Global oil reserves are facing great stress because of massive fuel consumption worldwide and the booming world population. These fossil fuels, when processed, affect the environment by releasing greenhouse gases. The outstanding usage of oil inspired many countries to develop alternative fuels. Biodiesel is the future prospect to fulfil the energy needs. It is compatible, ready to use fuel and can easily be deployed in the existing engines by combining it with conventional fuel (diesel). Biodiesel emits a lower amount of greenhouse gases. In this experiment, we first synthesized biodiesel using methanol, NaOH and vegetable oil through transestrification process. After that, we prepared a sample for 14% biodiesel which was then used to run a 4-stroke compression ignition (CI) engine that was attached to the engine testbed. After that, we re-run the same 4-stroke CI Engine with pure-diesel. From the data obtained and subsequent data-analysis, the 14% biodiesel came out to be less efficient (avg. 3% lower brake power and 8.9% lower brake thermal efficiency) and more expensive (avg. 12.8% higher fuel consumption) as compared to pure-diesel.
