Effects of antioxidant and ceramic coating on performance enhancement and emission reduction of a diesel engine fueled by Annona oil biodiesel

Abstract

Background: A broad investigation on alternative source of energy has been going on to find a solution to multi-faceted fossil fuel concerns namely exhaustion of fuels, energy demand, harmful emissions and environmental impact. Biodiesel is an environment-friendly and renewable alternative for diesel. In the present work, Annona seed oil has been assessed as a potential feedstock for biodiesel production. Methods: A100 was characterized by FTIR and GC-MS. Propyl Gallate (PG) was characterized by morphological study using FESEM. The elemental analysis of PG was measured using EDAX analysis. YPSZ coating was found suitable to make out the potential of A100 in diesel engine. PCCU was designed to reduce the emissions by the liquid reductant in the catalyst system. The process optimization was performed by RSM and factorial experimental design. Findings: With the YPSZ coated engine, improved characteristics of combustion and performance were noticed with A100+PG. A significant diminution on CO, HC and smoke emissions were perceived with A100+PG+CE. In addition, the work was expanded with the application PCCU for the lessening of NOx. A gradual decrement in NOx was observed with A100+PG+CE. Subsequently, A100+PG+CE with PCCU was deliberated as more prominent than other fuel samples in view of its engine characteristics.
