Equipping an internal combustion engine with an exhaust turbo supercharger increases the output of the internal combustion engine, so when this exhaust turbo supercharged internal combustion engine is installed in a vehicle such as a car,
The maximum speed of the vehicle may be higher than if it were equipped with a non-supercharged internal combustion engine, which could be dangerous.
そこで、従来は、前記の問題を解消するため

規制制御を行うことが行なわれている。 Therefore, in order to solve the above problem, conventionally, as described in Japanese Patent Publication No. 56-10452, etc., a blower in the exhaust turbo supercharger was added to the intake system of the exhaust turbo supercharged internal combustion engine. An intake bypass passage that bypasses the compressor is provided, or an exhaust bypass passage that bypasses the exhaust turbine in the exhaust turbocharger is provided in the exhaust system, so that the vehicle does not exceed a certain speed. When the vehicle speed reaches the maximum speed, the maximum speed is controlled by opening the intake bypass passage or the exhaust bypass passage to reduce the operation of the exhaust turbo supercharger and lower the supercharging pressure.

ことができないのであつた。
However, when the vehicle is near its maximum speed, the boost pressure to the internal combustion engine is quite high, and the combustion chamber temperature is high, increasing the amount of NOx produced. As in the conventional method of lowering the supercharging pressure by opening the intake bypass passage or the exhaust bypass passage, it has been impossible to suppress the amount of NOx generated in the operating range near the maximum speed range.
また、前記のように吸気パイパス通路又は排気
バイパス通路を開放したとき、内燃機関における
出力が急激に低下するから、車両の運転性能及び
乗り心地が悪化するのであつた。 Furthermore, when the intake bypass passage or the exhaust bypass passage is opened as described above, the output of the internal combustion engine is rapidly reduced, resulting in deterioration of the driving performance and ride comfort of the vehicle.

In order to achieve this object, the present invention provides an internal combustion engine equipped with an exhaust turbo supercharger mounted on a vehicle with an exhaust gas recirculation device that operates to recirculate part of the exhaust gas to the intake system. The device is configured to operate when the speed of the vehicle exceeds a predetermined value, and is provided with means for delaying the operation of the exhaust gas recirculation device.

制できるのである。
When the vehicle temperature exceeds a certain level, the exhaust gas recirculation device operates and exhaust gas is recirculated to the intake system.This recirculation of exhaust gas to the intake system slows down combustion in the combustion chamber, which reduces internal combustion. While it is possible to prevent the engine's output from decreasing and the vehicle speed to increase any further, it is also possible to suppress the generation of NOx in this operating range.
しかし、前記排気ガス還流装置の作動による排
気ガスの吸気系への還流が急であると、内燃機関
における出力が急速に低下することにより、車両
の運転性能及び乗り心地が悪化することになる。 However, if the exhaust gas recirculates into the intake system due to the operation of the exhaust gas recirculation device, the output of the internal combustion engine rapidly decreases, resulting in deterioration of the driving performance and ride comfort of the vehicle.
これに対して本発明は、前記排気ガス還流装置

の急激な低下を回避できるのである。 In contrast, the present invention is provided with a delay means for the operation of the exhaust gas recirculation device, and due to the existence of this delay means, the operation of the exhaust gas recirculation device is delayed and the exhaust gas is transferred to the intake system. Since the recirculation can be carried out gradually, a sudden drop in the output of the internal combustion engine can be avoided.

段を設ける。 The suction passage 12 to the blower compressor 6 in the exhaust turbo supercharger 4 is provided with a negative pressure generation point such as a ventilate 34, and a passage 35 is connected between the negative pressure generation place and the negative pressure transmission passage 32. (In this case, the passage 35 from the negative pressure generation point
is a passage 30 connecting the exhaust pressure regulating valve 18 and the exhaust gas recirculation control valve 17, or the exhaust gas recirculation control valve 1
7), in said passage 35 is associated a vehicle speed sensor 36 of the vehicle, which operates to open said passage 35 when the vehicle speed in the vehicle reaches its maximum speed. valve 37
will be established. Furthermore, delay means such as a restrictor orifice 38 and a check valve 39 which opens only in the direction toward the negative pressure transmission passage 32 are arranged in parallel in the passage 35.

発生を抑制できるのである。 In this configuration, in the idling state with the throttle valve 10 closed, the negative pressure port 33 of the carburetor 9 is located upstream of the throttle valve 10, and no negative pressure is generated in the negative pressure port 33, so that the exhaust gas Pressure chamber 20 in reflux control valve 17
Therefore, the exhaust gas recirculation control valve 17 remains closed and the exhaust gas is not recirculated to the intake system, but when the throttle valve 10 is opened, the negative pressure port 33 is Negative pressure is generated, and after this negative pressure is appropriately adjusted by the exhaust pressure regulating valve 18 according to the exhaust pressure at that time in the internal combustion engine, it is transmitted to the pressure chamber 20 in the exhaust gas recirculation control valve 17. Since the valve body 19 opens, the exhaust gas is recirculated to the intake system, thereby suppressing the generation of NOx in this operating range.

Since the negative pressure generated in the negative pressure port 33 decreases to approach atmospheric pressure, the exhaust gas recirculation control valve 17 is closed and the recirculation of exhaust gas to the intake system is cut off, while the exhaust gas from the internal combustion engine 1 is As the amount increases, the rotation of the exhaust turbo supercharger 4 becomes faster and supercharging is performed. In this case, the supercharging pressure in the intake system is not transmitted to the pressure chamber 20 in the exhaust gas recirculation control valve 17 because the check valve 31 provided in the negative pressure transmission passage 32 is closed.

発生を抑制できるのである。 During this supercharging operation, if the vehicle speed reaches a dangerous maximum speed due to the opening of the throttle valve 10 becoming larger or the load on the vehicle decreasing, etc., the blower in the exhaust turbo supercharger 4 The pressure chamber 20 in the exhaust gas recirculation control valve 17 is opened by opening the valve 37 in the passage 35 from the negative pressure generation point such as the ventilate 34 in the suction passage 12 to the compressor 6 so as to communicate with the passage 35. Since the negative pressure at the negative pressure generating point acts on the valve body 19 and opens the valve body 19, the exhaust gas is returned to the intake system, and due to the return of exhaust gas to the intake system, the fuel in the carburetor 9 As the supply amount decreases, combustion in the combustion chamber slows down, resulting in a decrease in output, and regulation can be controlled to prevent the vehicle speed from increasing any further, while also suppressing NOx generation in this operating range. It is.
しかし、このように吸気系への排気ガスの還流

還流を急激に開始すると、内燃機関の出力が急に
低下することによつて、車両の運転性及び乗り心
地が悪化する。 However, when controlling the maximum speed by recirculating exhaust gas to the intake system, if the recirculation of exhaust gas suddenly starts, the output of the internal combustion engine will suddenly decrease, which will affect vehicle drivability. Ride comfort deteriorates.

A delay means is provided, so that the negative pressure at the negative pressure generating point is not immediately transmitted to the exhaust gas recirculation control valve 17 even when the valve 37 opens, but the exhaust gas recirculation is gradually controlled by the restriction by the throttle orifice 38. This is transmitted to the valve 17, and the exhaust gas recirculation control valve 17 gradually opens, making it possible to avoid a sudden drop in the output of the internal combustion engine.
