Influence of Gasoline Components on Engine Efficiency and Emissions

Abstract

©G.B. Machado et al., published by IFP Energies nouvelles,2014. Influence of Gasoline Components on Engine Efficiency and Emissions — For the nextfew decades, it is expected that fossil fuels and bio-fuels used in internal combustion engines willremain the primary source for vehicular propulsion. This justifies the intense worldwide researchand development effort to comply with the challenges of increasing efficiency and reducing internalcombustion engine emissions. The modeling of commercial fuels and engine combustion processespresents great challenges. There is also the need to better understand how different fuel componentsinteract and influence engine combustion and performance parameters. In the present work, surrogate fuels were used to implement methodologies to evaluate the influence of fuel components onfuel properties and multiple engine combustion and performance parameters. Special attention isgiven to engine efficiency and emissions behavior and their correlations to fuel properties and othersperformance parameters of the engine. The potentials of each component and corresponding chemicalgroup were identified for different engine designs. The results combine information and methodologiesthat can be used to develop fuels for different applications.
