The tightening of global emissions standards and mandated minimum fuel economy requirements for automobile manufacturers have become the primary impetus behind internal combustion engine (ICE) research and development. Various low temperature combustion concepts, including homogeneous charge compression ignition (HCCI) and its variants, are being researched as viable future options for efficient internal combustion engines. This paper briefly introduces some common low temperature combustion variants, outlines the various subsystems required to control most low temperature combustion engines, and discusses the hardware and software needed to interface with these subsystems.
