This paper introduces an improved design for pressure wave superchargers used in recreational vehicles (RV) such as motorbikes or snowmobiles equipped with smaller engines. A pressure wave supercharger (PWS), commonly known as Comprex (or Hyprex), is generally used to lower the emissions. Additionally, in comparison to a standard turbocharger (TC) system, a PWS system demonstrates superior torque response behavior. However, a major disadvantage of the Comprex are its high noise emissions and expensive manufacture. For this reason, the goal of this study was to eliminate these shortcomings and to propose a new design for a pressure wave supercharger, which is simple and relatively inexpensive to produce. In this paper, the conceptual design development of this new type of PWS is presented. The methods used were the evaluation of an existing Comprex’s design and computational fluid dynamics (CFD) simulations.
