Simulation and Experimental Research on Combustion Characteristic of Double Swirl Combustion Chamber

The double swirl combustion chamber and shallow basin shaped combustion chamber were analyzed by 3-D simulation under different working conditions and their comparison experiment was carried out.The results show that the double swirl chamber has the advantages of combustion rate and efficiency over the shallow basin shaped combustion chamber,which proves that the double swirl combustion chamber is more suitable for the fast combustion of high power diesel engine.The inner chamber of double swirl system can apparently improve the air utilization and accelerate the mixing process.
