1, sensor failure. Sensor is a kind of detection device that can sense the measured information, and can convert the sensed information into electrical signals or other required forms of information output according to certain rules to meet the requirements of information transmission, processing, storage, display, recording and control.
2. Carbon deposition. Carbon deposit is the carbon deposit of the engine. When the engine is working, unsaturated olefins and gums in the fuel produce combustion products at high temperature. Carbon deposition in EDM should be avoided as much as possible, especially in precision die processing. As long as it is an internal combustion engine, it will produce carbon deposit.
