The throttle is dirty. Does it cost gasoline?

Of course, there are two ways to clean the throttle. One way is to clean the throttle body with carburetor cleaner (Hua Qing for short) (or not to take it off directly in the car, and then spray clean fuel after wiping it), and the other way is to maintain and clean the engine intake without disassembly (spray the throttle with cleaner or a cylinder with its own pressure, and add and subtract the throttle continuously to keep the engine running). Dirty throttle, fuel consumption: 1. Malfunction of fuel system and fuel injector: uneven fuel injection and poor atomization of fuel injector cause power imbalance of each cylinder. Frequently encountered reasons are: injector blockage, poor sealing, injection linearity and so on. 2. Fuel pressure fault: the oil pressure is too low, the fuel sprayed by the injector is in poor atomization state or the sprayed fuel is linear. If it is strictly prohibited, only spray droplets, reduce the amount of spray to make the mixture too thin; 3. The oil pressure is too high, and the actual fuel injection quantity causes the mixture to be too rich. Common reasons are: fuel filter is blocked; The fuel pump filter screen is blocked; The pump capacity of fuel pump is insufficient; The elasticity of fuel pump spring is too small; Deformation of oil inlet pipe; Fuel pressure regulator is faulty; The oil return pipe collapsed and was blocked.
