The Influence of Injection Pressure on Performance and Emission Characteristics of Waste Oil Methyl Ester Fueled Diesel Engine
Main Article Content
Abstract
The world is facing serious problem with crisis of hydrocarbon fuel and uncontrolled extraction of fossil fuels have led to the serious threat to carbon based fuels. The need to exploit bio origin based fuel to meet the world’s energy demand has been observed a long. The methyl ester has been proven liquid fuels, known as biodiesel. Such a biodiesel developed from waste cooking oil (WCO) is taken in this research along with varied injection pressure. The 220 bar injection pressure fueled by B100 shows a lowest CO2 emission than the pure diesel. The results indicated lowest NOx emission at full load. The efficiency tested with B20 and B100 WCO biodiesel recorded lower compared to diesel at 220 bar showing poor combustion of methyl ester due to higher values of viscosity and poor volatility.
