BARM: Bi-Angular Rotation Machine

  • Boris SchapiroEmail author
Conference paper


This work is an elaboration of the initial studies presented at the International Conference on Sustainable Technologies, 2011. The BARM machine, originally in the form of a compressor, will be presented here as an internal combustion machine and compared with a classic reciprocating diesel engine. A simplified thermodynamic analysis will also be presented. Power densities of BARM engines should be significantly greater than that of reciprocating engines with the same thermodynamic efficiency.
