What is the reason why the throttle won't catch fire after cleaning?

Throttle failure will lead to airtight cylinder, leakage of mixed gas, insufficient pressure in the cylinder, difficult ignition (and high voltage, that is, the pressure in the cylinder and the compression temperature of mixed gas can't meet the ignition conditions). In severe cases, the cooler can't touch the car, the combustion is incomplete, the locomotive has no electricity, and it will also cause fart (the exhaust pipe slams). There are two kinds of throttles: traditional cable throttle and electronic throttle. The traditional engine throttle control mechanism works by pulling a cable (soft steel wire) or a pull rod. One end of the cable is connected with the accelerator pedal, and the other end is connected with the accelerator linkage plate. The electronic throttle mainly uses the throttle position sensor to control the throttle opening according to the energy required by the engine, so as to adjust the intake air.

Under normal circumstances, just after cleaning the throttle, the engine burns residual cleaning agent, which is not easy to ignite at this time, but it is normal after many times.

He copied and pasted the throttle mindlessly to earn points. If you don't disassemble the throttle and clean it, spray it directly with carburetor cleaner, and the intake port will be filled with residual liquid of cleaner, which will affect the combustion. Just step on the gas pedal and light the fire. Spray the detergent several times. During this time, it will vibrate and gasp, or bombard the throttle many times. I do this every time I clean the intake manifold, even if the detergent is discharged, when the speed is stable.
