An Experimental and Numerical Study from Pulsating Flow in Intake Manifold 2000-01-3162

The pulsating flow in the intake system of an internal combustion engine has been studied experimentally and numerically, with the objective to improve the system performance. The experiments were carried out in a flow bench, and the intake system studied was composed of a straight pipe connected to a 1000cc engine with a single operating cylinder. The numerical simulations used the method of characteristics. Mass flow and pressure fluctuations obtained from the numerical simulations compared well with the experimental results. A fluid dynamic aperture of the intake valve was verified to differ from the geometrical aperture.
