A diagnosis apparatus of a fuel supply system includes an operation state detector, an air-fuel ratio sensor, a fuel injection amount calculator, a threshold value table, an abnormality information acquiring device, and an abnormality determining device. In the threshold value table, operation ranges of an internal combustion engine are provided based on an engine speed and a throttle opening. In the threshold value table, a lean side threshold value and a rich side threshold value of an air-fuel ratio correction factor to determine abnormality of the fuel supply system are set beforehand for each of the operation ranges. The abnormality information acquiring device is configured to determine whether the air-fuel ratio correction factor has exceeded the lean side threshold value or the rich side threshold value extracted from the threshold value table according to an operation state so as to acquire abnormality information.

A fuel injection amount calculation method calculates a fuel injection amount to an internal combustion engine of a vehicle. The method can include calculating a relative intake pressure which is a difference between an intake pressure peak of intake air upon intake starting of a cylinder of the internal combustion engine and an intake pressure bottom of the intake air upon intake ending. The method can also include calculating the fuel injection amount based on the relative intake pressure.

Fuel injection amount calculation method and fuel injection controlling apparatus

A fuel injection control device includes a throttle opening read timing setter that sets the timing at which a throttle opening is read. The setter is triggered to detect the throttle opening used for calculation of a basic injection amount by the start of calculation timing of the basic injection amount (FICAL) if the FICAL is at the position corresponding to a toothless part of a crank pulsar rotor. The setter detects the throttle opening based on crank pulse interrupt according to a crank pulse if the FICAL is at a position other than the position corresponding to the toothless part.

A method of processing wheat flour that without detriment to secondary processability, improves the flavor and palate feelings thereof; processed wheat flour obtained by the processing method; and food utilizing the processed wheat flour. The method is characterized in that 10 to 55 pts&#xb7;wt. of ethyl alcohol is homogeneously dispersed in 100 pts&#xb7;wt. of wheat flour under such conditions that the total water content is &#x2266;20 wt. %, followed by evaporation of ethyl alcohol therefrom at &#x2266;50&#xb0; C.
