What to do if a motorcycle burns engine oil What happens when a motorcycle burns engine oil and how

Burning engine oil is generally caused by the wear of the cylinder block, piston, piston ring or valve oil seal is not tightly sealed, disassemble the engine for maintenance, replace the problematic parts according to the situation, if it is the cylinder block and piston and piston ring caused by the burning of engine oil, it is best to replace the whole set of parts, sometimes the single replacement piston ring may not be very good, and the oil will be burned soon after, but if only the piston ring has obvious wear, the condition of the cylinder block and piston is very good, and it can not be replaced. If there is obvious oil stains on the back of the valve seal, but the cylinder block and piston ring are not obviously worn, and the piston ring opening clearance is not significantly too large (generally not more than millimeters), only the valve oil seal needs to be changed.

Don't change so much, the best is only two hundred packs to change the oil, at that time I changed a set, he wants so many obviously kill you, remember to change all when you change, and the valve, and you said resolutely 200 or go to other stores, the bad 160 have been changed, because my friend and I have changed. After changing it, remember to change the oil again in a week to half a month, because you are the new power.

It's the fate of the scooter to burn oil, so you can imagine how difficult this problem is to solve. To confirm whether the engine oil is burned, you only need to look at the oil consumption to confirm it. However, the smoke you mentioned, coupled with the weak acceleration, this is not necessarily, it may be that the air filter is blocked, the mixed steam caused by the large intake resistance is too thick, or it may be the leakage of the gas distribution mechanism and the incomplete combustion caused by the reduction of the compression ratio.

In short, your scooter has reached the stage of middle and old age (this is not determined by time, it depends on the condition of the car).

Is that okay?

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.

Reasons why motorcycles burn engine oil:

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;

3. The size of the cylinder is poor, 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.

Motorcycle Composition:

1. Engine: The engine is a two-stroke or four-stroke gasoline engine. It adopts air-cooled cooling, and there are two types: natural air-cooled and forced-air-cooled.

2. Transmission system: The transmission system of the motorcycle includes several parts, such as primary deceleration, clutch, gearbox, and secondary deceleration.

3. Walking system: The function of the walking system is to support the weight of the whole vehicle and the load, and ensure the stability of the operation and the comfort of the ride. The travel system mainly includes frame, fork, front shock absorber, rear shock absorber, wheels, etc.

4. Steering and braking system: the front wheel and the handlebar cooperate to control the driving direction of the motorcycle. The handlebar is installed on the upper coupling plate, and when the handlebar rotates around the direction column, the upper and lower coupling plates rotate accordingly, and the front wheel is driven to rotate left and right by the front shock absorber.

Generally, the front wheel brake is controlled by the hand knob, and the rear wheel brake is completed by the foot brake pedal.

The only solution to eliminate the fault of motorcycle oil burning is to replace parts.

Because the oil is mainly caused by the damage of the parts, it is divided into normal wear and tear and human factors, when the parts are repaired and replaced, they can be replaced according to the wear state of the parts, usually the oil is slightly burned to replace the piston, the ring failure can be solved, if the cylinder block is pulled, it is necessary to replace the cylinder assembly, valve oil seal and other supporting parts.

Characteristics of the oil.

The engine is the heart of the car, and there are many metal surfaces in the engine that rub against each other, and these parts move fast, the environment is poor, and the operating temperature can reach 400 to 600 meters. The new technology transforms natural gas into crystal-pure, fully synthetic base oils, on which is added with unique powered cleaning technology to create lubricants with superior cleaning protection.

Under such harsh working conditions, only qualified lubricating oil can reduce the wear of engine parts and prolong the service life. The engine oil on the market can be divided into two types: mineral oil and synthetic oil due to its different base oils (vegetable oil is not counted due to the scarcity of production).

Synthetic oil is divided into: fully synthetic and semi-synthetic. Lubricating oil base oils are mainly divided into two categories: mineral base oils and synthetic base oils. Mineral base oils are used in a wide range of applications in large quantities (about 95% or more), but some applications require the use of synthetic base stock blends.

The piston rings are badly worn.

Poor sealing. The oil seeps into the combustion chamber and combustion, which is what is called burning oil.

It's time to change the piston rings

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

If you find that the oil is burningHere's how to deal with it:

1. Go to the repair shop to replace the aging oil seal and rubber ring.

2. Go to the repair shop to replace the cylinder block and piston.

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.

If the cylinder head burns oil because the valve guide is worn and there is a gap, the oil leaks into the combustion chamber or the valve oil seal is aging, and the sealing degree decreases, causing the oil to flow into the combustion chamber. If the piston is worn too much and the oil seal is seriously aged, the oil can be replaced.

Precautions for burning engine oil.

1. Pay attention to the cleanliness of the fuel oil circuit: carbon deposition is essential in the combustion process of fuel, and carbon deposition is the root cause of some automobile failures, such as the aging of valve oil seals, the increase in piston wall clearance, etc., which are directly or indirectly related to the formation of carbon deposition, so keeping the fuel oil circuit clean is of great help to prevent burning engine oil, of course, this needs to be done with the help of high-quality fuel additives.

2. With the help of external forces: as mentioned above, the cleanliness of the fuel oil circuit and the anti-aging degree of the engine oil are basically the key to determining whether the engine oil can be prevented, so considering the relationship between domestic oil products, it is necessary to use high-quality engine oil and fuel additives to achieve, which is also the key to solving the problem of burning engine oil without dismantling and repair.

Hello, I am helping you sort out the answers to your questions, please wait a while Hello, motorcycle engine oil is generally divided into two kinds of engine oil, the first is the valve, and the piston ring burns the oil, do not disassemble the engine, replace the piston ring and valve oil seal.

Question: How to repair the motorcycle because it burns oil very badly.

Question: I changed a bottle of engine oil last time, it should only be able to run 60km, and if you answer this phenomenon, you can only overhaul and replace the piston rings and valve seals, and ask whether the engine will have other effects after dismantling.

This is the case of my car, if you change a bottle of oil, you can only run to 60 70km and there is no oil, is it good to change the piston ring oil seal and valve.

The answer to this depends on your local cost, usually about 200 yuan, question: Can I ride with a bottle of engine oil now? The car is 20 kilometers away from home, and there is a Xiuli shop to answer yes.

1. Look at the exhaust pipe, if the exhaust pipe mouth is wet, and there is blue smoke coming out after the vehicle starts, then it is basically certain that there is a phenomenon of burning engine oil.

2. Oil consumption, if the oil just added is not available in two days, or the consumption of lubricating oil is relatively fast, it can basically be judged that the vehicle has the phenomenon of burning engine oil.

3. Spark plugs, if the spark plugs are often damaged during the use of motorcycles, and the electrodes of the spark plugs are relatively black or oily, it is basically the performance of burning engine oil.

Determine whether the motorcycle burns engine oil.

1. It can be judged from the oil consumption of the motorcycle, if the oil consumption is very fast, it is the oil burned. The new car you just bought will not burn the engine oil, so you can judge according to your previous oil consumption, if the current oil consumption is significantly greater than the previous oil consumption, then, it is likely to burn the engine oil.

2. It can be judged from the smoke exhaust of the exhaust pipe, if there is obvious blue smoke or black smoke in the exhaust pipe during driving, or there are many black sticky substances at the outlet of the exhaust pipe, and the consumption of engine oil is obvious, then it can be basically determined that the engine oil is burned.
