Effect of Cetane Number on Specific Fuel Consumption and Particulate Matter and Unburned Hydrocarbon Emissions from Diesel Engines

<table>Pressure profiles in the combustion chamber for the base fuels with the lowest CN (S300_45 and S450_44) showed a higher ignition delay time than their respective S300_50 and S400_50 formulations.</table>
