Why do cars have better power on rainy days than on sunny days?

The power, engine running smoothness and sound of the crown block in rainy days are better than those in sunny days, and it is particularly comfortable to drive. The analysis may be the following reasons: 1. The air humidity increases in rainy days, which makes the automobile engine work in the best state.

2. The pressure change and air density in rainy weather make the engine sound transmission and exhaust pipe sound attenuation better.

3. In rainy days, the conductive effect of automobile circuit contacts is improved, which makes the engine ignition voltage close to the design index and the gasoline burns fully.

4. Because there is no obvious difference in engine power between summer and winter, I feel that it has nothing to do with the temperature in rainy days.

Matters needing attention when driving in rainy days:

1. Keep the distance between cars: The sight of driving in rainy days is blocked, and the distance between two cars is not accurate as usual, so it is necessary to keep a large distance from the car in front.

2. low-speed driving: the road surface is slippery in rainy days, which suddenly stops when driving at high speed.

3. Turn on the fog lights in rainy days: In foggy weather caused by rainy days, it can be seen that the driving insecurity caused by the narrowing of the visual field increases rapidly.

4. stay away from large trucks and trucks: stay away from large trucks when running at high speed. When driving in rainy days, in case of sudden situation, large trucks basically can't stop.
