  • Patent number: 9828948
    Abstract: Methods and systems are provided for accurately determining the composition of a knock control fluid using sensors already present in the engine system. An intake oxygen sensor is used to estimate the water and the alcohol content of a knock control fluid that is direct injected into an engine cylinder responsive to an indication of abnormal combustion. A change in the pumping current of the oxygen sensor due to the water content of the knock control fluid is distinguished from a change in the pumping current of the oxygen sensor due to the alcohol content of the knock control fluid, while compensating for interfering effects of intake air diluents on the change in pumping current.

  • Patent number: 9745905
    Abstract: Methods and arrangements are described for controlling transitions between firing fractions during skip fire operation of an engine in order to help smooth the transitions. Generally, firing fractions transitions are implemented gradually, preferably in a manner that relatively closely tracks manifold filling dynamics. In some embodiments, the commanded firing fraction is altered each firing opportunity. Another approach contemplates altering the commanded firing fraction by substantially the same amount each firing opportunity for at least a portion of the transition. These approaches work particularly well when the commanded firing fraction is provided to a skip fire controller that includes an accumulator functionality that tracks the portion of a firing that has been requested, but not delivered, or vice versa.

  • Patent number: 9410494
    Abstract: A method of assessing the functioning of an EGR cooler of an EGR system in an internal combustion engine, wherein the EGR cooler can be selectively operated in a first and a second operating condition; and wherein the engine comprises at least one cylinder equipped with a pressure sensor. The assessment of the functioning of the EGR cooler is based on the variation of a combustion characteristic value depending on cylinder pressure (CA50), upon switching of the EGR cooler from a first to a second operating condition.

  • Patent number: 9410453
    Abstract: Methods and systems are described for an engine with a cam torque actuated variable cam timing phaser. Phaser positioning control is improved by reducing inaccuracies resulting from inadvertent spool valve and/or phaser movement when the spool valve is commanded between regions. In addition, improved spool valve mapping is used to render phaser commands more consistent and robust.

  • Patent number: 9404445
    Abstract: An evaporated fuel treatment apparatus includes a diagnosis section for leak diagnosis of an evaporated fuel tightly-closed system. In first diagnosis stage in which an atmosphere on-off valve is in close state after an ignition switch is turned off, the diagnosis section performs first leak diagnosis, based on relationship between tank internal pressure detected by a tank internal pressure sensor and first threshold value; and in second diagnosis stage in which the atmosphere on-off valve is in close state after completion of first leak diagnosis, the diagnosis section performs second leak diagnosis, based on relationship between tank internal pressure detected by the tank internal pressure sensor and second threshold value. The atmosphere on-off valve is once opened after completion of first leak diagnosis. First threshold value is set with larger deviation from the atmospheric pressure compared with second threshold value used in second diagnosis stage.

  • Patent number: 9399964
    Abstract: In one aspect, a method for controlling operation of an internal combustion engine is described. The engine is operated in a skip fire manner such that selected skipped working cycles are skipped and selected active working cycles are fired to deliver a desired engine output. A particular level of torque output is selected for each of the fired working chambers. Various methods, arrangements and systems related to the above method are also described.

  • Patent number: 9389143
    Abstract: One or more testing devices used for a test, a device management apparatus that is communicably connected to the testing devices to manage the testing devices, and an automatic test management apparatus that sets a schedule of the test, and on the basis of the schedule, issues a command to the device management apparatus are provided. The device management apparatus is provided with a disconnecting/connecting operation sensing part that senses that a disconnecting/connecting operation for connecting or disconnecting any of the testing devices has been performed; and a management main body part that, in the case where the disconnecting/connecting operation sensing part detects a connecting operation, starts a predetermined connecting protocol for establishing a connecting state and starts management of the testing device, as well as in the case where the disconnecting/connecting operation sensing part detects a disconnecting operation, canceling the connection to terminate the management of the testing device.

  • Patent number: 9382856
    Abstract: A system for fuel injection control in internal combustion engine is provided. Fuel is injected during exhaust stroke from a fuel injector for port injection upstream of an intake valve. In-cylinder temperature as the engine cylinder undergoes compression is predicted. Fuel is injected during intake stroke from the fuel injector to supply fuel to the inside of the cylinder upon determining that the predicated in-cylinder temperature is greater than a temperature beyond which pre-ignition is expected to happen.

  • Patent number: 9353695
    Abstract: A control device acquires various requests concerning the performance of an internal combustion engine and sets a request-specific constraint on a control amount value. The constraint is expressed as a set of constraint index values assigned to individual control amount values, and the distribution of the constraint index values is varied in accordance with the type of a request. The control device integrates the constraint index values for each control amount value and then, in accordance with the distribution of the integrated constraint index value for a control amount, determines a limitation of the control amount. The control device determines a target control amount value within the limitation and controls the internal combustion engine in accordance with the target control amount.

  • Patent number: 9346488
    Abstract: An electronic control system in which a sensor transmits a data to a control unit is provided. In one embodiment, the sensor includes a first detector and a second detector each converting a physical quantity of a detection target into a digital data. An output portion of the sensor outputs in turn a normal data and a monitor data associated with each other. The normal data is the digital data outputted from the first detector, and the monitor data is a reversed data of the digital data outputted from the second detector. The control unit determines that at least one of the first detector, the second detector and the output portion has failure when the reversed data does not match the normal data.

  • Patent number: 9322367
    Abstract: Methods and systems are provided for estimating a fuel canister purge flow based on outputs of an intake manifold oxygen sensor. For example, during boosted engine operation when exhaust gas recirculation (EGR) is flowing below a threshold and purge is enabled, purge flow may be estimated based on changes in the sensor output while modulating a canister purge valve between an open and closed position. Then, during subsequent operation wherein EGR and purge flow are enabled, the output of the sensor may be adjusted based on the estimated purge flow.

  • Patent number: 9316163
    Abstract: An object of the present invention is to enable a requested efficiency by cylinder group that is requested from a viewpoint of exhaust gas performance to be realized precisely when an internal combustion engine having a single throttle shared by a plurality of cylinder groups, and having an exhaust gas purifying catalyst for each of the cylinder groups is operated at a different air-fuel ratio at each of the cylinder groups. To this end, a control device for the internal combustion engine provided by the present invention calculates an efficiency ratio of a representative efficiency determined based on the requested efficiency by cylinder group and a requested efficiency by cylinder group, and calculates a requested torque by cylinder group by dividing a requested torque by the efficiency ratio for each of the cylinder groups.
