Can the trolley car engine be washed with water

Car engines can be cleaned with water.

Automobile manufacturers such as Shanghai Volkswagen and Shanghai General Motors will wash the engine assembly with water after assembly, in order to wash the oil remaining on the surface of the engine during the assembly process. But beware! Be sure to add a certain proportion of special rust inhibitor and cleaning agent to clean.

Otherwise, the surface of the engine will rust.

General Simple Law.

1) Connect the car air machine to the air nozzle.

2) Insert the power connector of the air machine into the cigarette lighter, or use the DC converter; However, do not start the engine. If the battery voltage is insufficient or too old, a DC converter or engine can be used instead.

3) Open the pull handle of the engine cover.

4) Use an air engine to clean the dirt in the bumps and recesses on the inside of the engine compartment cover.

5) Blow out the dirt on the air filter cover and in the recessed holes.

6) Blow off the dirt in the engine compartment heat insulation groove.

7) Blow off dust and sand particles in the spark plug holes.

8) Blow off the dirt from the drainage holes.

9) Blow off the dirt on the water tank and condenser heat sink.

10) Open the air cleaner set screw and remove the air filter.

11) Use the car air machine to clean the air filter (from the inside to the outside), if there is dust in the shell, you can wipe it off with a damp cloth, do not wipe the dust into the carburetor hole, you can cover the carburetor hole with a clean cloth first.

12) Use a vacuum cleaner to absorb the dirt attached to the outside of the air filter.

It can be washed with water, but try to be careful not to rush the water into the air intake and various line plugs.

Do not rinse with water when the car is hot. Because when the engine temperature is high, the sudden cold will cause the body to deform, crack, and may also affect the circuit, and the second is to prevent the high temperature from burning the hands.

1. Avoid the engine, outside the locomotive, the fresh-keeping box and the computer, avoid washing with a high-pressure gun, although there is a waterproof treatment, there is no problem with Lishui, but the pressure of the high pressure is larger, in case of damage to the circuit;

2. Don't go to the car wash right away after running the highway. After running at high speed, the car is in the stage of heat dissipation, whether it is the brake or the engine. At this time, washing the car and washing the brake disc with cool water will cause the steering wheel to tremble, and the brake system will fail, affecting driving safety;

3. Pay attention to the replacement of headlights to avoid; Pay attention to the lens and the headlights, and then use a high-pressure water gun to clean the engine, which may cause water to enter the body, so avoid it;

4. Although the engine, fuse box and wiring are waterproof, do not use a high-pressure water gun for a long time to wash. Some cars will have a warning on the fuse box in the engine compartment to prevent the high-pressure gun from washing through the area. Although there is a waterproof treatment, there is no problem with rainwater, but the pressure of the high-pressure water gun is large, so just in case, try to avoid the area of the driving computer and the outer fuse;

5. Cars that are more than three years old, or hybrid cars, must be wrapped with shrink film to wrap the wiring harness and the fuse box inside the engine when cleaning the engine, because after a long time, these plastic parts of the car begin to age, and the waterproof also begins to work, so it must be protected before washing;

The engine can be said to be a highly sophisticated mechanical part, and there are gaskets, sealing rings, etc. between each assembly, and even the oil cannot flow out of the instrument, is it possible for water to penetrate into it?

Of course not, unless your engine seal has become a big problem. However, this kind of engine generally belongs to the kind of broken machine with frequent failures, shaking, and stalling!

As long as it is a good engine, it will not penetrate into it, but it is still possible for water to enter the engine compartment, why?

Probably, because the engine also has two ports, an outlet and an inlet, which is what we often call intake and exhaust. And that's where the water gets to the engine!

Many cars have different arrangements for air intake according to the arrangement of the engine, but most of the exhaust is unified and hung at the rear. However, the ignition of the engine after wading will cause water ingress, not the water entering the air intake, but the water ingress caused by the suction of the exhaust port.

So you can rinse it casually? Of course not, there is still a trick to flush the engine compartment!

1. The water pressure should not be too high: because there are various circuits and electronic components in the engine compartment, such as motors and fuse boxes, if the water pressure is too high, a slightly damaged circuit will lead to a short circuit in the circuit, and the light one will burn the fuse, and the heavy one will directly burn the entire circuit board.

2. Do not flush the engine when it is at high temperature: the temperature of the engine will be very high after the car runs at high speed or after a long period of use. And now is the time of summer, the temperature is not a problem to fry eggs, at this time wash with water, due to thermal expansion and contraction, the engine block is prone to bursting, so that repairing is a trivial matter, directly change the engine!

It is best not to flush directly with water, the engine compartment is arranged with a lot of circuits, and direct flushing with water can easily lead to circuit failure.

The engine should not be washed with water, as water can damage the engine once it gets inside.

OK. Car engines need to be serviced regularly. When driving through some particularly humid or dusty areas, it is also necessary to do some inspection and maintenance of the relevant parts of the engine.

Change the oil and oil filter regularly.

As the oil passes through the pores of the oil filter, solids and sticks in the oil accumulate in the filter. If the filter is blocked, the oil will not pass through the filter element smoothly, and the filter element will be burst or the safety valve will be opened, and the dirt will be lubricated through the bypass valve, which will accelerate the wear of the engine and increase the internal pollution.

Extended Materials. Overheating of the engine will cause certain damage to the engine. If the temperature of the car engine is too high, the owner can carry out some checks:

The fan motor does not move or the fan clutch is faulty, and the temperature cannot be cooled properly.

The three-way catalytic converter is clogged or the tube is ruptured, causing the exhaust to be blocked, causing the engine to overheat.

The pipes of the cooling system are ruptured, causing coolant to be lost and heat dissipation not working properly.

After a long time of use, the water pump is highly worn, and the parts wear out and fall off.

If the lid pressure of the radiator is not the same, the spring will loosen and the cover will not be able to close tightly.

Thermostats that do not switch on and off properly are usually caused by mechanical failures or incomplete filling of the cooling system.

The engine of the car must not be flooded, and if it is washed with water, it will cause damage to the engine.

The water pressure should not be too high.

Because there are various circuits and electronic components in the engine compartment, if the water pressure is too high, a slightly damaged circuit will lead to a short circuit in the circuit, which will burn the fuse at least and directly burn the entire circuit board, and the consequences will be very serious.

1. It is best not to rinse the car engine with clean water, talk about luck only because when washing the car, the car must have just turned off, the engine is still in a high temperature state at this time, the current engine has two kinds of all-aluminum and cast iron, the general car uses cast iron, the working temperature of the engine is very high, the red-hot iron is poured with cold water, and the consequences can be thought about by yourself. In addition, the water vapor generated by cleaning the engine during the hot car will also penetrate into some electrical equipment.

2. Inside the engine compartment now, there are a lot of electronic components, all kinds of computers, sensors, actuators, motors, fuse boxes and wiring harnesses are all over the engine compartment, if you rashly use a high-pressure water gun to clean, these electronic components may be damaged. Whispering.

3. If it is some old models, it may also cause a short circuit, and it is not impossible to burn out the fuse or circuit board seriously! In addition, after cleaning the engine, the residual water droplets on the electrical interface will also accelerate its oxidation!
