Can the engine be cleaned directly with water?

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!

1. The automobile engine can be cleaned with water, the purpose is to wash the oil remaining on the surface of the engine during the assembly process. But beware! The hall must be cleaned with a certain proportion of special rust inhibitors and cleaning agents. Otherwise, the missing hidden surface of the engine watch will rust.

2. Before you want to clean the engine, you must make sure that the engine block has been cooled to a normal temperature, if the engine cylinder body temperature is too high, once in contact with cold water, the cylinder block is easy to crack, which may lead to cracking of the cylinder block, and the water vapor generated will make the humidity in the engine body too large, resulting in the service life of other engine parts.

3. Do not wash after high-speed driving or long-term driving. Because at this time, the brake disc and brake pads are in a state of heat dissipation, and washing the brake disc with cool water at this time will lead to the instability of the steering wheel in the future, and even lead to the failure of the braking system.

Hello! 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.

No, because once the engine does not release water well, it will cause water to enter and damage the engine.

Engine cleaning can directly add the cleaning agent to the fuel tank in a certain proportion and carry out internal circulation cleaning in the normal operation of the car; The other method needs to be supplemented by special equipment, which is cleaned when the engine is idling, and finally the decomposed carbon gelatinate is discharged with the exhaust gas.

Regular cleaning of the engine interior is one of the indispensable items for regular maintenance of the car. In the process of working the engine, with the high temperature working environment of the engine; Relative movements, wear from friction surfaces, and flammable gas mixtures that escape from the inside of the cylinder into the crankcase can all have an impact on the performance and quality of the oil. When the performance and quality of the engine oil deteriorates, its ability to clean the engine oil passage will also decrease, and eventually lead to the accumulation of oil sludge in the engine lubrication system, and even block the oil passage in serious cases.

Therefore, the engine lubrication system needs to be cleaned regularly.

Cleaning every 2-40,000 kilometers, the cleaning cycle should be adjusted according to the actual situation. Vehicles with particularly dirty engines need to disassemble the oil cap and oil pan for cleaning, which is usually carried out by maintenance professionals.
