When is the throttle nozzle cleaned?

The throttle valve is cleaned every 20,000 kilometers, and the fuel injector is cleaned every 2 years and 60,000 kilometers. If you don't clean it often, the fuel consumption will increase and the power will decrease, so it is best to clean it regularly. Cleaning the throttle valve is not as frequent as possible. Excessive cleaning will gradually wash away the special coating of the throttle valve cavity, and the coating will be lost in the cavity, which is more likely to cause sludge adhesion. The injector has two failure modes: 1. When using inferior gasoline, because there are too many impurities in the fuel and the injector is blocked, the power of the car will be reduced and the speed will be slowed down; 2. Carbon deposition in the fuel nozzle is caused by insufficient fuel combustion for a long time. If you are used to driving in high gear and low speed, idling for a long time will accelerate the carbon deposition on the engine. After carbon deposition in the fuel nozzle, poor fuel atomization and insufficient fuel combustion will cause the engine to enter a vicious circle, which will reduce the engine power and increase the fuel consumption beyond the standard.
