Abstract
A V-type multi-cylinder internal combustion engine having a high volumetric efficiency and a high output torque is provided. Ignitions in right and left banks occur alternately and at equal intervals. A suction manifold shaped symmetrically in respect of right and left is disposed between the right and left banks. The suction manifold comprises right and left throttle base, a suction manifold upper formed with right and left suction passages communicating with respective suction ports in the left and right banks and arranged one by one alternately, right and left first chambers formed at contact surface portions between the throttle bases and the suction manifold upper, a suction manifold lower having right and left chambers. The right and left first chambers and the right and left second chambers always communicate with each other, respectively. Right and left second suction passages for connecting the right and left second chambers with the respective suction ports through the right and left first suction passages are formed around the right and left second chambers. The suction manifold is fixed on right and left cylinder heads by attaching the suction manifold upper to the cylinder heads.
