The purpose of this paper is to demonstrate the superiority of COMPREX® as a supercharging device. Comprex,® a gas-dynamic pressure-wave machine for supercharging vehicle diesel engines in the 100-500 BHP range, uses exhaust gas energy for compressing intake air. Based on a different physical mechanism, it avoids several of the turbocharger's disadvantages. Comprex supercharging gives high torque down to less than 40% of rated speed. Almost instantaneous response combines with significant reductions in acceleration smoke. An increase in maximum compression ratio and efficiency and a wider speed range were achieved by recent development work.Endurance tests have been successfully performed, and the system has been redesigned for smaller dimensions and adapted to production requirements.
