Claims

[Scope of utility model registration request]

A multi-cylinder engine in which the cylinders of a multi-cylinder engine are divided into first and second cylinder groups each including a plurality of cylinders that are ignited at equal intervals, and each cylinder group is provided with a first and second intake manifold, respectively. In the engine, the front end is connected to the air cleaner, the interior is partitioned into left and right first and second intake pipes by a longitudinal partition, and the rear end of each intake pipe is connected to the first and second intake pipes, respectively.
an inertial supercharging air pipe connected to the inlet end of the air supply manifold; a cancel valve for opening and closing openings formed near the rear end and the front end of the longitudinal bulkhead; and a first partition valve; A second partition valve that opens and closes an opening drilled in the vertical partition wall at an intermediate position between the two valves, and a second partition valve that is disposed in each of the inertial supercharging air pipes and loosely surrounds the first and second partition valves, respectively. A multi-point synchronized inertial supercharging system for an engine, characterized by comprising first and second phase inversion chambers.
