Performance and Emission Characteristics Of CI Engine Using Waste Cooking Oil As An Alternate Fuel

In presence scenario,thegreatest potential represent as biodiesel production. The major drawbacks of the petroleum diesel, producing emission pollutants from the diesel engines to the environment. To avoid such problem, concentrating on alternate fuel. It plays an important role for the non-disturbance of the atmosphere. Waste cooking oil (WCO) was used to produce biodiesel fuel in order to reduce wastes polluting the environment. This paper deals on impact of biodiesel performance and emission characteristics of CI engine. But the larger viscosity of any waste cooking oil (WCO) is found major problem in use of an engine directly. The properties of fuel such as calorific value, flash point and cetane number of the biodiesel were to be analysed. The performance and emission tests were carried out by B25, B50, B75 and B100 blends of waste cooking palm oil at different loads and such results were compared with petroleum diesel at 200 bar and 230btdc and 210bar and 230btdc. This Performance results reveal that the biodiesel gives higher brake thermal efficiency and lower brake-specific fuel consumption with the different blendingrsquos. Emission results showed that in most cases, NOx is increased, and HC, CO, and PM emissions are decreased. Through this experimental test which type of blending was found the best suitable for engine. In this paper, various blends of waste cooking palm oil and varying the injection parameters such as injection timing, crank angle to increase the performance of an engine and mutually reduces the emissions without any modification of diesel engine
