... stroke * Torque generation and acceleration Additional components can be added to the model to gain greater accuracy in the simulation. Throttle The simulation on the throttle body is based on the control input of the angle of the throttle plate. The rate in which the model induces air into the intake manifold can be expressed as the outcome of two functions. One is the function of the throttle plate angle and the other is an atmospheric function of the manifold pressure. In the case of greater vacuum, the flow rate through the throttle plate is sonic, therefore, it is only a function of the throttle angle. Intake manifold Intake manifold has a different equation to the manifold pressure. The difference of the incoming and outgoing mass flow rate provide a net rate change of mass with respect to time. This according to the ideal gas laws is proportionate to the time derivative of ...
