The invention relates to the technical field of vehicle exhaust, in particular to a vehicle exhaust system and an automobile. A vehicle exhaust system includes: an EGP body mounted on a frame cross member; the air inlet side of the exhaust pipeline equipment is communicated with the air outlet of the EGP main body, the air outlet side of the exhaust pipeline equipment extends upwards in the direction perpendicular to the frame cross beam, and the tail end of the air outlet side of the exhaust pipeline equipment is lower than the top surface of the cab rear wall; the two ends of the exhaust pipe support are installed on the EGP body and the side face of the exhaust pipeline device, the two ends of the inclined supporting rod are connected with the frame cross beam and the exhaust pipe support, and the projections of the exhaust pipe support, the inclined supporting rod and the frame cross beam in the Y direction of the vehicle define a triangle. The Bernoulli principle is used for accelerating exhaust of tail gas from exhaust pipeline equipment, and liquid residues in the exhaust pipeline equipment are avoided. The radiating effect of the exhaust pipe is optimized, and high-temperature catalytic reaction is avoided. The connecting structure is arranged triangularly, so that the exhaust tail pipe is more stable, and the damage frequency of an exhaust system is reduced.

    本申请涉及一种车辆排气技术领域,具体涉及一种车辆排气系统及汽车。车辆排气系统,其包括:EGP主体,其安装于车架横梁上;排气管路设备,其进气侧与EGP主体出气口连通,排气管路设备的出气侧朝垂直车架横梁方向向上沿伸,且排气管路设备的出气侧末端高度低于驾驶室后围的顶面;排气管支架,两端安装于EGP主体和排气管路设备侧面,斜支撑杆,其两端与车架横梁和排气管支架相连,排气管支架、斜支撑杆和车架横梁在车辆的Y方向上的投影围成三角形。本申请利用伯努利原理加速尾气从排气管路设备排出,避免了排气管路设备内有液体残留。优化排气管散热效果,避免高温催化反应。本申请连接结构三角布置,使排气尾管更加稳定,减少了排气系统的损坏频率。
