A positive displacement engine with integrated positive displacement rotary fluid compressor has a piston chamber, a piston disposed in the piston chamber, a rotary compressor housing, the rotary compressor housing have first and second interconnected rotary compressor chambers, and first and second rotary compressor elements disposed in the first and second rotary compressor chambers, respectively. The first and second rotary compressor elements each have an elongated arm portion pivotally connected to the piston, and have a generally circular base portion eccentrically pivotally connected to first and second crankshafs. The first and second crankshafts are interconnected to rotate synchronously in opposite directions such that the rotary compressor elements rotate, eccentrically about the crankshafts, within the rotary compressor chambers, synchronously in opposite directions. An exhaust valve is disposed in a side wall of the rotary compressor housing and is located between the first and second compressor elements to release fluid compressed between the first and second compressor elements from the compressor housing. Linear oscillation of the piston produces synchronous, balanced opposite rotation of the compressor elements within the compressor housing, which compressor elements compress fluid therebetween that is directed out of the exhaust valve. The compressed fluid can be directed to the performance of work and/or scavenging and supercharging the piston chamber prior to the performance of work.
