The working process organization of a cascade pressure exchange with deep cooling charge air has been described. Tests results of a supercharge system prototype at the motorless stand has been resulted. Increasing law of cooling effect charge air at rising of a loading mode of the combined engine has been revealed. Supercharge system’s ability to provide high level of boosting has been shown. Thus charge air is cooled below ambient temperature without bringing in of additional mechanical energy on realization of refrigeration cycle.

Key words: cascade exchanger of pressure, turbo-detander, forced aspiration, deep cooling, exchange of energy, cascade compression, residual pressure, preliminary compression, compressing gas.
