Depleting oil reserves, rising oil costs, a lack of fossil fuel oil supply, and the issues of pollution have motivated worldwide researchers for alternative fuels for diesel engines. Vegetable edible and non-edible oil-based fuels have been shown to be a viable greener energy alternative to diesel fuels. Vegetable oils are non conventional and renewable fuels. These fuels have qualities that are equivalent to petro-diesel. These are biodegradable fuels, and produce fewer emissions while burning. It has been discovered that all of the gasoline blends, KB15 produce the least CO. When compared to other fuel mixes like KB5, KB10, KB20, and KB100, KB15 produces 8 to 9 percent less CO and CO2. For all load conditions, KB100 has a higher BSFC than diesel. KB15 had a lower BSFC than diesel, indicating that it was the best mix in terms of fuel efficiency. At full load, KB100 has a higher amount of unburned hydrocarbon as compared to diesel due to more fuel is injected, resulting in a richer mixture and incomplete combustion. However, KB15 produces 5% less unburned hydrocarbon than diesel under all loading conditions. Because the quantity of mixed fuel grew as the concentration of biodiesel increased, the amount of NOx emitted increased, resulting in a higher temperature during fuel combustion. KB100 increases NOx emissions by up to 25% under all load conditions.
