u2033 u2033 via at least one electronic driver the control system 26 u2033 u2033 is adapted to monitor engine operating parameters via various sensors not shown to control an injection timing an injection duration and an injection rate of the injectors 140 142 160 162 180 182 and a fuel ratio of the first fuel 21 u2033 u2033 to the second fuel 31 u2033 u2033 accordingly the instantaneous demand of the ratio of each fuel and injection type and any combinations thereof up to all six injectors 140 142 160 162 180 182 can be controlled in real time by the control system 26 u2033 u2033 an ignition coil 38 u2033 u2033 may be disposed in the combustion chamber 14 u2033 u2033 of the cylinder 10 u2033 u2033 the ignition coil 38 u2033 u2033 enhances an ignition timing control of the engine at certain conditions such as during cold start and low load operation for example since operation of the fuel injection 8 for a cylinder 10 of an internal combustion engine illustrated in fig1 is substantially similar to the fuel injection system 8 u2032 8 u2033 8 u2032 u2033 8 u2033 u2033 illustrated in fig2 thru 5 for simplicity only the operation of the fuel injection system 8 will be described hereinafter an operation is discussed herein below for a four stroke internal combustion engine it is understood that the above.
