Dimensionless study on outlet torque characteristics of an air powered engine

  • Aiming at the process of an air powered engine, the energy equation, gas state equation, continuity equation and momentum equation were used to set up non-linear differential equations of an air powered engine(APE). By selecting the appropriate reference values, the basic mathematical model was transformed to a dimensional expression. Using MATLAB/Simulink for simulation, the dimensionless outlet torque characteristics of APE were obtained. Through analysis, it can be seen that the dimensionless outlet torque of APE was mainly determined by the dimensionless crankshaft speed, the inlet effective area scaling coefficient, the outlet effective area scaling coefficient and the duration angle. The dimensionless outlet torque could be regulated by charging the inlet effective area, the outlet effective area and the duration angle to fit the change of crankshaft speed.
