This paper deals with an improved design of a pressure wave supercharger for small recreational vehicles like motorbikes or snowmobiles. A pressure wave supercharger (PWS), commonly known as Comprex (or Hyprex), provides very good torque response behavior and is used to lower emissions. However, compared to a standard turbocharger system, a standard PWS system has some inherent disadvantages too. Main problems are noise emissions and the expensive manufacture. Therefore, the goal of this study is to eliminate these shortcomings and to propose a completely new design which promises easy and relatively inexpensive production. In this paper, the conceptual development of a new PWS type is presented. Methods used were computational fluid dynamics simulations and the analysis of an existing Comprex design. High attention has been paid to the producibility of the aggregate. Though there are big design differences compared to a standard PWS, the working principle per se remains the same. Due to this fact, the torque response of the whole engine system will be similar to a system with a standard PWS, whilst noise emissions, fuel consumption and CO2-emissions can be reduced further.
