摘要： An ignition timing control apparatus for an internal combustion engine capable of using as a fuel a regular (low-octane) gasoline, a premium (high-octane) gasoline, or a mixture of both type of gasolines. The engine produces knocks when the ignition timing is advanced beyond a reference ignition timing determined as a function of the type of gasoline being used. This ignition timing control apparatus detects the knocks, and provides as an output therefrom a signal according to the occurrence rate of the knocks which essentially indicates the type of gasoline in use. By means of this signal, this ignition timing control apparatus continuously displaces the reference ignition timing in the direction of retard angle by using a proportion factor calculator and an interpolator. At the same time, the displaced reference ignition timing is corrected by the detected knock signals on a real time basis. The combined ignition timing signal serves to energize an ignition coil to suppress the occurrence of knocks. This operation will continue until no knocks occur. Particularly, when the engine is outside of a predetermined operation region or condition, the displacement magnitude for the reference ignition timing is retained at a value of a normal operating state irrespective of whether or not knocks are detected.

摘要： An engine control unit of a control apparatus for an in-cylinder injection internal combustion engine sets a fuel injection timing for a compression-stroke injection mode in accordance with a fuel injection quantity, and corrects the fuel injection timing according to an engine cooling water temperature. When the cooling water temperature is lower than a temperature observed when a warm-up operation is completed, the fuel injection timing for the compression-stroke injection mode is corrected for advance or retard on the basis of the engine characteristic proper, and fuel is injected at an appropriate time such that the fuel evaporation rate and the fuel stratification degree which permit the stabilized combustion of the fuel injected into the combustion chamber are attained, whereby the fuel is evaporated satisfactorily. Thus, the occurrence of misfire and the emission of harmful gas components can be restrained effectively during the warm-up operation in the compression-stroke injection mode.

摘要： Disclosed is an automobile engine which has different ranges for the partial cylinder operation mode depending upon whether or not the engine is idling. The partial cylinder operation mode is selectable in different operation ranges in response to operating status of an air-conditioner, a power steering switch or a throttle opening sensor. Thus, the engine can reliably assume the partial cylinder operation mode in a wide operation range without stall, thereby accomplishing fuel saving.

摘要： In a fuel blending ratio detecting method, a first blending ratio of the methanol in the fuel supplied to an internal combustion engine is detected by a blending ratio sensor; an air/fuel ratio feedback compensation coefficient computed on the basis of an output of an O.sub.2 sensor is used to compute a feedback learned value, and the current blending ratio compensation coefficient is multiplied by this value to compute the next blending ratio compensation coefficient so as to obtain a second blending ratio; the current blending ratio compensation coefficient is multiplied by a peak mean value of the computed feedback compensation coefficient to compute the next blending ratio compensation coefficient so as to obtain a third blending ratio; and the first, second or third blending ratio is selected according to the operating conditions of the internal combustion engine. Thus, the selected blending ratio is always used as the control blending ratio very close to the true ratio, so that the internal combustion engine can be accurately controlled.

摘要： The method of the invention uses a molding slurry containing a particulate oxide magnetic material and water and having a dispersant added thereto. The dispersant is an organic compound having a hydroxyl group and a carboxyl group or a neutralized salt thereof or a lactone thereof, an organic compound having a hydroxymethylcarbonyl group, or an organic compound having an enol form hydroxyl group dissociable as an acid or a neutralized salt thereof. The organic compound has 3 to 20 carbon atoms, with the hydroxyl group being attached to at least 50% of carbon atoms other than the carbon atom forming a double bond with an oxygen atom. Citric acid or a neutralized salt thereof is also useful as the dispersant. The addition of the dispersant facilitates the wetting of the particulate oxide magnetic material with water and improves the dispersion of primary particles and a degree of orientation upon molding.
