Background

At present, most of engines of manned large buses are in rear-mounted type, and a driver cannot know the safety state of the rear part in the driving process. When the abnormality is found, the accident is already in the sprouting period, and great potential safety hazards are generated to vehicles and personnel.

The temperature of the outer shell is the normal temperature of the original vehicle design when the engine runs, and the heat temperature of the grade is enough to ignite some inflammable substances. Besides metal materials, plastic and rubber products and the like are matched with the engine, and the spare parts have a much lower burning point compared with metal. The plastic with the best performance, namely ABS synthetic resin, has low thermal deformation temperature, is combustible and has poor weather resistance, and the melting temperature is 217-237 ℃. Rubber with an oxygen index of 18% -20% and a thermal decomposition temperature of 200-500 ℃; rubbers with an oxygen index of 28% to 45% generally start to decompose at 200 degrees; the silicone rubber began to decompose at 350 degrees. According to the detection method of the national standard GBT267, the combustion temperature of common medium and heavy lubricating oil is above 200 ℃, but is lower than the temperature of an engine shell. Therefore, the lubricant oil inside the engine leaks to the outside to form oil stain together with dust, and the lubricant oil is attached to the machine shell where the smoke and the temperature rise are most easily generated.

Whereas the safety of the prior art engines cannot be monitored.
