Summary:The invention discloses a method and a device for calculating the EGR rate of an outlet of an air guide pipe. The method comprises the following steps of segmenting the air guide pipe according to thelength of the air guide pipe so as to obtain continuous at least two sections of air guide segmented pipes; obtaining the outlet EGR rate corresponding to each segmented air guide segmented pipe of the last cycle and the initial EGR rate in a current cycle mixing cavity; taking the initial EGR rate as the inlet EGR rate for the current cycle of the first air guide segmented pipe, taking the outlet EGR rate of the former segment of the current cycle as the inlet EGR rate for the current cycle of the adjacent last segment, and connecting an inlet of the first air guide segmented pipe with an outlet of a mixing cavity; calculating the current cycle outlet EGR rate for each segment of the air guide segmented pipes according to the inlet EGR rate of the current cycle corresponding to the air guide segmented pipes and
