This paper presents a novel type of combustion engine that was invented only seven years ago and has been perfected over the last few years. The Braun linear engine is eminently suited to drive reciprocating compressors, pumps, and other machinery which accept linear power input. The unconventional starting is an important asset. An engine compressor of this design weighs less than one-third of the conventional machine and has only two major moving parts. It is more durable, reliable, uses less fuel, and is completely balanced.
