Abstract
Historically transient combustion performance is described by attribute data, the number of misfires or slow burns or graphical with plots of IMEP. These measures help developers improve transient combustion performance but do not work well for experimental analysis methods. All design of experiments, analysis of variance, optimization methods and modeling, require variable data.
A method of transient IMEP analysis has been developed to quantify tip in / out combustion and total engine combustion stability during engine start and warm up. The Cycle Standard Deviation IMEP shows sensitivity and stability making it an excellent tool for analytical analysis methods for engine calibration development.
