Abstract:
A 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, said intake duct being connected to an intake manifold having intake duct sections leading to the various cylinders of said multicylinder internal combustion engine, an exhaust gas recirculation conduit connected to said intake duct downstream of said throttle valve for supplying exhaust gas to said intake duct, said throttle valve including a valve member pivotally supported in said intake duct and a turbulence plate of a diameter smaller than that of said valve member disposed on said valve member so as to extend normally to said valve member and essentially through its pivot axis, said valve member having passages and said turbulence plate having holes for generating turbulence in said intake duct downstream of said throttle valve.
