Recently, I feel that the power of the car is a little insufficient and the acceleration is weak. Step on the gas and you won't feel much power. Ask the experts to point out the reasons.

Adding an inappropriate fuel label (for example, adding 93 to 90) will cause the output power and power of the automobile to decrease, or the fuel tank switch, fuel filter and fuel pipeline between the fuel tank and carburetor are partially blocked due to the blockage of the vent hole of the fuel tank cover, which can not meet the required fuel supply, resulting in too thin mixture and weak engine acceleration.

Insufficient engine oil, engine coolant, engine radiator failure, etc. It will increase the load of the engine and even lead to poor heat dissipation of the engine. Engine overheating will cause poor lubrication effect, increase mechanical wear, reduce engine power, and lead to engine acceleration weakness.

Precautions:

1, pay attention to prevent fatigue driving: fatigue causes the driver's judgment ability to decline, slow response, and increased operational errors, which leads to untimely and inaccurate gear shifting, and some even fall asleep for a short time and lose the ability to control the vehicle. Therefore, when the driver feels tired, he should leave the road in time, stop at a safe place to rest, and then continue driving after reducing fatigue.

2. Don't drink and drive: After drinking alcohol, the blood alcohol concentration will increase, leading to paralysis of the central nervous system, decreased rationality and self-control, decreased vision, narrowed vision, inattention, and weakened sense of body balance, which leads to the driver's slow response and slow action when manipulating the brake, acceleration and clutch pedal. According to the laws and regulations of China, it is forbidden to drive a motor vehicle after drinking.

3. There are many dangers of speeding: when speeding, the driver is nervous, consumes a lot of psychological and physiological energy, reduces his vision, narrows his vision and deteriorates his judgment ability, which directly affects the driver's operational stability. In an emergency, drivers are often caught off guard and prone to traffic accidents such as collision and rollover.
