The paper presents a theory and its experimental validation on optimum conditions of fuel injection systems and swirl flow, which gives the maximum thermal efficiency and minimum smoke emission. The theory predicts air entrainment change into fuel sprays for a variety of swirl speeds, number of nozzle holes, nozzle diameters, engine speeds, injection speeds and fuel densities. Experiments were conducted to verify the theoretical prediction. The results showed good agreement with the theory : maximum combustion rate arranged on theoretically predicted lines for number of nozzle holes and swirl speeds. The study provides opportunity for engine designers and researchers for understanding diesel combustion characteristics for injection systems and swirl flows.
