Intelligence Fuzzy Logic System to Diagnosis and Control Spark Ignition Engines

Abstract

Air pollution is one of the important challenging issues these days that researchers have been trying to maintain it in a normal range. The emissions of vehicle engine exhausts are responsible for fifty percent of air pollution. There is a tendency to develop of engine control which works in a simple way. in this paper a simple fuzzy logic (FL) control has been developed which is used for defining engine system faults and control and maintain them in a normal range without use any complicated mathematical equation and any fault sensor.
