ANALYSIS OF ELECTRONIC FUEL DIRECT INJECTION SYSTEM IN SPARK-IGNITION ENGINES
|
| |
|
Summary :
|
|
SUMMARY. SINCE THE INVENTION OF THE SPARK-IGNITION ENGINE, OR OTTO CYCLE ENGINE, EXTENSIVE STUDIES HAVE BEEN ACCOMPLISHED IN ORDER TO REACH HIGH PERFORMANCE, LOW EMISSION AND GOOD FUEL ECONOMY, SIMULTANEOUSLY. RECENTLY, AUTOMOTIVE INDUSTRIES HAVE RESTARTED THE PRODUCTION OF ELECTRONICALLY CONTROLLED ENGINES WITH FUEL DIRECT INJECTION SYSTEMS. THE TECHNOLOGY OF DIRECT INJECTION PRESENTS CHARACTERISTICS THAT CONTRIBUTE IN A POSITIVE WAY TO REACH THE OBJECTIVES ABOVE MENTIONED. THIS PAPER PRESENTS THE STATE-OF-THE-ART OF DIRECT FUEL INJECTION IN SI ENGINES, THE CURRENT TECHNOLOGY TO MAKE POSSIBLE ITS ACCOMPLISHMENT, THE CHARACTERISTICS OF THE ENGINES USING THIS SYSTEM AND A COMPARATIVE EXPERIMENTAL STUDY BETWEEN THIS SYSTEM AND THE INDIRECT FUEL INJECTION ONE.
KEY-WORD: DIRECT FUEL INJECTION, MIXTURE, SPARK-IGNITION.
