Improving the FIE Mapping of a 4-Cylinder 4-Stroke Engine for Operation on the European Drive Cycle

Improvements have been made in the electronic fuel injection map of a 1.5 liter of engine spark-ignition engine, using conventional port fuel injection (simultaneous and not synchronized.) The modifications have been made aimed at reducing the specific fuel consumption and the exhaust gas emissions, mainly in the load range of the engine that is most frequent in the stabilized European drive cycle, primarily urban driving.
