Effects of exhaust gas recirculation on diesel engine using hybrid biodiesel

Abstract

The primary aim of this study is to alternate between conventional fossil fuels and reduce the emissions of greenhouse gases and sulphur dioxide from the diesel engine. In the current study, in order to mitigate NOx emissions, the EGR technique was implemented utilizing hybrid alternate biodiesel at three varying proportions of 5%, 10% and 15% at an optimum compression ratio of 20:1. The findings demonstrate that for a hybrid alternative biodiesel at a compression ratio of 20:1 and fully loaded, the BTHE is 31.8% with 10% EGR. With 15% EGR, the peak pressure for the hybrid biodiesel is lower than it would be without EGR by around 2.28%. When EGR is increased, the ignition delay and NOx emissions are reduced slightly. With only an increase in EGR rates of up to 10%, BSFC values were reduced efficiently. The hybrid biodiesel with 10% EGR achieves a reduction in exhaust gas temperature to 341 ?C.
