The fuel amount determiner has a feedback control mode in which the fuel amount determiner determines a running state reference coefficient corresponding to a running state detected by a running state detector based on a first correspondence stored in the memory, determines a running state compensation coefficient corresponding to the running state detected by the running state detector based on a second correspondence stored in the memory, determines a feedback compensation coefficient used to cause an air-fuel ratio to reach a value closer to a theoretical air-fuel ratio based on an output of the air-fuel ratio sensor, and determines the fuel command value using a formula including the determined running state reference coefficient, the determined running state compensation coefficient, and the determined feedback compensation coefficient.

摘要： An ECU is used in a motorcycle including an engine E, which combusts in a combustion chamber a blended fuel in which gasoline and ethanol are blended, and a fuel injection device for injecting a fuel with a predetermined fuel injection amount such that an air excess ratio in the combustion chamber is a first predetermined value when an ethanol concentration of the blended fuel is zero. The ECU executes O2 feedback control based on an O2 concentration derived from an output of an O2 sensor. Further, the ECU calculates an actual fuel compensation ratio by dividing a fuel injection amount after the O2 feedback control by a predetermined fuel injection amount, and estimates the concentration of the alternative fuel based on this actual fuel compensation ratio and a first predetermined value stored in the ECU.
