Claims

[Scope of utility model registration request]

a filter that is attached to an exhaust path of an internal combustion engine and that captures exhaust particulates; an incineration unit that incinerates the exhaust particulates captured by the filter; an accumulation amount information generating unit that outputs information on the amount of accumulated exhaust particulates; an exhaust temperature information generating means for outputting information on the exhaust gas temperature of the road; a deposition amount setting means for setting the amount of exhaust particulates deposited when the incineration means is started; Exhaust temperature setting means to be set, when the current amount of exhaust particulate accumulation exceeds the set amount of deposition, and when the current exhaust temperature exceeds the set exhaust temperature,
An exhaust gas after-treatment device comprising: an incineration command generating means for issuing an incineration command to the incineration means.
