摘要： A method and system for starting an internal combustion engine by utilizing combustion energy produced by injecting and igniting fuel in an engine cylinder under the expansion stroke, which can eliminate the necessity of precisely computing the combustion energy, can minimize an amount of energy, other than the combustion energy, supplied from a second energy supply unit, and can realize stable engine startup without causing a startup failure due to a combustion failure. At startup of the engine, energy is supplied to the engine from both a first energy supply unit performing direct injection and ignition of fuel, etc. and a second energy supply unit employing, e.g., a starter motor, thereby starting the engine. After the engine has started motion, the motion status of the engine is determined based on, e.g., the engine revolution speed, and the energy supply to the engine from the second energy supply unit is stopped based on a determination result.

摘要： Provided is a control device for an engine which is capable of purifying NOx with high efficiency at a restart after an idle stop without deteriorating purification efficiency of HC and CO. At the restart after the idle stop, an air-fuel ratio is controlled to be rich, and an atmosphere inside of a catalyst is estimated on the basis of a required time ΔT from a time point at which an output value (VO2—2) of first oxygen concentration detection means upstream of the catalyst exceeds a predetermined value A1 to a time point at which an output value (VO2—2) of second oxygen concentration detection means downstream of the catalyst exceeds a predetermined value A2, whereby an air-fuel ratio at next and subsequent restarts is corrected so that the atmosphere inside of the catalyst is optimized at the next and subsequent restarts.

摘要： The present invention performs correction appropriately according to errors in the fuel system and air system respectively and corrects both variations in the air-fuel ratio and torque. When the difference between a target air-fuel ratio and a real air-fuel ratio is equal to or below a predetermined value when feedback control based on the air-fuel ratio of an exhaust manifold 10A is in progress, the air-fuel ratio of a cylinder cyl—1 having the largest variation of angular acceleration is corrected to the rich side, for example, by increasing the amount of fuel. Angular acceleration per cylinder is then detected again and when the variation in angular acceleration among cylinders is not eliminated, it is judged that there is an error in the amount of air control of the cylinder having the largest variation and the amount of air, amount of fuel, ignition timing or the like are corrected.

摘要： An engine controller capable of optimizing both the air-fuel ratio and the ignition timing to provide HC-minimized performance under the relevant driving conditions (environmental conditions) in order to minimize the amount of HC emitted from an engine at the time of start-up (before catalyst activation) is provided. The engine controller includes: air-fuel ratio control means for controlling the air-fuel ratio to be within a predetermined range (for example, 14.5 to 16.5) when the engine is operated at a certain driving condition (for example, in a state in which the catalyst is not activated such as the time of starting a cooler, or idling time); and ignition timing correction means for correcting the ignition timing to the retard side when the engine is operated at the certain driving condition and the air-fuel ratio is within the predetermined range.
