摘要： An engine control system includes a unit which outputs a command for changing an air-fuel ratio of an exhaust gas, a unit which computes an in-cylinder oxygen concentration, a memory which stores a first value and a second value of parameters (ignition timing, injection pressure, pilot injection quantity). The first value is set in a case that the in-cylinder oxygen concentration is a first oxygen concentration. The second value is set in a case that the in-cylinder oxygen concentration is a second oxygen concentration which is higher than the first oxygen concentration. The values of the parameters are set in such a manner as to correlate to the in-cylinder oxygen concentration of during a transition period of the air-fuel ratio. The values of the parameters are obtained by an interpolation based on the first and the second value of the parameter and the in-cylinder oxygen concentration.

摘要： An exhaust gas cleaning apparatus includes a combustion mode shifter that shifts combustion in a cylinder of an engine from a lean-burn mode to a rich-burn mode for enabling a LNT to reduce NOx contained in the exhaust gas. The combustion mode shifter is configured to: estimate a torque-producing fuel quantity for a fuel injection made by a fuel injector when the combustion is in the lean-burn mode; estimate an excess oxygen ratio for an upcoming fuel injection during the shifting of the combustion from the lean-burn mode to the rich-burn mode; estimate a fuel burning percentage for the upcoming fuel injection based on the excess oxygen ratio; set a command injection quantity for the upcoming fuel injection based on the torque-producing fuel quantity and the fuel burning percentage; and control the fuel injector to inject the command injection quantity of fuel into the cylinder in the upcoming fuel injection.
