الوصف: | The influence of turbulence, through changes in swirl velocity and exhaust gas recirculation (EGR), and the combustion process was investigated theoretically and experimentally in a homogeneous charge compression ignition (HCCI) engine fuelled with diesel fuel compatible with EN590. The results show that combustion chamber geometry can play a relevant role in HCCI combustion. The combustion process in a high swirl bowl in piston combustion chamber has been compared to that in an almost flat piston (nearly disk shape). Under the same operating conditions—engine speed, injected fuel per cycle, and EGR rate—the peak of the heat release rate for the high swirl piston was lower compared to the disk-shaped combustion chamber. In addition, combustion duration was increased, which is thought to be due to the reduction of gas temperature, larger heat losses, and mixing improvement. Intensity swirl control offers a potentially effective approach to modulating the combustion process in HCCI engines—although a penalt... |
