載上好ましくない、というような問題を生じる。(Prior art) In a V-type engine in which one cylinder group and another cylinder group are arranged in a V-shape, an intake expansion chamber is defined in the space formed between the two cylinder groups, that is, the central space of the V bank. There is a system in which a surge tank is provided and the surge tank and each cylinder are individually connected to each other through independent intake passages including independent intake pipes (see Japanese Patent Laid-Open No. 101055/1983). The above-mentioned independent intake pipe is generally arranged so as to pass below the surge tank, but if you try to supply fuel from the fuel injection valve near the connection between this independent intake pipe and the cylinder group, the cylinder arrangement of the cylinder group The fuel distributor that extends in the direction and distributes and supplies fuel to this fuel injector is inevitably located considerably above, and therefore, the surge tank is required to have a predetermined capacity in conjunction with this fuel distributor. If an attempt is made to avoid interference with the surge tank, the position of the surge tank becomes quite high, which increases the overall height of the engine, which causes problems such as being undesirable for mounting on a vehicle.

A protrusion formed on the surge tank is positioned between the two fuel distributors. In other words, by providing a fuel distributor for each cylinder group, a relatively large space is formed between the two fuel distributors, so a part of the surge tank, that is, the protruding portion mentioned above, is placed in this large space. By locating the surge tank, sufficient capacity can be secured as a whole by the capacity of the protrusion without increasing the height of the surge tank.
