Abstract

To improve air efficiency in the combustion chamber, a new separated swirl combustion system (SSCS) was developed and is proposed herein. The SSCS performance was validated against a double swirl combustion system (DSCS) in an experimental test with a single-cylinder diesel engine. The experiment results show that the SSCS effectively reduces fuel consumption and soot emission, with a maximum decrease in fuel consumption of 5.41% (when the effective power was 17 kW) and a maximum decrease in soot emission of 20.48% (when the effective power was 43 kW). Then, simulation was used to investigate and reveal the mechanisms behind the fuel/air mixture in the chamber. The simulation results show that the angular fuel sprays collide with the unique circular ridges in the SSCS, which improves air utilization in the chamber and accelerates the fuel/air mixture, reducing soot emission.
