Generally, when an engine is not sufficiently warmed up, such as in a cold region, a portion of the fuel is not sufficiently vaporized and flows through the intake manifold in a liquid state. The internal combustion engine has four cylinders arranged in series, and the four cylinders are sequentially arranged from one end of the series to the other end as cylinder #1, cylinder #2, cylinder #3,
The #4 cylinder is defined as the intake manifold having four branch ports, the branch port connected to the #1 cylinder is the #1 branch port, the branch port connected to the #2 cylinder is the #2 branch port, and the #3 branch port is the branch port connected to the #2 cylinder. The branch port connected to the cylinder is defined as the #3 branch port, and the branch port connected to the #4 cylinder is defined as the #4 branch port.In the conventional intake manifold, as shown in Fig. 1, liquid fuel flows into the riser section. 1. When flowing into the #1 to #4 branch ports 3, 4, 5, and 6 from the curved passage portions 2 on both sides, it tends to flow outward due to inertia, so the flow flows into the #1 branch port 3 and #4 branch port 6. The amount of fuel flowing in tended to increase. If the distribution of fuel to each cylinder becomes uneven, the plugs in the cylinders receiving a large amount of fuel supply are more likely to smolder, and the cylinders receiving less fuel supply are more likely to cause misfires, and the output performance decreases, resulting in poor fuel efficiency. Because of this problem, various measures have been taken in the past to evenly distribute fuel to each cylinder.

示している。 JP-A No. 52-34117 discloses a device in which a barrier is provided at the bottom of the passage or a step extending in a direction to block the flow of the air-fuel mixture to ensure uniform distribution, while JP-A No. 40-24401 discloses a system in which a barrier is provided at the bottom of the passage or a step extending in a direction to block the flow of the air-fuel mixture to ensure uniform distribution. This disclosure discloses a device that attempts to equalize the distribution by making a difference in the uphill slope of the port.

However, since the device disclosed in Japanese Patent Application Laid-open No. 52-34117 attempts to flow more fuel to the ports on the outer peripheral side, it is not possible to increase the amount of fuel to the ports on the inner peripheral side, which is the purpose of the present invention. It is the opposite of thought,
Barriers and steps are undesirable because they act to increase flow resistance. Furthermore, the method disclosed in Japanese Patent Publication No. 40-24401 makes a difference in the slope of the climb after entering the branch port, so it is not possible to move to another branch port after entering the branch port, so it has the effect of equalizing the distribution. is not good.
本考案は、この対策の一つとして、冷間始動時
における液状燃料の各気筒への分配を均一化する
ために、分岐ポートのみでなく分岐ポートの上流

するものである。 As one of the countermeasures for this problem, this invention aims to distribute fuel not only to the branch port but also to the inner peripheral port on the upstream side of the branch port in order to equalize the distribution of liquid fuel to each cylinder during a cold start. accelerate the transition,
The purpose is to effectively equalize fuel distribution.

In order to achieve this purpose, in the intake manifold for an internal combustion engine of the present invention, the passages from the curved passages on both sides of the riser part to the branch ports downstream thereof are formed with an upward slope. The upward slope of the lower surface of the passage section going from the curved passage section to the #1 branch port and #4 branch port is higher than the upward slope of the lower surface of the passage section going from the curved passage section to the #1 branch port and #4 branch port. The slope is set to be gentle on the upstream side.
また、湾曲通路部の底面には、湾曲の内周側を
外周側より低位とする段差が設けられている。 Further, the bottom surface of the curved passage section is provided with a step that makes the inner circumferential side of the curve lower than the outer circumferential side.

がはかられることになる。
For this reason, the liquid fuel is gathered to the inner circumferential side by the step on the upstream side of the branch point of the branch port,
In addition, since the slope is gentle, more flow tends to flow into the #2 and #3 branch ports, which have lower flow resistance. Conventionally, liquid fuel tends to flow toward the #1 and #4 branch ports, but liquid fuel tends to flow to the #2 and #3 branch ports. A large amount of fuel will also flow to the three branch ports, and distribution to each cylinder will be made more uniform.

１５，１６とから成る。 FIG. 2 shows an intake manifold according to an embodiment of the present invention. In the figure, reference numeral 10 denotes an intake manifold, which is roughly divided into a riser part 11 that changes the air-fuel mixture flowing from the carburetor from a vertical flow to a horizontal flow and heats it during slow cooling, and a riser part 11 that is connected to both downstream sides of the riser part 11. A curved passage section 12 that bends the flow toward the cylinder head side, and #1 to #4 branch ports 13 connected to the downstream side of the curved passage section 12 to branch the flow from the curved passage section 12 and guide it to each cylinder. ,14,
It consists of 15 and 16.

る。 Of these, the riser portion 11 is open toward the top and has a potbell-shaped hole. Riser part 1
The bottom of 1 extends horizontally. Curved passage section 12
extends in a straight line from the riser portion 11 to both left and right sides and toward the cylinder head side, and curves from there to bend toward the cylinder head side. The outer circumferential wall of this curved portion extends outward on both the left and right sides, so that the width of the passage in the horizontal plane of the curved passage portion 12 is expanded. The outer circumferential wall 25 of the curved passage section 12 has a straight section 25a on the downstream side from the riser section 11, followed by a curved section 25b that curves toward the cylinder head side, and further followed by a straight section 25c. The extension lines of the straight portions 25c of the pair of left and right outer peripheral walls 25 are inclined so as to intersect on the cylinder head side. From the curved passage section 12 to the vicinity of the branch points 17 and 18 of the branch port,
A stepped portion 20 that is stepped in a direction perpendicular to the flow direction of the intake air is formed on the lower surface 19 of the passage approximately at the center in the width direction of the passage, and as shown in FIG. The lower surface of the circumferential passage 21 is set at a lower position than the lower surface of the outer circumferential passage 22 on the outer circumferential side of the stepped portion 20. Further, as shown in FIG. 4, from the curved passage section 12, #2 branch port 14,
The center line 23 of the lower surface of the inner circumference side passage 21 facing the #3 branch port 15 has an upward slope toward the downstream, and the outer circumference from the curved passage section 12 towards the #1 branch port 13 and #4 branch port 16 also has an upward slope toward the downstream. Side passage 2
The center line 24 of the lower surface of the container 2 also has an upward slope toward the downstream. In this case, the ascending slope of the center line 23 on the lower surface of the inner passage 21 is gentler on the upstream side of the branching points 17 and 18 than the ascending slope of the center line 24 on the lower surface of the outer passage 22. It's summery.

機時にはライザ部１１の底面の裏側が排気ガスに
よつて加熱され、液状燃料の気化が促進される。 In the intake manifold configured as described above, when it is cold, part of the fuel sucked from the carburetor mixes with the intake air to form a mixture, and the remaining fuel that is not sufficiently vaporized becomes liquid and flows through the intake manifold. 10 from the riser part 11 to the curved passage parts 12 at both left and right ends, and from the curved passage part 12 to the branch port 1.
Flows to 3, 14, 15, 16. In this case, during warm-up, the back side of the bottom surface of the riser section 11 is heated by the exhaust gas, and vaporization of the liquid fuel is promoted.

合気の流れにつれて流れて液状燃料も各気筒に対
し均一化しようとする。 The mixture flows through the branch ports 13 and 1 in the curved passage section 12.
Although it is bent to the 4, 15, and 16 sides, the curved passage section 1
Since the straight portions 25c of the outer circumferential wall 25 of No. 2 are inclined so as to intersect on the cylinder head side, the flow of fuel in the air-fuel mixture is changed along the wall, and the fuel is distributed uniformly to the outer circumferential side branch ports 13 and 16. This will attempt to equalize the flow of what tends to flow into the inner peripheral side branch ports 14 and 15 in a larger amount than before. As the air-fuel mixture flows, the liquid fuel also tries to be uniform for each cylinder.

岐ポート１５にも多量に流入し、各気筒への液状
燃料の分配が均一化される。 The liquid fuel changes its flow position on the passage lower surface 19 depending on its own weight, but since the curved passage part 12 has a stepped part 20 formed on the passage lower surface 19, the liquid fuel flows on the lower inner peripheral passage 21 side. It is sent. The liquid fuel flowing through the inner circumference side passage 21 passes through the #1 branch port 13,
Even if it tries to flow to the #4 branch port 16 side, it is blocked by the stepped portion 20, so most of it remains as it is at #2.
It flows into the branch port 14 and #3 branch port 15. Furthermore, since the ascending slope of the inner circumferential passage 21 is gentler than the ascending gradient of the outer circumferential passage 22, more liquid fuel flows with less resistance through the passage with a gentle slope, and the liquid fuel flows through the #2 branch port 14 and the #3 branch port. 15 becomes easier to flow into. Therefore, liquid fuel, which conventionally tended to flow into the #1 branch port 13 and #4 branch port 16, also flows into the #2 branch port 14 and #3 branch port 15 in large quantities, resulting in a large amount of liquid fuel flowing into each cylinder. Distribution of liquid fuel is evened out.

混合比もそれだけ均一化されることになる。 On the other hand, the amount of intake air or mixture sucked into each cylinder is determined from the cylinder capacity and is almost constant for each cylinder, but as mentioned above, in the present invention, the distribution of liquid fuel to each cylinder is equalized. , the mixture ratio in each cylinder is also made more uniform.

As described above, when using the intake manifold for an internal combustion engine of the present invention, a stepped portion is provided on the lower surface of the passage from the curved passage section to the branch port to make the lower surface of the curved inner circumferential passage lower than the lower surface of the outer circumferential passage. At the same time, the upward slope of the lower surface of the inner circumferential passage toward the #2 branch port and #3 branch port is set from the upward slope of the lower surface of the outer circumferential side passage toward the #1 branch port and #4 branch port from the branch point of the branch port. Since it is made gentler on the upstream side, it is possible to equalize the distribution of liquid fuel to each cylinder during a cold start.
This prevents smoldering plugs in the #1 and #4 cylinders and misfires in the #2 and #3 cylinders, and improves output performance through uniform fuel distribution. Through this improvement, the effect of ultimately being able to improve fuel efficiency can be obtained.
