Summer mobile fuel truck engine to go high temperature how to do
Season comes, the high temperature phenomenon of the engine of the mobile refueling vehicle is more common. There are many reasons, mainly divided into two types: First, there is coolant, and second, there is no coolant; these two different situations require different measures to deal with. Here are some emergency methods for the high temperature phenomenon of several mobile refuelling vehicle engines.
1, the engine overheating cooling system after load overload cycle is normal
After the tank truck runs under overload, the engine water temperature is close to the boiling temperature. At this time, although the engine is overheated, the cooling system can still circulate normally. First of all, keep the engine running at idle speed and prohibit flameout; use cold water to cool the surface of the radiator. In the state where the temperature drops to about 50 degrees, a thick towel soaked in water is used to unscrew the lid of the tank. Attention should be paid to avoiding the lid of the tank to prevent water spray from being burned. Finally, check whether the dipstick scale is within the normal range.
2, the engine cooling system does not have water dry state
The "dry burning" of tanker engines, that is, the operation without cooling water, is a very serious accident. At this time, cooling with any cooling water radiator is basically ineffective, and the engine can't run without heat. First of all, under the condition of the vehicle, the oil filling port should be opened and the oil should be quickly filled. This is because under the condition of complete lack of water, the engine oil will evaporate with high temperature and must be quickly replenished.
The next step is very important. After adding the lubricating oil, it must be turned off. Take any measures to turn off the engine and cut off the oil. At the same time, start the engine and run the engine passively. Sustained 10 seconds of operation, paused at intervals of 5 seconds to maintain this frequency. It is better to damage a starter, and also to keep the engine to a maximum extent to avoid serious accidents such as sticking cylinders and pulling cylinders.
Under the state of “dry burning†of the engine, it is impossible to reduce the temperature by adding cooling water, which may cause accidents such as alternating hot and cold, engine block bursts, and so on.
3, the engine temperature is too high cooling system cycle failure
There are many reasons for this type of failure, such as thermostats, cooling silicone oil fans, fan belts, and other damage caused by the cooling system does not work. First of all, we must keep the engine on the road, and it is strictly prohibited to turn off the fire; cooling the surface of the radiator with cold water is accelerated. Usually, in this kind of situation, the circulating water temperature drop is limited. Under the engine temperature of 80 degrees, intermittent flameout is taken, the flame switch is turned off or the sensor of the electronic fuel injection system is unplugged, the engine is driven by the starter, and the operation period is 10-15 seconds. , Passive operation to cool down, before the refueling car engine completely cools, remember that it is strictly prohibited at all times to open the tank lid. Finally, check whether the dipstick scale is within the normal range.
When the engine of the refueling vehicle is overheated, it is necessary to make a decisive judgment and deal with it quickly. Taking into account the above three points, the XCMG Chu Sheng tanker manufacturer will make a summary for each user:
1, to determine whether there is cooling water, lack of water or completely no water
2. It is not possible to turn off the flame immediately, except that it is completely dry without water.
3, water radiator, do not open the tank cover
4, completely lack of water should be treated separately
