For the next few decades, it is expected that fossil fuels and bio-fuels used in internal combustion engines will remain the primary source for vehicular propulsion. This justifies the intense worldwide research and development effort to comply with the challenges of increasing efficiency and reducing internal combustion engine emissions. The modeling of commercial fuels and engine combustion processes presents great challenges. There is also the need to better understand how different fuel components interact 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 on fuel properties and multiple engine combustion and performance parameters. Special attention is given to engine efficiency and emissions behavior and their correlations to fuel properties and others performance parameters of the engine. The potentials of each component and corresponding chemical group were identified for different engine designs. The results combine information and methodologies that can be used to develop fuels for different applications.
