本発明は、過給機付エンジンにおいて加速時に燃料を増
量するようにした燃料供給装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a fuel supply device for increasing the amount of fuel in a supercharged engine during acceleration.

にした装置が知られている。(Prior art) Controlling the amount of fuel supplied according to engine operating conditions has been practiced for a long time, and even in supercharged engines that have a supercharger in the intake passage upstream of the throttle valve, for example, As shown in Publication No. 55-98626,
A device is known that controls fuel injection fJJffi from a fuel injection valve based on detection of an intake air amount by an air flow meter, etc.
ところで、一般にエンジンの加速時においては、スロッ

するため、特開昭５６−１５４１３２号公報に示づ−さ
れるように、加速時に、アクセルペダルの踏込み速度等
に応じて燃料噴射量を増量させるようにした装置も知ら
れている。By the way, when an engine is accelerating, the flow rate and flow velocity of intake air increase rapidly as the throttle valve is opened, and the fuel supply amount is controlled based on the detection of the intake air amount. Since the fuel cannot keep up with the increase in intake flow velocity by simply increasing the intake flow rate, there is a problem that the air-fuel mixture becomes temporarily lean (and the output decreases). As shown in FIG. 1, there is also known a device that increases the amount of fuel injection during acceleration according to the depression speed of the accelerator pedal, etc.
しかし、過給機付エンジンにこのような装置を用いた場
合、加速が行われるまでの運転経過によっては、必ずし
も加速時の燃料増量値が吸入空気量の増加に合致しない
という問題が残されていた。However, when such a device is used in a supercharged engine, there remains the problem that the fuel increase value during acceleration does not necessarily match the increase in intake air amount, depending on the operating process before acceleration occurs. Ta.

状態から減ｊ＊された直後は過給機が慣性で回転してい

れるときはスロットルバルブ上流の圧力が比較的低くな
るというように、加速時までの運転経過の相違により、
加速開始時のスロットルバルブ上流の圧力が種々異なる
。そして、この圧力に依存して吸入空気量が変動する。In a supercharged engine, for example, immediately after a high load or operating condition, the supercharger is rotating due to inertia, so when acceleration is performed immediately after deceleration, the throttle valve upstream The pressure upstream of the throttle valve is relatively low, and the pressure upstream of the throttle valve is relatively low when JJni ili is performed from a state where the turbocharger is not operating due to continuous load operation. Due to differences in driving history,
The pressure upstream of the throttle valve at the start of acceleration varies. The amount of intake air varies depending on this pressure.
従って、アクセルペダルの踏込み速度に応じて燃料噴射
量を制御°りるだけでは、加速時の吸入空気量に応じた
適正な増量値を得ることができなかった。Therefore, by simply controlling the fuel injection amount in accordance with the depression speed of the accelerator pedal, it has not been possible to obtain an appropriate increase value in accordance with the intake air amount during acceleration.

The engine is equipped with an acceleration detecting means for detecting when the engine is accelerating, a pressure detecting means for detecting the pressure between the thrower valves and the supercharger, and a fuel adjusting device U9. This fuel supply device increases the amount of fuel supplied to the engine (during acceleration) at a predetermined rate upon receiving the outputs of both of the detection means, and increases the increase rate as the pressure increases. By this, the fuel i13+ 1!' during acceleration is adjusted to match the amount of intake air that depends on the pressure mentioned above.
The configuration is such that the I-inversion value is corrected.

る。In this case, in the combustion Llt device 30, the fuel increase rate during acceleration determined by the acceleration correction calculation circuit 31 is determined by the correction circuit 34 according to the pressure between the throttle valve 6 and the supercharging member 7. This is corrected, and an appropriate fuel increase rate commensurate with the increase in intake air amount during acceleration can be obtained. In other words, in a supercharged engine, due to the intake inertia of the supercharger 7, the above-mentioned pressure at the start of acceleration will change if the operating progress until acceleration is different, so the pressure at the start of acceleration will change. and the amount of intake air sent to the combustion chamber 2.
It varies depending on the pressure, and for example, when acceleration is performed immediately after deceleration from a high-load operating state, the intake air amount becomes larger than when acceleration is performed from a constant-speed operating state. On the other hand, the fuel increase rate is corrected according to the above pressure, and the higher the above pressure is, the larger the fuel increase rate becomes. Correspondingly, an appropriate air-fuel ratio will be provided.

This is similar to the embodiment shown in the figure. According to this embodiment, the pressure between the throttle valve 6 and the supercharger 7 is determined as a relative pressure to the pressure downstream of the throttle valve 6, and this relative pressure is more accurately determined as the intake air amount. In order to accommodate this, the correspondence between the increase in intake air amount during acceleration and the fuel increase rate is increased.
