In consideration of the fact that fuels with various alcohol concentrations will be used, the system detects the alcohol concentration in the mixed fuel and increases the amount of fuel according to the alcohol concentration to improve the mixture at startup or warm-up. The purpose is to prevent overconcentration.

A known alcohol sensor, such as one that directly converts changes in alcohol concentration into changes in current, can be used. The alcohol sensor 3 signal is sent to the microcomputer (CPU')

ることにより検出することができる。FIG. 2 shows an example of the control characteristics of the fuel supply amount at the time of starting by the CPU 7, and shows the injection time with respect to the cooling water temperature at the time of starting. In the embodiment shown in FIG. 2, the fuel injection valve 11 is activated at the time of starting the internal combustion engine, that is, from the time when the ignition switch (not shown) is turned on and the ignition coil 8 is energized until the engine completely explodes. This shows the fuel injection time (valve opening timing). That is, at the time of starting the internal combustion engine, the injection time with respect to the engine coolant temperature when the alcohol concentration is zero is programmed in advance as shown by the broken line in the figure. The higher the alcohol concentration in the fuel, the shorter the injection time (as shown by the solid line in the figure) shifts the curve of cooling water temperature versus injection time. The lower the alcohol concentration, the more the curve of cooling water temperature vs. injection time shifts to the direction of increasing the injection time, as shown by the broken line in the figure.In addition, the rotation of the engine must be detected to determine when the engine is fully detonated. It can be detected by

時点としてもよい。Fig. 3 shows the fuel supply amount characteristics at the time of starting and after the engine complete explosion, where the horizontal axis is time and %TI is the time when the ignition switch (not shown) is turned on and the ignition coil 8 is energized; T2 is the point at which the engine completely explodes. The vertical axis is the fuel increase ratio, and the steady state (state where the fuel is not increased at a predetermined air-fuel ratio) is rl, o J. Fuel increase ratio at startup and after startup (when alcohol concentration is zero)
The duration of the increase (after complete detonation) is programmed as shown in the broken line in the figure, and the higher the alcohol concentration (the higher the alcohol concentration, the greater the shift in the direction shown by the solid line in the figure, that is, the direction in which the increase ratio and duration of increase are decreased) Conversely, as the alcohol concentration decreases, the shift shifts in the direction of the broken line in the figure, that is, in the direction of increasing the increase ratio and increase duration. Note that T2 is the point at which the starter switch (not shown) is turned OFF. You can also use it as

ことが望ましい。FIG. 4 shows the fuel supply amount characteristics when the internal combustion engine is cold, that is, during warm-up operation, where the horizontal axis represents the cooling water temperature and the vertical axis represents the fuel increase ratio. If the alcohol concentration of the fuel is zero, program the fuel increase ratio when the engine is cold (for example, when the cooling water temperature is 70°C or less) as shown in the broken line in the figure, and when the alcohol concentration is high. The more you become,
The fuel increase ratio is shifted in the direction of the solid line in the figure, that is, in the direction of decreasing the fuel increase ratio. Conversely, the lower the alcohol concentration, the more the fuel increase ratio is shifted in the direction of the broken line in the figure, that is, in the direction of increasing the fuel increase ratio. It is preferable to combine the characteristics shown in FIG. 4 and the characteristics shown in FIG. 2, and to perform the control as shown in FIG. 2 after the engine starts and before the engine is completely heated, and to perform the control as shown in FIG. 4 after the engine is completely detonated and before warming up.

ガス中の有害成分を減少する効果がある。According to the present invention, even when fuels with various alcohol concentrations are used in internal combustion engines that use alcohol-mixed fuel, the fuel at startup and/or warm-up is adjusted depending on the alcohol concentration. Since the supply is controlled, when the alcohol concentration in the fuel is high, the fuel increase is shifted to a lower value, so the air-fuel mixture does not become too rich, and therefore the startability and drivability of the engine are improved. This has the effect of reducing harmful components in exhaust gas.
