| Abstract: | Based on the design concept of fuel mixing ratio real-time optimization,an on-line mixing mode,which could fast adjust the proportion between diesel and dimethyl ether(DME),was put forward.The PWM driving mode of electronic-controlled injector for the on-line mixing was tested and analyzed.The result indicates that the increase of driving voltage can improve the injector response speed.The opening pulse width and PWM duty ratio determine the current magnitudes of opening and duration periods.Through the exp... |
