Homogeneous charge compression ignition engine has a potential of drastically reducing NO x and particulate matter emission, but a problem exists that accurate prediction of autoignition must be attained. The pre-ignition chemical reaction, which is affected by the characteristics of pre-mixture charge and compression process was the focus of this study to predict highly accurate chemical reactions in natural gas autoignition phenomena. The rapid compression combustion was examined using free piston type rapid compression machine, which could generate homogeneous combustion field in a reactor and reproduce n-CH 4 H 10 and natural gas autoignition phenomena. The autoignition phenomena were simulated with SENKIN code of the CHEMKIN package and grasped some important elementary reactions that are dominant at < 900 K. In n-C 4 H 10 combustion, negative temperature coefficient region at 730-760 K was confirmed. Original is an abstract.
