What causes the car engine to pull the cylinder

The reasons for the engine pulling the cylinder are as follows: 1. The engine cooling system is not replenished in time due to leakage, lack of water and overheating; the engine leaks or consumes too much oil, resulting in serious oil shortage; the engine runs at high speed or overloads for a long time, and the temperature is too high; the piston pin or cylinder set is poorly matched, resulting in deformation.

The main reasons for pulling the cylinder are as follows: the gap between the piston and the cylinder is too small; poor lubrication between the piston and the cylinder, oil selection is wrong; the piston ring is broken, bites the piston, or the piston pin chuck is broken or falls off; on the side where the piston and the piston ring are dumped, it is pressed on the cylinder wall.

Most people thinkThe engine cylinder pulls because the oil is not lubricated, or it is caused by the aging of the oil. This sentence is true, but not all of them are true. In fact, there are many reasons for the engine to pull the cylinder. In addition to the oil problem, such as the wrong size of the piston parts and the insufficient running-in of the engine, it may also cause pulling the cylinder.

What is the reason for the pulling of the cylinder of the car engine?

The reason why the engine pulls the cylinder: whether the size of the cylinder liner used during assembly does not match the cylinder block and piston; the air filter is not sealed, which makes the filtration effect worse, and the dust, sand and other impurities in the air are sucked into the cylinder, forming abrasive wear; poor grinding. The lubricating oil film of the new machine or the overhauled engine has not yet been formed.

If the engine has poor operation of the lubrication system, the surface of the accelerated parts is not lubricated, so that the parts are burned at high temperature, the shaft tile is burned, the shaft is hugged and the cylinder is formed. Therefore, the lubricating oil is very important to the operation of the engine. A little carelessness will reduce the service life of the engine.

The main reasons for pulling the cylinder are as follows: the gap between the piston and the cylinder is too small;Poor lubrication between the piston and the cylinder, oil selection error; the piston ring is broken, bites the piston, or the piston pin chuck is broken or falls off; on the side where the piston and piston ring are dumped, it is pressed on the cylinder wall.

What is the reason why the car engine pulls the cylinder?

1. The reasons why the engine pulls the cylinder are as follows: 1. The engine cooling system is not replenished in time due to leakage, lack of water and overheating; the engine leaks or consumes too much oil, resulting in serious oil shortage; the engine runs at high speed or overloads for a long time, and the temperature is too high; the piston pin or cylinder set is poorly matched, resulting in deformation.

2. Poor operation of the engine lubrication system: insufficient oil will reduce the amount of oil pumped and no oil will be pumped, resulting in a decrease in oil pressure, and the crankshaft and bearing will lose normal lubrication conditions;In addition, the cylinder liner and piston also pull the cylinder due to dry friction caused by the reduction of splashed oil.

3. The main reasons for the engine to pull the cylinder are: improper assembly during overhaul causes the cylinder to pull.

4. Reason 3: The engine runs at high speed. When the engine is running at high speed, especially under empty load, the most common consequence is that the vehicle engine explodes, which causes the problem of pulling the cylinder of the engine.

What are the reasons why the engine pulls the cylinder?

The main reasons for pulling the cylinder are as follows: the gap between the piston and the cylinder is too small; poor lubrication between the piston and the cylinder, and the oil selection is wrong; the piston ring is broken, biting the piston, or the piston pin chuck is broken or falling off; on the side where the piston and the piston ring are dumped, it is pressed on the cylinder wall.

The reason why the engine pulls the cylinder: whether the size of the cylinder liner used during assembly does not match the cylinder block and piston; the air filter is not sealed, which makes the filtration effect worse, and the dust, sand and other impurities in the air are sucked into the cylinder, forming abrasive wear; poor grinding. The lubricating oil film of the new machine or the overhauled engine has not yet been formed.

The reasons for the engine cylinder pulling are: the engine cooling system causes the engine overheating due to leakage, lack of water, and failure to replenish in time; the engine oil leakage or oil consumption is too large, resulting in serious oil loss; the engine is running at high speed or overloaded for a long time, and the temperature is too high; the piston pin or cylinder set is poorly matched, causing Deformation.

What causes the engine to pull the cylinder?

The main reasons for pulling the cylinder are as follows: the gap between the piston and the cylinder is too small;Poor lubrication between the piston and the cylinder, oil selection error; the piston ring is broken, bites the piston, or the piston pin chuck is broken or falls off; on the side where the piston and piston ring are dumped, it is pressed on the cylinder wall.

The possible reasons for the engine's cylinder pulling are mainly: improper assembly during overhaul causes the cylinder pulling.

The engine lubrication system does not work well: the amount of oil is insufficient, which will reduce the amount of oil pumped and the oil cannot be pumped, resulting in a decrease in the oil pressure, and the crankshaft and bearing will lose the normal lubrication conditions; in addition, the cylinder liner and piston will also pull the cylinder due to dry friction due to the reduction of splashed oil.

What is the reason why the car engine pulls the cylinder?

1. The engine cooling system overheats due to water leakage and lack of replenishment in time.The oil is too low, causing the cylinder to lose its airtightness and lubrication function. The piston ring broke and scratched the cylinder wall. The piston pin ring fell off and scratched the cylinder wall. The piston ring is stuck in the ring groove due to carbon accumulation and loses its sealing function.

2. If it is a failure caused by oil, the main reason is that the viscosity of the oil is improperly selected, and the oil is selected according to the above content.

3. If the engine water temperature is too high, the cooling system will lack water, so that the cooling water cannot circulate and dissipate heat, resulting in excessive engine temperature. At this time, part of the cooling water will be evaporated. If it is not replenished for a long time, once the pump does not pump water, it will cause the engine to have a high temperature due to lack of water.

4. Personally, I think there are two reasons why the car pulls the cylinder. The first point is that there is a problem with the car's radiator, resulting in the internal temperature of the engine being too high, resulting in the engine cylinder bursting;The second point is that due to too much carbon accumulation inside the engine, the fuel combustion is insufficient, which will also lead to the engine cylinder burst.

5. The main reasons for pulling the cylinder are as follows: 1) The gap between the piston and the cylinder is too small. The gap between the piston and the cylinder should be strictly in accordance with the provisions of the diesel engine instruction manual. If the gap is too large, it will make it difficult for the diesel engine to start cold. When the engine is cold, it will make a knocking sound and the power will decrease at the same time. If the gap is too small, it will cause failures such as pulling the cylinder and swelling the cylinder.
