What is the reason for the engine decylinder?

Cause of engine decylindering: the engine pulls the cylinder, that is, the piston or piston ring pulls out the inner surface of the cylinder hole or pulls out the groove. This failure mostly occurs during the new car closing period (including overhaul).

There are two common reasons for cylinder shedding: damaged piston, broken valve head, broken connecting rod bolt, etc., which affect the cylinder material. The engine cylinder liner and piston ring have a large wear gap, the intake and exhaust valves are not tightly closed, and the leakage of the valve oil seal affects the insufficient pressure of the cylinder, resulting in cylinder shortage.

At high, medium and low speeds, the engine works unevenly and rhythmically. The silencer exhausts black smoke and fires the cannon. The engine cylinder pull refers to the excessive cooperation between the piston and the cylinder. The inner wall of the cylinder is scratched by the piston with deep grooves. The friction of the piston, piston ring and the cylinder wall loses sealing, resulting in a decrease in the compression pressure of the cylinder and the loss of power.

What is the cause of the engine decylinder?

1. There are two common reasons for cylinder shedding: damaged piston, broken valve head, broken connecting rod bolt, etc., which affect the cylinder material. The engine cylinder liner and piston ring have a large wear gap, the intake and exhaust valves are not tightly closed, and the leakage of the valve oil seal affects the insufficient pressure of the cylinder, resulting in cylinder shortage.

2. The reason for the engine cylinder disconnection: the engine pulls the cylinder, that is, the piston or piston ring pulls out the inner surface of the cylinder hole or pulls out the groove. This failure mostly occurs during the closing period of the new car (including the overhaul).

3. At high, medium and low speeds, the engine works unevenly and has rhythmic vibration, and the silencer discharges black smoke and fires cannons. The engine cylinder pull refers to the excessive cooperation between the piston and the cylinder. The inner wall of the cylinder is scratched by the piston with deep grooves. The friction of the piston, piston ring and the cylinder wall loses sealing, resulting in a decrease in the compression pressure of the cylinder and the loss of power.

4. The operation of the engine without a cylinder will bring great harm: the speed and power of the engine will decrease. Increase fuel consumption and emission pollution. It aggravates the wear of the operating parts and shortens the use cycle of lubricating oil.

How to solve the problem of engine decylinder?

Dealing method of engine cylinder removal: automobile cylinder removal is also the lack of cylinder of automobile engine.

The solution to the engine decylinder: How to get rid of the fault problem of insufficient cylinder? I believe that Mr. Yi has experience. Start the engine and unplug each ignition coil. For example, the first task is to pull out an ignition coil. The engine shook more.

Dealing method, check the spark plug, measure the insulation of the cylinder wire with a shaker, and measure the high-voltage coil with a meter to see if there is something wrong with that one. It should be fine if it is replaced.

There are also some cars that are not well fixed between the body parts, which may cause abnormal sounds. Generally, it can be solved by tightening the screws. Solution: Check the trunk or rear row of the car first.Whether there are objects that are not fixed, easy to roll and make sounds on the seat, and exclude some items that are not fixed and make noise.

What's wrong with 17 Hyundai Rena burning engine oil decylindering

Natural wear. With the increase of the mileage of the car, the wear between the piston and the cylinder gradually increases. When this wear increases to a certain extent, the cylinder will begin to run out, and the phenomenon of oil burning will occur. When the valve oil seal is damaged, the phenomenon of burning oil will be more obvious. Improper maintenance.

The valve seal is corrosion-aging and the sealing performance is invalid. In addition, there is a crankcase ventilation system (exhaust valve) in the car now. If there is a problem, it will also increase the consumption of oil. In the past, the problem of burning oil could only be solved by disassembly and repair. Now there is a plan to solve the problem of burning oil without disassembly and repair.

Quick acceleration burning oil: blue smoke will come out in the process of idling or rapid acceleration; reason analysis: the inner wall of the cylinder and the piston ring are poorly sealed; burning oil at any time: whether it is cold start or rapid acceleration, blue smoke will appear.

The lack of oil in the Rena car leads to the low oil level. In this case, the oil pump cannot absorb the oil, or absorbs part of the oil, and the engine lubrication is not good. For a long time, the parts will be excessively worn and the oil will burn. Information expansion: "Burning engine oil" means that the engine oil enters the combustion chamber of the engine and participates in the combustion together with the mixed gas.

The main reason for burning engine oil is to use oil of poor quality or viscosity level that does not meet the requirements. Low oil quality level will lead to increased wear. In addition, if the viscosity of the oil is too low or too high, it will cause poor engine lubrication, which will increase the wear of the piston ring and cylinder wall, and the sealing performance will decrease, resulting in oil burning.

There are many unexpected places where oil leakage may also occur. In fact, oil leakage is not such a terrible thing. I'm afraid that the engine can be fully lubricated. Of course, in addition to the phenomenon of oil leakage, many engines also have the phenomenon of burning oil, but any phenomenon is It's not a good thing.

What does it mean to de-cylinder the engine?

Car engine decylinder is also a lack of cylinder in a car engine: engine cylinder deficiency mainly refers to one or more cylinders in the engine that do not work properly.

First: Anal prolapse is the prolapse of the rectum or part of the sigmoid colon or muscle layer. 1st degree anal prolapse refers to mucosal prolapse, which can be self-retropation. Second-degree anal prolapse refers to the prolapse of the mucous membrane and part of the muscle layer, which can be reinsorted by itself or with the help of technique.Third-degree anal prolapse refers to the full-layer prolapse of the anal canal and rectum, which cannot be recovered.

Explanation of anal prolapse [prolapse of the anus] rectal anal canal prolapse from * Detailed explanation of the disease name. Anal canal and rectum self * prolapse. Long-term constipation, diarrhea, hemorrhoids, etc. can be caused.

The sudden shutdown of the car while driving is due to anal prolapse. Check whether there is any abnormal noise, and learn to distinguish the abnormal noise that belongs to the reasonable noise. It is difficult for ordinary car owners to distinguish which are faulty abnormal noises and which are reasonable abnormal noises. When I went to the repair shop to test the abnormal sound of the vehicles, only nearly 20% of the vehicles really had problems.
