Patent ID: 6941907

Claim:
An auto-ignition internal combustion engine having a fuel/air mix and a compression ratio for auto-igniting the fuel/air mix, comprising: least one variable combustion volume having a first chamber with a power-transmitting member therein, and a second chamber into which the fuel/air mix is introduced, each said variable combustion volume further including means for controlling movement of gas, upon ignition, between said first chamber and said second chamber for controlling a rate of increase of gas pressure in said first chamber housing said power-transmitting member; means for varying an ignition point of a fuel/air mix by dynamically modifying a compression ratio for each combustion volume of said auto-ignition internal combustion engine, so that auto-ignition commences at a pre-determined point during an engine cycle depending upon said variable volume of said chamber such that auto-ignition occurs when the variable volume of one of said first and second chamber reaches a predetermined volume; and, means for controlling rate of increase of gas pressure for regulating force due to combustion thereby applied to said power-transmitting member associated with each said combustion volume.
