Abstract
An experimental investigation is conducted to evaluate the use of a diesel fuel supplement, specifically a 25/75% and a 50/50% blend of waste olive oil and commercial diesel fuel, in an experimental swirl chamber, four stroke diesel engine. The influence of the blends (diesel fuel + olive oil), for a range of loads on specific fuel consumption, maximum pressures, exhaust smokiness and exhaust gas emissions (nitrogen oxides, hydrocarbons and carbon monoxide) is investigated. As a baseline running with the diesel fuel only was used. The study shows a small penalty in specific fuel consumption when using the blends and a slight deviation, from the "baseline" values, for the exhaust emission levels. Theoretical aspects of diesel combustion are used to aid the interpretation of the observed engine behavior.
