AbstractA brief review of dual fuel engine technology is given in this paper from the point of view of technology and market in China.A sequencial port injection,lean burn,fully electronically controlled dual fuel engine was proven to be the most suitable solution to the market requirement――clean and economical.It is also a important advantage in China that the engine could operate either on CNG or on 100% diesel fuel when gas supply is interrupted.Optimization of combustion process for the purpose of low emissions and high fuel economy was carefully conducted by calibration of natural compressed gas injection quantity and timing and quantity of diesel fuel injection at all operating condtions.The effects of airgas ratio λ on NOx,PM,THC and CO were given and analyzed.
