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： A non-linear operational circuit with reference voltage sources and switching means, wherein the output voltage of the operational circuit is compared with the reference voltages to open and close the switching means in accordance with their magnitudes relative to one another and thereby to non-linearly vary the output voltage of the operational circuit in response to changes in the input voltage. The reference voltage sources and the switching means are connected in series between the output terminal and the ground terminal of the operational circuit, whereby at the inflection point at which the ratio of the change in the output voltage of the operational circuit to the change in the input voltage changes, the output voltage is caused to change continuously.

摘要： An intake air amount detecting system includes a branch pipe disposed in the intake manifold of the engine and having two passages each provided therein with a temperature responsive resistor. One of the two passages is provided with an electric heater and a voltage is applied to the electric heater so that the temperature difference in the two passages measured by the two temperature responsive resistors is maintained at a predetermined value irrespective of the amount of air flow through the intake manifold. An A-D converter is further provided and includes a time constant circuit and a capacitor for producing across the capacitor a reference voltage which has a waveform representing a predetermined relationship between the voltage applied to the electric heater and the amount of intake air flow. The voltage actually applied to the heater is compared with the reference voltage at a voltage comparater in the A-D converter and the A-D converter produces a pulse signal having a time width corresponding to a period from the rise of the reference voltage until the reference voltage reaches the actual voltage, and hence corresponding to the amount of intake air flow.

摘要： A thermally-sensitive resistor is positioned in each of two separate passages provided in the intake pipe of an internal combustion engine, and an electric heater is positioned upstream of one of the thermally-sensitive resistors with respect to the direction of flow of intake air. The thermally-sensitive resistors form, along with two reference resistors, a bridge circuit which converts the difference between the resistances of the thermally-sensitive resistors caused by the electric heater, i.e., the difference between the temperatures in the passages to a voltage difference. A control circuit controls the voltage across the electric heater in such a manner that the said voltage difference is maintained constant and thus the amount by weight of intake air can be directly obtained. The input voltages to the thermally-sensitive resistors are applied in the form of pulses through an oscillator circuit thereby reducing the problem of drift of the bridge circuit.

摘要： An opening is provided for an exhaust bypass pipe that bypasses an exhaust turbine of an exhaust turbine supercharger. According to the opening, an exhaust gas amount bypassing the exhaust turbine is calculated. An exhaust gas amount supplied to the exhaust turbine is found by subtracting the waste-gate-valve-passing gas amount from an intake air amount (exhaust gas amount) detected by the air flow meter. A rotational speed of the exhaust turbine is calculated from this turbine-supplied gas amount. An estimated boost pressure is calculated from this rotational speed of the exhaust turbine. Consequently, a boost pressure can be accurately estimated without using a boost pressure sensor even under such conditions as to disable detection of boost pressures or degrade the detection accuracy in a system using a conventional boost pressure sensor.

摘要： A control mode of an intake valve lift controller is changed between a low-speed mode and a high-speed mode. Based on the control mode, an ignition timing is adjusted. When a knocking is detected by a knock sensor after the control mode is changed from the low-speed mode to the high-speed mode, it is determined that the intake valve lift controller has a malfunction in which the intake valve lift controller is stuck in the low-speed mode. When a combustion stability is lowered to a predetermined level after the control mode is changed from the high-speed mode to the low-speed mode, it is determined that the intake valve lift controller has a malfunction in which the intake valve lift controller is stuck in the high-speed mode.
