Patent ID: 7588000

Claim:
A pressure spike modulator for sealed engagement to the combustion chamber of a piston driven internal combustion engine, comprising: a cylinder defined by a sidewall; a piston having a first wall on a first end and having a second wall on a second end, said piston having a circumference adapted to reciprocate in said cylinder; a first chamber of said cylinder defined by an area between said sidewall and said first wall; a second chamber in said cylinder defined by a second area between said sidewall and said second wall; said first chamber and said second chamber separated by a center wall communicating between said sidewall; said first wall and said second wall of said piston connected by a member communicating through said center wall; means for sealed engagement of said first chamber in a communication with a combustion chamber of a piston-driven internal combustion engine; means to pressurize said second chamber to a first pressure level; and said first pressure level determining a peak pressure achievable in said combustion chamber prior to said peak pressure causing a translation of said piston toward said second chamber and away from said first chamber.
