Manifold Absolute Pressure in Engine Simulations

Hi guys,
So I am trying to simulate a 4-stroke engine (cold flow) with moving valves and piston. From the specifications of the engine I get that the MAP (Manifold Absolute Pressure) is 46 kPa. So I am no expert, and don't really know what this would mean, but I read it is the difference in pressure between the pressure in the manifold (intake I guess) and the atmospheric pressure. So I guess my questions are: Should I specify a 46kPa static pressure at the inlet, or 46kPa + atmospheric pressure? or Does is the MAP induced by the piston sucking and pushing the air, so I would just need to specify atmospheric pressure? or Any other suggestions? I would greatly appreciate any help Best regards, abm |
