Supercharging with Comprex® to Improve the Transient Behavior of Passenger Car Diesel Engines 860450

Transient conditions are typically encountered in passenger car engine operation, and they have a major impact on the control system driver/vehicle, as well as on emissions. While turbocharging generally deteriorates the transient behavior of a vehicle engine, supercharging with the pressure wave machine Comprex retains characteristics which are nearly equal to those of a naturally aspirated engine. The elements involved in the transient process are discussed, and their effect on road performance and emissions is shown on the basis of experimentally obtained data.
