Abstract
In an air intake system of a multi-cylinder internal combustion engine with exhaust gas recirculation, particularly a Diesel engine, including an intake duct with a throttle valve wherein the intake duct is connected to an intake manifold of the engine and an exhaust gas recirculation conduit is connected to the intake duct downstream of the throttle valve, the throttle valve includes a valve member provided with a turbulence plate which has a diameter smaller than the valve member and extends normal to the valve member, and the valve member has passages and the turbulence member has holes for generating turbulence in the intake duct downstream of the throttle valve.
