  • Patent number: 10859020
    Abstract: In a method for reducing particulate emissions of an internal combustion engine during a cold start of the internal combustion engine, the combustion chamber temperature and the ambient temperature are determined. A cold start condition is recognized when the combustion chamber temperature is below a first threshold temperature and the ambient temperature is below a second threshold temperature. In this case, the internal combustion engine is dragged by means of the starter, wherein air that is present in the combustion chambers is compressed and heated. This heat is discharged to the combustion chamber walls, which are likewise heated up. In this operating situation there is no fuel injection in the combustion chambers and no ignition, so that no combustion takes place in the combustion chambers and the internal combustion engine compresses solely fresh air. The combustion chambers heat up due to the compression work, thus achieving better evaporation of the fuel in the combustion chamber.

  • Patent number: 9506412
    Abstract: It is an object of this invention to restrain blow-by gas from reaching a catalyst during fuel cutoff, and protect the catalyst while coping with an increase in oil dilution amount resulting from the use of alcohol fuel, in an internal combustion engine that uses the alcohol fuel. An engine is equipped with a PCV mechanism that introduces blow-by gas in a crankcase into an intake system. Besides, when fuel cutoff is executed with the PCV mechanism in operation, an opening degree of a throttle valve during fuel cutoff is set on the basis of an oil dilution amount in lubricating oil. Thus, the throttle opening degree during fuel cutoff is adjusted in accordance with a generation amount of blow-by gas, so that an intake negative pressure can be appropriately reduced. Accordingly, during fuel cutoff, the amount of blow-by gas that is sucked out from the crankcase due to the intake negative pressure and introduced into the intake system can be held small.

  • Patent number: 9239022
    Abstract: Disclosed is an internal-combustion engine controller capable of improving emission characteristics at a start of an internal-combustion engine. When injection during an exhaust stroke is controlled in a port-injection engine, the engine controller ECU performs the first fuel injection during t1 to t2 according to a memory-based crank angle as illustrated in FIG. 12(b) at a fuel injection timing before determination of an actual stroke. Thus, the injected fuel has been introduced into a cylinder during the actual stroke. If fuel is not injected during t1N to t3N within the next exhaust stroke as denoted by the solid line, this causes misfire in the cylinder, so that the engine rotation at the start cannot be smooth. Thus, the ECU clears a finished fuel injection flag (F_INJ) at an incorrect crank angle storage determination timing (tJUD) as denoted by the dashed-dotted line, thereby capable of controlling the fuel injection.

  • Patent number: 9080525
    Abstract: A method adjusts fuel injection based on a fuel make-up, such as a fuel ethanol content. The fuel make-up may be learned during transient conditions by correlating transient fueling effects caused by the different evaporation rates of higher and lower ethanol content to measured exhaust air-fuel ratio. In this way, an ethanol content independent of combustion stoichiometry can be obtained, even during transients, that is less sensitive to part variation and sensor drift.

  • Patent number: 9074573
    Abstract: In a system, a predictor predicts a future trajectory of a rotational speed of a crankshaft during drop of the crankshaft's rotational speed in a forward rotational direction due to automatic stop of an engine. An engaging unit shifts, in response to when an engine restart condition is met during the drop of the crankshaft's rotational speed, a pinion to a ring gear for engaging the pinion with the ring gear. An engagement determiner determines, based on the future trajectory of the crankshaft's rotational speed, whether the pinion and the ring gear will be shifted to engagement state therebetween during reverse rotation of the output shaft. A controller controls, based on a result of the determination by the engagement determiner, at least one of: a start timing to shift the pinion to the ring gear by the engaging unit, and a start timing to energize the motor.

  • Patent number: 9026344
    Abstract: At the time of an engine start while the vehicle is driving, when a required vehicle driving force (TRQ) is smaller than or equal to a predetermined value (TRQth), an electronic control unit (20) estimates that the degree of deformation of a mount (11) is smaller than or equal to a predetermined degree and sets a second-cycle fuel injection amount (Q2) so as to be larger than a first-cycle fuel injection amount (Q1) at the time of the engine start. On the other hand, when the required vehicle driving force (TRQ) is larger than the predetermined value (TRQth), the electronic control unit (20) estimates that the degree of deformation of the mount (11) is larger than the predetermined degree and sets the first-cycle fuel injection amount (Q1) so as to be larger than the second-cycle fuel injection amount (Q2) at the time of the engine start.
