The formation of car carbon deposits is due to some impurities in gasoline. If the use of relatively high cleanliness gasoline, then the formation of car carbon deposition will be less. If some car cleaners are used, the carbon deposits formed on the metal surface can be activated.
Attentive car owners will open the hood, check the engine operating conditions, will dip the oil dip to see the oil color, then it can be clearly seen that the oil has deteriorated, black, how the oil color will darken, black, added The time is clear and clean.
What is sludge?
The sludge produced in different parts of the engine can be classified into low-temperature sludge and high-temperature sludge. Low-temperature sludge is a combination of helium (containing unburned fuel and water) and oil to produce low-temperature sludge. When the engine is operating at a low temperature, the moisture and fuel in the crankcase are not completely evaporated and emulsified, resulting in the production of sludge.
What are the hazards of sludge?
1. A large amount of sludge adhered to the inner wall of the crankcase will reduce the cooling capacity of the cylinder, causing the oil temperature to be too high and the power of the engine to drop.
2. There are a lot of sludge in the oil passage inside the engine, which will increase the flow resistance of the oil and reduce the flow of the oil, thus affecting the lubrication effect of the oil.
3. Excessive sludge will clog engine oil passages, resulting in lack of lubrication between engine parts, and in severe cases, causing burnt watts, holding shafts, etc.
How to remove sludge?
Today's engine oils are accompanied by some cleaning agent that removes carbon deposits or sludge. They can effectively disperse the sludge. This is why the color of the engine oil is darker when we change the engine oil. However, if the oil quality is not good, or if the oil is used for a long time, it will be degraded. This will not effectively remove the sludge, which will result in the accumulation of sludge and affect the operation of the engine.
If you do not maintain the engine for a long time, the internal sludge of the engine is severe, and you can only dismantle the engine for cleaning. As the engine is disassembled and reassembled, its power and sealing performance will be inferior to that of the original machine. Therefore, in general, cleaning the carbon deposit and sludge in the cylinder of the engine should not be carried out frequently. When it is a last resort, it must go to a regular maintenance factory, otherwise the performance of the engine will be greatly reduced.
Hard Tube Assembly
Auto Ac Expand Tube Joint :applied in R134a auto ac refrigeration system. In order to decrease the weld joint to avoid the leakage, we change press plate and tube braze structure into press plate and expand tube . Below construction has been successful in ZOTYE - T22.S21.JT11 ,mass production quantity reach into 200,000pcs with stable quality .The coaxial tube of automobile air conditioning system is mainly used in R134a refrigerant air conditioning system. It can enhance the refrigeration effect of automobile air conditioning system. It has begun in the ZOTYE project A40 and JAC project S7.M432.
