COMPARISON OF RECIPROCATING ENGINE BOOSTING SYSTEMS

The article reviews the boost systems of reciprocating internal combustion engines (ICE). It considers different variants of existing and prospective boost systems, including displacement and centrifugal compressors, turbocompressors, combined boost systems using mechanical and electric compressors. The work shows the positive effect of boosting on the performance of a powerplant and gives the comparative analysis of boost systems on the volume, efficiency of drive and compressor part, degree of pressure increase and other indicators. The positive and negative aspects of various aggregates, as well as their influence on the performance of ICEs are revealed. Based on the study there were made the conclusions and were chosen the most effective and promising directions for further research aimed at improving the performance of vehicles by the use of boost systems.
