Empirical experiments have been undertaken to investigate the effects of Intake Pulsating Flow on volumetric efficiency in a diesel engine which significantly affects to intake manifold of induction system. It is well known facts that the intake and exhaust gas exchange processes close relate to a diesel engine performance. In this paper the effects of change in length of the pipes and engine speed on volumetric efficiency was examined and evaluated to obtain a preliminary data which have a analytical solution basis on a non-linear one-dimensional unsteady flow by the method of characteristics. It was found that volumetric efficiency was affected by intake pulsating flow with engine speed and the pipe length. The results obtained were considered by adopting a theory of wave action.
