<p>A combustion control apparatus for an internal combustion engine (1) having an exhaust gas purifier (13, 14) in an exhaust passage (10), includes a controller (5, 11, 9, 20) that controls supply of fuel and air to the engine. The controller (5, 11, 9, 20) is configured to produce preliminary combustion at or near compression top dead center and main combustion after an end of the preliminary combustion under a predetermined condition based on a condition of the exhaust gas purifier. The controller is further configured to determine a target intake air quantity (tQac) by adding an increase correction to the target intake air quantity (tQac) based on a torque correction value (ka) and determine a target fuel injection quantity (tQF) by calculating the target fuel injection quantity (tQF) from an actual air quantity (Qac) and a target air/fuel ratio. A combustion control method is also provided. <IMAGE></p> |
