1. Reasons for fuel supply system:
Because the vent hole of the fuel tank cover is blocked, the fuel tank switch, fuel filter and fuel tank are all connected to the carburetor.
The oil pipe between pipes is partially blocked, which can not meet the required oil supply, resulting in too thin mixture and weak engine work.
2, the cause of the ignition system:
Inappropriate ignition timing and premature ignition lead to premature combustion and detonation of combustible mixture. Due to the ignition system
Spark plug failure leads to spark plug fracture or weak spark plug.
3. Compression pressure of cylinder:
The serious wear of piston, piston ring and cylinder leads to the increase of fit clearance between piston, piston ring and cylinder.
Coupled with the poor sealing performance, the cylinder head leaks air and reduces the compression pressure of the cylinder.
4, engine overheating:
Incomplete combustion of combustible mixture due to various reasons leads to excessive carbon deposition in the combustion chamber.
It leads to poor heat dissipation and overheating due to the increase of engine load.
5, lubricating oil problem:
Too much or too little lubricating oil in the crankcase will deteriorate or become dirty, blocking the lubricating oil passage and affecting the power of the engine.
Conduct targeted investigations and solutions.

Daily maintenance of automobile use:
First, the maintenance of automobile engines
Car engines should be cleaned at the right time. Because long-term use will form a thick layer of carbon deposit on the engine surface, which will have a great corrosive effect on the rubber parts in the engine.
Second, we should prevent gasoline and water from evaporating.
In summer, the temperature is generally higher. So gasoline and water evaporate more easily than usual. Because the water tank and oil tank should be checked frequently, gasoline and water should be added in time when there is little.
Third, pay attention to hygiene in the car.
Summer is the fastest season for bacteria to multiply, so it is necessary to keep the car clean, especially the car seat cushion, steering wheel cover and car mat.
Fourth, the car wiper should be replaced.
When driving in rainy days, be sure to pay attention to the wiper. The rubber sheet on the wiper will age for a long time. In order to have a better driving sight when driving in rainy days, it is best to replace the wiper once every two years.
Fifth, the car mats should be updated.
Good automobile cooling pad is an important choice for automobile sun protection in hot season. Choose a cool mat that is not too slippery. In order to avoid slipping while driving and causing traffic accidents.
Sixth, the body should also be maintained.
Ultraviolet rays are also very harmful to cars, such as the penetration of car paint. You may notice that after a white car has been exposed to the sun for a long time, the color of the car body will obviously turn pale and yellow. Therefore, waxing and polishing your car in summer can protect your car.
