Abstract

The present disclosure provides a six-cylinder opposed free piston internal combustion engine generator. The generator comprises two free piston internal combustion engine sets, one opposed piston internal combustion engine set and two linear generator sets. Air entering cylinders is subjected to first-stage compression in low-pressure cylinder sets in the free piston internal combustion engine sets and the opposed piston internal combustion engine set and then subjected to second-stage compression in high-pressure cylinder sets, and a high pressure gas produced after the combustion is subjected to first-stage expansion in the high-pressure cylinder sets and then subjected to second-stage expansion in the low-pressure cylinder sets.
