In a secondary air delivery device for an internal combustion engine comprising a secondary air charger with a compressor and a turbine which is driven by the vacuum generated in the engine intake duct and which drives the compressor that delivers secondary air to the engine exhaust duct, wherein the engine intake air duct includes an air filter for filtering the air supplied to the engine, a separate air filter structure is provided for filtering the air supplied to the compressor and to the turbine which air filter structure is accommodated in the housing of the secondary air charger.
A secondary air delivery device for an internal combustion engine (10), comprising a secondary air charger (14) with a housing (47) including a compressor (15) and a turbine (16), the turbine (16) being driven via a vacuum prevailing in an intake duct (16) of the internal combustion engine (16), and the turbine in turn driving the compressor (15) which delivers secondary air into the exhaust gas duct (12) of the internal combustion engine (10), said intake duct (16) including an intake air filter (4) for filtering air passing to the internal combustion engine, and an air filter structure (45) provided in the secondary air charger (14) for filtering the air supplied to the compressor (15) and the turbine (16) said air filter structure (45) being accommodated in the housing (47) of the secondary air charger (14).
