Optimisation of Joint Operation of Pressure Waves Compressors of Type Comprex with Diesel Engines

Abstract

Optimization of the joint operation of the Comprex unit with the Diesel engine can be achieved by driving the compressor with a variable speed independent of engine one. In this paper, we present some of the results obtained from experimental research of a Diesel engine supercharged with a Comprex unit driven by an electric motor. For each of the Diesel engine’s operating modes (speed and load), with Comprex being driven sequentially with 4-5 speeds, the optimum driving speed was determined for Comprex so that the Diesel engine will provide an appropriate behavior regarding environmental and energy aspects, the evaluation criteria being, in this case, the specific fuel consumption and the smoke emission.
