Engine cleaning, what does it mean to hang a bottle, and whether to wash the oil circuit or the gasoline oil circuit. Which dirty dongyang engines are mainly washed?

Because the automobile fuel distribution system is very precise, it can't be disassembled casually. When cleaning the engine fuel system, use the engine disassembly-free cleaning agent, because there is no need to disassemble the fuel system, on the one hand, it can start to clean the fuel system thoroughly, on the other hand, it is beneficial to protect the engine fuel system.

The operation process of cleaning oil circuit and oil tank with disassembly-free cleaning agent;

1. Open the fuel tank cover, take out the filter cartridge, pump out most of the fuel in the fuel tank with a hose, leaving fuel about 10~ 15 cm deep, add 80ml* brand ethanol gasoline to replace the cleaning agent, install the filter cartridge, and cover the fuel tank cover.

2. Dismantle the oil inlet and oil return pipe of the engine, connect it with the oil inlet and oil return pipe of the disassembly-free cleaning machine, and connect it with a special interface to form a loop.

3. According to the size of the oil storage tank or the number of engine cylinders (per cylinder 100ml gasoline) of the disassembly-free cleaning machine, add gasoline to the cleaning agent storage tank, add 100ml* brand ethanol gasoline, and replace the cleaning agent.

4. Adjust the pressure according to the vehicle type, the carburetor truck can adjust the appropriate pressure, and the EFI truck can adjust 2-3 pressures.

5. Start the engine, check whether there is oil leakage in the oil inlet and return pipes, clean at idle speed 15-20 minutes, and increase the throttle every 3-5 minutes, so that the cleaned carbon deposit and moisture can be discharged from the exhaust pipe.

6. Remove the disassembly-free cleaning machine and the oil inlet and return pipes of the engine, restore the oil circuit of the automobile, and start the automobile to check whether the oil pipe leaks oil.

7. Open the fuel tank cover and take out the filter cartridge; Connect the air pump with a soft air pipe, insert the hose into the bottom of the oil tank from the mouth of the oil tank, and blow with the air pressure of 3kg/cm, so that all kinds of impurities accumulated at the bottom of the oil tank are washed away by the churning gasoline. When cleaning, it is best to block the oil tank mouth with a clean cloth and constantly move the hose purging position.

8. When it is confirmed that the impurities at the bottom of the oil tank have been blown clean, immediately drain the oil in the oil tank. Special reminder is that the oil discharged from the crude oil tank must be filtered and precipitated before it can be added to the oil tank.

9. Replace the fuel filter (as the case may be).

10, add ethanol gasoline or regular gasoline, start the engine and test drive.
