摘要： An ignition timing control system is provided for an in-cylinder injection internal combustion engine to reduce a torque shock upon switching a fuel injection mode between a compression-stroke injection mode, in which an injection of fuel is performed primarily in a compression stroke, and an intake-stroke injection mode, in which an injection of fuel is performed primarily in an intake stroke, in accordance with an operation state of said internal combustion engine. The ignition timing control system is provided with an injection timing correction unit for correcting ignition timing of a spark plug, which is arranged in a combustion chamber, upon switching said fuel injection mode. A correction amount for ignition timing, by which said ignition timing is corrected by said ignition timing correction unit upon switching from said compression-stroke injection mode to said intake-stroke injection mode, is greater than a correction amount for ignition timing, by which said ignition timing is corrected upon switching from said intake-stroke injection mode to said compression-stroke injection mode.

摘要： In an intra-cylinder injection type engine, a first fuel cut-off starting rotational speed, a first return rotational speed and a first target idling speed in a compression stroke injection mode, which is superior in both combustion and responsivity, are set at lower speeds than a second fuel cut-off starting rotational speed, a second return rotational speed, and a second target idling speed in a suction stroke injection mode. During an operation in the compression stroke injection mode, a fuel cut-off mode and an idle running of the engine are practiced at a low engine speed, to improve the fuel economy without causing deterioration of combustion.

摘要： In a combustion control device for an internal combustion engine provided with a plurality of fuel injection modes having different target air-fuel ratios, threshold values for detecting deterioration of combustion in the internal combustion engine are determined separately for each fuel injection mode depending on features of variation of combustion in the internal combustion engine in each fuel injection mode. Quantity of variation of combustion in the internal combustion engine is, for example, detected in the form of revolution angular acceleration or revolution angular acceleration deviation of the engine. The detected quantity of revolution fluctuation is compared with a threshold value in the currently chosen fuel injection mode. Thus, deterioration of combustion is surely judged according to each fuel injection mode. In particular, threshold values in a compression stroke injection mode are determined to be larger than threshold values in an intake stroke injection mode. A threshold value in the compression stroke injection mode is so determined as to substantively correspond to a complete misfire state of the engine, and threshold values in the intake stroke injection mode consist of a first threshold value substantively corresponding to a complete misfire state of the engine and a second threshold value substantively corresponding to an unstable combustion state of the engine.
