  • Patent number: 9587597
    Abstract: In the present invention, an internal combustion engine is provided with an in-cylinder fuel injection valve and a secondary air supply device and is formed so as to make possible first catalyst warming control and second catalyst warming control that promote the raising of the temperature of an exhaust gas purification catalyst. The first catalyst warming control comprises control to inject fuel from the in-cylinder fuel injection valve during the compression stroke to form a stratified state, and control to greatly delay ignition timing. The second catalyst warming control comprises control to supply secondary air to an engine exhaust gas passage. The internal combustion engine executes the first catalyst warming control after startup and, after the first catalyst warming control is executed, carries out control (third catalyst warming control) to execute the first catalyst warming control and the second catalyst warming control simultaneously.

  • Patent number: 9567891
    Abstract: A method is disclosed for controlling a concentration of oxygen that is measured by an oxygen sensor of an after-treatment system of an internal combustion engine when a regeneration of an after-treatment device is required. The method may be a computer-implement method. An oxygen sensor target value is lowered in a stepped phase as a function of an exhaust gas flow speed as the exhaust gas passes through the after-treatment system. The oxygen sensor target value is lowered evenly as a function of the exhaust gas flow speed and by a filter phase when a measured air/fuel ratio value is less than or equal to an AFR threshold value and until the oxygen sensor target value is equal to an oxygen sensor final target value. The oxygen concentration is controlled by applying the oxygen sensor target value.

  • Patent number: 9567889
    Abstract: In an internal combustion engine, an exhaust purification catalyst and a hydrocarbon feed valve are arranged in an exhaust passage. When the air-fuel ratio of the exhaust gas which flows into the exhaust purification catalyst should be made rich, rich control, which makes the air-fuel ratio of the exhaust gas which is exhausted from the combustion chamber rich, is performed. In order to prevent clogging of the hydrocarbon feed valve, clogging preventing injection which injects hydrocarbons from the hydrocarbon feed valve by an injection interval ?tCB is performed. The exhaust purification catalyst has an oxygen storage ability. At the initial period of rich control, clogging preventing injection is performed by a shorter injection interval ?tCS.
