An experimental study is conducted to evaluate the use of fumigated diesel fuel as a supplementary fuel for a Ricardo E-6, high speed, naturally aspirated, four-stroke diesel engine, having a turbulent combustion chamber. The supplementary diesel fuel is introduced together with the aspirated air (fumigation) at various proportions with respect to the main diesel fuel, which is injected the usual way. The influence of fuel/feed ratios (supplementary/main), in a vast range of loads, on fuel consumption, pressure diagrams, exhaust smokiness and exhaust gas emissions (nitrogen oxides, hydrocarbons and carbon monoxide) is investigated. As baseline, operation of the engine running with the main diesel fuel only (injected in the usual way) is considered. The study shows the promise of the present method and reveals that above ∼60% of a maximum load there is a big smoke reduction with only a slight penalty in specific fuel consumption. The knocking limits are also determined. The examination of gaseous pollutant levels shows an involved relation with respect to load and fuel proportions. © 1989. (EN)
