ABSTRACT:
An apparatus and method for extracting energy from an internal combustion engine. The internal combustion engine includes a chamber having a primary piston and a secondary piston with a combustion portion of the chamber situated adjacently between the primary piston and secondary piston. The secondary piston includes a substantially lesser mass than that of the primary piston. The chamber includes at least one fluid port for supplying fuel to the combustion portion and an out-take port for releasing combustive exhaust. The chamber includes a controller for controlling the combustion therein at selected cycles of the primary piston. With this arrangement, the secondary piston is configured to draw a portion of energy from combustion controlled by the controller in the chamber. Such portion of energy is provided with a rapid response to an energy transferring portion interconnected to the secondary piston, which in turn, transfers and/or converts the energy for acting on a load or external application.
