摘要： In a method for measuring variations in the output of an internal combustion engine, at least one of signals respectively representing an engine speed, torque, and internal cylinder pressure of the internal combustion engine during the firing strokes of the engine is obtained. A periodical and pulsating change in the obtained signal is detected. A differential value at a portion of the change of the signal having a maximum gradient is then detected. Another method provides measuring variations in the output of the internal combustion engine by calculating the difference between the maximum and minimum values of the change of the obtained signal. Still another method provides measuring variations in the output of the internal combustion engine by correcting the obtained value in accordance with the engine speed. Still another method provides measuring variations in the output of the internal combustion engine by calculating the difference between consecutive changes.

摘要： A torque detector, particularly a torque detector for detecting a torque applied to a torque transmission shaft which is connected to a load such as a wheel of an automobile, comprises a first shaft connected to a driving shaft, a second shaft connected to a torque transmission shaft, and a plurality of elastic members, each of which is interposed between the first shaft and the second shaft for transmitting the torque of the first shaft to the second shaft while receiving the compression force between the first shaft and the second shaft when the driving shaft is driven. The first shaft comprises a flange portion wherein a plurality of long grooves are formed so as to extend in the rotating direction thereof. The second shaft comprises a flange portion wherein a plurality of long holes are formed so as to extend in the rotating direction thereof and penetrate therethrough at such positions as to be substantially opposed to said long grooves. Each of the elastic members is accommodated within each of the long holes. The projecting side portion of each of the elastic members is accommodated within each of the long grooves. The long holes are grouped into two kinds of long holes having different lengths in the rotating direction of the second shaft. One kind of long holes have a length equal to that of the long groove of the first shaft while the other kind of long holes have a length longer than that of one kind of long holes by a predetermined angular distance. Until the applied torque reaches a predetermined value, the first shaft is connected to the second shaft only through one kind of elastic members to decrease the total spring constant thereof and when the applied torque exceeds the predetermined value, the first shaft is connected to the second shaft through all of the elastic members to increase the total spring constant thereof. The torque detector further comprises a data processor by which the angular phase difference between the first shaft and the second shaft, which occurs due to the compression of the elastic members is detected and torque is calculated from the detected angular phase difference.

摘要： An exhaust gas purifying system for internal combustion engines includes a three-way catalyst disposed in the exhaust system of the engine, and secondary air is supplied to the exhaust system through an air control valve under the control of an air-fuel ratio control circuit. The air-fuel ratio control circuit produces a control signal which increases or decreases stepwisely at every reception of a clock signal depending on whether the air-fuel ratio in the exhaust system is above or below a stoichiometric air-fuel ratio. The air control valve is of the proportional electromagnetic type and controls the secondary air passing therethrough in proportion to the control signal.

摘要： An electronically controlled ignition system for internal combustion engines. Reference position detecting means generates reference signals and angular position detecting means generates angular signals indicative of the angular positions of an engine at every predetermined angle of its rotation. Computing means responsive to engine operating condition parameters computers a proper ignition coil energization starting timing data and a proper ignition coil de-energizing timing data. An ignition coil control circuit comprising latch circuits, comparator circuits and counting means converts the ignition coil energization starting timing data and the ignition coil de-energization timing data into pulses having a corresponding pulse width with respect to the rotational angle of the engine to supply an ignition coil energization starting timing signal and an ignition coil de-energizing timing signal to said ignition coil. The computations of the energization starting timing and de-energization timing are initiated in response to the reference signal and the energization starting timing signal, respectively, so that the energization starting timing data is computed by using the de-energization timing data computed in the preceding computation cycle and that the ignition coil control circuit is simplified in circuit construction.

摘要： An electronic ignition timing control system comprises a plurality of double ignition coils each being connected to the spark plugs of each set of two cylinders in a multi-cylinder engine. In addition to a large number of teeth on the periphery of the engine ring gear, there is provided a reference tooth at a predetermined angular crankshaft position for a selected set of the cylinders. The reference angular positions for the other sets of the cylinders are calculated arithmetically. A circuit including read-only-memories determines a desired ignition angle in accordance with engine operating parameters to produce a binary code signal consisting of higher order bits and lower order bits. A first comparator starts to count the number of teeth on the ring gear at the time of the detection of a reference angular position to roughly determine the ignition timing, the first comparator producing an output signal when the count value thereof reaches that of the higher bits. A second comparator starts to count the number of clock pulses of fixed frequency in response to the output signal of the first comparator to finely determine the ignition timing, the second comparator producing an ignition signal when the count value thereof reaches a value corresponding to a fractional ignition angle represented by the lower order bits.
