Brennkraftmaschine mit Kompressionszündung und Steuerungsverfahren für eine Brennkraftmaschine mit Kompressionszündung und Kraftstoff-Luftvormischung

摘要

A control apparatus for a premixed compression ignition type internal combustion engine, having a fuel injection valve (4) for supplying a fuel into a combustion chamber (1) of the engine, an operational condition detecting means for detecting the operational condition of the engine, and a fuel injection control means for controlling the fuel injection valve (4) on the basis of the results of the detection carried out by the operational condition detecting means, the fuel injection control means controlling the fuel injection valve so that the supplying of a fuel to the combustion chamber is finished at least before a piston (2) reaches a compression top dead center, the control apparatus including an air supply means for supplying pressurized air to the combustion chamber (1), and an air quantity control means for controlling the air supply means, the air quantity control means controlling a supply rate of the pressurized air so that the combustion of a gaseous mixture by self-ignition is carried out by a compression effect of the piston (2) of the engine when the piston (2) is in the vicinity of a compression top dead center. This control apparatus secures an output corresponding to the time of a high-loaded operation of the engine as the reduction of NOx is effected.
