Study of Resonant Systems in Order to Optimize the Parameters of the Engine Intake Manifold of Formula SAE Race Car

The authors propose the variant of model of the intake system a particular type, taking into account the specificity of high-speed internal combustion engine. The basis of this model is the principle of converting the acoustic impedance. The algorithm of this model is formed on the basis of joint consideration of the equations of conservation the impulse, mass balance and condition. The model is characterized by flexibility and can be used to analyze of the charge state in any local area of the intake system a complex configuration or the whole system. The proposed procedure for modeling of unsteady gas flow at the intake causes the possibility of finding a limit increasing the torque of internal combustion engine at a predetermined section of its speed.
