Abstract
PURPOSE:To improve distribution between cylinders and the thermal efficiency of the engine by a method wherein the length of suction pipe is shortened to decrease the resistance of a suction air path as much as possible and the suction air pressure impressed on each ramificated path is made proportional to the length of the suction pipe. CONSTITUTION:The shape of the section of the path of the secondary side assembling section 6 of the suction manifold 2 is formed so as to have a flat shape having a longer axis R1 and a shorter axis Rs while the primary side assembling section 4 of the manifold is arranged in the direction of the shorter axis Rs so as to be approached to the secondary side assembling section 6. The suction air is flowed only through the primary side assembling section 4 in low and middle load zone and the responding property of fuel is good in this case, since the assembling section 4 is provided on the flange 12 at the cylinder head side. In a high load zone, the suction air in the assembling section 6 is collided against the outer wall of the assembling section 4, is detoured around the peripheral wall thereof, is flowed into the mainfolds 6-2 and is balanced with the suction air in the other manifolds, therefore, the distributing property may be improved.
