Why rain car has unpleasant smell?

When the air conditioning

Very often smelt rancid taste

Recent heavy rains in the country

The smell is not thicker

The reason is likely to pass over the engine compartment

Do not believe went to see engine

Certainly cover a thick layer of ash

Even have imprinted on the soil insulation cotton cover machine

When faced with this situation

Water washed feel is the best solution

But the engine can wash with water?

Held two general views

View: wash with water is not directly nacelle. These small electronic partners that are used in automotive fuel injection control system, an engine compartment with an engine computer, transmission computer, the ignition computer and various sensors and actuators, which are controlled by the voltage of the electronic components, if contact with water , damage to the engine computer. Furthermore, if water remains in the engine compartment, electrical interface oxidation over time can lead to poor contact, screws, rust and other issues, and want to repair these parts anywhere from several hundred to as many as tens of thousands, really more harm than good.

Second point: Many older drivers feel all right. Those off-road vehicles Why can wade water swept over the body? The water will enter from the grille to the engine compartment and the engine compartment of electrical equipment as well as safety relays and so do the waterproofing treatment, so the engine can be rinsed with water!

With questions we are to understand two issues:

A: layout nacelle

Engine compartment harness interface has waterproof treatment, including a battery, an engine, an air cleaner, spark plug and other components. Even so, but I do not actively using high-pressure water jet to wash these parts, after all, there are so many engine compartment components and wiring harness electrical interfaces, and no one will take such a risk premise uninformed.

Two: How water into the engine?

The engine may be said to be a high-precision mechanical components, and are added between each fitting gasket, sealing ring, the instrument even can not flow out of the oil, the water is not possible to go. Ignition engine will turn off after wading in the water, the water is suck exhaust port due.

So that you can easily wash up?

of course not!

Flush the engine compartment still has skills!

1, the water pressure is not too high

Consequences: damage electronic circuit

Since the nacelle which have a variety of circuits, electronic components, such as the motor, the fuse box, if the pressure is too high, a little broken line will cause a short circuit, the light burned fuses, severe burning of the entire circuit board directly.

2, when the engine is not flush temperature

Consequences: cylinder burst

When rinsed with water temperature is too high, thermal expansion and contraction, the engine block is prone to burst, so that the engine may be directly for!

3, the headlight is not rinsed with water cannons

Consequences: severe fog headlights

Headlamps will leave ventilation holes, used to heat dissipation headlamps, under the pressure of high pressure water gun, water is still there will be some "pressure" into the lampshade, very difficult to remove!

4, the final clean-up

Washing the engine compartment, the smell also cleaned up, we only need a towel to dry the water in the engine compartment, and then start the engine with the heat from the engine to "evaporated and the" engine compartment water can be friends! We all learn it?

Why some drivers change lanes without turn signal?
