Problem The present invention provides a fuel injection control device of a multiple-kind fuel internal combustion engine which can perform a stable optimum fuel supply control in response to mixing ratios of multiple-kind fuels and, at the same time, shortens the starting time and prevents the covering of the plug.
Means for Resolution A ROM 23 of an ECU 10 stores a plurality of reference fuel injection quantity maps corresponding to mixture concentrations of multiple-kind fuels. A control program of the CUP 21 stores which map is used out of the plurality of reference fuel injection quantity maps in an EEP-ROM 24, performs a starting control of an engine using the reference fuel injection quantity map which is used immediately before stopping previous time at the time of initiating the starting based on the stored maps and, at the same time, performs the starting control by gradually increasing the fuel injection quantity until the starting of an engine is finished. Alternatively, the control program performs a starting control using the map with the least fuel injection quantity, i.e. the smallest ethanol concentration at first and then changes over to the next map with a larger fuel injection quantity until engine start. |
