AirPro Densimeter for Optimizing Combustion in Two-Stroke and Four-Stroke Engines.

Standard engineering charts clearly demonstrate how air temperature and barometric pressure impact engine power output. Maximum engine power is directly proportional to “air density,” provided the fuel/air ratio remains consistent. If the fuel/air ratio becomes too rich or too poor, the reduction in power output is significantly greater.

what does air density indicate?

In technical terms, air density represents the amount of air mass present per unit of volume in a given environment. It is influenced by three main factors:

• Atmospheric Pressure: Higher atmospheric pressure compresses air molecules, increase density.
• Air Temperature: Higher Temperature expand air molecules, reducing density, while lower temperature increase it.
• relative Humidity: Humid air is less dens than air dry.

Air Density in Motorsport

Is a critical parameter because:

• It determines the amount of oxygen available for combustion in engines.
• It directly affects carburetion and the air-fuel ratio, which in turn impacts engine power.
