Example Embodiment
[0028] figure 1 It is a structural schematic diagram of a low-pressure EGR system of a vehicle engine according to an embodiment of the present invention.
[0029] In particular, see figure 1 The present invention provides a low-pressure EGR system for a vehicle engine. The system passes through an engine 5, wherein the engine 5 has an intake port and an exhaust port. The system may include an intake pipe 2, an exhaust pipe 3, an EGR pipe 4 and an electronic supercharger 1. Wherein, the intake pipe 2 is arranged before the intake port, and is used for the inflow of gas from the engine 5. The exhaust pipe 3 is arranged behind the exhaust port and is used for exhaust of the exhaust gas of the engine 5. The EGR pipe 4 is connected between the intake pipe 2 and the exhaust pipe 3, and is used to recirculate part of the exhaust gas discharged from the exhaust pipe 3 into the intake pipe In 2, so that part of the exhaust gas discharged from the engine 5 is reused. The electronic s...
