【Example】

Example 1. An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of the present invention. In the figure, parts corresponding to those in FIG. 8 are designated by the same reference numerals, and detailed description thereof will be omitted. Reference numeral 15A is an alternator that is connected to a movable part of the engine 1 and generates a required electric power, 20 is an intake air amount signal processing device, and this intake air amount signal processing device 20 outputs the output of the accelerator opening sensor 6 and Although not shown, it is involved in fuel control and a control signal 22 for controlling the rotation speed of a motor for driving an air pump, which will be described later, based on an output signal of a vehicle speed sensor, an engine speed sensor, and an input signal 21 including a gear ratio signal. The intake air amount signal 23 is generated.

Reference numeral 24 is provided in the intake passage 2 for the engine 1
Reference numeral 25 is an air pump that regulates the intake air flowing through the motor, and 25 is a motor that drives the air pump 24 in response to a control signal 22 from the intake air amount signal processing device 20. Reference numeral 26 is a fuel signal processing device. The fuel signal processing device 26 receives the intake air amount signal 23 of the engine based on the drive rotation speed of the motor 25 from the intake air amount signal processing device 20 and the intake air amount signal 23. A fuel signal for driving the fuel injection valve 12 to control the fuel is generated based on an input signal 27 including outputs of an air temperature sensor, an atmospheric pressure sensor, a water temperature sensor, an O ₂ sensor, an engine speed sensor, and the like. Also, although not shown, an ignition signal for controlling the ignition of the spark plug is generated.

Next, the operation will be described. Generally, in the case of a 4-cycle engine, for example, the so-called intake manifold pressure P _i (atmospheric pressure), which is the pressure in the intake passage 2, is
The intake air amount of the engine 1 q (L / s), the engine speed n _e (vpm), when the exhaust amount of the engine 1 and V (L), is expressed by the following equation.

P _i = (2 × q) / {(n _e / 60) × V} (1)

On the other hand, the intake air amount q is given by the following equation as a function of n _m , where n _m (vpm) is the number of rotations of the motor 25 that drives the air pump 24.

Q = f (n _m ) ... (2)

Therefore, the intake manifold pressure P _i in the intake passage 2 can be controlled by controlling the rotation speed n _m of the motor 25 based on the output of the accelerator opening sensor 6 which detects the position of the accelerator pedal 5. As a result, the amount of intake air supplied to the engine 1 is adjusted and the output of the engine 1 can be controlled. Here, when a positive displacement pump such as a roots pump is used as the air pump 24, the intake air amount q is approximately proportional to the motor rotation speed n _m and is represented by the following equation.

Q = K ₁ V _m (3)

In the above equation (3), K ₁ is a constant. Thus, the relationship between the intake manifold pressure P _i and the motor speed n _m is shown from the above equations (1) and (3), for example, as shown in FIG. 2, when the engine speed n _e is used as a parameter. The drive power P _w of the motor 25 in this case is
When the pressure on the suction side of the air pump 24 is P _s , it is expressed by the following equation.

P _w = K ₂ q (P _i −P _s ) (4)

In the above equation (4), K ₂ is a constant. Here, the pressure P _s on the suction side of the air pump 24 is almost atmospheric pressure, and for example, in the case of an engine for automobiles in which partial load operation is frequent, the time during which P _i <P _s is long and P _w <0, that is, The motor 25 will normally operate in the power generation region. This relationship is expressed by the following equation obtained by eliminating q from the above equations (1) and (4).

P _w = K ₃ · _ne · V · P _i (P _i −P _s ) ... (5)

In the above (5), K ₃ is a constant.
Based on this (5), when the displacement V is fixed and the engine speed n _e is used as a parameter, the relationship between the intake manifold pressure P _i and the motor drive power P _w is shown in FIG.

As can be seen from FIG. 3, in the operation in the natural intake (NA) region, the motor 25 performs a power generation operation, the engine speed n _e and the intake manifold pressure P.
_The amount of power generation is determined according to _i . On the other hand, in the supercharging region, the motor 25 is driven and the driving power is rapidly increased as the engine speed n _e and the intake manifold pressure P _i are increased, but within a predetermined range determined by the rating of the motor 25 and the like. Supercharging is also possible. Since the power generation operation is performed during the partial load operation that occupies most of the operation time of the engine 1 as described above, the alternator 15A that generates the required power can be omitted or reduced in capacity.

As described above, in this embodiment, since the intake air amount adjusting means is composed of the air pump 24 and the motor 25, supercharging operation can be easily performed, and power generation operation is performed during partial load operation. It is possible to improve efficiency and reduce weight by eliminating the alternator or downsizing. Further, since the intake air amount signal is obtained from the pump driving speed, the air flow sensor can be omitted, and the configuration is simple and the cost is low. Further, since the intake air temperature is lowered, the filling efficiency is improved and knocking is suppressed.

And are used for fuel control.

In the control method, the intake air amount signal 11a is mainly used, and the failure diagnosis of the intake air amount signal 11a is performed by comparing the intake air amount signal 11a with the signal 23.
On the contrary, it is possible to mainly use the intake air amount signal 23. Although the case of the air flow sensor in the so-called L-JETRO system has been described here, the same effect can be obtained by using the intake manifold pressure sensor in the so-called D-JETRO system.

The speed control valve 13 is used.

In an idle operation region where the intake air amount of the engine is small, the driving rotational speed of the motor 25 is low, and the pulsation of the intake air amount may be a problem. In such an operating region where the required intake air amount is small, stable control is performed by using the idle speed control valve 13 as an auxiliary intake air amount adjusting means that bypasses the air pump 24 provided in the main passage of the intake passage 2. It is possible to drive the car. Although the case where the fuel signal processing device 26 controls the idle speed control valve 13 is described here, the control may be performed by the intake air amount signal processing device 20.

Since it is possible to reduce the weight by downsizing, and because the intake air temperature decreases, it is possible to improve the charging efficiency and suppress the occurrence of knocking.
The accuracy of detecting the intake air amount can be improved. Further, in this embodiment, the idling speed can be stabilized in the idling operation region where the intake air amount of the engine is small.

Example 4. FIG. 6 is a block diagram showing another embodiment of the present invention. In the figure, parts corresponding to those in FIGS. 1 and 8 are designated by the same reference numerals, and detailed description thereof will be omitted.
In the present embodiment, as in the second embodiment, the air flow sensor 11 is used as the intake air amount detecting means, and a plurality of air pumps 24 whose operation phases are mutually shifted in the intake passage 2 are used.
a and 24b are provided, and these are connected to the motor 25.

The motors 25 drive the air pumps 24a, 24 whose operation phases are shifted from each other.
