摘要： A first, a second, and a third combustion region are defined by the air-fuel ratio of the mixture gas feeding combustion. Upon switching of combustion regions from the first combustion region to the third combustion region and from the third combustion region to the first combustion region, namely, when the second combustion region is passed, the mass of NOx emission downstream of an exhaust purifying device and the torque variation are estimated online. Based on the estimated value of the mass of NOx emission and the estimated value of the torque variation, the mass of intake air introduced into the combustion chamber is adjusted in a manner different from when normal, such as by changing the amount of lift of the intake valve, for example, so as to reduce the mass of NOx emission downstream of the exhaust purifying device and the torque variation below predetermined values upon passing of the second combustion region. Thus, the increase in exhaust emissions and the deterioration of operability during the switching of combustion regions can be suppressed.

Variable valve mechanisms vary at least one of the valve timings and valve lifts of an intake valve and an exhaust valve. Intake air is regulated to vary the amount of air intake into a combustion chamber on the upstream side of a combustion chamber inlet of the compression ignition internal combustion engine. The variable valve mechanisms and the intake air regulation are controlled during the compression ignition combustion so as to perform the compression ignition combustion.

摘要： An engine controller capable of reducing torque fluctuation and the like in change between spark ignition combustion and homogeneous charge compression ignition combustion is provided. Spark ignition burning mode or homogeneous charge compression ignition burning mode is selectively set as burning mode according to the operating state of an engine. In spark ignition burning mode, a spark plug is used. In homogeneous charge compression ignition burning mode, fuel is burned utilizing pressure rise in a combustion chamber in conjunction with the ascent of a piston. The burning mode is changed between these modes. In transition for change between the spark ignition burning mode and the homogeneous charge compression ignition burning mode, the following measure is taken: a period during which the lift amount and/or the valve opening period (IVevent) of an intake valve is made smaller than a set value for the homogeneous charge compression ignition burning mode is provided.
