ABSTRACT:
An aspect of the invention provides a method for operating a workable homogeneous charge compressed ignition engine in which a compression ignition operation is performed by spark ignition to shorten a load input time and a load cutoff time. In the homogeneous charge compressed ignition engine operating method, a mixture gas is burned by compression ignition in a combustion chamber, and fuel and air are previously mixed to produce the mixture gas. The homogeneous charge compressed ignition engine includes a spark ignition device53which performs spark ignition to the mixture gas. A temperature controller35substantially keeps an intake air temperature of the mixture gas constant. A spark ignition operation, a spark-assist compression ignition operation in which spark ignition is supplementarily used, and a non-spark compression ignition operation in which the spark ignition is not used are switched according to magnitude of a load.
