Performance, Emission, Vibration Investigation of Waste Chicken Fat Methyl Ester as Fuel and Diethyl Ether as Additive in IC Engine

Biodiesel is becoming more popular because it is good for the earth and cheaper than diesel made from oil (B00). Acid esterification and base transesterification can be used to make biodiesel, which is a type of fuel made from chicken fat that would otherwise be thrown away. The chosen feedstock, chicken fat, was found to be inedible, to have a higher fatty acid value, to be easily available in our region at a lower cost and in large quantities and, most importantly, to be a waste product (i.e., CFO) that we are trying to turn into a value-added product called Chicken Fat Methyl Ester (CFME). The known standards of ASTM-6751-9b were used to describe the properties of the manufactured fuel, such as its density, viscosity, calorific value, flash point and fire point, among other things. Diethyl ether, which is also sometimes called DEE, was found to be a good solvent and an ingredient. The DEE also said that it would cut down on the amount of blend that was used, so it was added to the mixture of CFME and B00. The parts CB9DEE5, CB18DEE5, CB27DEE5, CB36DEE5 and CB45DEE5 were blended so that the mixes would be uniform. The B00 fuel is considered to be the normal fuel. All of the mixed fuels, including B00, were tried in a single-cylinder diesel engine under different loads, such as 3, 6, 9 and 12 kg. The experiment records were looked over and the results are shown below. This is where we talked about performance measures like BSFC and BTE, as well as pollution factors like HC, CO and NOx, among others. Compared to B00, the CB27DEE5 blend has a higher brake heat efficiency of 29.12% for a Compression Ratio (CR) of 17, while B00 only got to 28.29%. Also, the CB27DEE5 blend has led to a 36.95%, 13.48% and 16.07% drop in CO, HC and NOx emissions, respectively, for a CR of 17. The vibration study, on the other hand, showed that for CR 17, when the situation was set to full load, the amount of vibration went up by 182.3%. It was found that CB27DEE is the main blend that can replace B00% gasoline without making any changes to the engine.
