Abstract
To investigate the reduction of fuel consumption in a downsizing gasoline engine equipped with a Variable Geometry Turbocharger (VGT), 1.6L VGT gasoline engine model was built with a Cooled Exhaust Gas Recirculation (EGR) system by using a 1D cycle simulation software (GT-POWER). As a result of comparing the conventional Waste-gate Turbocharger to a VGT in fuel efficiency of driving cycles (JC08 and WLTC), the potential to reduce the fuel consumption by the combination of VGT and Cooled EGR was found due to the decrease of pumping loss using a VGT.
