    摘要： An engine (1) operates in a stratified charge combustion mode and a homogeneous charge combustion mode. A sensor detects driving state of the engine. An ECU (electronic control unit) (30) computes a basic amount of the fuel to be injected from a nozzle (11) based on the detected driving state of the engine. The ECU switches the combustion mode based on the computed basic amount. The ECU computes a corrected amount of the injection fuel based on the basic amount of the injection fuel. The corrected amount of the injection fuel suppresses a fluctuation of engine torque caused by switching of the combustion mode. The ECU controls the injection valve based on the computed corrected amount.

    摘要： A fuel injection control system for a cylinder injection/spark ignition internal combustion engine (1) in which fuel is injected directly into cylinders through fuel injection valves (2). An ECU (6) determines a desired fuel injection amount (Qm) based upon the engine speed (Ne) and engine load (θACC), determines a desired fuel pressure (PFM) to be supplied to the fuel injection valves (2) and controls the actual fuel supply pressure (PF) to the desired fuel pressure (PFM). The ECU (6) causes the fuel to be injected when the crank angle of the engine (1) falls within a predetermined range (20 BTDC to 5 ° ATDC) in the vicinity of a top dead point (TDC) of the cylinder corresponding to the compression stroke thereof. Cylinder pressure is determined by sensor a (3), and the ECU (6) determines the actual amount of fuel (QSAMP) injected over time intervals substantially shorter than the injection period corresponding to the full desired fuel amount (QM), based on the difference between the injected fuel pressure and the cylinder pressure. This value is then subtracted from the desired fuel amount (QM) to control the termination of the fuel injection.
