The power output (P) of an Compression-Ignition (CI) engine in aircraft design represents the mechanical power produced by the engine. This power is used for propulsion, driving the aircraft’s propeller or jet propulsion system. The formula, definition, and SI unit for Internal Combustion Engine Power Output are as follows:
Compression-Ignition (CI) Engine Power Output (P) : This represents the mechanical power produced by the internal combustion engine and is typically measured in watts (W), kilowatts (kW), or horsepower (hp).The formula for calculating Compression-Ignition (CI) Engine Power Output depends on the type of engine.
- Mean Effective Pressure (MEP): This represents the average pressure in the engine cylinder during the power stroke and is typically measured in pascals (Pa) or bar.
- Engine Displacement (V): This is the total volume of all engine cylinders and is typically measured in liters (L) or cubic centimeters (cc).
- Engine Speed (N): This is the rotational speed of the engine’s crankshaft, typically measured in revolutions per minute (rpm).
