Partial sterling combustion engine design2008-08-28 18:29:38 by wuzawuzzal
The main idea is to have the cylinders charge and detonate fuel in an computer controlled automated way as to reduce the amount of combustion cycles that would other wise be necessary to keep the engine running.
The piston is directly connected to a pneumatic actuator that extends and retracts to either draw in fresh fuel or expel exhaust gases. A charge is loaded and valves are operated pneumatically to open a path to the drive train or to exhaust spent fuel. A pressure relief valve is installed to prevent over pressure and also to direct excess cylinder pressure to a pressure tank (not shown) to be used to power actuators
