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.

An in-vehicle temperature estimation device is applied to an in-vehicle heated object heated by current flow. The in-vehicle temperature estimation device includes a power detection unit for detecting the supplied power supplied to the heated object, an arithmetic unit that performs a computation to estimate the temperature of a first location in the heated object, and a temperature determination unit that determines the temperature of the external air outside the heated object. The arithmetic unit performs a computation to estimate the temperature at the first location based on the supplied power detected by the power detection unit and the temperature of the external air determined by the temperature determination unit.

A catalytic converter includes at least one heating element that is configured to disrupt the direction of flow of exhaust gases which contain harmful toxic gases and pollutants and aid in removing and/or reducing said toxic gases and pollutants.
