What is an engine pull cylinder ? What causes the pulling cylinder ?

The main reason for engine cylinder pulling is the formation of an oil film between the cylinder wall and the ring and plug. In the range of motion of the plug and plug ring, the friction surface does not maintain good lubricity, resulting in varying degrees of longitudinal or extensive mechanical wear. As the economy continues to grow, everyone's life is getting better and better.

In the past, the jealousy of seeing someone else's car in their home has been ingrained. And, when you grow up and buses are born, when you travel, you will always see which car has the shortest distance, is more convenient, and does not need to be reversed.

Socio-economic conditions are now more developed than before. No matter where you go, many people just need to drive, just like there are a lot of people in the family now, and going out to play is not a problem. Lots of space in the car, no worries.

Many people have a lot of quality of life after owning a car. But when it comes to cars, many people don't care when something goes wrong with the car, but small problems are often the biggest harm to cars. The oil problem.

In addition to changing the oil according to the normal cycle, it is also necessary to choose the right viscosity oil to keep the plug in a good lubricated state.

Since the nature of the lubricating oil has a great influence on the oil film, too low viscosity will make it difficult for the oil film to form, or the oil film will be too thin, which will aggravate the wear of the plug. The plug part is not the correct size. From the perspective of design factors, the size of parts such as plugs and plug rings is too large, and the assembly gap between the plug and the cylinder wall is too small, which may lead to cylinder pulling.

Insufficient engine break-in. For most models, a new or overhauled engine requires some simple break-in. The surface looks smooth, but in fact, it has micron-sized high-altitude protrusions.

If the test run is not carried out according to the regulations, it will cause early wear and tear, and in serious cases, a cylinder pulling accident will occur. The engine was hot. If the water temperature gauge sounds an alarm and continues to drive, it will also cause the engine to pull the cylinders, as the engine expands and contracts after high temperatures, causing the gap between parts to become smaller, and dry grinding.

There's too much carbon on the plug. For cars with aluminum alloy cylinder walls, be sure to check the carbon deposits on the top of the plug. If the engine deposits too much carbon, it will fall into the plug side and cylinder wall after automatic peeling.

In this way, the carbon deposits will dry grind along with the cylinder wall and eventually scratch the cylinder.

It means that the engine is faulty, the inner wall of the cylinder is scratched or scratched, the engine will be difficult to start, and there will be automatic stalling; It may be that the gap of the piston is relatively large, or it is relatively small, or it may be that the material of the piston is not particularly good, or there is a particularly large error in the size of the manufacture.

It is a situation in which the piston of the engine is in motion, causing scratches to the engine block. The gap of the fit is too much, the situation of small lubrication is not good, the lack of lubricating oil, the volume of the piston is relatively large, and it is hindered by some power.

It refers to the problem with the inner wall of the cylinder of the car, which is generally caused by the change and reduction of the compression pressure of the cylinder.

The term means that the engine cylinder wall is scratched, usually caused by damage to the piston ring.

Engine cylinder pulling refers to the failure of obvious longitudinal mechanical scratches and scratches in the cylinder within the range of motion of the ring. In severe cases, fusible wear can occur, making it difficult to start the engine or stall automatically. Pulling the cylinder is a major thing for the engine.

The fundamental reason for pulling the cylinder is that it is difficult to form an oil film between the cylinder and the ring, resulting in poor lubrication and even dry friction.

In fact, the so-called cylinder pull is caused by the engine. During the work, for various reasons, there are signs of hanging injuries on the cylinder wall or crankshaft. When the piston, ring, and cylinder walls rub together, they lose their seal, resulting in a decrease in cylinder compression pressure.

In this case, the engine will make abnormal noise, the power output will drop rapidly, and there will be severe oil combustion and blue smoke, which will seriously lead to the crankcase**.

Insufficient lubricating oil or interruption of oil supply, direct contact with metal pull cylinder; In addition, in order to obtain an effective break-in in the shortest possible time, the break-in time and load distribution must be taken into account. Under low load, even if the run-in is long and long, the run-in cannot be completed. If you rush to run in under high loads, this will cause the cylinder to pull.

The cylinder is in the cylinder, the piston is seriously thermally deformed or the top is burned and melted will cause the car cylinder to pull, which requires the owner to check the car frequently and pay attention to maintenance.

In daily driving, it is necessary to operate and use the engine reasonably, do not overload the operation, do not move the accelerator, and do not start without water, which can effectively prevent the occurrence of the car cylinder. When the engine starts at a low temperature, the lubricating oil has high viscosity and poor fluidity, and it is difficult to form an effective oil film in the cylinder. According to the test of the research department, when the diesel engine is working under a load of cooling water temperature below 30, the wear and tear of cylinder liners and other components is 5 7 times that of normal water temperature.

The engine overheated. When the cooling system is not properly maintained or overloaded, excessive machine temperatures will not only reduce the mechanical strength of the parts, but also prevent the formation of a lubricating oil film on the cylinder. After the parts are heated and expanded, they are easy to get stuck in the cylinder liner.

The result was partial melting, damaged cylinder liners, forcing the engine to shut down. In practice, the drawing of a cylinder is often the result of a combination of factors. For example, if an unbroken engine is put into full operation immediately after a cold start, a cylinder pulling accident is likely to occur.

Pulling the cylinder means that in the process of driving, there are obvious scratches on the cylinder; It may cause engine damage, automatic stalling, and it is difficult to start the phenomenon, and it will emit various noises of various simple bush races, and there will be oil combustion.

In fact, the bar of the engine has been damaged to a certain extent, so it is called the pull bar, the side balance engine will have abnormal noise, and the power of the engine will also be affected to a certain extent, and the overall horsepower will also be insufficient to fight the spike, and it is easy to cause the problem of stalling when the silver is transported.

The engine cylinder pulling is to cause some automatic stalling of the seepage crack motive; It will accelerate the aging of the lead wax engine, cause some damage to the engine, wear and tear and cause serious failure of the engine, resulting in the engine being unable to work normally.

The cylinder of the engine "pulls" the engine has obvious scratches, which will cause very serious damage to the engine, and then it will also cause the engine to be difficult to start, or there will be automatic shutdown of the frequency source nucleus. Such as regression.

The engine cylinder is one of the engine failures, this kind of failure will cause the vehicle exhaust pipe to have a very serious smoke, the power of the engine will also be weakened, and even no power output, there will be abnormal noise, in short, this is a very serious problem, so what are the five reasons for the cylinder?

1. One of the reasons for the engine cylinder pulling is that the quality of the engine oil used is not good, or the fake engine oil is bought, so that the engine oil can not play a normal lubricating effect, which is easy to cause the phenomenon of engine cylinder pulling.

2. If the engine runs at high speed or overload for a long time, it will also cause the engine to pull the cylinder.

3. The lack of engine coolant or high temperature will cause the engine temperature to be too high, and the cylinder pulling phenomenon is also easy to occur when the engine temperature is too high.

4. When the engine lacks oil, the engine will also not be fully lubricated, and the engine will also pull the cylinder.

5. Too much carbon deposits on the top of the engine, or foreign objects entering the generator, will cause the engine to pull the cylinder.

The main reason for the engine cylinder is that the water tank is seriously lacking in lead and the water engine has abnormal high temperature, and it has not been found and dealt with in time. When the piston works up and down at high speed, a large amount of heat is generated and transmitted to the cylinder liner. The abnormal rise of water temperature and poor heat dissipation of the cylinder liner aggravate the expansion of the piston, causing the gap between the piston and the cylinder liner to become smaller and smaller, and finally cause friction.

Pistons, piston rings and cylinder liners are poorly lubricated and cause dry friction. For example, the main oil channel lubricating oil nozzle is blocked or the installation angle is incorrect, and the engine lubricating oil is insufficient.

Engine pulling cylinders, sticking cylinders, etc., are major injuries that require overhaul of the engine。Nowadays, it may be better to overhaul the engine block than to replace the engine directly. Therefore, accidents like this kind generally do not occur in our normal use and maintenance of cars.

However, knowing a little more about the car and its heart that we normally use and rely on will be more helpful for us to use and maintain it properly.

One cylinder of the engine works in much the same way as the syringe we usually seeThere are also cylindrical cylinders and pistons. The cylinder block of the car is made of steel, and although the piston is made of aluminum alloy, it has several piston rings on it, and this piston ring is a steel ring. In the operation, the live Huaifan plugging ring is in close contact with the cylinder block, which can make the combustion chamber in the cylinder completely sealed.

In this way, the strong air pressure generated by the combustion of the oil can push the piston downward.

Pulling the cylinder is due to poor heat dissipation, or poor lubrication, or the air entering the cylinder is not clean, etc., so that there are scratches on the cylinder wall。It is equivalent to a scratch on the inner wall of the syringe tube, which makes a gap between the piston and the tube wall, and such a syringe may not be able to inject water columns. When the cylinder appears, the air tightness of the combustion chamber is not good, and the power output of the engine decreases.

Severe overload in the car, long hours of heavy load work. It is easy to cause piston fatigue fracture and cause cylinder pulling.

When the piston is wide and the piston ring is reciprocating in the cylinder, the cylinder is forcibly pulled out of obvious scratches and grooves due to poor lubrication or too small mutual clearance.

It means that the piston ring in the engine cylinder has longitudinal scratches or scratches on the cylinder wall due to the lubricant, and the friction inside is relatively large when it is active.

The boiling is the cooling of the engine, which may be due to a lack of water or a leak in the closure, or the fuel consumption is too large, or it may be an overloaded operation.

What about the engine pull rod, it refers to the piston ring, or the piston is produced between the cylinder wall, the abnormal wear and tear, and once the phenomenon of the pull rod occurs, this also means that the engine is not far from this overhaul, the cost is not low, today, let's talk about it, what are the reasons for the pull rod?

The first one, is the lubrication abnormality, the main reason is that there are two reasons, the oil is insufficient, or the use of inferior oil, the oil is not enough here we don't need to say more, when we are free, we can take a look at the oil dipstick, check the amount of oil, today we focus on it, this inferior oil, earlier there were some bad merchants, they will use the oil, filter, and there is refining, and then, it's **. What about these oils, the performance has been greatly reduced, the engine lubricator is not good, but this kind of oil, in the market has been relatively rare, now we don't have to worry too much, at present, change the oil, this is more common, that is, the poor performance of the oil, loading this is better, this oil in the bottle, and then, in ****, in general, it is difficult to see the abnormality in the short term, but because of this kind of meat life, it is relatively short, and then, After a period of use, it will cause damage to the engine, but the probability of pulling the cylinder caused by the change of engine oil is still relatively low.

The second is that the water temperature is abnormal, when the engine water temperature is too high, the dashboard will have a reminder, at this time, if you continue to drive, it will cause the engine to produce internal parts. Thermal deformation, and then abnormal wear, of which the pull cylinder is one of the phenomena.

The third is that there are foreign bodies in the cylinder, many people will think that these foreign substances are chicken carbon, but I am not very sure about the hardness of these eggs on the impact of piston movement, uh, but if you use inferior oil bitumen, it is very likely that the impurities in the oil will not be filtered very fully or the AB bitumen machine has been blocked, so that this blind air valve is opened, causing the machine to participate in the lubrication without filtration, and the impact on the moving parts inside the engine can be imagined.

The fourth, is frequent detonation, detonation it refers to the mixer in the cylinder, at high temperature and high pressure has not, uh, that is, when ignition, it has already begun to burn, which will make the piston movement produce a transverse force, so that the piston ring and the cylinder wall between the chaos of the air knocking, then over time, it will pull the steel, but we add the car, don't worry too much, mainly in some modified cars, because this part of the modified car, it is excessive squeezing power, The ignition time is advanced and so on, so if it comes to power modification, we can be cautious, and install it, when we usually maintain the car, we should use the oil of the regular channel, as well as the oil bitumenator, in fact, it is necessary to be cautious about the modification.
