Abstract
A pressure spike modulator for engagement to the cylinders of an internal combustion engine. The device provides for adjustment of engine cylinder pressures using a reciprocating piston which provides a temporary increase in engine combustion chamber volume. Pressure from combustion chamber gases is communicated by the device back into the combustion chamber during the downstroke of the engine piston. Engine compression and peak combustion pressure may be modulated by adjusting pressure supplied to the device to resist incoming engine gases. Fuels for the attached engine may thereby be varied or substituted by adjusting the engine peak pressure and compression to one adequate for the chosen fuel.
