Electronic control unit of internal combustion engine

摘要: An electronic control unit (ECU), for use with an internal combustion engine, determines whether abnormal has occurred in the engine. The ECU uses a sensor signal amplifier to amplify from by changing amplification power of and A/D converter convert amplified digital (i.e., digitized signal). detector determine based on characteristic waveform signal, performs prevention prevent when is detected. controller used set amplitude determination result detector.
