The engine of the Prince motorcycle is high temperature and burns oil

This is also a scoring situation, generally said that repairs do not work, because there are generations when damaged. For example, the lack of oil pull cylinder, some serious piston pins have been burned and glued to the connecting rod, if knocked off, the connecting rod is basically unusable (it belongs to the crankshaft assembly). At this time, if it is not forcibly used, the piston and cylinder behind it will not have the original effect, and it will be particularly easy to break.

Another example is to drop the chain and knock off the left cover, some models will also break the magneto base at the same time, and replace it with a new one, often without the parts in the factory, and the seals are not as good as the original, so they rely on glue to seal. The colloid itself has a thickness, which also affects the heat conduction. At the same time, the repair shop does not have special tools in the factory, so there is no guarantee that it can be repaired back to the original performance!

Including changing the small chain and the guide tensioner around the chain, changing the friction plate of the clutch, and changing the reset torsion spring of the starting lever, etc., all of which often occur, but they will also be caused by the fact that the quality of the parts is not as good as the original, and there are successive generations when damaged.

Burn the oil to replace the cylinder block, piston, piston ring and valve oil seal, the cost is generally between 200 300 yuan, the sound problem can not be heard and it is not good to judge the stickiness, the abnormal sound of the scooter, mostly from the valve clearance, valve rocker arm and camshaft wear, timing chain lengthening or tensioner failure, cylinder piston strain, etc., the sound problem can not be heard and judged badly. The engine is not very cost-effective, the engine of the first class is generally not bought, and it will be very expensive to buy (about 2000 yuan), and most of the engines that can be bought are inferior goods, so it is better to repair the original one.

Repair the engine to see the repair of the **, if the piston and barrel are replaced, this is a major operation, the new cylinder barrel piston is not as good as the factory assembly, the quality is to be discounted, if the clutch is repaired, the engine quality has little impact. In fact, motorcycle engines are not complicated, and they have reached the level of repairing the engine, which either means that the overall quality of the engine is not very good, or it is used improperly. It can only be said that it can be used, but it is discounted compared to the normal engine.

The repaired machine should be run-in, and the new car is the same, it is very important to have a good run-in process, which is related to the durability of the problem of whether it can be durable, the run-in is not good and generally will not be durable, or there will be problems earlier, high temperature, component problems, maintenance status problems, will cause high temperature, after low-speed running-in, it will generally be alleviated, and the more you use it, the better, as for the burning of engine oil, there are excellent accessories, suitable matching clearance, good maintenance technology, can ensure that there is a very good state after running-in, supplementNot all components can be loaded directly, to check and test, to have maintenance technology to ensure that this is different maintenance workers do not do the same work

The temperature of the motorcycle engine is too high, especially in the summer.

Causes of motorcycle engine overheating: 1. The engine overheats due to long-term overload or working at high power. 2. The engine is overheated due to poor heat dissipation.

3. Overheating due to inappropriate fuel mixing ratio. 4. Overheating due to improper use of gasoline. 5. Overheating due to inappropriate concentration of combustible mixture.

6. Overheating due to too early or too late ignition time.

The main reason for the excessive temperature of the motorcycle engine.

The temperature of the motorcycle engine is too high, especially in the summer. When someone touches the engine with their hands, they feel very hot, and they think that the engine temperature is abnormal. In fact, it may have something to do with the weather.

The solution to burning engine oil for motorcycles:

1.Generally speaking, motorcycle oil burning is caused by many situations. It may be the aging of the oil seal, the oil seal is not tight due to the aging of the rubber for a long time, and so on.

In this case, the phenomenon is that there is black smoke produced as soon as the motorcycle exhaust pipe is started, and the solution is to go to the repair shop to replace some of the aging parts mentioned above.

2.It is understood that in the process of motorcycle driving, the cylinder block and piston are to run at high speed, and the consumption of gasoline is converted into kinetic energy output. Therefore, if the cylinder and piston are worn out for too long, it will also cause oil to flow into the combustion chamber of the cylinder.

Then, at this time, the engine oil will be burned and consumed, and the solution is to replace the cylinder block and piston.

3.Generally, the above two situations are the case of motorcycle oil burning, and there is also a situation that the cylinder block is not tightly sealed, and the oil on the chain runs into the cylinder block when driving, resulting in oil burning. This happens very rarely, and generally not more than considered.

Motorcycle engine oil burning is a relatively common fault, which is caused by the large gap between the piston ring and the contact surface of the cylinder block, and the oil enters the combustion chamber. The main lubrication of the cylinder block is done by pressure splashing, while the main function of the piston ring is to scrape away the excess lubricating oil from the cylinder wall. Once the piston rings are worn too much, they cannot scrape off excess oil from the cylinder walls.

Motorcycle oil burning is nothing more than the piston, piston ring or cylinder wall is seriously worn, and the sealing is not good when working, causing the oil in the crankcase to string into the cylinder and burn together with the mixture.

There is also a situation that the valve guide oil seal of the intake and exhaust valve is aging or damaged, resulting in the oil stringed from the oil seal to the cylinder will also cause the oil to burn, first to find out which situation is, if it is caused by the valve guide oil seal, you can replace the oil seal can be solved, if the piston ring is worn, then replace the piston ring or cylinder wall, if there are conditions, you can also bore the cylinder, replace the piston piston ring of the boring cylinder expansion model, so the cost should be smaller.

You can try the following steps to solve the problem of burning engine oil on motorcycles:

1. After burning the engine oil on the motorcycle, first check whether the engine is leaking. The engine is just under the saddle of the motorcycle.

Second, if it is an engine oil leak, this needs to be repaired. If it's not the fault of the engine, we'll test somewhere else.

3. Set the motorcycle on fire. Hang the gear in Gear 0 and hold up the footrest. Turn on the throttle to the bottom. Look at the color of the smoke coming out of the exhaust pipe. If it's a blue face, it's likely that there is a problem with the piston ring or piston.

Fourth, the piston ring and piston need to be replaced. The general way to burn engine oil is that both of these need to go to a motorcycle repair shop for repair and replacement.

Generally, the oil is burned by the piston ring is seriously worn, and it is enough to change a set of rings, and there are generally two parts of the oil burning: one part is the cylinder block, and the other part is the cylinder head. There are also several situations in which the cylinder burns engine oil:

One is excessive wear of the cylinder barrel, and the other is excessive wear of the piston or failure of the piston ring. When the cylinder barrel is worn too much, and the dead center of the piston forms a "table", there is also uneven wear of the cylinder barrel, and when the driving cone or ellipse, the oil replaced by the piston ring will accumulate and participate in combustion; When the piston is worn too much or the piston ring loses its elasticity after long-term use, the sealing is not tight, and too much oil is brought into the combustion chamber to participate in the combustion, which will also form oil burning. The cylinder head burns oil because the valve guide is worn and the gap is formed, the oil leaks into the combustion chamber and/or the valve oil seal is aging, and the sealing degree decreases, resulting in the oil extending the valve and flowing into the combustion chamber.

When the engine oil is slight, you can roughly judge the fault location by observing the exhaust: if the engine oil is burned when the car is cool, it is most likely the valve oil seal, and if the car is hot and the oil is burned, it is most likely the piston or piston ring. When the oil is burned severely, it is difficult to judge whether the cylinder block or the cylinder head burns the oil, the engine must be disassembled for inspection, and sometimes the piston must be poked out of the cylinder barrel, and the roundness and taper of the cylinder barrel must be measured with an inner diameter micrometer.

What causes motorcycle oil burning? As long as you do these things, the motorcycle will never burn the oil.

Motorcycle burns engine oil because the oil is mixed with the combustion chamber and gasoline, which is manifested as blue smoke from the exhaust cylinder, [you can diagnose yourself, support the big frame, increase the oil to see the exhaust pipe smoke] In fact, the amount of channeling is very small and negligible, unnecessary maintenance, when the spark plug is frequently damaged, it must be replaced, resulting in the burning of the engine oil parts are valve oil seals, piston rings, piston rings, piston rings are wearing parts, cylinder blocks and pistons are generally not easy to damage, some maintenance unions say that your cylinder and piston piston rings are all damaged, In fact, 80% of it is fraud, and even when you leave, he will take some scrap parts that have been repaired before to show you that it is yours, replace the invisible parts and don't leave, try to repair in a motorcycle shop, often replace the repair shop, basically every time will deceive you.

Generally speaking, the oil burns because the cylinder liner, piston, and piston ring are worn too much, resulting in poor sealing. When the piston descends to make a suction stroke, the oil attached to the cylinder wall is injected into the cylinder, forming a "burn oil".

Replace the piston rings. If the wear is severe, the cylinder is bored, and the piston and piston ring are replaced.

The piston ring and cylinder barrel are worn unevenly, and there is a gap, which causes the oil to enter the combustion chamber and burn the engine oil, which is generally to change these two and do not need to be otherwise.

According to your description, this kind of problem occurs mainly because the engine has been in time for a long time and the parts are aging, and it is recommended to overhaul the engine.

How to repair a motorcycle when it burns oil.

The main reasons for burning engine oil in motorcycles:

1. The elasticity of the piston ring oil ring is too small, and the light leakage is too large, which leads to the burning of the engine oil, which is the reason for the piston ring itself.

2. The gap between the valve stem and the valve guide is too large, and the valve oil seal is not strict, and this phenomenon of burning engine oil has nothing to do with the piston ring, and the piston ring is still burned after replacing the piston ring.

3. The size of the cylinder is out of tolerance, the ellipse is too large, and there are strains and grooves on the surface, so that the oil ring can not scrape off the excess oil on the cylinder wall, and the oil enters the combustion chamber and participates in combustion.

4. The taper of the cone ring is reversed, and the oil is scraped upward, which will also increase the oil consumption.

5. When the piston ring is assembled, the opening position is not staggered, and it is arranged in a straight line, which will make the oil consumption soar.

6. The connecting rod bearing is of poor quality or excessive wear, resulting in piston gluing and overloading of engine fuel consumption.

7. The quality of the cooling system is not good, and the early wear of the piston ring is large due to overheating, and the surface of the ring and the cylinder wall are strained, which makes the engine emit blue smoke. The air filter should be cleaned regularly to make it work normally, to ensure that the engine has good heat dissipation, can not be overloaded for a long time, and after the new piston ring is installed, it is necessary to run the run-in period.

It is best to go to the 4S shop to check to see if it is an oil leak or the engine burns the oil, if the oil is burned, it must be accompanied by a series of problems such as high engine water temperature.

The ring is aging, and the valve oil seal is aging.

Replace the water in the tank with pure refrigerant liquid, do not mix with water, burn the oil because the temperature is too high, and the oil becomes thinner.

The smoke coming out of the exhaust pipe is blue or even gray, and the exhaust port sometimes has an oily substance, and the smoke has a relatively heavy oil smell.

"Burning oil" means that the oil enters the combustion chamber of the engine and participates in the combustion together with the mixture. The phenomenon of "burning oil" in the vehicle will damage the vehicle oxygen sensor too quickly, resulting in an increase in carbon deposition in the combustion chamber, unstable idling, weak acceleration, rising fuel consumption, excessive exhaust emissions and other adverse consequences. In the traffic conditions of frequent starts and stops, many car owners report that their cars "burn engine oil", so it is necessary to understand the hazards, identification and avoidance methods of burning engine oil.

The exhaust pipe is colored when the oil is burned, and the power is not enough! There is a problem with the steel sleeve piston in the engine, or the piston ring, it is recommended that you repair it as soon as possible.

The most obvious thing about burning engine oil in a 4-stroke is the exhaust of blue gas, blue smoke! Pick it up and smell it.

It smells of burnt ugliness!

What causes motorcycle oil burning? As long as you do these things, the motorcycle will never burn the oil.

First, the main reason for burning engine oil.

1. Use engine oil with poor quality or viscosity grade that does not meet the requirements. In addition, too low or too high oil viscosity can lead to poor engine lubrication, increased wear of piston rings and cylinder walls, and reduced sealing performance, resulting in oil burning.

2. The matching gap between the piston ring and the cylinder wall is too large, the piston ring is improperly installed or the sealing is poor, and the oil on the cylinder wall enters the combustion chamber, causing the phenomenon of burning the engine oil; In addition, poor sealing performance of the valve seal, damage to the crankcase forced draft valve (PCV) or crankcase vent blockage can cause excessive pressure in the crankcase to cause the oil to enter the cylinder with the crankcase gas and participate in combustion.

3. Burning engine oil caused by excessive oil filling. When the oil is filled above the center line, the part of the engine lubrication process that passes through splash lubrication will be too much into the combustion chamber due to the high oil pressure.

4. Oil leakage from turbocharger. The turbocharger is mounted at the front of the exhaust pipe and operates at a very high temperature, and the turbine and pump wheels can reach 120,000 revolutions per minute when the engine is running at full load. The turbine shaft has oil-lubricated floating bearings, and the car has one oil passage to the turbocharger.

Oil leaks from pipes or bearings can allow oil to seep from the turbocharger into the exhaust pipe. When the exhaust pipe temperature is high, the oil is baked and discharged into blue smoke.

5. There is leakage in the valve oil seal, which means that the oil leaks into the combustion chamber through the valve oil seal.

Second, the method of preventing the burning of engine oil.

1. Use engine oil that meets the technical requirements of the vehicle. Many car owners never read the vehicle manual, and they don't know what quality and viscosity grade oil their vehicles use for a few years, and there is a lot of arbitrariness in the use of engine oil. When using engine oil, one is to pay attention to the quality index, and the other is to pay attention to the viscosity index.

The quality index refers to the grade above SL as much as possible, and the viscosity index should be strictly in accordance with the provisions of the viscosity index in the automobile manual, and cannot be too low or too high.

2. Avoid frequent rapid acceleration and long-term ultra-high-speed driving. When the engine rotates at ultra-high speed, it is easy to break the lubricating oil film, resulting in poor lubrication and dry grinding of the rotating parts, and when it becomes a regular operation, it will make the engine wear abnormally and burn the oil, therefore, maintaining economic speed is one of the best ways to prevent the phenomenon of burning oil.

3. The oil must meet the specifications when filling. When the oil filling volume exceeds the center line, the repairman should be asked to pump out the excess oil, in addition, the oil volume should be observed before the next day.

4. If you find that the engine oil is burned, go to the maintenance station for inspection as soon as possible. If it is due to engine failure (such as poor piston ring sealing, valve oil seal leakage, cylinder gasket leakage, etc.), you should go to the maintenance station as soon as possible to check and repair the fault as soon as possible.
