According to the "City Express" report, two spontaneous auto-ignition incidents occurred on a viaduct in Hangzhou on May 15. The spontaneous combustion of these two elevated vehicles is not small, the 11 in the morning and the 10 in the afternoon. The probability of spontaneous combustion on the elevated is high, and the traffic police analyzes this way: When the weather is hot, the elevated road without shade is higher than other roads in the urban area, and the vehicle is warming up; the traffic flow on the elevated road continues to increase, and the vehicle queues and low-speed driving often occur. When the vehicle is driving at low speed, the engine heat does not dissipate. Going out, the engine overheats, if you encounter problems such as gasoline leakage, it is very easy to spontaneous combustion. The fire department said that auto spontaneous combustion started to increase after May 1 this year-a spontaneous auto ignition occurred in the urban area on May 10 and 11, respectively. There were four cases on May 13 and as of yesterday afternoon, only firefighting was dispatched. There were three spontaneous combustions of cars, except for the morning on the elevated road, at the 7:24 Tanghe Road Teachers ’Intersection and 11:36 Xinhua Road Fengqi Intersection. Circuit aging and oil leaks are the main problems of auto spontaneous combustion. Especially for a car with a long age, it is better to check the oil circuit and circuit in the near future, and do n’t forget to put a fire extinguisher in the car.
