The Performance Testing of Biodiesel Oil Produced from Waste Cooking Oil by Using a Prototype Solar Reactor for Agricultural Diesel Engines

Abstract

Biodiesel oil is one of the liquid fuels that generally employed with small agricultural diesel engines. The most widely raw material for biodiesel production is waste cooking oil. In this research work presented the biodiesel production from waste cooking oil with a prototype solar reactor and testing the obtained oil both in terms of physicochemical properties following the EN14214 and ASTM D6751standard method and performance testing of engines. The results found that the final biodiesel product can be accepted within the requirements standard of bio-auto fuels such as methyl ester content, kinematic viscosity, pour point and cloud point. Additionally, a single-cylinder diesel engine was employed to test the performance of biodiesel oil and comparison with diesel oil. The data found that exhaust gases emission namely CO₂, CO, HC, and NO₂ a trend lower than petroleum diesel oil. While the performance testing of engines displayed that both of the biodiesel oil and diesel oil was not different. Thus, waste cooking oil derived biodiesel oil has an efficiency, suitability, and possibility to apply for the real application with the small agricultural diesel engines to substitute the use of petroleum diesel oil.
