Abstract
A method for designing internal combustion engines can include selecting a compression ratio that produces a compression temperature just below the autoignition temperature of a fuel/air mixture, selecting a fuel equivalence ratio that produces a combustion temperature below the threshold temperature at which NOx formation or autoignition of the mixture occurs, and selecting an expansion ratio greater than the compression ratio.
