摘要： A signal transmission system for transmitting, in particular, an ignition timing correction signal in an ignition timing control system for an internal combustion engine includes an ignitor for producing an ignition timing signal in response to an ignition signal from a distributor, and the ignition timing signal is further corrected by the ignition timing correction signal calculated in a computer based on engine operating conditions sensed by sensors. The computer includes a voltage-current converting circuit which converts the ignition timing correction signal in the form of a voltage signal into a current signal corresponding thereto and supplies the current signal to the ignitor through a signal line connecting between the computer and the ignitor. The ignitor includes a current-voltage converting circuit to convert the current signal from the computer into a voltage signal corresponding to the current signal which indicates the correction of the ignition timing.

摘要： Backward movement of a heavy motorcycle is assisted by a starter motor for cranking an engine of the motorcycle. A backward drive control system includes a pulse width modulation circuit for supplying operating current to the starter motor in a controlled manner and a device for estimating operating temperature of the starter motor based on the current supplied to the starter motor. When the estimated temperature reaches a predetermined maximum temperature, the operation of the starter motor is compulsorily stopped and prohibited for a certain period or until the starter motor is cooled down to a certain temperature level. Overheating of the starter motor is effectively prevented without using a temperature sensor for measuring the operating temperature.Moreover, chattering of the starter motor does not occur because its operation is prohibited for a certain period after the starter motor is once compulsorily stopped.

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.
