摘要： In an engine having a premixed combustion mode, an EGR flow rate estimating precision is deteriorated at a transient time, and a torque fluctuation and an exhaust gas deterioration are caused. In an engine control apparatus having a premixed combustion mode and a diffusion combustion mode, a sensor detecting an EGR flow rate is arranged in an EGR flow path of the engine, and a cylinder state of the engine is estimated by using an output value of the sensor detecting the EGR flow rate at a time when the engine is in the premixed combustion mode. Since it is possible to accurately detect the EGR flow rate at the transient time and feed back the EGR flow rate at a high response, it is possible to prevent a torque fluctuation and an exhaust gas deterioration.

摘要： A plurality of spark electrodes are disposed in an arc shape on the surface or so as to be projected from the surface of an insulating member formed on a part of the wall face of a combustion chamber, and are formed so as to be in series electrically via discharging gaps.A spark plug is provided integrally with an injector, and the spark plug and the ignition coil are integrated. The three members are constructed as an integral unit, thereby improving installability to an engine.

摘要： An exhaust recirculation control system of the internal combustion engine computes an oxygen concentration in total intake air containing recirculation exhaust gas in a cylinder and the ratio between an oxygen quantity in the total intake air and a fuel injection quantity (oxygen quantity/fuel injection quantity ratio). The computed values are compared with target values which are pre-set according to engine operating conditions and, based on the result of the comparison, at least an EGR valve or a fuel injection quantity. In order to perform such a control with high accuracy, a correcting means corrects a recirculation exhaust gas mass flow signal from a gas mass flowmeter on the basis of a predicted exhaust gas component concentration. And, by using the corrected recirculation exhaust gas mass flow, oxygen concentration in total intake air containing the recirculation exhaust gas in the cylinder and the ratio between the oxygen quantity in the total intake air and the fuel injection quantity (target oxygen quantity/fuel injection quantity ratio) are computed to perform EGR control.
