It opens into the intake passage 18 upstream from this point, and the other end opens into the combustion chamber 4, and the opening is formed in the valve seat 27.
副吸気路２６の下流側内壁には含油軸受材よりなる案内

供給される。Next, to explain the operation of this embodiment, during low load operation of the engine in which the throttle valve 23 of the carburetor 14 is held at a low opening position, during the intake stroke of the engine, the inside of the combustion chamber 4 is lowered as the piston 3 descends. When the main intake valve 9 is opened by the cam 7a moving as the piston 3 descends and the rocker arm 8a, this negative pressure passes through the main intake passage 5 and reaches the low-speed nozzle of the intake passage 18. 21, 22, low speed nozzle 21゜2
Fuel suitable for low-load operation is sucked out from the combustion chamber 2, and the resulting air-fuel mixture is supplied into the combustion chamber 4 through the main intake passage 5.

拌する。At the same time, the large negative pressure within the combustion chamber 4 acts on the lower surface of the valve portion 28b of the auxiliary intake valve 28, and moves the valve body 35 against the valve spring 32 to the open position, that is, the valve portion 28b is spaced apart from the valve seat 27. The air purified by the air cleaner 16 passes through the sub-intake passage 26 and the hollow part of the valve rod 28a to the blowhole 30, due to the effect of the negative pressure. The air is injected into the combustion chamber 4 from the nozzle holes 30, 30..., and the negative pressure in the combustion chamber 4 is high, especially when the engine is operating at low load, so the amount of air jetted out from the nozzle holes 30, 30... is large, and therefore the flow rate is low. Moreover, since each blowhole 30 is oriented in the tangential direction of the outer circumference of the valve rod 28a, the air injected into the combustion chamber 4 creates a vortex, which causes the spark plug 1
The burnt gas remaining around the 0 electrode is scavenged all at once, and the air-fuel mixture taken in from the main intake passage 5 is diluted and stirred.

未燃焼成分の含有量が低減する。Next, the main intake valve 9 closes in conjunction with the rise of the piston 3 in the compression stroke, and when the pressure in the combustion chamber 4 increases, the auxiliary intake valve 28 closes due to that pressure and the elastic force of the valve spring 32. When a spark discharge occurs at the spark plug 10 at the end of the compression stroke, the air around it has already been scavenged as described above, so ignition is sure to occur, and since the air-fuel mixture is stirred as described above, , even if the air-fuel ratio is lean, good combustion occurs, and as a result, exhaust passage 1 in the next exhaust stroke
The content of unburned components such as carbon monoxide and hydrocarbons in the exhaust gas discharged into the engine is reduced.

副吸気路２６から燃焼室４への空気の噴入は差程必要で
なく、それに対応するように吸入行程時、副吸気弁２８
は開放しないか、若しくは僅かに開放する。Next, during high-load operation of the engine when the throttle valve 23 of the carburetor 14 is opened to a high opening degree, combustion is originally performed well due to the improvement in the charging efficiency in the combustion chamber 4.
It is not necessary to inject air from the auxiliary intake passage 26 into the combustion chamber 4, and in response to this, the auxiliary intake valve 28 is
does not open or opens slightly.

部２８ｂ上面に導入される吸気負圧が、機関の高負荷運
転時には特に増大変化して副吸気弁２８に比較的大きな
閉成力として作用することによる。This is because the throttle valve 23 is opened to a high degree, so the negative pressure generated in the combustion chamber 4 during the intake stroke is low, and the sub-intake valve 28
The opening force exerted on the carburetor 1 is significantly reduced, and the
The negative intake pressure introduced into the upper surface of the valve portion 28b of the intake valve 28 from the intake passage 18 of No. 4 through the auxiliary intake passage 26 increases and changes particularly during high-load operation of the engine, causing a relatively large closing of the auxiliary intake valve 28. By acting as a force.

絞り弁２３より上流側に開口している関係上、弁部２８

弁２８に閉成力としては殆ど作用しない。Note that during low-load operation of the engine, the upstream end of the auxiliary intake passage 26 opens upstream from the throttle valve 23, so the valve portion 28
The negative intake pressure acting on the upper surface b is small and hardly acts on the sub-intake valve 28 as a closing force.

きる。As described above, according to the present invention, the auxiliary intake valve 28 is constituted by a negative pressure responsive valve that is sucked and opened when a negative pressure of a certain value or more is generated in the combustion chamber 4 during the intake stroke of the engine. During low load operation of the engine, where it is difficult to achieve good combustion of the air-fuel mixture due to a decrease in efficiency, the sub-intake valve 28 opens wide due to the large negative pressure generated in the combustion chamber 4 during the engine intake stroke, causing combustion to flow from the sub-intake passage 26. Air can be injected into the chamber 4, and the air mixture is agitated and moderately diluted by the air injection, and the scavenging air around the ignition plug works together to make it possible to burn the mixture to dilute it. can reduce unburned components.
しかも副吸気弁２８のだめの従来のような複雑な動弁機
構が不要になるので、機関の構造が著しく簡単になると
共に製作が容易である。Moreover, since the complicated valve operating mechanism of the sub-intake valve 28 as in the prior art is not required, the structure of the engine is significantly simplified and manufacturing is easy.

薄化燃焼を安定させることができる。In particular, the sub-intake valve 28 has a large number of blowholes 30 oriented in the tangential direction of the outer circumferential wall thereof, and is slidably connected to the inner wall of the sub-intake passage 26 and engaged with the inner wall to form the blowholes. 30 and an open position where the engagement is released and the nozzle hole 30 is opened to the combustion chamber 4; and a valve spring 32 that always springs the valve toward the closed position side, and the valve body 35 resists the valve spring 32 when a negative pressure of a certain value or more is generated in the combustion chamber 4 during the intake stroke of the engine. Since the air is sucked toward the open position, the air injected into the combustion chamber 4 from each jet hole 30 of the auxiliary intake valve 28 is directed toward the tangential direction of the outer circumference of the valve body 35, creating a strong swirling flow. As a result, the above-mentioned mixture stirring and scavenging around the spark plug can be performed sufficiently reliably, and the lean combustion of the mixture can be stabilized.

でコストを低減することができる。Furthermore, the upstream end of the auxiliary intake passage 26 is opened to the intake passage 18 of the carburetor 14, and only the air purified by the air cleaner 16 of the carburetor 14 can be introduced into the combustion chamber 4 from the auxiliary intake passage 26. Therefore, there is no need to provide a special air cleaner for the auxiliary intake passage 26, and the structure is simple and costs can be reduced.

という副吸気弁２８の所期の作動を確実に得ることがで
きる。Moreover, since the upstream end opening of the auxiliary intake passage 26 is located upstream of the throttle valve 23 in the low opening position of the intake passage 18, the opening part at the upstream end of the auxiliary intake passage 26 is located upstream of the throttle valve 23 in the low opening position. Air with a large negative pressure can be introduced, and this negative pressure can act as a relatively large closing force on the valve body 35 of the auxiliary intake valve 28, so that the combustion chamber is closed during high-load operation. Due to the small amount of negative pressure generated within 4,
The closing tendency of the auxiliary intake valve 28 during the same operation can be strengthened, and as a result of the above, the auxiliary intake valve 28 is largely opened during low load operation of the engine, and its opening is narrowed in response to changes in the load. The desired operation can be reliably obtained.
