摘要： A temperature sensor disposed in an exhaust system of an engine is inspected. Determination is made that conditions for inspecting the temperature sensor are satisfied in the current engine load range. The time for the temperature in the exhaust system to reach a value appropriate for checking the temperature sensor is determined in accordance with engine water temperature. Output of the temperature sensor is checked to determine if the temperature sensor is normal at the determined time.

摘要： An exhaust emission control system for an internal combustion engine with a filter provided in the exhaust system of the engine, for collecting particulates from exhaust gases. An ECU carries out the post injection for additionally injecting fuel into a combustion chamber of the engine after a combustion stroke of the engine to thereby perform a regeneration operation for regenerating the filter. A vehicle speed sensor detects a travel distance of a vehicle on which the engine is installed, and the ECU calculates a post injection allowable amount such that the post injection allowable amount increases in accordance with increase in the detected travel distance. During execution of the post injection, the amount of fuel injected through the post injection is subtracted from the post injection allowable amount, and when the post injection allowable amount becomes equal to or smaller than a predetermined first threshold value, the post injection is inhibited.

摘要： In an oil level detection system of an internal combustion engine having a filter to capture particulates in exhaust gas that is burned off by fuel supplied by post injection to be regenerated and having an oil level sensor installed in an oil pan, it is determined whether the engine is under a long idling state and if so, an estimated value of the engine oil level is calculated by correcting output of the oil level sensor by an evaporation amount correction factor. Then, it is determined whether the level of the engine oil is sufficient by comparing the estimated value with a threshold value. With this, it becomes possible to detect the oil shortage without delay.

摘要： An exhaust emission control system for an internal combustion engine, which is capable of not only reliably suppressing post injection for regenerating a filter from causing oil dilution, but also enabling execution of the post injection to a maximum possible extent. The filter is provided in the exhaust system of the engine, for collecting particulates from exhaust gases. An ECU carries out the post injection for additionally injecting fuel into a combustion chamber of the engine after a combustion stroke of the engine to thereby perform a regeneration operation for regenerating the filter. A vehicle speed sensor detects a travel distance of a vehicle on which the engine is installed, and the ECU calculates a post injection allowable amount such that the post injection allowable amount increases in accordance with increase in the detected travel distance. During execution of the post injection, the amount of fuel injected through the post injection is subtracted from the post injection allowable amount, and when the post injection allowable amount becomes equal to or smaller than a predetermined first threshold value, the post injection is inhibited.

摘要： A fuel supply apparatus for an internal combustion engine is disclosed. The fuel supply apparatus includes a fuel pump driven by the engine, a pressure accumulating device for retaining the fuel pressurized by the fuel pump, a relief device which opens when a fuel pressure in the pressure accumulating device exceeds a predetermined upper limit pressure. An injection device is connected to the pressure accumulating device and injects fuel into a combustion chamber of the engine. A fuel pressure in the pressure accumulating device is detected. A discharge amount of the fuel pump is controlled so that the detected fuel pressure coincides with a target fuel pressure. The target fuel pressure is reduced when the detected fuel pressure is equal to or greater than a predetermined fuel pressure, to suppress opening of the relief device.
