Is it necessary to clean the inside of the engine?

1. After a car has been used for one year or driven for 30,000-50,000 kilometers (this time and model have a lot to do with the driver, so please judge according to your own actual situation), there will be a feeling that the power of the engine is not as strong as that of the new car, the fuel consumption will also increase, the noise of the engine will increase, and the exhaust emission will be very different from that of the new car. In this case, it is necessary to clean the engine.

2. After the fuel enters the combustion chamber and burns with gasoline, it will produce gum in the intake valve, piston crown, piston ring groove, combustion chamber, spark plug and other parts, forming hard carbon deposit. At the same time, when the engine is working, the fuel and lubricating oil escaping into the combustion chamber will not burn completely, and the unburned engine oil will also form colloid after high temperature oxidation, which will adhere to the surface of the parts and form carbon deposit after high temperature.

3. Although these carbon deposit problems are small, they are extremely harmful, which usually lead to lax valve closing and engine performance degradation, which is manifested by a series of faults such as unsmooth acceleration, unstable idle speed, stall, jitter and knock.

Extended data:

Car cleaning is divided into ordinary cleaning and fine cleaning. Ordinary car washing is a traditional manual car washing and tunnel car washing. Because of its low cost and simple operation, it is favored by many riders.

The other is fine car washing technology, which originated in Europe, so it is also called "European fine car washing" and was introduced to China at the end of 20 10. Fine car washing refers to the cleaning inside and outside the car, which is more detailed and cleaner than traditional car washing. Car washing is a problem that every car owner or driver often faces, and car washing shops have gradually become a hot investment project in many large and medium-sized cities.

Because of the good service, many steps, perfect equipment and high cost, the price of fine car washing is slightly higher, so the service target is positioned at the middle and high-end car consumers, which is one of the main technical projects in the car washing industry.

There are many differences between fine car washing and traditional car washing. First of all, the fine car wash uses treated soft water instead of ordinary tap water, and even the flannel that wipes the car body is used with different parts of the car body.

First-class chassis high-pressure rotary cleaning agent and tornado interior cleaning equipment are also used for fine cleaning of vehicle chassis, engine, hub, inner cage, air conditioning port, trunk and other parts.

When cleaning paint surface, interior, door frame, engine and wheel hub, special towels with different colors should be used in corresponding parts to prevent cross contamination of bacteria. Deerskin and acid-free cleaning solution are used to clean the glass, and the deep protection of paint surface adopts the crystal plating protection technology of German Recanami car paint.

Finally, the car should be cleaned by high-temperature sauna, and the cage inside the car should be thoroughly disinfected and deodorized by Leica in addition to formaldehyde and tornado equipment. After a series of treatments, your car will look brand-new.

Cars should be cleaned and waxed frequently. After the end of the road salt season, the bottom of the car should be thoroughly cleaned, and the following points should be paid attention to when cleaning the car:

(1) The longer the salt, dust, insects, bird droppings and other sundries stick to the car, the greater the damage to the car. Clean them up in time.

(2) When washing the car with water, be careful not to spray water into the lock hole.

(3) If the car is sent to automatic cleaning equipment for cleaning, it is not necessary to remove the car with the roof antenna.

(4) The car body is stained with asphalt, oil stains, industrial dirt or insects. If it takes too long, they will damage the paint. Asphalt remover, insecticide, etc. Can be used to remove stains.

(5) When cleaning the paint surface of the car body, do not use brushes, coarse cloth, etc. So as not to leave scratches.

(6) When cleaning, spray with dispersed water to make hard dust and soil penetrate and be impacted, and then scrub with a sponge from top to bottom. Finally, use deerskin to wipe off the water.

(7) When cleaning the engine room, be careful not to splash water on electrical system components such as distributor and ignition coil. Otherwise it will make it difficult to start the engine. If water spills on electrical components, dry them with a dry cloth or blow them clean with compressed air, and remove the water from the distributor cover.

(8) After washing the car or driving in deep water, the braking effect may be reduced because the braking parts are soaked, so the braking effect should be judged by lightly stepping on the brakes. If the brakes are not normal, you should step on the brakes and drive at a low speed for a while to dry the brakes.
