Embodiment Construction

[0026] Embodiments of the present invention will be described below based on the drawings.

[0027] refer to Figure 1 to Figure 9 , the configuration of the air intake device 100 according to one embodiment of the present invention will be described. It should be noted that, below, when the engine 110 is used as a reference, it is assumed that each cylinder is arranged along the X-axis direction. In addition, it will be described as follows: when the air intake device 100 is viewed from the engine 110, the side in the direction of arrow X1 is referred to as "left", and the side in the direction of arrow X2 is referred to as "right". Z-axis direction. In addition, the engine 110 is an example of the "in-line multi-cylinder engine" of this invention. In addition, the X-axis direction is an example of the "left-right direction" of this invention.

[0028] Such as figure 1 As shown, an air intake device 100 according to an embodiment of the present invention is mounted on an i...

Abstract

Provided is an intake device mounted to an in-line multi-cylinder engine, the intake device comprising: a surge tank that includes a throttle body attachment section in the center section thereof; one intake pipe and another intake pipe respectively connected to one end section and another end section of the surge tank in the left-right direction; a first intake pipe group connected to the one intake pipe and formed from a branched plurality of intake pipes; and a second intake pipe group attached to the other intake pipe and formed from the same number of branched intake pipes.

Description

technical field [0001] The invention relates to an air intake device, in particular to an air intake device mounted on an in-line multi-cylinder engine. Background technique [0002] Conventionally, there is known an air intake device mounted on an in-line multi-cylinder engine. Such an intake device is disclosed in, for example, Japanese Patent Application Laid-Open No. 7-253062. [0003] Japanese Patent Application Laid-Open No. 7-253062 discloses an intake manifold (intake device) for an inline four-cylinder engine. The intake manifold described in Japanese Patent Application Laid-Open No. 7-253062 includes a surge tank having a substantially isosceles triangle (mountain-shaped) cross-section and four intake pipes connected to the surge tank. It should be noted that a throttle valve body installation seat (throttle valve body installation part) is provided on the upper surface of the buffer tank. Two intake pipes are respectively connected to the right side and the lef...
