Generally speaking, just after cleaning the throttle and nozzle, the fuel consumption will increase, because the oil circuit is smoother than before, so it costs oil.
