Definitions
- AI exhaust gas recirculation systems for internal combustion engines have become known, with an exhaust gas recirculation line with venturi opening into the intake system for partial recirculation of the exhaust gas from an exhaust system into an intake system.
- the venturi device can be bypassed via a main air line, the flow of which can be predetermined via a control element.
- the Venturi device is designed to be multi-flow and at least two to form nozzle diffuser units connected in parallel.
- the multi-flow venturi device is arranged together with the main air duct and control element in a common housing.
