Control of Emissions from Marine SI and Small SI Engines, Vessels, and Equipment: Final Regulatory Impact Analysis (EPA420-R-08-014)

Multi-Dimensional Modeling of the Effects of Spilt Injection Scheme on Performance and Emissions of IDI Diesel Engines

One of the important problems in reducing of pollutant emission from DI and IDI diesel engines is trade-off  between soot and NOx. Split injection is one of the most powerful tools that makes the chance to shift the trade-off curve closer to origin.  At the present work, the effect of split injection on the combustion process and emissions of a cylinder IDI diesel engine under the specification...

Multi-Dimensional Modeling of the Effects of Split Injection Scheme on Combustion and Emissions of Direct-Injection Diesel Engines at Full Load State

One of the important problems in reducing pollutant emission from diesel engines is trade-off between soot and NOx. Split injection is one of the most powerful tools that decrease soot and NOx emissions simultaneously. At the present work, the effect of split injection on the combustion process and emissions of a direct-injection diesel engine under full-load conditions is investigated by the c...
