Distance-added vehicle widely acclaimed because it uses electric power as driving force，and also charge the battery by generator powered by engine. It not only conquers the highly-polluting of the internal-combustion engine, but also utilizes clean energy as driving force, and the most important point is keep the engine at a sustainable best situation which made the vehicle warmly popularized when it emerged. As the fact that the gasoline engine and diesel engine technology has almost reached their ceiling, distance-added vehicle and homogeneous charge compression ignition (HCCI) with its low nitrogen oxide combustion technology, low particulate emissions and the high thermal efficiency raises widespread concerns around the world. However the control of ignition and combustion reaction rate and extending the rage of operating conditions to achieve HCCI is always the crucial point and difficulty as well. Nowadays, some famous universities such as Shanghai Jiao Tong University, Tsinghua University, Tianjin University, and Huazhong University of Science are actively engaged in the study of HCCI Combustion Technology. While it is still difficult to e
