    摘要： An object of this invention is to provide a control apparatus for an internal combustion engine which makes it possible to reliably avoid an abnormal increase in in-cylinder pressure due to pre-ignition. The control apparatus of this invention controls an internal combustion engine including an injector that directly injects fuel into a cylinder. The control apparatus includes pre-ignition detection means that executes an operation to detect pre-ignition until a time of a crank angle θA, and injection instruction means that, at a time of a crank angle θB that is before the crank angle θA, sends to the injector an injection instruction to perform fuel injection that suppresses pre-ignition combustion. Preferably, the control apparatus includes energization stopping means that, when the pre-ignition detection means does not detect pre-ignition until the time of the crank angle θA, stops energization of the injector that is started by the injection instruction.

    摘要： An inter-cylinder air-fuel-ratio imbalance determination apparatus includes an air-fuel-ratio sensor in an exhaust passage of an engine. The air-fuel-ratio sensor functions as a limiting-current-type wide range air-fuel-ratio sensor when a voltage is applied, and functions as a concentration-cell-type oxygen concentration sensor when no voltage is applied. The determination apparatus causes the air-fuel-ratio sensor to function as the limiting-current-type wide range air-fuel-ratio sensor, and executes air-fuel ratio feedback control on the basis of the output value of the air-fuel-ratio sensor. When an imbalance determination parameter is obtained, the determination apparatus causes the air-fuel-ratio sensor to function as the concentration-cell-type oxygen concentration sensor, and obtains, as the imbalance determination parameter, a value corresponding to the differentiated value of the output value of the air-fuel-ratio sensor. The determination apparatus determines an inter-cylinder air-fuel-ratio imbalance state, when the absolute value of the imbalance determination parameter is greater than an imbalance determination threshold value.

    摘要： A method for operating an internal combustion engine, in particular a gas engine having at least two cylinders, includes acquiring a cylinder-specific first cylinder signal (pmax, E) from each cylinder. At least one combustion parameter (Q, Z) of the corresponding cylinder is controlled as a function of the first cylinder signal (pmax, E), and a cylinder-specific reference cylinder value (pmax′, E′) is set for the first cylinder signal (pmax, E) for each cylinder. The at least one combustion parameter (Q, Z) of the cylinder is adjusted as a function of the deviation of the first cylinder signal (pmax, E) from the reference cylinder value (pmax′, E′), and the first cylinder signal (pmax, E) tracks the reference cylinder value (pmax′, E′).

    摘要： A control device for an internal combustion engine with a catalyst includes: an air-fuel ratio control unit varying a fuel amount supplied to the engine in accordance with a first variation amount set such that an air-fuel ratio of air-fuel mixture coincides with a target ratio; and an exhaust gas temperature control unit varying a fuel amount supplied to the engine in accordance with a second variation amount set to decrease an exhaust gas temperature. When air-fuel ratio control is being executed at a first time point and at least exhaust gas temperature control is executed during a period from the first time point or later to a third time point thereafter, the first and second variation amounts at a fourth time point in the period are set so as to be larger than or equal to the first variation amount at the first time point.
