摘要： A fuel injection device (fuel supply system) of a common rail type fuel injection system for an engine includes a pressure sensor disposed in a fuel inlet of an injector for measuring a fuel pressure at a position where the sensor is disposed and an ECU for sensing various kinds of pressure fluctuations associated with the injection including a pressure leak due to an injection operation of the injector and waving characteristics due to actual injection thereof based on sensor outputs from the pressure sensor. The ECU serially obtains the sensor outputs from the pressure sensor at intervals of 20 μsec.

摘要： Tooth portions are formed at unit angles on a rotor connected with a crankshaft of an internal combustion engine. A toothless portion is formed on the rotor by irregularly changing the regular arrangement of the tooth portions. A controller of the engine estimates times necessary for rotation of unit angles of an arbitrary angular range of 50° CA including the toothless portion and a pair of tooth portions adjacent to the toothless portion by using times necessary for rotation of unit angles of a different angular range of 50° CA distant from the arbitrary angular range by 180° CA. Thus, the controller can maintain high controllability of the engine even when there occurs a range where the time necessary for the rotation of the crankshaft is not sensed appropriately.

摘要： A malfunction in an operation panel serving as a man-machine interface of electronic apparatus is detected and recovered adequately. A control apparatus stores data to be displayed on a display section in an operation panel in the form of coded information. The display contents of the display section are transmitted to the control apparatus in an inverse data stream according to the predetermined rules or at regular time intervals, so that the stored information is compared with developed data. When there is a discrepancy in data, the display contents are retransmitted, and transmitted in an inverse data stream again for comparison. When there is still a discrepancy in data, the operation panel is initialized, and the display data is transmitted in an inverse data stream once again for comparison. When there is still a discrepancy in data, supply of power to the operation panel is stopped and an alarm is given.
