Patent ID: 7637239

Claim:
A method for enhancement of the conversion of pressure and heat associated with the combustion process of a air/fuel mixture disposed within a combustion chamber of an ICE having an intake valve and an exhaust valve housed therewithin comprising the steps of; introducing a quantity of air/fuel mixture into the combustion chamber, transferring a portion of said quantity of air/fuel mixture into a pre-ignition chamber disposed externally of the combustion chamber and in fluid communication with the combustion chamber through at least a central channel and a lateral channel, igniting said air/fuel mixture within the pre-ignition chamber to thereby generate a flame front which propagates from said pre-ignition chamber into said central channel, prior to the exit of said flame front from said central channel into said combustion chamber, diverting a portion of said flame front into said lateral channel, directing said diverted portion of said flame front into said combustion chamber via a first exit port from said lateral channel in a direction aligned with the location of the intake valve at a first velocity, and directing a second individual flame front exiting said central channel via a second exit port in a direction aligned with the location of the exhaust value at a second velocity which is greater than said first velocity, whereby said first and second flame fronts effect ignition of air/fuel mixture in the respective vicinities of the intake and exhaust valves, said second flame front being delivered to and commencing ignition of air/fuel mixture in the vicinity of the exhaust valve at a time prior to the buildup of pressure and heat within the combustion chamber in proximity to the exhaust valve due to the ignition effected by said first flame front in the vicinity of the intake valve building up pressure and heat sufficient to effect detonation of air/fuel mixture in the vicinity of the exhaust valve, said pre-combustion of said portion of said air/fuel mixture within said pre-ignition chamber being effected at a time within the cycle of the ICE wherein the rotational position of the crankshaft, hence the piston associated with the combustion chamber, achieves a position not in excess of about five degrees prior to top dead center, thereby maximizing the buildup of pressure and heat within the combustion chamber, without detonation, at a time which is most advantageous for conversion of such pressure and heat to energy for driving the piston into and through its power stroke.
