摘要： When the opening angle of an intake control valve is limited to a given opening angle by fuel cut, an EGR apparatus is activated, and a malfunction of the EGR apparatus is diagnosed on the basis of a change in intake manifold pressure before and after the activation of the EGR apparatus. When the control for reducing the intake-manifold negative pressure is not implemented, the change of the intake manifold pressure is corrected with a changing amount of first reference intake pressure (P(Ne)) changed by engine speed Ne. When the control for reducing the intake manifold genitive pressure is implemented, the change of the intake manifold pressure is corrected with a changing amount of second reference intake pressure (PL(Ne)) changed by engine speed Ne.

摘要： Prior to failure determination of a three-way catalyst, which is carried out on the basis of a reverse frequency ratio of upstream and downstream O2 sensors, deterioration determination is performed at the point when the reverse frequency ratio of the O2 sensors starts to increase, and low NOx control is then implemented. The implement of the low NOx control makes it possible to compensate for the deterioration of the three-way catalyst with respect to NOx purification and to keep NOx emissions from the three-way catalyst equal to or less than the regulation value.

摘要： In a combustion control device for an internal combustion engine provided with a plurality of fuel injection modes having different target air-fuel ratios, threshold values for detecting deterioration of combustion in the internal combustion engine are determined separately for each fuel injection mode depending on features of variation of combustion in the internal combustion engine in each fuel injection mode. Quantity of variation of combustion in the internal combustion engine is, for example, detected in the form of revolution angular acceleration or revolution angular acceleration deviation of the engine. The detected quantity of revolution fluctuation is compared with a threshold value in the currently chosen fuel injection mode. Thus, deterioration of combustion is surely judged according to each fuel injection mode. In particular, threshold values in a compression stroke injection mode are determined to be larger than threshold values in an intake stroke injection mode. A threshold value in the compression stroke injection mode is so determined as to substantively correspond to a complete misfire state of the engine, and threshold values in the intake stroke injection mode consist of a first threshold value substantively corresponding to a complete misfire state of the engine and a second threshold value substantively corresponding to an unstable combustion state of the engine.

摘要： An ignition timing control system for an internal combustion engine of the spark ignition type such as a gasoline engine. A throttle opening of the engine is sampled and a throttle opening variation is calculated. A real volumetric efficiency is calculated based on a real intake air amount and a real engine rotational speed by a real volumetric efficiency calculating device and the real volumetric efficiency is corrected based on the throttle opening variation by a volumetric efficiency correcting device to calculate an effective volumetric efficiency. An ignition timing is set in accordance with the effective volumetric efficiency and the engine rotational speed by an ignition timing setting device and an ignition timing controlling signal is developed based on the ignition timing set by the ignition timing setting device. An igniting device operates upon reception of the ignition timing controlling signal. When the real volumetric efficiency exceeds, particularly upon acceleration of the engine, a predetermined threshold value corresponding to a throttle opening around the full open value, the sampling operation is inhibited. Knocking upon acceleration can thus be prevented with certainty while preventing interference with quick acceleration of the engine.
