Abstract
Diesel engines are utilized in the transportation sector owing to their high efficiency. In recent years, biodiesel and higher alcohols have taken the attention of researchers as promising alternative fuels for diesel engines. In this article, diesel fuel is mixed with corn oil biodiesel at the ratio of 80:20 (v/v). 2%, 5% and 8% of 1-pentanol (v/v) are mixed into the diesel fuel-corn oil biodiesel binary blend for obtaining ternary blends. The impacts of ternary blends on some performance and combustion behaviors of a diesel engine are researched. Power and exponential models to predict exhaust gas temperature linking to maximum pressure rise rate, brake effective power, lower heating value, engine speed, equivalence ratio and latent heat of evaporation are derived through the least square error method. The use of ternary blends results in lower brake effective power (5.4246%-6.0066%), exhaust gas temperature (5.9504%-7.9459%,) and peak cylinder pressure (6.8502%-7.1629%), compared to diesel fuel. The average relative errors are specified as 1.9214% and 2.9749% for the power and exponential models, respectively.
