EGR improved both Brake Specific Fuel Consumption (BSFC) and Brake Thermal Efficiency (BTE) for the studied fuels with respect to baseline conditions. Their paper is published in the journal Fuel. On the other hand, GDI engines have reported to increase the concentration of the Particulate Matter (PM) emissions.
