Comprex ^R Supercharging for Passenger Diesel Car Engines

Based on the experience with supercharging of engines in commercial vehicles, investigations have been carried out during the past two years on diesel engines for automobiles. The results as regards performance, fuel consumption, and the characteristics of the exhaust gas are very encouraging, so that a complete range of pressure-wave superchargers (PWS) is in preparation to cover a range of between about 30 and 100 kW. A high degree of charging at medium and low speeds, combined with spontaneous availability of the torque, allows the engine to be made smaller, thereby shifting the average working point towards the optimal consumption of the engine, but without sacrificing driveability.
