Advanced Control on Multi-Mode Combustion Diesel Engines during Transient Operations

燃油经济性和发动机排放是世界范围内交通运输领域的关键问题。为了有效地解决这些问题，先进的燃烧模式，如HCCI（均匀装药压缩点火）、LTC（低温燃烧）、PCCI（预混装药压缩点火），通过使发动机在接近其峰值效率的情况下运行，显示出了巨大的优势。根据美国能源部最近的年度进展报告，采用先进的燃烧模式有可能将重型发动机的燃油效率提高到55%，轻型汽车的燃油效率提高到35%至50%。

Fuel economy and engine emissions are critical issues in transportation sector worldwide. To effectively handle these issues, advanced combustion modes, such as HCCI (homogeneous charge compression ignition), LTC (low temperature combustion), PCCI (premixed charge compression ignition), have shown substantial advantages by allowing engines to operate near their peak efficiency. According to the recent annual progress report from the U.S. Department of Energy, using advanced combustion modes has the potential to increase the fuel efficiency of heavy duty engine to as high as 55%, and that of the light-duty vehicle to the range of 35% to 50%.
