EXHAUST PIPE INJECTION CONTROL DEVICE

Provided is an exhaust pipe injection control device capable of controlling an appropriate fuel injection amount regardless of engine rotation speed. The exhaust pipe injection control device includes: a target injection amount setting unit 172 which sets, according to an engine rotation speed and an exhaust gas flow rate, a target injection amount that is injected in a single injection from an exhaust pipe injector 141; a BPW map 173 in which a fuel injection time of the exhaust pipe injector 141 is set so that, with respect to the target injection amount and an exhaust pipe injection fuel pressure, fuel in the target injection amount is injected; and an exhaust pipe injection executing unit 174 which performs injection from the exhaust pipe injector 141 by referring to the BPW map 173 based on the target injection amount and the exhaust pipe injection fuel pressure.
