Abstract
Based on an exhaust gas temperature on an upstream side acquired by an upstream temperature acquisition device, in performing control of supplying an unburned fuel to an oxidation catalyst device in a case where the exhaust gas temperature on the upstream side is lower than a low temperature, a control device performs control of adjusting at least one of an injection timing of a cylinder injection valve and opening-closing timing of an exhaust valve at least one of before and after the supplying control; raising a temperature of the exhaust gas that substantially free of unburned fuel discharged from the exhaust valve to be higher than the low temperature; and warming the oxidation catalyst device until a predetermined warming period has passed.
