摘要： A rotational position detecting apparatus for an internal combustion engine comprises a first and a second signal generator each thereof having a signal rotor rotating in synchronism with the rotation of the engine, a first and a second waveform reshaping circuit and a signal processing circuit. Engine rotational angle signals produced by the first signal generator and engine cylinder reference angular position signals and a specified cylinder angular position signal produced by the second signal generator are reshaped through the first and second waveform reshaping circuits, respectively, and both output signals from the first and second waveform reshaping circuits are supplied to the signal processing circuit. The signal processing circuit separates the reference signals and the cylinder discrimination signal from the output signals of the second waveform reshaping circuit and outputs the separated signals along with the angle signals produced by the first waveform reshaping circuit.This rotational position detecting apparatus for internal combustion engines is featured in that it is simple in construction and small in size and its operation is hardly susceptible to interference caused by radio noise.

摘要： Hall elements detects magnetic signals of a rotational member which is secured to the crank shaft or the cam shaft of an engine and converts them to an alternating electric signal. The electric signal is amplified by a differential amplifier and applied to a peak-detecting-type wave-shaping circuit which generates a rotational position signal and a control signal. A reset signal generator generates an interrupting signal in response to the control signal and is applied to a NAND circuit which is connected between the wave shaping circuit and an output circuit. When a power switch is closed, the power source voltage sometimes drops to an extremely low value for providing the rotational position detecting signal. At this moment, the reset signal generator generates the interrupting signal and closes the NAND circuit so that erroneous signal of the rotational position detecting signal is prevented.

摘要： In a hybrid vehicle equipped with an exhaust gas purifying apparatus, when a gasoline engine stops, an exhaust gas passage is closed by a pair of upstream-side and downstream-side throttle units to form an accommodation space. A pressure reduction unit reduces a pressure of the closed accommodation space where a three way catalyst is placed. The exhaust gas around the three way catalyst in the closed accommodation space does not leak into either an outside atmosphere side or into the gasoline engine side. Reducing the pressure in the closed accommodation space decreases heat conduction through the exhaust gas toward the outside. It is thereby possible to prevent the temperature drop of the three way catalyst and to keep the three way catalyst at a temperature of not less than its activation temperature for a long period of time even if the gasoline engine stops.
摘要翻译：在配备有排气净化装置的混合动力车辆中，当汽油发动机停止时，排气通道被一对上游侧下游侧节气门单元封闭，形成收容空间。减压单元降低了放置三元催化剂的封闭收纳空间的压力。在封闭的容纳空间内的三元催化剂周围的废气不会泄漏到外部气氛侧或汽油发动机侧。降低封闭的容纳空间中的压力减少了通过排气向外部的热传导。因此，即使汽油发动机停止，也可以防止三元催化剂的温度下降并使三元催化剂长时间保持在不低于其活化温度的温度。

摘要： A throttle unit placed in an exhaust gas passage controls an opening-ratio of each of first and second valve members to control a gas-flow sectional area of the exhaust gas passage. When the temperature of a three-way catalyst is low, the throttle unit introduces the exhaust gas flow into a part of an outer-periphery of the three-way catalyst. This control can rapidly increase the temperature of the three-way catalyst from an early period of starting an internal combustion engine within a short period of time. The throttle unit increases the gas-flow sectional area of the exhaust gas passage according to increasing the temperature of the three-way catalyst. When the three-way catalyst reaches its activation temperature, the throttle unit instructs the first and second valve members to fully open. This decreases a pressure loss of the exhaust gas because the exhaust gas is supplied into the entire of the three-way catalyst.
