Abstract:
A fuel injection control device for use with an internal combustion engine, the engine comprising a plurality of cylinders which sequentially perform a combustion of fuel and a starter motor which cranks up the engine, each of the cylinders having an intake port and a fuel injector which injects fuel into the intake port, and sequentially performing an intake stroke, a compression stroke, a expansion stroke and an exhaust stroke, the device comprising:a first sensor which detects a start of the starter motor; a second sensor which detects a cylinder in a specific position in a specific stroke and generates a corresponding signal: and a programmable controller programmed to: execute a cylinder-stroke identification identifying a present stroke of each cylinder based on the signal generated by the second sensor; and control the fuel injectors to simultaneously perform a primary fuel injection for a cylinder in the intake stroke and for a cylinder in the exhaust stroke simultaneously, on the first execution of the cylinder-stroke identification.
