H2O2 as fuel additive in bio-diesel for emission reduction and performance enhancement of variable compression ratio (VCR) diesel engine

Abstract The world cannot imagine without an automobile. But the emissions of the vehicles are at an undesirable level. The present work investigates the effect of engine performance and emissions in a single-cylinder four-stroke variable compression ratio (VCR), diesel engine using hydrogen peroxide (H2O2), diesel, and CIME (Calophyllum Inophyllum methyl esters) blends. Biodiesel has a higher viscosity, lower calorific value than mineral diesel, and it is used as a blend in diesel up to a certain percentage because of its drawbacks. But biodiesel usage in IC engines significantly reduces emissions and exhaust gas temperature. In the present work, an attempt has been made to use biodiesel blend with hydrogen peroxide(H2O2) in the engine. Biodiesel was blended with Hydrogen, and oxygen-rich additive H2O2 at 5, 10, 15 percentages and was tested and compared with biodiesel (B100) and diesel. The test results show that the engine fueled with biodiesel and H2O2 blend improves engine performance and decreases the NO and CO Emissions compared with biodiesel (B100). The 10% H2O2 blend has performed near to diesel.
