摘要

This project work is significant globally as the world is raising concern on global environmental challenges seen in recent times. Just of recent, the president of Nigeria Dr. Goodluck Jonathan was at UN Convention held at Geneva to join in world to deliberate on sustainable Energy and global warming issues. One critical source of environmental pollution is found to be associated with S.I. Engines running on Leaded Petrol. This Leaded Petrol contains Lead Compound known as Tetra Ethyl Lead (TEL) which gives out a poisonous substance. TEL is known with its ability to resist knock and raise octane rating. This paper examines the effect of replacing poisonous lead use as anti-knock agent with alcohol. The sources of alcohol in Nigeria are numerous and includes Woodchips which is non-edible Lignocelluosic Biomass. Alcohol obtained from these sources was blended with Petrol at different Blend ratio of 5% 10%, 15%, 20%, 30% and 40%. The purpose of blending is to obtain an optimum anti-knock blend ratio resulting to satisfactory engine operations. Alcohol is a renewable energy which is environmentally friendly. The test run of the blends was made on S.I Engine. The Engine Performance was evaluated at full-load condition. The results show that at full load, 20/80 ethanol/petrol blend gave the optimum engine performance.
