Emissions and Performance of Diesel Engines Correlated with Biodiesel Properties

Abstract

It has been demonstrated that B20 biodiesel can be used in diesel engines without modifying their specifications. It is still being developed to reduce dependence on diesel fuel by developing biodiesel with a higher percentage of palm oil. Alcohol is added to biodiesel to reduce problems with fuel injection due to its high viscosity. In this study, the biodiesel properties of diesel-palm cooking oil-methanol/ethanol/butanol blends are investigated in relation to diesel engine performance and potential exhaust emissions. The percentages of palm cooking oil used were 30%, 40%, 50%, 60%, 70%, 80%, and 85%. A 15% concentration of methanol, ethanol, and butanol alcohol was used. According to chemical and physical tests, biodiesel with a higher palm oil content had poorer properties. A biodiesel blend that combines diesel, palm oil, and methanol can perform almost as well as diesel fuel in terms of exhaust emissions and engine performance.
