摘要： In a method and apparatus for controlling a combustion engine, a digital computer is adapted to calculate first and second values corresponding to optimal settings of fuel injectors and spark plugs in a time sequence by detecting changes of the amount of air flowing into the engine and the rotation speed of the engine. The computer is programmed to calculate the first and second values from first and second functions describing desired relationships among each setting of the fuel injectors and the spark plugs, the amount of air flowing into the engine and the rotation speed of the engine. An electronic control circuit in the form of a timer is coupled with the digital computer for generating an electric control signal with a predetermined period of time in response to the setting of the spark plugs and applying the control signal to the computer to halt the calculation of the first value during the predetermined period of time even if the computer is conditioned to calculate the first value, the remaining calculation of the first value being subsequently performed after lapse of the predetermined period of time.

摘要： In response to the input signal corresponding to the rotational speed of an internal combustion engine, a first read-only memory generates a binary coded signal indicative of the corresponding preliminarily written ignition retard angle from a predetermined angular position of the engine crankshaft, and in response to the input signal corresponding to the intake manifold vacuum a second read-only memory generates a binary coded signal indicative of the corresponding preliminarily written ignition retard angle. The output signals of the read-only memories are added together by an adder. A comparator compares the output signal of the adder with the number of clock pulses corresponding to the rotational angle of the crankshaft, and the ignition timing is determined by the output of the comparator.

摘要： An electromagnetic rotary driving device including a rotor of a permanent magnet arranged in a hole formed in a bored stator core block of a stator core, made from magnetic material. The air gap formed between the bored block of the stator core and the rotor in the direction parallel with the magnetic path in the stator core is relatively long, while the air gap formed between the bored block of the stator core and the rotor in the direction perpendicular to the magnetic path in the stator core is relatively short. In this device, the angle of rotation of the rotor is continuously changed by the current flowing through the coil of the stator without requiring a spring for return motion.

摘要： A torque variation in an internal combustion engine due to the combustion variations is detected at each predetermined period. An average torque variation to be compared with the detected torque variation is predetermined experimentally based on the engine speed and the intake manifold pressure and is stored in a memory. The number of the detected torque variations which exceed the average torque variation multiplied by a predetermined constant is counted, and if the ratio of the counted number to the total number of the detected torque variations is larger than a predetermined reference value, then the presence of a torque variation is determined.

摘要： A rotary solenoid actuator for proportionally controlling the flow of fluid, such as air, in a pipe comprises a housing with a rotor rotatably mounted thereon. A stationary coreless coil for generating a magnetic field in response to a control current therethrough is mounted in the housing. A permanent magnet is affixed to a rotatably mounted shaft within the coil, and a return spring is attached to the rotating shaft. Due to low hysteresis in the coreless coil, there is a linear relationship between the control current and the fluid flow.
