Development and Research on Air Turbulence In-cylinder for Heavy-duty DI Diesel Engine

Controlling air turbulence in cylinder is in favor of improving the economy and emission character of heavy duty DI diesel engine.Last years, the technologies of heavy duty DI diesel engine have been developed at very fast speed. The authors tracked and surveyed these technologies and investigated into the effects of the new technologies on air turbulence in cylinder. In terms of the formation and identity of air turbulence in cylinder, the authors point out that it is a key give priority to high pressure injection, proper air turbulence movement in cylinder and proper combustion chamber structure,for heavy duty DI diesel engine to obtain and advanced performance.
