Effects of Biodiesel Derived By Waste Cooking Oil on Fuel Consumption and Performance of Diesel Engine

Biodiesel is the alternate fuel which is derived from renewable sources either is vegetable oils or animal fats. For that reason, the vehicle run by Bio- diesel Fuel (BDF) has been a potential option and the alternative sources of fuel are receiving a lot attention in the automotive industry. The use waste cooking oil (WCO) biodiesel as an alternative fuel in engines has advantages from both economic and the emissions of carbon monoxide (CO) and hydrocarbons (HC) in the exhaust gas. Purpose of this study is to investigate the effects of waste cooking oil blended fuel, engine speed and test load conditions on the fuel properties, combustion characteristics and engine performance. The engine speed was varied from 1500 to 3000 rpm, load test condition varied by dynapack chassis dynamometer in 0, 50 and 100% and blends of 5(WCO5), 10(WCO10) and 15vol%(WCO15) waste cooking oil with the diesel fuel. The results showed that the use of WCO as biodiesel results in a higher fuel consumption rate, especially at low engine speed and full load condition.
