PROPERTIES IMPACT OF PENTANOL ADDITIVE ON DIESEL ENGINE PERFORMANCE AND EXHAUST EMISSIONS: A REVIEW

Abstract

The adoption of alternative fuels on a worldwide scale is primarily driven by concerns about global warming and energy issues. Alcohol fuels are typically derived from many sources and are commonly manufactured locally. Pentanol, a higher carbon alcohol, can serve as a secondary component in fuel blends. It possesses exceptional characteristics such as having a higher calorific value than lower alcohol, while viscosity and cetane number (CN) are more similar to diesel than lower alcohols. The main intentions of this article are to conduct an analysis of the utilisation of pentanol as an additive with diesel and biodiesel as a fuel for diesel engines. The present study examines how the physicochemical characteristics of pentanol affect the engine performance and exhaust emissions of diesel engines. In general, the inclusion of pentanol in both diesel and biodiesel-diesel blends leads to an increase in Brake Specific Fuel Consumption (BSFC) and a decrease in Brake Thermal Efficiency (BTE) compared to diesel fuel. Ternary blends, consisting of a substantial proportion of biodiesel, have reduced emissions of carbon monoxide (CO) and hydrocarbons (HC). These emissions drop as the percentage of pentanol in the blend increases. Pentanoldiesel blends exhibit reduced NOx emissions. Pentanol as an additive to diesel and biodiesel has a substantial impact on the reduction of exhaust emissions.
