ABSTRACT:
Routines are run which briefly monitor a selected parameter and ascertain, based on the magnitude of the parameter, the use of heavy, regular or light fuel. These routines set correction factor values which are used to modify fuel injection, ignition timing and the like, during transient modes of engine operation. Tables used in the identification are recorded in two-dimensional form. Following an identification and correction factor determination, the programs are adapted to terminate very early in the run. Depending on the change in fuel tank volume, previously obtained data is assumed to still hold true and analytical routines forshortened to obviate redundant re-analysis and lighten processor load.
