摘要: A fuel injection controller of an internal combustion engine decreases a target intake quantity stepwise and increases an opening degree command value of an EGR valve stepwise when the controller switches control to rich combustion control. Accordingly, an intake quantity gradually decreases and an EGR quantity gradually increases, so an oxygen quantity flowing into a combustion chamber (cylinder inflow oxygen quantity) gradually decreases. The injection quantity is gradually increased in accordance with the gradual decrease of the oxygen quantity. Thus, the fuel injection controller can perform processing for making an air fuel ratio rich in order to discharge nitrogen oxides from an occlusion agent while appropriately inhibiting torque fluctuation.

摘要: The internal combustion engine control apparatus includes a calculation function of calculating an energy generation rate of an energy generated by combustion of fuel injected into a combustion chamber of a compression-ignition internal combustion engine, and an ignition detection function of detecting an ignition timing of the fuel in the combustion chamber on the basis of a timing at which the energy generation rate exceeds a first threshold value. When the energy generation rate due to a main injection, which is an object of ignition timing detection by the ignition detection function, exceeds the first threshold value at a plurality of timings, the ignition detection function determines an earliest one of the plurality of the timings as the ignition timing of the main injection.

摘要: An abnormality determination device of a cylinder pressure sensor calculates a gain (sensing sensitivity coefficient) and an offset (bias) indicating an output characteristic of the cylinder pressure sensor. The device determines existence or nonexistence of an abnormality in the gain and the offset respectively. When the device determines that the abnormality exists, the device performs failsafe processing set in modes different from each other between the case of the abnormality in the gain and the case of the abnormality in the offset. As the failsafe processing in the case of the abnormality in the gain, the device performs processing for substantially prohibiting usage of a sensor value of the cylinder pressure sensor in control (fuel injection timing control) by using an alternative value (specified value) instead of the sensor value of the cylinder pressure sensor.

摘要: In a system, an actuator is linked to a valve rotatably installed in a passage through which gas flows. The actuator changes torque to be applied to the valve so as to adjust a rotational position of the valve based on a deviation between a current position and a target position. In the system, a first storing unit stores therein a first threshold. The first threshold is defined in a variation range within which a torque parameter is variable depending on change in the torque to be applied to the valve. The first threshold allows whether there is a possibility that an operation of the actuator is unstable. If the torque parameter substantially shifts either to or through the first threshold in the variation range, a restricting unit restricts variation in the torque parameter with the gas-flow being substantially kept through the passage.

摘要: An ECU converts a cylinder pressure P and a cylinder volume V corresponding to a crank angle θ at least from a compression stroke to a combustion and expansion stroke to a logarithmic value log P and a logarithmic value log V, respectively, to find a logarithmic conversion waveform and estimates a motoring waveform which is obtained by subtracting a pressure rise developed by combustion in a cylinder from the logarithmic conversion waveform, that is, corresponds to a non-combustion state. Further, the ECU computes a determination line Y of an ignition timing Tburn on the basis of the base line X of the estimated motoring waveform and determines the ignition timing Tburn on the basis of this determination line Y and the logarithmic conversion waveform.

摘要: An electronic control unit (ECU) of a fuel injection control system of an internal combustion engine feedback-controls injection timing so that a cylinder pressure maximum value coincides with a target pressure value in an operation range, in which the cylinder pressure maximum value increases as ignition timing advances and torque increases as the ignition timing advances. The ECU feedback-controls the injection timing so that the ignition timing coincides with target timing in another operation range, in which the cylinder pressure maximum value increases as the ignition timing advances but the torque decreases as the ignition timing advances. Thus, the torque can be outputted efficiently by selecting the appropriate feedback control in accordance with the operation range.

摘要: Disclosed is an alignment mark for the X directional alignment of a chip area on a semiconductor wafer, for example. The alignment mark comprises recesses and projections formed on a semiconductor substrate. The recesses or projections are repeatedly arranged in the X direction. The X directional width of the recesses or projections is set smaller than the X directional width of a grain on a metal film formed on the recesses and projections or the average particle size, as viewed from above the semiconductor substrate. The projections may be formed by an insulating layer formed on the semiconductor substrate.

摘要: An air-fuel ratio control apparatus in which an air-fuel ratio of a mixture gas supplied to an engine, especially, a gas engine, is controlled in accordance with an output signal of each of oxygen concentration sensors disposed in upper and lower streams of an exhaust gas catalyzer of the engine. The output signal of the oxygen concentration sensor disposed on the upper stream side of the catalyzer is provided as one input signal of an air-fuel ratio control unit and the output signal of the oxygen concentration sensor disposed on the lower stream side of the catalyzer is provided as an input signal of an output signal correction amount determination unit, respectively. A mixing member for mixing an exhaust gas is disposed in an upper stream of each oxygen concentration sensor to detect the concentration of oxygen in the exhaust gas which is well mixed. The air-fuel ratio control unit controls an air-fuel ratio of a mixture gas in accordance with the output signal of the oxygen concentration sensor disposed on the upper stream side of the catalyzer and an output signal correction amount which is an output signal of the output signal correction amount determination unit. Since the exhaust gas is sufficiently mixed by the mixing member, variations of a measured value caused by the attachment position of each oxygen concentration sensor ar eliminated, thereby making it possible to control the air-fuel ratio of the mixture gas to a value close to a theoretical air-fuel ratio with a satisfactory precision.

摘要: A knock control system for an internal combustion engine has a knock discrimination level. If an output signal from a knock sensor is higher than the knock discrimination level, then the knock control system determines that the engine is subjected to knock and retards the ignition timing. If the knock sensor output signal is lower than the knock discrimination level, i.e., if no knock or detonation is detected over a prescribed period of time, then the ignition timing is advanced. The knock discrimination level is corrected such that a probability that the maximum value of the knock sensor output signal will exceed the knock discrimination level is greater in a knock control range than outside of a knock control range.
