The idealized limited pressure compression ignition cycle: an empirical treatment of its response to varying operating parameters

A conventional analysis of the liffiited-pressiire cimpression-ignition cycle results in theoretical epilations that express osjrcle performance as a function of the thermodynamic properties of the working fluid at salient points in the cycle. Thus the assessment of cycle performance is based on a complete cycle computation carried out with the aid of thermoclynamic charts. This approach does not produce speedy and accurate results because a) the procedure involves lahoriotzs trial-and-error methods, and b) the charts available do not cover the whole range of mixture strengths at which an internal combustion engine following this cycle may operate.
