Nettet1. sep. 2006 · As currently used, the terms “pressure differential,” “MAP” and “intake manifold vacuum” refer to the difference between atmospheric and intake manifold pressures. Atmospheric pressure is about 14.7 pounds per square inch of pressure at sea level. Atmospheric pressure at sea level will also support a column of liquid … NettetIf the intake manifold pressure measured by the system deviates from the set-point value, the actual value must be checked using a separate vacuum manometer. If the … Nettetp im - intake manifold pressure, r - engine compression ratio. K i - intake manifold air temperature correction factor takes into account heat transfer from the intake manifold wall to the intake air. The baseline condition is 330 K (57°C). Higher intake air temperature means less heat is transferred from the hotter intake manifold wall. how to search for jobs online
