After running the mini hot car, the engine has been turned off and the throttle can't be added. The throttle has just been emptied.

1. After cleaning the throttle, matching is required. The matching method of each car is different. After cleaning the throttle, it is necessary to pull up the speed to discharge the carbon deposit.

2. Smoke and exhaust explosion are caused by poor atomization and incomplete combustion of gasoline. I have to go to the repair shop for inspection.

3. Unplug the negative electrode of the battery and put it back in a few minutes. In addition, check whether the plug of the throttle position sensor is loose.

When cleaning the throttle valve, it is not necessary to disassemble it, but the sealing part of the inlet steam must be cleaned, and the idle motor must be disassembled for cleaning. There are advantages and disadvantages of cleaning nozzles by borrowing and disassembling. Generally speaking, the maintenance station suggests disassembling and washing, which can prevent other unnecessary waste, such as replacing the sealing ring after disassembling, installing other gaskets, or delaying the owner's time because of oil and gas leakage when disassembling.

If there is too much sludge in the throttle, it may cause poor engine acceleration and increase fuel consumption, which is a big worry for the owner. Just clean it up

When cleaning the throttle valve, first remove the intake throat to expose the throttle valve, remove the negative electrode of the battery, turn off the ignition switch, straighten the throttle plate, spray a small amount of "carburetor cleaner" into the throttle valve, and then carefully scrub it with a polyester rag or a high-spin "non-woven fabric". Deep in the throttle, you can hold a rag and scrub it carefully where your hands can't reach it.

After cleaning, the throttle will be initialized according to the disassembly procedure just now. After cleaning the throttle, it needs to be initialized, because the computer has a memory function when adjusting the throttle opening, because there was sludge blockage in the past. In order to ensure the air intake, the computer will automatically adjust the throttle opening to keep the air intake in a normal state.
