Engine performance and emission studies by application of antioxidant as additive in biodiesel diesel blends

Abstract

This study assesses antioxidant results as a biodiesel additive as fuels in the diesel engine. Biodiesel usage into diesel engine decreases the dependence on imported petroleum and yields benefits like reduction in global warming and engine exhaust emissions. However, inherent drawbacks like lower CV, higher viscosity, and density while increased SFC and NOx emissions limit the biodiesel application in engines. In this way, the additives in the form of antioxidant play a prominent role to mitigate the drawbacks of biodiesel. This investigation main cause to decrease NOx emissions by useof DPPD additive with biodiesel blends. This study uses three different Diesel, B20, B20DPPD1000 test fuels to be prepared at a different volume mixing ratio. This results reported that increase BTE and reduce BSEC of B20 fuel with DPPD additive as contrasted to other test fuels. Also the vital decrease of NOx and CO emissions but slightly increase HC emissions obtained use of B20 fuel with additive.
