摘要： An EGR apparatus includes a EGR passage for allowing part of exhaust gas discharged from a combustion chamber of an engine to an exhaust passage to flow in an intake passage and recirculate back to the combustion chamber, and an EGR valve provided in the EGR passage to regulate an EGR passage in this passage. The EGR valve includes a valve seat, a valve element to be seatable on the valve seat, and a step motor for driving the valve element to open and close. An electronic control device controls the EGR valve to repeat opening and closing of the valve element between a closing position and a small opening position in order to remove foreign matters adhered to the valve seat or valve element during deceleration fuel cutoff of the engine.

摘要： The present invention is intended to detect insulation failure of an EHC. In the invention, a heat generation element of the EHC is electrically insulated by an insulating member. Then, a determination as to whether insulation failure has occurred is made based on an insulation resistance value of the insulating member at the time when an amount of water absorption in the insulating member is smaller than a predetermined amount of water absorption and when an amount of PM deposition in the insulating member is smaller than a predetermined amount of PM deposition, a change in the insulation resistance value of the insulating member at the time when the amount of water absorption in the insulating member decreases from an amount equal to or larger than the predetermined amount of water absorption to an amount smaller than the predetermined amount of water absorption, and a change in the insulation resistance value of the insulating member at the time when the amount of PM deposition in the insulating member decreases from an amount equal to or larger than the predetermined amount of PM deposition to an amount smaller than the predetermined amount of PM deposition.

摘要： The fuel injection apparatus for the internal combustion engine includes: a fuel injector having a leading end portion that has an internal space in which fuel is accumulated and an injection port for injecting fuel; and an adsorbent disposed in the internal space, the adsorbent being capable of selectively adsorbing an alcohol component in a blended fuel of gasoline and alcohol. In this fuel injection apparatus, it is determined whether or not a fuel pressure is higher than a predetermined low fuel pressure when a request is issued for bringing an internal combustion engine to a stop. If it is determined that the fuel pressure is higher than the low fuel pressure, the fuel pressure is kept at the low fuel pressure for a predetermined period of time before the internal combustion engine is brought to a stop.
