2012年下学期期末考试发动机电控技术复习题(国外英文资料) Automotive engine electronic control technology review questions The air intake system 1. engine intake in specific detection mode which can be divided into two kinds. 2. electronically controlled fuel injection system type according to the fuel injection which is divided into three parts. 3. car special multimeter is a digital multimeter, it has high detection precision, wide measuring range, strong anti-interference ability and high sensitivity. 4. fault diagnosis instrument can be generally divided into two categories. The 5. car is mainly used to display the voltage waveform oscilloscope actual input and output of automotivesensor electronic control system, it will change the car in any work waveform record at any time for maintenance personnel, analysis judgment fault, fault analysis but also a circuit or a sensor and actuator the. 6. the multi way intermittent jet engine, according to the relationship between the injection timing and the crank angle can be Divided into synchronous and asynchronous injection injection. 7. the optimum ignition advance angle of the initial composition, basic and modified. 8. engine performance analyzer can on engine without dismantling comprehensive performance testing, analysis and judgment in different working conditions of engine performance, can conduct a comprehensive diagnosis of various types of mechanical or electrical failure, high technical content of this instrument, all test items. The research and development of electronic control system for diesel 9. from the beginning of 1970s, has experienced two generations. 10. have certain pressure common rail diesel through to each cylinder injector, solenoid valve injector control Preparation of injection timing and injection quantity. 11. (EFI system) usually uses sequential injection mode. 12. belong to the quality of the air flow sensor is (hot film air flow sensor) 13. when the engine is running, the output voltage signal of sensor should be
