  • Patent number: 8972153
    Abstract: In an idling control apparatus for a vehicle, normally, when a predetermined idling reduction execution condition is satisfied, a signal is output to the engine control device so as to execute idling reduction for stopping the idling operation of an engine to automatically stop it. Further, it is determined whether or not a subject vehicle is stopped against an obstacle for avoidance of danger based on at least one of environmental information in front of the subject vehicle, obstacle information and a driving condition of the subject vehicle before it is stopped. When it is determined that the subject vehicle is stopped against the obstacle for avoidance of danger, automatic engine stop is prohibited.

  • Patent number: 8960162
    Abstract: The invention relates to an activated charcoal filter (10) for storing and releasing gaseous hydrocarbons which originate from a fuel supply means of a motor vehicle. The activated charcoal (14) can be supplied with gaseous hydrocarbons via an inlet (16). A heating means for heating of the activated charcoal (14) is made available by a tank shutoff valve (18) by means of which the inlet (16) can be shut off. Since the tank shutoff valve (18) is being operated as a heating means, an additional heating means for regenerating the activated charcoal (14) can be omitted. Furthermore, the invention relates to a motor vehicle with such an activated charcoal filter (10) and a method for operating an activated charcoal filter (10).

  • Patent number: 8950373
    Abstract: A ring gear is connected to a crank shaft of an engine. A pinion is placed to face to the ring gear. When the engine is started, an ECU performs cranking of the engine under a state where the ring gear and the pinion are in mesh. The ECU releases the mesh state of the ring gear and the pinion after completion of the cranking of the engine. In particular, the ECU performs dispersion control to increase a degree of dispersion of a mesh portion of the ring gear which is meshed with the pinion when the rotation of the ring gear is stopped according to the engine stop. The dispersion control prevents the mesh portion of the ring gear and the mesh portion of the pinion from progressing abrasion and avoiding defect.

  • Patent number: 8948999
    Abstract: A method of stoichiometrically operating a diesel-fueled internal combustion engine. During a main (conventional) fuel injection event, fuel is injected into the cylinders. The air-fuel ratio during this main fuel injection event is stoichiometric. The cylinders are operated by either advancing the exhaust valve closing or modifying the phasing of the exhaust and intake valve lift events, to achieve a negative valve overlap period between the end of the exhaust phase and the beginning of the intake phase of the engine cycle. Fuel is injected into the cylinders during the negative valve overlap period, which results in highly reactive fuel and reduces ignition delay during the main fuel injection event.

  • Patent number: 8919330
    Abstract: A number of systems and methods are disclosed which increase the replenishment interval for anti-knock fluid. This is especially important during activities which require a large amount of anti-knock fluid, such as towing. In some embodiments, the systems and methods are used to reduce anti-knock fluid consumption. For example, changes to engine operation, such as rich operation, spark retarding, upspeeding, and variable valve timing, all serve to reduce the amount of anti-knock fluid required to eliminate knocking. In other embodiments, the composition of the anti-knock fluid is modified, such as by using a higher octane fluid, or through the addition of water to the anti-knock fluid. In other embodiments, the replenishment interval is increased through a larger anti-knock fluid storage capacity. In one embodiment, a three tank system is used where the third tank can be used to store gasoline or anti-knock fluid, depending on the driving conditions.

    Abstract: A control apparatus for an internal combustion engine is provided that can precisely reflect requirements relating to performance of the internal combustion engine in a control amount of each actuator by compensating for weaknesses in the so-called torque demand control. A requirement value of each of torque, efficiency, and an air-fuel ratio, and engine information are inputted to an engine inverse model. The engine inverse model is then used to calculate actuator requirement values for achieving those requirement values. An actuator direct requirement value directly required of each of actuators is also acquired. Control of the actuators is adapted to be changed between that according to the actuator requirement value and that according to the actuator direct requirement value.

  • Patent number: 8812219
    Abstract: The present invention provides a control apparatus used in an internal combustion engine that can switchably use a compressed natural gas and gasoline. The control apparatus carries out a miss fire check on the internal combustion engine over two or more combustion cycles, and, based on the results of the check, detects failures. The control apparatus prohibits switching of fuels (S23, S24, S28) basically during the miss fire check. If the value of a miss fire counter is not increasing, the control apparatus predicts that a negative check result will not be obtained (S26), and lifts the prohibition on switching of fuels (S29).
