Environmental Effects of Biodiesel Engines Fuelled by Waste Cooking Oil and Metal Nano Additives

Abstract

The experiment yielded significant findings. Transesterification was used to turn waste cooking oil into biodiesel, a renewable energy source. The fuel mixture ratios were adjusted to measure engine performance and lower fossil fuel emissions. The study examined power generation, torque, consumption per hour, and emissions of unburnt hydrocarbons and carbon dioxide. The diesel engine's power output was 5.2 kilowatts. Biodiesel, derived from discarded leftover cooking oil, was synthesized by blending it with diesel fuel at a concentration of 20%. Engine performance tests revealed no statistically significant variations in power or torque across the various commercial diesel mixes. Notably, the consumption of diesel petroleum for commercial purposes increased by 15% and 20% per hour, respectively. The main advantage was the reduction in carbon dioxide emissions, which was 20% for all combinations of commercial fuel and biodiesel, compared to only commercial diesel.
