The diesel engine extinguishes itself during work, and the cause of the fault can be judged based on the degree of decrease in the speed at the time of the flameout and the exhaust color thereof. 1. If the engine is turned off, the diesel engine speed is gradually reduced, and there is no abnormal change in the sound and smoke color. Faults often occur in the fuel system. It is generally necessary to check if the fuel is used up and if the tank vents are clogged. If there is no such problem, check the oil line from low pressure to high pressure to see if the oil line is blocked and if there is air in the oil line; if the fuel injection pump or injector is supplied with oil. 3. If the diesel engine stalls, the speed gradually decreases, and the exhaust pipe is exposed to strong black smoke. The reasons are: 1 The diesel engine is seriously overloaded or the fuel supply advance angle is too small, and the fuel is not fully burned and discharged; 2 The air filter Or the air intake pipe is blocked and extinguished. 4. If the diesel engine stalls, the speed drops sharply, and the exhaust pipe emits black smoke. The causes of the failure are: (1) Insufficient or excessive lubricating oil, which causes poor lubrication of the crankshaft and the relative movement of the bearing surface, resulting in burning of the tiles. axis. 2 After the overhaul of the locomotive, the gap between the piston and the cylinder is too small, the temperature of the diesel engine increases, and the piston is stuck in the cylinder. 5. If the diesel engine stalls, the engine speed drops rapidly, accompanied by abnormal sound, mostly broken crankshaft or piston pin, connecting rod bolt broken or connecting rod nut off; valve spring broken, valve drop caused. High Precision Distance Sensor Laser range sensors combine the advantages of a visible red sensing beam with the increased range of a laser. The optical distance sensor devices are Class 2 lasers, support Class 1 customized. The high precision autonics distance sensor is successfully be used to connect to Arduino, Raspberry Pi, with +-1mm to 3mm high accuray, and long-range solutions (max up to 150m) for your application.

2. If the diesel engine stalls, the speed is unstable, and the exhaust pipe emits white smoke, the fault is mostly water in diesel. If it is confirmed that there is no water in the fuel, the exhaust pipe still emits white smoke and extinguishes, which is caused by the burning of the cylinder head gasket.
