Abstract:
A combustion engine comprising:a combustion chamber means for receiving fuel and oxidant to support combustion, an integrated fuel metering and ignition means, and means for converting heat produced by said combustion into work, wherein said integrated fuel metering and ignition means is comprised of a fuel control means that is operable to receive pressurized fuel from a fuel storage and delivery means and to convey said pressurized fuel into said combustion chamber means and includes means for controlling intermittent flow of said fuel into said combustion chamber means at times in which the pressure in said combustion chamber means is less than said pressurized fuel to form a stratified charge mixture of said fuel within surplus oxidant in said combustion chamber means and includes a pressure normalization means for minimizing the pressure difference between said combustion chamber means and said means for controlling intermittent flow of said fuels, and in which said stratified charge mixture is ignited by an ignition means at a time that is provided by a controller means to provide conversion of the heat released by said combustion chamber means into work by said means for converting heat into work before said heat is transferred to defining surfaces of said combustion chamber means.
