Abstract:
1. A free piston linear alternator comprising: a pair of pistons, each piston axially opposed from the other within a cylinder, wherein each piston includes a respective first element configured to interact with a respective second element located on a wall of the cylinder to generate electric current stored as energy in a battery when the pistons linearly translate within the cylinder; a combustion chamber disposed between the pistons; a return mechanism configured to return the pistons to respective first positions from respective second positions after combustion; an intake system fluidly coupled to the combustion chamber for providing intake air for eventual combustion within the combustion chamber; an exhaust system fluidly coupled to the combustion chamber and comprising a power turbine transforming exhaust gas feedstream pressure into a mechanical output; and the mechanical output powering a forced induction device configured to charge the intake air within the intake system to increase the pressure of the intake air prior to being received at the combustion chamber.
