The formula to calculate the Engine Mass Air Flow (EMAF) is:
\[ EMAF = ATF \times FF \]
Where:
Engine Mass Air Flow (EMAF) is a measure of the total mass of air that passes through an engine per unit of time. It is typically measured in pounds per hour and is a critical parameter in engine performance and tuning. By knowing the mass air flow, engineers can optimize the air-to-fuel ratio, ensuring efficient combustion and maximizing engine performance.
Let's consider an example:
Using the formula to calculate the Engine Mass Air Flow (EMAF):
\[ EMAF = 14.7 \times 100 = 1470 \, \text{lbs per hour} \]
This means that the engine is passing 1470 pounds of air per hour through the engine at the given air-to-fuel ratio and fuel flow rate.
