Alternative Solutions for Supercharging with Aggregates of Turbocharger Type

Abstract

In order to determine to what extent the supercharge with a pressure waves compressor of type Comprex represents an alternative to the supercharge with a turbocharger, this paper presents comparatively the values of ecological and economical parameters obtained from experimental research of a Diesel engine supercharged consecutively with turbocharger and with an aggregate of type Comprex driven with a constant speed by an electric motor. Supercharging using a Comprex unit driven with a constant speed brings environmental and economical performances for the engine thus supercharged, a fast response in acceleration, and a functional simplicity of the supercharged system.
