Abstract

[Problem] To provide a control method of an aftertreatment system in which exhaust gas purification performance is less likely to deteriorate, a control program, an aftertreatment system, and an engine system. [Solution] A control method of an aftertreatment system 5 is a control method of the aftertreatment system 5 including a first SCR device 51, a second SCR device 52, a first reducing agent supply device 56, and a second reducing agent supply device 57. The first SCR device 51 is located on the exhaust path 28 through which the exhaust gas discharged from the engine main body 2 passes. The second SCR device 52 is located on the exhaust path 28 and on the downstream side of the first SCR device 51 in a flow direction of the exhaust gas. The first reducing agent supply device 56 supplies the reducing agent to the first SCR device 51. The second reducing agent supply device 57 supplies the reducing agent to the second SCR device 52. The control method of the aftertreatment system 5 includes individually controlling the supply amount of the reducing agent of each of the first reducing agent supply device 56 and the second reducing agent supply device 57.
