Low-pressure exhaust gas recirculation valve unit for vehicle, has valve housing and low-pressure exhaust gas recirculation passage, through which exhaust gas recirculation gas flows

摘要

The low-pressure exhaust gas recirculation valve unit (1) has a valve housing (4) and a low-pressure exhaust gas recirculation passage (2), through which an exhaust gas recirculation gas flows. The low-pressure exhaust gas recirculation passage defines an intake passage (3), through which the intake air flows. The valve housing contains a connecting section between the low-pressure exhaust gas recirculation passage and the intake passage.
