摘要： A pressure transducer comprises a pressure sensor including a bridge connection of gauging resistors formed on a semiconductor substrate, and a power supply connected to the pressure sensor for driving it and basically acting as a constant current source. The power supply includes at least two transistors formed on the semiconductor substrate. One of the transistors provides a collector current which is less in temperature-dependency relative to that of the other transistor, and the other transistor has a collector circuit connected to the pressure sensor and provides a collector current corresponding to a sum of a substantially temperature-dependent current and a substantially temperature-independent current. A ratio of the temperature-dependent current to the temperature-independent current is adjusted by selecting operation characteristics of the two transistors such that a temperature characteristic of the collector current of the other transistor is substantially inversely proportional to a temperature characteristic of the output of the pressure sensor when it is driven with a constant voltage.

摘要： A sensor for detecting the internal pressure is provided in the cylinder to detect the combustion condition in the engine cylinder. In order to process the output of the sensor in accordance with the volume of the combustion chamber, the amount of change of combustion volume between timings of fetching the sensor outputs is multiplied by the sensor output, or the sensor output is fetched in accordance with the amount of change of combustion volume. In this way, the amount of work is detected from the sensor output. The ignition timing is subjected to feedback control in such a manner as to attain the maximum effective amount of work.

摘要： A control system employs a microcomputer, which controls the starting operation of a spark ignition type engine provided with a fuel injection system. The control system is loaded with, at least, contact information of an ignition switch for connecting an ignition device to a power supply and a starter switch for connecting a starter motor to the power supply, and an output signal of a temperature sensor for detecting the temperature of cooling water of the engine. Where the cooling water temperature is not higher than a predetermined temperature, a fuel pump which supplies pressurized fuel to an injector of the fuel injection system is started simultaneously with the closure of the ignition switch, and this fuel pump is stopped during the operation of the starter motor.
