Experimental Study of Ignition of a Gasoline-Air Mixture in a Constant-Volume Combustion Chamber

摘要

The characteristics of flame-kernel development in a premixed gasline-air mixture in a cylindrical constant-volume combustion chalmber are measured.The experiments are performed with an initial temprature of 393 K,pressure of 6 bar,and equivalence ratio PHI=0.8 with the use of various ignition systems and spark p0lugs.The schlieren pictures of the process are presented,and the measured results for flame velocity,heat-release rate,and mass fraction of the burnt fuel are analyzed.
