  • Publication number: 20140033687
    Abstract: The present invention has its object to provide a technique which can eliminate HC poisoning of an exhaust gas purification catalyst in a suitable manner in a fuel injection control system of an internal combustion engine which can use a liquid fuel and a gas fuel. In order to achieve this object, the present invention is constructed such that in the fuel injection control system of an internal combustion engine capable of using a liquid fuel and a gas fuel, when HC poisoning of the exhaust gas purification catalyst has occurred, HC poisoning is intended to be eliminated by causing the internal combustion engine to operate by the use of the gas fuel if the temperature of the exhaust gas purification catalyst is less than a specified value, whereas the elimination of HC poisoning is intended by causing the internal combustion engine to operate by the use of the liquid fuel if the temperature of an exhaust gas purification device is not less than the specified value.

  • Publication number: 20130101474
    Abstract: An ambient NOx adsorption catalyst that can adsorb NOx contained in an exhaust gas in the presence of CO under standard conditions is placed in an engine exhaust gas passage, in an internal combustion engine. Until an engine post-initiation catalyst is activated, the amounts of a high-boiling-point hydrocarbon and an unsaturated hydrocarbon that are contained in the exhaust gas flowing into the catalyst are reduced so that the NOx-adsorbing activity cannot be deteriorated by the adhesion activity of the hydrocarbons while maintaining the CO concentration in the exhaust gas flowing into the catalyst at a level higher than the concentration required for the adsorption of NOx.
