Abstract
A control device for an internal combustion engine is applied to an internal combustion engine mounted on vehicles in which filters for collecting PM are arranged in an exhaust passage. After the internal combustion engine is started, the control device of the internal combustion engine executes a temperature raising process of raising the upstream side exhaust temperature, which is the temperature of the exhaust gas on the upstream side of the filter in the exhaust passage, until the condensed water of the filter reaches a vaporized state.
Claims4
A control device for an internal combustion engine mounted in a vehicle including a filter that collects particulate matter (PM) disposed in an exhaust passage, the control device comprising a processor and a memory storing instructions that, in a case executed by the processor, cause the control device to execute temperature raising processing of raising an upstream-side exhaust temperature that is a temperature of exhaust on a side further upstream than the filter in the exhaust passage until a state where condensed water at the filter has been vaporized is achieved after the internal combustion engine is started,
- wherein, in a case where an amount of accumulated PM in the filter is equal to or greater than a threshold value at a time that the internal combustion engine is started, the control device does not execute the temperature raising processing.
