A method of transitioning between homogeneous charge compression ignition and spark ignition in a combustion chamber of an engine that is configured for homogeneous charge compression ignition under at least some engine operating conditions and for spark ignition under at least some engine operating conditions, the method comprising heating contents of the combustion chamber with a glow plug prior to transitioning between homogeneous charge compression ignition and spark ignition.

System and method for facilitating homogeneous charge compression ignition

A method of maintaining homogeneous charge compression ignition when a temperature within a combustion chamber decreases below an autoignition temperature in an engine that is configured for homogeneous charge compression ignition under at least some engine operating conditions and for spark ignition under at least some engine operating conditions, the method comprising selectively heating contents of the combustion chamber with a glow plug.
