ンジンルーム内に収納するのが困難となる。(Prior art) In order to increase engine output, it is effective to improve intake air filling efficiency, but in recent years,
Attempts have been made to utilize the dynamic effect of intake air to improve this filling efficiency. The dynamic effects of this intake include a pulsation effect that utilizes the pulsation of the intake air in the intake passage, an inertia effect that uses the kinetic energy of the intake air, and a resonance effect that uses the resonance of vibrations of the intake air within the intake system. However, when utilizing the resonance effect in a V-type engine, there was a problem in how to configure the intake system.
In other words, in order to utilize the resonance effect, in order to avoid interference of intake vibration between cylinders, the intake system must be separated into banks each consisting of cylinders in which the intake order is not consecutive, and a resonance chamber must be installed in each intake system. It is necessary to provide an enlarged chamber that acts as a resonance pipe, and a passage of a required length connected to the upstream side of the enlarged chamber that acts as a resonance pipe, which increases the bulk of the intake system and increases the overall engine size. Due to their large size, it is difficult to store them in the limited space of the engine room, especially in the case of automobile engines.

There is an idea disclosed in Publication No. 56328. this is,
By inserting the upstream portions of the intake passages that are independently connected to each cylinder on the downstream side of the enlarged chamber (intake silencer in the above publication) into the enlarged chamber, the required length of intake air can be achieved with a compact configuration. This is an attempt to secure a passage. However, this method attempts to utilize the inertial effect of intake air on the downstream side of the expansion chamber, and this method attempts to utilize the resonance effect of intake air by securing an intake passage of a required length on the upstream side of the expansion chamber. The purpose is different from an idea.

Utilizing the layout of the expansion chambers provided at the center of both banks of a V-type engine, it is possible to provide an intake passage with sufficient length on the upstream side of the expansion chambers without increasing the size of the entire intake system. The purpose of this is to realize a V-type engine that is compact and has excellent output performance.

The enlarged chamber is divided into a first chamber and a second chamber, and a plurality of independent intake passages from both banks are connected to both side walls of the enlarged chamber facing the partition wall, and an intake passage is provided on the upstream side of the enlarged chamber. is branched into two passages acting as resonance pipes, and both branch passages are connected to the first chamber and the second chamber, respectively. and,

Furthermore, by arranging the expansion chamber at the center of the two banks and by extending the branch passage as a resonance pipe on the upstream side of the expansion chamber into the expansion chamber, the intake device can be prevented from increasing in size. A resonance tube of sufficient length is ensured and the resonance effect is improved. In particular, since the extension of the branch passage is formed by a partition wall within the expansion chamber and a passage wall provided along the partition wall, the interior of the expansion chamber becomes extremely complicated, and the widthwise dimension of the expansion chamber increases. Furthermore, since the independent intake passage is connected to both side walls of the enlarged chamber facing the partition wall or passage wall, there is a sufficient space between the resonance pipe and the opening of the independent intake passage in the enlarged chamber. By ensuring a suitable spacing, an increase in intake resistance is avoided, and the flow to the independent intake passage is prevented from interfering with resonance waves in the resonance pipe.
