摘要： An internal combustion engine has a particulate filter for collecting exhaust particulate matters included in exhaust gas. An oxidization catalyst is supported on the particulate filter. A fuel injection control system for the engine has injection quantity setting means. The injection quantity setting means sets an injection quantity for a post-injection so that the injection quantity is increased toward a basic injection quantity corresponding to a heating value, which is suitable for eliminating exhaust particulate matters collected by a particulate filter. The injection quantity is gradually increased to the basic injection quantity while maintaining temperature of the particulate filter including the oxidization catalyst above a lower limit temperature for inhibiting generation of white smoke. The lower limit temperature is determined in accordance with the injection quantity.

摘要： A travel assist system searches a nearest service station based on navigation information and predicts a quantity of aqueous urea solution consumed until the service station is reached. If a quantity of the remaining aqueous urea solution is not greater than the aqueous urea solution consumption at least by a predetermined value, a warning is provided to a user. Control conditions of an internal combustion engine (diesel engine) enabling the vehicle to reach the service station without running short of the aqueous urea solution are calculated. An exhaust gas recirculation quantity is increased based on the calculation result. Thus, nitrogen oxides contained in the exhaust gas is reduced and a consumption of the aqueous urea solution is reduced.

摘要： A DPF is used in an internal combustion engine for trapping PM discharged from an engine body. Presence and absence of an abnormality in the DPF is evaluated using differential pressure, which is between the front and the rear of the DPF. The differential pressure considerably decreases or considerably increases due to breakage or plugging of the DPF in an exhaust emission control device. The abnormality in the DPF is evaluated when a large deviation arises between a PM amount calculated in accordance with differential pressure, which is between the front and the rear of the DPF, and a PM amount calculated through integration of a PM discharge amount measured in accordance with an engine operating state. Thereby, presence and absence of the abnormality such as plugging and breakage in the DPF can be correctly detected.

摘要： A gas sensor control apparatus for an exhaust gas sensor working to measure a selected component of exhaust gas from a diesel engine. The apparatus consists of a heater to heat the exhaust gas sensor to activate it and a controller working to restrict an operation of the heater in the condition that drops of water are expected to exist in an exhaust system of the engine. The controller determines whether the condition in which the temperature of the exhaust gas sensor is expected to be lower than that of the exhaust gas is met or not based on an operating condition of the diesel engine. When the temperature condition is met, the controller elevates the temperature of the exhaust gas to promote heating of the exhaust gas sensor through the heater, thereby minimizing the deterioration in characteristics or performance of the exhaust gas sensor.
