<p><P>PROBLEM TO BE SOLVED: To improve uniformity of fuel/air mixture supplied to a combustion chamber in a fuel injection device for an internal combustion engine where gas fuel including a plurality of fuel components is used as fuel. <P>SOLUTION: The fuel injection device for the internal combustion engine includes: a fuel injection valve which injects the gas fuel including the plurality of fuel compositions to an intake port; and a mixing ratio estimation device for estimating a mixing ratio of the fuel components in the gas fuel. The mixing ratio of the gas fuel is estimated, and an injection start timing of the gas fuel from the fuel injection valve is set based on an estimated mixing ratio. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
