Speed sensing |
摘要 |
Diesel engine speed is sensed by a thermistor which is disposed within an air inlet of the engine manifold so that the resistance of the thermistor varies in accordance with the temperature of the air within the inlet and thus in accordance with the speed of the engine. The thermistor is connected in a transistor circuit which derives, in response to the change in resistance of the thermistor, an electric signal having a frequency which varies in accordance with engine speed.
