Three tips for removing carbon from semi-trailers

First, do not idle for a long time

If the idle time is long, the time required for the engine to reach the normal temperature will be longer, and gasoline will evaporate slowly after being sprayed into the back of the valve, resulting in carbon deposition. Often idling together, the air flow into the engine is small, so the erosion effect of carbon deposition becomes very weak, will promote the accumulation of carbon deposition.

Two, the use of clean gasoline

Impurities in gasoline are the main components of carbon accumulation, so the trend of high cleanliness gasoline carbon accumulation is weak. However, we should pay attention to the high label is not equal to high quality, label only represents the octane number of oil, and can not represent the quality and cleanliness. In order to ensure the cleanliness of gasoline, some car owners will use gasoline detergent added to the practice of gasoline. This can effectively avoid the formation of carbon deposits on the metal surface, and can gradually activate the original carbon particles and gradually remove, so as to maintain the engine from damage. However, the increase of gasoline cleaner must be careful, if the addition of fake commodities will get the opposite effect.

Three, pay attention to the extinguishing time

For low plate semi-trailers equipped with turbochargers, do not turn off the engine immediately after high-speed travel or climbing, and then turn off the engine after 10 minutes of idle work. The speed of carbon accumulation of low plate semi-trailers equipped with turbochargers is several times faster than that of natural aspirated low plate semi-trailers. In the customary maintenance are satisfied with the conditions of every 20,000 to 40,000 kilometers to do the intake system free cleaning, that is, under the premise of the engine does not collapse with special equipment special methods for the vehicle's intake, valve, oil circuit and other simple components of the carbon deposition of the carbon operation.

How to identify the fault of ordinary semi trailer by sound

1, tapping sound: the sound is similar to heavy tapping, but the sound should be small. When this sound appears, the car mainly wants to think about whether the use of inferior gasoline, if the use of low quality oil may also appear popping sound.

2, heavy knock: like a dull knock on the door. This situation is mostly the internal cause of the engine, probably because of the aging of the vehicle, bearing or engine valve damage can also cause.

3, crash sound: a heavy metal iron impact sound, is likely to be the engine fixed frame due to serious wear for a long time, when the engine speed change will occur impact. But there may also be damage to the car's front and rear suspension, or too little transmission fluid caused.

4. Ticking: It may be that the universal joint of the drive shaft is damaged, or it may be caused by small stones beating tires or fan blades bending and loosening.

5, hum: This sound like the sound of bees, it is likely to be a loose parts, the bottom of the engine plastic or metal parts and air conditioning or compressor fixed support loose Z is common.

6. Hissing sound: Like a balloon leaking, most of them are faulty air-conditioning or cooling systems. If the cooling system had failed, you would have seen liquid at the bottom of the car. A large tire leak or a leak in the engine vacuum chamber can also cause the sound.

7. Whistling: Most of them appear when the car turns. The fan belt may be loose or worn. Sometimes the tire gas is insufficient, also appear this sound.

8, screams: very harsh, usually brake problems.

9, change the tone: the main motor aging issued by the discordant sound.

10, roar: from the car issued with a kind of "woof..." ". It could be a broken ball bearing in a wheel, compressor or water pump. It could also be a faulty air conditioner or compressor.
