The cascade exchange pressure supercharger of transport diesel with deep cooling cycle air

Abstract

The new principle of the organisation of working process of the combined supercharging system of transport diesel with the Cascade Pressure Exchanger (CPE) has been described. It allows considerably to raise level of forcing of the engine by supercharging at the expense of expansion of effective air supply area and coolings of supercharging air to temperature below an ambient. Substantive postulates of imitating model of work of combined engine(CICE) have been stated. Some results of calculation-experimental investigations of supercharging system of the engine 6ЧН12/14 have been given. It confirms the possibility of the essential improvement tractive and fuel-economic factors of the transport installations in broad range of the working conditions.
