How to clean the car engine

First open the fuel tank cap, then take out the filter cartridge inside, use a hose to pump out the fuel in the fuel tank, leaving about 10-15 cm deep, then add 80 ml of ethanol gasoline to replace the cleaning agent, reinstall the filter cartridge, and then close the fuel tank cap
Disassemble the inlet and return pipes of the engine, and then connect the inlet pipe and return pipe of the engine with the inlet pipe and the return pipe of the no-disassembly cleaner, and use a special interface to connect the inlet pipe and the return pipe to form a loop.
The owner can add the fuel to the oil storage tank with the no-dismantling cleaning agent according to the scale on the oil storage tank of the no-dismantling cleaning machine or according to the number of cylinders of the car engine (generally about 100ml of gasoline per cylinder), and add 100ml of ethanol gasoline to replace the cleaning agent.
According to different car models, the pressure is appropriately adjusted, under normal circumstances, the EFI vehicle needs to adjust 2 to 3 pressures, and the carburetor model can be adjusted to a more appropriate pressure.
Start the car engine, check whether there is oil leakage in the oil inlet pipe and oil return pipe of the car, clean it for about 20 minutes at idle speed, and increase the throttle once when it is not about 4 minutes, so that the carbon deposits and water in the engine can be fully discharged from the exhaust pipe during the cleaning process.
Disassemble the oil inlet pipe and oil return pipe of the no-dismantle cleaner and the car engine to restore the entire oil circuit system to normal, start the car engine, and the owner carefully check whether there is oil pipe leakage.
Open the fuel tank cap of the car, then take out the filter cartridge inside, insert it into the bottom of the fuel tank with a thin tube from the fuel tank mouth, and then turn on the air pump to purge it with an air pressure of 3kg/cm, so that some impurities in the fuel tank will churn up and be cleaned off. Remember that when cleaning, the owner had better plug a clean rag at the mouth of the fuel tank, and constantly move the thin pipe to change the position for purging.
After the impurities at the bottom of the car's fuel tank are blown clean, the owner needs to drain the gasoline in the tank.
Depending on the situation, see if the fuel filter needs to be replaced.
At this time, the owner can refuel, start the car engine, and see how the car is doing.
