Opposed free piston linear alternator

摘要

A free piston linear alternator includes a cylinder having a pair of bounce chambers, a pair of scavenging chambers, a pair of opposed pistons and a combustion chamber disposed between the opposed pistons. The pistons are axially opposed from each other and generate electric current when each of the pistons linearly translate. Each of the bounce chambers is disposed between respective ones of the pistons and a respective outer end of the cylinder and includes substantially constrained air configured to return respective ones of the pistons to a respective first position from a respective second position after combustion.
