Four-cycle Stirling engine for powering vehicle or machine has double piston units consisting of expansion piston fixed by piston rod to compression piston

摘要

The engine has two double piston units. They operate with their phases offset from each other. Each one consists of an expansion piston (1, 6), which is connected by a piston rod (3, 8) to a compression piston (2, 7). The pistons rods have extensions (4, 9) on the compression-piston side, mechanically connected to the transmission.
