Abstract:
1. A rotary engine having a housing including walls that define a cylinder, said rotary engine comprising: an air chamber for receiving and storing pressured air for use in a combustion process; a combustion chamber connected to said air chamber to receive pressurized air therefrom, said combustion chamber including a first opening for receiving fuel and a second opening for accepting an end of a spark plug to ignite fuel within the combustion chamber and an output to direct expanding gases into the cylinder; a piston operating within said cylinder and driven by expanding gases directed from the combustion chamber, said piston including a seal for preventing expanding gases from passing between the piston and the walls of the housing that define the cylinder; a valve door that provides a base against which expanding gases react to propel the piston in a forward direction, said valve door including a valve rail ensuring proper alignment of the valve door as it is lifted to allow the piston to pass to complete a rotation; a rotor coupled to said piston; and a crankshaft coupled to said rotor.
