What is the effect of bad motorcycle oil on the engine?

There is an effect that burns the engine oil.

It means that the engine oil enters the combustion chamber of the engine through a certain way and participates in combustion together with the mixture. This is mainly due to a cylinder leak caused by damage to the piston rings, and oil escapes into the combustion chamber. It is recommended to carry out maintenance as soon as possible, if this is the case in the long run, not only will the oil consumption be large, but also the impurities generated by the combustion of the engine oil will cause carbon deposits in the combustion chamber.

, which in turn affects engine performance.

There are two causes of engine oil burning:

1.Normal wear and tear, that is, the normal phenomenon of a vehicle after a certain number of kilometers.

2.Abnormal wear and tear: The cause of abnormal wear and tear is early wear caused by product quality and improper use.

Engine oil is very important to the engine, just like the blood of machinery, if the oil is not good, it will increase the wear and tear of the engine, premature wear or damage to parts, shorten the service life of the engine, and there may be noise, power decline and other failures.

The main role of motor oil in motorcycles is as follows:

1. Lubrication and wear reduction: between the piston and the cylinder, between the spindle and the bearing, there is a fast relative sliding, to prevent the parts from wearing too quickly, it is necessary to establish an oil film between the two sliding surfaces. An oil film of sufficient thickness separates the surface of the relatively sliding part to reduce wear.

2. Cooling and cooling: The oil can bring the heat back to the oil tank and then dissipate it into the air to help the water tank cool the engine.

3. Cleaning and cleaning: good engine oil can bring carbide, sludge and wear metal particles on the engine parts back to the oil tank through circulation, and wash the dirt generated on the working surface of the parts through the flow of lubricating oil.

4. Sealing and leak-proof: The oil can form a sealing ring between the piston ring and the piston to reduce gas leakage and prevent external pollutants from entering.

5. Anti-rust and anti-corrosion: lubricating oil can be absorbed on the surface of parts to prevent water, air, acidic substances and harmful gases from contacting parts. 6. Shock absorption and buffering

When the pressure of the engine cylinder port rises sharply, the load on the piston, piston chips, connecting rod and crankshaft bearing is suddenly aggravated, and this load is transmitted and lubricated by the bearing, so that the shock load is cushioned.

Therefore, the quality of the engine oil condition directly affects the performance and life of the engine, so we must choose the appropriate brand oil and replace it in time.

The wear of transmission mechanisms such as cylinders and crankshafts accelerates, fuel consumption rises, and power decreases. It is recommended to buy a better oil, and the expensive part of the money can be saved from the maintenance costs and fuel costs in the future.

If the motorcycle oil is low, the friction between the parts in the machine will increase, and it will wear out excessively over time, which led to a strike on the machine. With the addition of engine oil, it will have a lubricating effect, which can reduce the smoothness and deterioration caused by the friction of the internal parts of the locomotive.

Running out of oil on a motorcycle will cause the engine to overheat, and it will also cause engine pistons, cylinders, and crankshafts.

Rocker arms, camshafts.

A series of mechanical wear and tear damage the service life of the engine, and even damage the crankshaft and cylinder block in serious cases, resulting in piston locking, and eventually leading to the scrapping of the engine.

The engine is hot and easy to stall. If the engine overheats, it will damage the life of the engine. In a short period of time, due to the lack of lubrication, there will be serious wear of pistons, cylinders, crankshafts, rocker arms, camshafts and other parts, and the severe grinding of the mold is even locked, resulting in the scrapping of the engine.

Two-wheeled four-stroke motorcycle new car maintenance knowledge:

1) The first time: the new car needs to change the engine oil at 300 kilometers (the new car oil is provided by the seller);

2) The second time: change the engine oil when the motorcycle is running 600 kilometers;

3) The third time: change the oil at 1000 km, this is the first three times, maintenance is very important.

After the first three maintenances, the maintenance is carried out every 500 km, which makes the bike last longer.

1. If the engine oil is added too much, the volume will expand after the car runs hot, which will cause the pressure of the oil chamber to increase, the running resistance to increase, the engine to produce high temperature, the power to decline and the clutch to be separated incompletely.

2. There is a lot of oil, the crankcase has a vent pipe, and adding more oil will cause a string of oil, and the pressure of the crankcase is large, and the oil seals on the crankcase are easy to be caused by such a high oil pressure. In addition, it also affects heat dissipation, and the resistance of the crankshaft is also large, which increases fuel consumption.

3. If the pressure is high, there will be oil leakage from the oil seal or snorkel pipe, etc., and too much oil may even enter the combustion chamber, and blue smoke will be formed from the exhaust pipe after combustion, resulting in the illusion of burning engine oil.

4. When the engine oil is injected too much, the flow resistance of the oil inside the engine increases and the gas pressure inside it increases, forming a reaction force that consumes the output power of the engine.

5. The oil is easily discharged from the air pipe or carburetor air port, and the air filter connected to the engine ventilation pipe may run to the air filter if the oil is added, resulting in insufficient air intake affecting combustion, and then affecting power and fuel consumption.

If the oil is added, the pressure in the crankcase will be increased, and it will be difficult to start the brake, so that the oil will run up to the combustion chamber.

du, increase pistons, valves, zhi exhaust dao

carbon deposits of pipes, etc.

There are two places where the oil can be drained, one is in the left crankcase, and there is a copper-colored screw with a 17-gauge sleeve under the lid of the belt box (gearbox, which is the foot start), and there is a spacer.

The other is at the bottom of the right crankcase, which is the bottom of the oil dipstick and the oil hole, and there is also a cover to use the No. 17 sleeve, which has a spring and oil filter inside after the cover is opened, which is the oil outlet hole for each maintenance.

If you want to add oil, you should add it from the oil dipstick and the oil hole of the dipstick, and add it to the middle scale line of the dipstick.

The small chain is loose, and the small chain tensioner is adjusted to the small chain without relaxation

1. Engine oil.

Too much, it is easy to soak through the piston ring, and the oil enters the combustion chamber and burns the oil.

2. There is too much oil in the engine, the resistance capacity of the internal parts of the engine is too large, the internal consumption of the engine increases, and the power decreases.

3. Burning engine oil will form a large amount of carbon deposits, which will affect the normal opening and closing of the valve and the normal operation of the engine.

4. Carbon deposits enter the engine oil, accelerate the deterioration of the engine oil, and shorten the replacement cycle.

Adding too much oil will cause the oil to burn.
