Electronic fuel injection device using phase difference of 6 cylinder engines for automobiles

摘要

This research is about the vehicle fuel injection device, especially the electronic fuel injection device which can sense and output the fuel injection time of the six cylinder four administrative engine.in other words.On the electronic fuel injection unit,The first coil (L1) outputting a certain value of peak to peak voltage (v1p-p),A second coil L2 for outputting a peak-peak voltage V2p-p having a predetermined magnitude in phase with the first coil L1 at 60 °;The second coil (L2) and,The 3φ sensor made up of the third coil L3 outputting a constant peak-peak voltage (V3p-p) with a phase of 60 ° is provided to determine the ignition timing of six cylinders by the peak-peak voltage value of the coil. ,Determine the injection time in order to reduce the cost and effective injection.
