Zusammenfassung:A mechanical vacuum pump for an engine includes a flange configured for attachment to a cylinder head of the engine. The flange defines a bore, which is configured for interconnecting an injection air inlet in the cylinder head with an injection air outlet of a secondary air injection valve. The secondary air injection valve is directly mounted to the mechanical vacuum pump, thereby indirectly mounting the secondary air injection valve to the cylinder head of the engine, with the bore communicating fresh air from the secondary air injection valve to the cylinder head.
