Abstract


Vehicles operate in a variety of regimes, including steady-speed operating modes and transient operating modes. The operation of the internal combustion engine at various regimes involves a change in load. The throttle regulates the mass of air entering the engine by closing the intake manifold. In relation to the fact that the vast majority of operating modes are transient, the paper develops the modeling and simulations of the throttle system.
