摘要： The invention relates of a method for determining a combustion state of an internal combustion engine, for detecting an ion current generated within a combustion chamber of the internal combustion engine, including the steps of measuring a characteristic value of the ion current detected during a period that the ion current is generated and a generation period in which the ion current is generated, and determining a combustion state on the basis of a relation between the characteristic value and the generation period with respect to an elapsed time from an ignition, and the method comprises determining that the combustion state is normal, by setting a determination reference to be larger with respect to the characteristic value and shorter with respect to the generation period, in the case that the elapsed time from the ignition is short, and determining that the combustion is normal, by setting the determination reference to be smaller with respect to the characteristic value and longer with respect to the generation period in correspondence that the elapsed time from the ignition becomes longer.

摘要： An EGR apparatus includes a EGR passage for allowing part of exhaust gas discharged from a combustion chamber of an engine to an exhaust passage to flow in an intake passage and recirculate back to the combustion chamber, and an EGR valve provided in the EGR passage to regulate an EGR passage in this passage. The EGR valve includes a valve seat, a valve element to be seatable on the valve seat, and a step motor for driving the valve element to open and close. An electronic control device controls the EGR valve to repeat opening and closing of the valve element between a closing position and a small opening position in order to remove foreign matters adhered to the valve seat or valve element during deceleration fuel cutoff of the engine.

摘要： An EGR apparatus includes a EGR passage and an EGR valve provided in the EGR passage to regulate an EGR flow rate in the EGR passage. An ECU closes the EGR valve from an open state prior to start of deceleration of the engine based on engine rotation speed detected by a rotation speed sensor, accelerator opening degree detected by an accelerator sensor, and actual opening degree of the EGR valve. During deceleration of the engine, the ECU obtains a target opening degree of the EGR valve according to the separately detected engine rotation speed and accelerator opening degree from a target opening degree map and starts to close the EGR valve when a difference between an actual opening degree and the target opening degree of the EGR valve exceeds a predetermined value.
