The engine performs better in the rain: a scientific explanation for the unexpected effect

According to hvylya.net: During rain, the operation of a car engine can change noticeably, and this effect has a scientific explanation. In humid air, the concentration of oxygen and water vapor increases, which affects the combustion process of the fuel-air mixture.

Igor, a motor technician from Kyiv with over fifteen years of experience, explains: 'The air in the rain is saturated with water vapor, which brings additional oxygen into the engine. As we know, oxygen is a key factor for complete fuel combustion.'

This ensures a more complete and faster combustion of the mixture, increasing the engine's efficiency, making its operation more stable, and reducing jerks during movement.

The humidity effect and the risk of detonation

High humidity reduces the risk of detonation, helping to preserve the engine's lifespan. The electronic control unit in modern cars quickly adjusts the fuel-to-air ratio considering the humidity of the air.

At the same time, it is worth remembering that better dynamics during rain may indicate malfunctions in the fuel system or other issues, so in dry weather, it is important to ensure the engine operates stably.

In humid air during rain, the concentration of oxygen and water vapor increases, positively affecting the performance of the car engine. This helps increase the efficiency of its operation and reduce the risk of detonation, but it can also indicate problems in the car's fuel system in dry weather.
