Claims

[Scope of utility model registration request]

(1) A chamber provided between the intake pipe and the intake port to reduce the pressure of the inertial intake air, attenuate the intake pulsation, and regulate inertial intake interference, and on the intake port side of the chamber,
A divided decompression chamber formed by dividing the intake ports of cylinders that are adjacent in the ignition order to isolate them; and a common decompression chamber formed in continuity with each of the divided decompression chambers on the intake pipe side of the chamber. An inertial intake interference prevention device for a multi-cylinder engine, characterized by comprising:

(2) The inertial intake air interference prevention device for a multi-cylinder engine according to claim 1, wherein the divided pressure reduction chamber and the common pressure reduction chamber are respectively partitioned by a partition plate within the chamber.

(3) Prevention of inertial intake interference in the multi-cylinder engine according to claims 1 and 2 of the utility model registration claim, wherein the divided decompression chamber includes the intake ports of cylinders that do not adjoin each other in the ignition order in the same room. Device.
