  • Patent number: 10476083
    Abstract: A length L between the markings 11a measured by the pre-coating thickness measuring device 17 and a length L? between the markings 11a measured by the post-coating thickness measuring device 18 are calculated, and a length ratio is obtained. Measurement positions of thickness data measured by the post-coating thickness measuring device 18 are corrected based on the calculated length ratio. A value at each measurement position of pre-coating thickness information on a corrected post-coating thickness interpolation line connecting measurement points of corrected post-coating thickness information obtained by correcting the measurement positions with a line segment is determined as post-coating thickness at each measurement position. A difference between the determined value and the pre-coating thickness is calculated. If it is in a predetermined range, the electrode is determined as a non-defective product.

  • Patent number: 7644701
    Abstract: A preset waiting period is previously set on the basis of a signal in correspondence to a detection of a start point of a detection of a no-tooth portion of a signal rotor. In the case of a control for injecting a fuel after the preset waiting period has elapsed, an output of a signal indicating a start point of an actual detection of the no-tooth portion by a waveform shaping portion is delayed due to the existence of the no-tooth portion. A control computer corrects the preset waiting period to be shorter by an amount corresponding the delay. Accordingly, an accuracy of a fuel injection start timing control is improved.

  • Patent number: 7540146
    Abstract: Cylinder heads are each provided with a fuel injection valve, and an addition nozzle for adding fuel for activating an exhaust purifying catalyst to an exhaust manifold. There exists a non-exhaust period in which an exhaust gas does not flow out to exhaust passages from the exhaust manifolds during an operation of an engine. An ECU controls the addition nozzles in such a manner that the addition nozzles execute a fuel addition during periods except the non-exhaust period. Accordingly, the fuel added to the exhaust manifolds for activating the catalysts is avoided from collecting on a wall surface of an exhaust system without getting on an exhaust stream.

  • Patent number: 7360356
    Abstract: A main control computer commands a second sub-control computer to perform a reduced-cylinder operation when the coolant temperature detected by a coolant temperature sensor is greater than or equal to a reference temperature, and the exhaust temperature detected by a temperature sensor is less than a reference exhaust temperature and is within a reduced-cylinder operation allowable range in which a combination of the engine speed and the engine load is set in advance. The second sub-control computer deactivates a second cylinder group based on a command of the reduced-cylinder operation.

  • Patent number: 7353102
    Abstract: An internal combustion engine includes parallel first and second intake passages, and the intake passages respectively include first and second superchargers. A first airflow meter measures the intake air amount in the first intake passage. A second airflow meter measures the intake air amount in the second intake passage. An ECU obtains an air amount difference between the intake air amount measured by the first airflow meter and the intake air amount measured by the second airflow meter to compare the obtained air amount difference with a predetermined abnormality determination value. The ECU determines that an abnormality has occurred in one of the superchargers when the air amount difference exceeds the abnormality determination value. The abnormality determination of the superchargers is based on the air amount difference between the intake passages. This accurately determines the occurrence of an abnormality in the superchargers regardless of structure of the intake passages.

  • Publication number: 20070172397
    Abstract: Collectors are provided on a pair of exhaust passages extending in parallel from an internal combustion engine respectively. Each of the collectors collects black smoke particles (unclean substance) included in exhaust gas. One of a pair of differential pressure detectors detects a first differential pressure between upstream and downstream of one of the collectors while the other differential pressure detector detects a second differential pressure between upstream and downstream of the other collector. Upon finishing a regeneration process of removing the black smoke particles in each of the collectors, a control computer estimates an exhaust gas flow rate of each of the exhaust passages based on the first differential pressure and the second differential pressure.

  • Patent number: 7066157
    Abstract: A detecting device detects boost condition of each of a plurality of superchargers. The detecting device includes at least two of a pressure ratio detecting unit, which detects the ratio of the pressure downstream each supercharger to the pressure upstream each supercharger; an air flow rate detecting unit, which detects the flow rate of air passing through each supercharger; and a rotational speed detecting unit, which detects the rotational speed of each supercharger. When it is determined that the boost condition of only part of the superchargers is within the surging area, a control unit increases the air flow rate of the supercharger, the boost condition of which is determined to be in the surging area. Therefore, the limitation of the flow rate of air supply is raised.
