Vehicles in the evening, the occasional attack of spontaneous combustion, some are special causes caused by the moment, but most of the vehicle is a long time to pile down the security risk burst formed. So, those parts on the bus are prone to spontaneous combustion? Bus wiring harness and engine wiring harness is the main point of spontaneous combustion parts. According to the usual encountered some conditions, the bus is prone to spontaneous combustion of the parts are mainly the following four local:
1. engine: engine oil, fuel due to leakage around the engine constitutes a lot of oil sludge, due to the vehicle engine exhaust system temperature is very high, if you encounter special conditions will lead to oil sludge burning; otherwise, the engine's high-pressure oil pipe is also prone to fuel leakage of the local, if the oil pipe leakage constitutes a spray of oil mist, and the engine exhaust system happens to be a source of heat, but also very easy to attack spontaneous combustion! Phenomenon.
2. Wiring harness. In accordance with the relevant norms, the bus wiring harness is necessary to use the car special flame retardant wiring harness, and its normal service life of 8-10 years. However, due to the market competition, especially in the public transportation bidding process of vicious cheap competition, the cost of price pressure resulting in a number of public transportation wiring harness did not use the relevant norms and regulations of the flame-retardant materials, so that in the wiring harness presents each other pressure line and other conditions, due to the rise in the temperature of the wiring harness can be triggered by spontaneous combustion of the wiring harness. There are also some harnesses due to the use of long life, aging phenomenon, but also prone to spontaneous combustion.
3. Wire harness fuse. In some of the buses we usually see spontaneous combustion incident, there are many vehicles are due to improper repair. Among the many conditions is the harness fuse is not used qualified fuse. For example, the harness fuse itself is rated at 10 amps, but after the fuse is blown, there is no complete troubleshooting, in order to prevent the fuse from being blown again, it will replace the fuse with a larger rated current, resulting in the wiring harness in the current is too large, too much heat can not be blocked in time to stop the power supply, and then triggered by spontaneous combustion of the bus wiring harness.
4. Oil supply system. The fuel supply system of the bus is very easy to present the fuel leakage of the local, once the fuel leakage, in the high temperature condition, it will have spontaneous combustion.
The above four local, is relatively easy to attack spontaneous combustion parts of the bus, so these parts are also probably the driver brother usually especially in the summer high temperature climate maintenance in the important point of concern. Only in this way can we cut down the safety danger of the bus.
Drivers probably do what usual maintenance?
Many drivers compare the vehicle to their own good brother, so, in addition to do a good job of regular protection and maintenance of the vehicle, the driver brother should be more for their own good brother to supply some of the usual care and attention. Tips for drivers brothers before the car in summer, must do the following:
1. usual maintenance to do three major maintenance: the first to check the engine oil pipe adjacent to the high-pressure oil supply pipe there is no oil leakage, oil seepage phenomenon, gas buses should check whether there is no leakage phenomenon, especially oil there is no oil leakage point, there is no leakage of gas pipe;
2. Secondly, check whether the electrical system is normal, such as lights, other electrical appliances in the car is not a normal operation; check the wiring harness around the engine, there is no loose lap in the engine or oil pipe, exhaust pipe is not off the pipe phenomenon, etc., to prevent spontaneous combustion of the engine and oil pipeline presents a danger.
