What are the dangers of using inferior gasoline on motorcycles?

The consequences of using inferior gasoline for motorcycles are that they will not catch fire directly, run weakly, sound different, damage the life of the engine, poor anti-knock ability of inferior oil, damage the piston rings of engine parts, if it is gasoline with a lot of impurities, it cannot be completely Combustion, carbon deposition or entering the cylinder to accelerate the cylinder block piston piston ring abnormal wear, small explosive force leads to small work, naturally increase fuel consumption, accelerate the wear of all wear parts of the motorcycle, it doesn’t matter if it affects the riding mood, the point is to threaten life Safety.
1. Maintenance case of motorcycle using inferior gasoline: After hearing a crisp knocking sound when the motorcycle is started, the motorcycle can no longer be started. The valve cover is removed for inspection, and it is found that the clearance of the intake valve suddenly increases. The top of the valve is bent, and the cylinder head is removed to find that the intake valve cannot be closed normally. When the intake valve is removed, it is found that it is covered with a lot of colloid and particles, and a lot of colloidal particles are also attached to the intake port.
2. This is the impurities in the released gasoline tank. Look, it's shocking enough, these gums are fine when the engine temperature is high, they just have some blocking effect, but once they accumulate too much and the car is cold, they will stick the valve and cause inflexible movement, causing the piston Hit the valve, causing a serious failure.
3. How to choose a gasoline model for a motorcycle? Many people think that motorcycles can add 95 gasoline, at least there is no harm, but if it is a car with a low compression ratio, such as a compression ratio below 9.5:1, just add 92 gasoline, there is no need to add 95 gasoline. Yes, the level of the gasoline grade does not mean the quality of the oil or whether it is clean or not, but to be adapted to the engine compression ratio. Blindly increasing the grade of gasoline is useless and beneficial. What kind of gasoline is added to the motorcycle , depending on the compression ratio of the car's engine, the general engine compression ratio above 9.5:1 is suitable for the use of 95 gasoline.
4. For motorcycles with a relatively low compression ratio, it is useless to increase gasoline. For ordinary motorcycles, there is no difference or obvious difference in using 92 or 95 gasoline. Unless the compression ratio is relatively high, it is not necessary. With high-grade gasoline, the compression ratio is a very important concept in the engine. The compression ratio indicates the degree of compression of the gas. It is the ratio of the volume of the gas before compression to the volume of the gas after compression, that is, the total volume of the cylinder and the volume of the combustion chamber. The ratio is called the compression ratio.
5. Usually the compression ratio of a gasoline engine is 6-10. The engine can maintain a stable and appropriate compression ratio to make the engine run smoothly and stably. At present, most of the cars use the so-called 'reciprocating engine'. Simply put, in the engine cylinder, there is a piston that reciprocates in a straight line. There is a certain range of motion in the stroke.
As far as a cylinder of the engine is concerned, when the stroke of the piston reaches the lowest point, the position at this time is called the bottom dead center. The volume formed by the entire cylinder including the combustion chamber is the maximum stroke volume. When the piston moves in the opposite direction, it reaches the bottom dead center. When the highest point is at the position, this position is called the top dead center, and the formed volume is the smallest volume of the entire piston movement stroke. The compression ratio to be calculated is the ratio of the maximum stroke volume to the minimum volume.
