Abstract
A secondary air supply system for an internal combustion engine having a supercharger comprises a secondary air supply valve operable in response to the pulsating flow of exhaust gases emitted from at least one of engine cylinders. The remaining engine cylinders are communicated to an exhaust gas purifying device through a supercharger so that the exhaust gases emitted therefrom can drive a turbine of the supercharger. The exhaust gases emitted from such at least one of the engine cylinders are directly supplied to the exhaust gas purifying device in admixture with a secondary air supplied by the valve to facilitate an effective and efficient purification of the exhaust gases as a whole.
