Abstract
An exhaust pipe, a method for optimizing and designing an exhaust pipe, and an engine are provided. The exhaust pipe includes a first exhaust pipeline arranged in a first direction, an EGR pipeline arranged in a second direction, and a pre-turbine pipeline arranged in a third direction. An input end of the EGR pipeline is communicated with an output end of the first exhaust pipeline, and an included angle θ.sub.1 between the first direction and the second direction is smaller than 60°. The pre-turbine pipeline, the EGR pipeline and the first exhaust pipeline are located in a first plane; the pre-turbine pipeline is communicated with the EGR pipeline, an included angle θ.sub.2 between the third direction and the second direction is smaller than or equal to 90°, and a cross-sectional diameter D of the pre-turbine pipeline is 0.2-1 times the diameter of the first exhaust pipeline.
