  • Publication number: 20180216511
    Abstract: The disclosure is intended to oxidize PM deposited in a filter in a suitable manner. Provision is made for a filter of wall flow type, a temperature raising unit to raise the temperature of the filter from a downstream side thereof, an exhaust gas shut-off valve, and a controller. The controller controls a flow of exhaust gas in the filter by once fully closing the exhaust gas shut-off valve and then fully opening it when the flow rate of the exhaust gas is equal to or larger than a predetermined flow rate, so as to cause PM to move to a downstream side portion in the filter in the direction of flow of exhaust gas, and carries out regeneration processing which oxidizes the PM by using the temperature raising unit after the controller has caused the PM to move to the downstream side portion of the filter.

  • Publication number: 20180216512
    Abstract: An aftertreatment system comprises a SCR system including at least one catalyst. A NOx sensor is positioned down-stream of the SCR system. A controller is configured to determine an estimated engine NOx amount in the exhaust gas produced by an engine fluidly coupled to the aftertreatment system. The controller interprets an output value indicative of a first amount of oxygen in the exhaust gas downstream of the SCR system. The controller determines an adjusted engine NOx amount in response to the output value. A NOx sensor is positioned downstream of the selective catalytic reduction system and communicatively coupled to the controller. The NOx sensor is structured to provide the output value.

  • Publication number: 20180216515
    Abstract: An exhaust duct has a riser duct section which is connected to an exhaust port having such an inlet port at a lower portion of the riser duct section as is connected to an exhaust port for the combustion gas, the exhaust port being opened at a lower portion of the combustion box. The riser duct section extends upward along an external surface of the combustion box. Suppose that a direction normal to the external surface of the combustion box is defined as a front-to-back direction, and a horizontal direction perpendicular to the front-to-back direction is defined as a lateral direction, then the riser duct section is formed into a flat shape having a smaller dimension in the front-to-back direction than the dimension in the lateral direction. Fluctuations in width between front-side and back-side plate parts of the riser duct section are devised to be restrained, and increase in size can be avoided.

  • Publication number: 20180216547
    Abstract: An engine system includes: an engine including a plurality of cylinders; an EGR passage including EGR branch passages each configured to recirculate part of exhaust gas into an intake port of a corresponding one of the plurality of cylinders; an EGR valve configured to be capable of adjusting an EGR flow rate; and an ECU configured to control the EGR valve. When an engine rotation fluctuation amount in an EGR OFF state is less than a first determination value, and when the engine rotation fluctuation amount in an EGR ON state is greater than a second determination value, the ECU imposes an EGR restriction for restricting the EGR flow rate. When it is determined that the engine rotation fluctuation amount in the EGR ON state is greater than a third determination value less than the second determination value after the EGR restriction is imposed, the ECU continues the EGR restriction.

  • Publication number: 20180216549
    Abstract: A control apparatus for an internal combustion engine with a supercharger includes a boost-pressure detector. When first boost pressure control to control the supercharger such that a boost pressure reaches a target pressure starts, starts, the target pressure is set to an initial target pressure, gradually at a first rate, and then gradually increased to a steady-state target boost pressure at a second rate smaller than the first rate if the boost pressure is equal to or higher than a threshold pressure. Second boost pressure control is performed such that the boost pressure reaches a steady-state target boost pressure. Inhibiting/allowing circuitry is configured to inhibit execution of the first boost pressure control and allow execution of the second boost pressure control if the boost pressure is lower than the steady-state target boost pressure and if the steady-state target boost pressure is lower than the threshold pressure.

  • Publication number: 20180216551
    Abstract: A variety of methods and arrangements for improving the fuel efficiency of internal combustion engines based on skip fire operation of the engine are described. In one aspect the skip fire decisions are made on a working cycle by working cycle basis. During selected skipped working cycles, the corresponding cylinders are deactivated such that air is not pumped through the cylinder during the selected skipped working cycles. In some implementations, the cylinders are deactivated by holding associated intake and exhaust valves closed such that an air charge is not present in the working chamber during the selected skipped working cycles.

  • Publication number: 20180216553
    Abstract: A catalyst deterioration determination system effectively prevents erroneous determination caused by increase of the H2 component in exhaust gas and improves accuracy of determination. A LAF sensor and an O2 sensor are provided on the upstream side and downstream side of a three-way catalyst. Deterioration of the three-way catalyst is determined on the basis of an output of the O2 sensor, which is detected during air-fuel ratio switching control in which an air-fuel ratio is alternately switched to the rich side and lean side of the stoichiometric air-fuel ratio according to a detected equivalent ratio detected by the LAF sensor, on the basis of a result of comparison between an oxygen inflow into the three-way catalyst and a lean side-limiting value and a rich side-limiting value which are target values of the oxygen inflow. Fuel injection timing retardation control and/or divided fuel injection control are prohibited during the deterioration determination.

  • Publication number: 20180216554
    Abstract: The invention relates to a method for adapting the composition of a mixture of fuel and combustion air. The mixture is supplied to a combustion chamber of a mixture-lubricated combustion engine in a work apparatus. The fuel is supplied to the combustion engine via a controlled fuel valve. In an operating state (I) of the combustion engine, the quantity of fuel is metered by the fuel valve. For the purpose of adapting the composition of the mixture, the combustion engine is shifted into a special operating state (II) which differs from the normal operating state (I). After starting, the combustion engine is operated in a first rotational speed range (B) for a prespecified operating time (Tmin), wherein, after the prespecified operating time (Tmin) has elapsed, the operating state (II) for adapting the composition of the mixture is initiated by a prespecified user action.
