How do you calculate air flow in a diesel engine?
How do you calculate air flow in a diesel engine? If we want to calculate the CFM (Cubic Feet per Minute) for a 4 cycle motor we can multiply the cubic inch displacement of the engine by the maximum rpm (Revolutions Per Minute) and divide the result by 3456. Then we multiply the results by the volumetric efficiency of the motor. What air pressure is needed for air starting a diesel engine? Normally, compressed air at 20 to 30 bar pressure is required to start an engine in a certain direction. The compressed air which is inserted into the cylinder...
