出力向上が達成できなくなることがある。 In conventional internal combustion engines, a compressor is installed in the middle of the intake passage, and the rotation of this compressor pressurizes the intake air flowing through the intake passage, increasing its filling efficiency and increasing engine output. A motorized internal combustion engine is known, but when the throttle valve in the intake passage of such an engine is opened and the supercharger is activated to supercharge pressurized air and the engine is running at output speed, When the throttle valve is suddenly closed, the supercharged pressurized air in the intake passage instantaneously flows back upstream through the compressor, causing the flowing pressurized air to flow inside the intake passage, especially in the compressor. When the engine is operated at output again due to flow disturbance such as separation phenomenon, sufficient supercharging effect may not be obtained and the desired output increase may not be achieved.
そこで本発明は吸気通路内の絞り弁の急閉時に

提供することを主な目的とするものである。 Therefore, the present invention prevents the supercharged air from flowing backward even when the throttle valve in the intake passage is suddenly closed, thereby preventing a decrease in engine output, and also accurately adjusts the inflow air density at the compressor inlet. A supercharger that detects this and inputs it as a correction signal to an electronic control device such as a microcomputer to accurately correct the amount of fuel injection and ignition timing according to the amount of pressurized intake air. Its main purpose is to provide an internal combustion engine with an internal combustion engine.

出する。 The intake passage 9 is provided with various sensors for controlling the amount of fuel injected from the fuel injection nozzle 19. That is, in the intake passage 9, between the compressor C and the one-way valve 24, a temperature sensor T1 and a first pressure sensor P1 for detecting the temperature and pressure at the inlet of the compressor C are connected, and these act as a reed valve.

The basic fuel injection amount and ignition timing are determined by inputting the rotational speed of the internal combustion engine and its boost negative pressure (low engine load operating range) or throttle opening (engine high load operating range). The actual fuel injection amount and ignition timing are controlled by correcting the amount of intake air based on the air density detected from the pressure and temperature of the engine and the boost pressure on the downstream side.

止し、充填効率を高めることができる。 The supercharged internal combustion engine is now operated, and during its exhaust stroke, the exhaust gas discharged from the combustion chamber 4 to the exhaust passage 10 passes through the turbine T, and at this time gives exhaust energy to the turbine wheel 14. This causes the turbine wheel 14 to rotate and drive the compressor wheel 13 via the rotating shaft 15.
The air taken in is pressurized by the compressor C and sent to the pre-chamber 21, and then the throttle valve 20
After the flow rate is adjusted by the fuel injection nozzle 19
The fuel is mixed with the injected fuel from the engine and supplied to the combustion chamber 4 during the intake stroke of the engine. During engine operation, when pressure pulsations are generated in the intake passage 9 due to intermittent operation of the intake valve 7, etc., the pressure pulsations are attenuated by the presence of the pre-chamber 21 and the resonance chamber 23.
This can prevent the surging phenomenon of the compressor C and improve the filling efficiency.

ことができる。 By the way, as mentioned above, when the throttle valve 20 is suddenly closed while the throttle valve 20 is opened and the compressor C is activated to supercharge the engine, it is assumed that the reed valve 24 is inserted into the intake passage 9. If it does not exist, the pressurized air in the intake passage 9 that is being supercharged will momentarily flow backwards in the intake passage 9, and at that time, turbulence will occur in the flow, such as separation of flowing air within the compressor C, etc. However, when the throttle valve 20 is opened again, the supercharging effect may be impaired to some extent and the desired output may not be obtained.
By providing the reed valve 24 in the internal combustion engine, the reed valve 24 prevents the intake air from flowing backward when the throttle valve 20 is suddenly closed. It is possible to obtain high output during the period.

なこともない。 Furthermore, when the throttle valve 20 is suddenly closed, a portion of the intake air flowing through the intake passage 9 flows backwards and reaches the muffler 26 through the small-diameter muffling passage 25, causing abnormal noise when the throttle valve 20 is suddenly closed. is effectively suppressed by this muffler 26. In this case, the silencer 26 is
Since the muffler 26 is connected to the small-diameter muffler passage 25 which is branched into the muffler passage 25, the muffler 26 does not obstruct the intake air flowing into the suction passage 9 and cause a decrease in engine output. By making the diameter as small as possible compared to the intake passage 9, the muffler can be made compact. In addition, this sound deadening passage 25
The presence of the engine brake does not affect the effectiveness of the engine brake.

Since it is provided in the suction passage 9 between the reed valve 24 and the compressor C, the pressure and temperature at the inlet of the compressor C after passing through the reed valve 24 can be detected, and the pressure and temperature due to the presence of the reed valve 24 can be detected. There is no need to compensate for temperature changes.

達成させ、高出力を発揮させることができる。 As described above, according to the present invention, in a supercharged internal combustion engine in which a compressor is installed in the intake passage, a one-way valve such as a reed valve is provided in the intake passage, so that when the throttle valve is suddenly closed, The desired supercharging effect can always be achieved and high output can be achieved without causing any disturbance to the flow of intake air such as separation of the intake air within the intake passage, particularly within the compressor.

行うことができる。 In addition, an intake air density detection sensor such as a pressure sensor or temperature sensor is installed in the intake passage between the one-way valve and the compressor, so the air density is detected from the atmospheric pressure and outside temperature of the intake air of the internal combustion engine, and the intake air amount is When performing detection correction, the pressure and temperature at the inlet of the compressor can be used as a reference, and there is no need to make corrections due to changes in pressure and temperature before and after the one-way valve. Despite the provision, the intake air amount can be easily and accurately detected and corrected.
