Optimization of electronic fuel Injection system for improved Performance and emission in biodiesel Operated diesel engine

Abstract

Diesel engines are more efficient for heavy duty vehicles Intensive newlinemultiple research have been carried out on the suitability of diesel engine to newlinelight duty vehicles and stationary engines The most important problem faced newlinein diesel engine development is control of oxides of nitrogen and smoke newlineemission Pilot injection reduces diesel knock ignition delay and controls newlinerapid pressure rise Thus pilot injection controls Oxides of nitrogen emission newlineto a greater extent As per Bharath stage VI regulations stipulates that the newlineemission of NOx must be reduced to half of Barath stage IV Newer newlinecombustion techniques introduced to reduce NOx and Particulate matter newlineusually have high EGR rate and advanced main injection leading to higher newlineCO emission and poor SFC newlineIn this research work effects of split injection methods and dwell newlineangle between injections on diesel engine combustion and emission newlinecharacteristics were studied experimentally newline newline
