接続するように構成している。(Prior art) In an engine intake system, in order to provide good intake air to each cylinder, filling is performed by effectively utilizing the intake ln effect by synchronizing the pulsation of the intake passage and the number of intake operations of the cylinder. For example, as a way to improve efficiency,
There is one shown in Publication No. 8-34401. A surge tank (air chamber) is installed in the intake passage, and intake air is supplied to each cylinder through an independent passage through this surge tank.
In addition, in order to eliminate the inhibition of the intake inertia effect due to intake air interference between cylinders, the surge tank installed in the middle of the intake passage was divided into two, and cylinders with non-consecutive ignition orders were connected to each divided chamber. It is composed of

上の制約の多いＶ型エンジンにおいては、！！！ｉ置が
大型化しないような構成を採用する必要がある。In addition, the engine intake passage is branched into a primary intake passage and a secondary intake passage, and when the amount of intake air is small in the low zero load range, intake air is supplied only from the secondary intake passage, thereby increasing the flow velocity and improving combustibility. An intake system for an engine is known that is designed to improve output by supplying intake air from secondary intake air when the amount of intake air is large. In order to apply this device to a V-type engine and improve the intake inertia effect by installing the surge tank described above, the two intake boats have different characteristics to reduce torque drop at both low speed and high speed. It is desirable to prevent crowding. This objective is achieved by making one length of the intake pipe longer and the other shorter, but in this case, in a V-type engine where there are many restrictions on placement,! ! ! It is necessary to adopt a configuration that does not increase the size of the i-location.

的とするものである。Furthermore, in order to flatten the groove structure and shape of a V-type engine, Japanese Patent Publication No. 51-42272 proposes arranging the intake manifold in a V-shape.
This is intended to supply combustion air to the cylinders and to avoid contamination of the intake manifold and the intake pipe system branching from it.

A first surge tank 7 is arranged in the space between the left and right cylinder rows, and the first surge tank 7 is arranged in the space between the left and right cylinder rows.
A second surge tank 8 is arranged on both sides of the first surge tank 7, and a second intake passage 81 is connected to the second surge tank 8. Therefore, the first intake passage 70
is formed short, and the second intake passage 81 is formed long,
The length of the second intake passage 81 is set to such a length that the intake pulsation and the number of intake operations are synchronized to produce an intake inertia effect. The upstream intake passage 9 branches into a third intake passage 71 and a fourth intake passage 82, the third intake passage 71 is connected to the first surge tank 7, and the fourth intake passage 82 is connected to the second
is connected to the surge tank 8. A pair of blocks showing the dividing line No. 91 and containing the second surge tank 8;
The intake system is divided into a block containing the first surge tank 7 and a block containing the third intake passage 71, thereby facilitating assembly and disassembly.

便利である。In the above configuration, since the first surge tank 7 is arranged in the space between the left and right cylinder rows, the space is effectively utilized and the entire device is configured compactly.
Moreover, it is convenient to make one side of the intake passage short and the other long.

気の充填効率が高められる。In this configuration, the second intake boat 5 is closed during low load, and intake air is supplied from the first surge tank 7 to the combustion chamber 6 through the first intake passage 70 and the first intake boats 1-4. . Since this passage is formed short, the intake resistance is small, and therefore the flow velocity of the intake air is high, and swirl is effectively generated within the combustion chamber to promote combustion. On the other hand, when the load is high, the second intake boat 5 is also supplied with intake air from the second surge tank 8 through the second intake passage 81 and the second intake boat 5, and sufficient intake air is supplied to the combustion chamber 6. is supplied. Moreover, the second intake passage 8
1 is formed long, the intake air filling efficiency is increased due to the intake inertia effect.

In this case, the intake inertia is reduced at low load. This effect improves the intake air filling efficiency and provides well-balanced torque characteristics as a whole.
