Claims

[Scope of utility model registration request]

Throttle valves are independently pivoted to the intake manifolds provided for each cylinder of the engine, and gas recirculation ports are arranged near these throttle valves to recirculate exhaust gas and other gases to the engine. In the gas recirculation passage, which is provided and opened, and through which gas such as exhaust gas is recirculated from the gas recirculation port to the intake manifold, the gas recirculation passage is integrally disposed in the collecting member, and the gas recirculation passage is 1. A gas recirculation device for an independent intake engine, characterized in that discharge ends are collected and the collective discharge ends are communicated with a single gas recirculation port provided for each intake manifold.
