摘要： A suction apparatus of a multi-cylinder internal combustion engine has a suction manifold disposed in a direction parallel with a row of cylinders at one side of a cylinder head. The suction apparatus includes a plurality of independent suction passages of equal length each extending from an engine main body at right angle, a suction gathering chamber connected to the suction passages and disposed in the direction parallel with the row of cylinders, a throttle body provided at an upper stream end of the suction gathering chamber, and a resonance vessel communicating with the suction gathering chamber. The resonance vessel is supported by a cylinder head cover and a wall of the gathering chamber elastically through rubber members covering above of the independent suction passages with a space, and communicates with an upper part of the suction gathering chamber at a just downstream position of the throttle body. The space has a volume capable of receiving at least fuel injection valves and fuel supply pipes for respective cylinders of the internal combustion engine.

摘要： An intake system in a multi-cylinder type internal combustion engine comprises throttle valves disposed in a plurality of intake passages commonly connected to an air cleaner, and fuel injection valves disposed in the intake passages downstream of the throttle valves in an intake direction. In such intake system, a plurality of funnel-shaped portions are provided in a throttle body having opposite ends directly coupled to an intake manifold and an air cleaner, respectively, and each of the throttle valves is disposed in the throttle body, so that its upstream end in the intake direction is located at least on the corresponding funnel-shaped portion, when the throttle valve is fully opened. The throttle body includes ports provided therein, which are opened into the intake passages between a coupled surface of the throttle body to the intake manifold and the throttle valves, respectively, and which communicate with one another. This provides an increase in space efficiency and an increase in intake inertial effect.
