| description | The invention provides a method and device for determining a fuel injection amount of a DOC. The method comprises the following steps that an input end actual temperature value, an output end actual temperature value and a total fuel injection amount of the DOC at the current moment are acquired; based on the input end actual temperature value and the total fuel injection amount, a current output end estimated temperature value of the DOC is obtained; based on an output end actual temperature value and a preset output end temperature value, a first fuel injection amount is obtained, and based on the output end estimated temperature value and the set output end temperature value, a second fuel injection amount is obtained through calculation; and according to the first fuel injection amount and the second fuel injection amount, a to-be-injected fuel amount of the DOC at the next moment of the current moment is determined. By means of the method for determining the fuel injection amount of the DOC, the fuel inj |
