摘要： An engine control device, which is adapted for an engine provided with an NOx-absorbing material arranged in an exhaust passage for absorbing NOx in an oxygen-rich atmosphere, and releasing NOx and absorbing sulfur content when the oxygen concentration drops, includes a discriminator for judging whether the amount of sulfur absorbed by the NOx-absorbing material has reached a prescribed quantity, and a reductant concentration controller which increases the temperature of the NOx-absorbing material by decreasing a quantity related to EGR ratio for desulfurizing the NOx-absorbing material based on the result of judgment made by the discriminator. When the quantity related to the EGR ratio is decreased, the temperature of exhaust gas increases. Consequently, the temperature of the NOx-absorbing material increases and the sulfur in the NOx-absorbing material is freed and released.

摘要： An exhaust gas purifying apparatus comprises a control unit (29) operative to estimate an amount of NOx absorbed by a NOx trap material (17) disposed in an exhaust passage (10) and to make an air-fuel ratio richer so as thereby to cause the NOx trap material to release sulfur when the estimated amount of NOx absorption exceeds a specified amount. Further, the control unit (29) operative to estimate an amount of sulfur absorbed by the NOx trap material (17) and to make an air-fuel ratio richer and rising a temperature of exhaust gas so as thereby to cause the NOx trap material to release sulfur when the estimated amount of sulfur absorption exceeds a specified amount. The control unit restricts an air-fuel ratio from being made richer when the NOx trap material is not expected to absorb NOx due to progress of sulfur absorption resulting from conditionally the sulfur releasing.

摘要： A catalyst (17) of a NOx absorbing-and-reducing type is disposed in an exhaust passage (10) of an engine (1). The catalyst (17) absorbs a NOx component in an exhaust gas under an over-oxygen atmosphere and reductively emits the absorbed NOx component according to reduction of oxygen concentration. A control unit (20) of the engine (1) estimates a momentary amount of the absorbed NOx component, and further estimates an integrated amount of the absorbed NOx component according to the integration of the momentary amounts. Then the control unit (20) lets the catalyst (17) to emit the NOx component when the integrated amount is equal to or greater than a predetermined absorption amount. In addition, the control unit (20) corrects the momentary amount to a smaller value in adverse proportion to the increase in the integrated amount.

摘要： A start control device includes a compression self-ignition engine, fuel injectors, a piston stop position detector, a starter motor and a controller for automatically stopping the engine when a predetermined automatic stop condition is satisfied, and thereafter, when a predetermined restart condition is satisfied and a compression-stroke-in-stop cylinder piston stop position is within a reference stop position range set relatively on a bottom dead center side, restarting the engine by injecting the fuel into the compression-stroke-in-stop cylinder while applying the rotational force to the engine using the starter motor. In restarting the engine, when the fuel is injected in the compression-stroke-in-stop cylinder, the controller controls the fuel injector to perform a pre-injection before a main injection and increase a total injection amount of the fuel for the pre-injection as the stop position of the compression-stroke-in-stop cylinder piston is further on a top dead center side.

摘要： An engine starting system includes a throttle valve, an alternator, an engine speed sensor and an electronic control unit (ECU). The ECU functionally includes an automatic engine stop controller for automatically stopping the engine by interrupting fuel injection when predefined automatic engine stop conditions are satisfied, and an automatic engine restart controller for automatically restarting the engine when predefined engine restart conditions are satisfied. The automatic engine stop controller sets the quantity of intake air at a level higher than a minimum quantity of intake air necessary for keeping the engine running, decreases the amount of electric power generated by the alternator in an early part of automatic engine stop control operation, and decreases the quantity of intake air and causes the alternator to once decrease the amount of electric power generated thereby at a point in time when the engine speed drops down to a predetermined reference engine speed, and causes the alternator to later increase the amount of electric power generated thereby.
