Re Examining The High Water Temperature Of The Second Country: Talking About Those Things Of Domestic Engines

  • Autumn is coming, and the continuous high temperature in summer has not subsided. The “autumn tiger” will rage for a long time. High temperatures continue throughout the country, showing a booming trend. Even the Arctic has reached a high temperature of 30 degrees Celsius.
Engines
“Autumn tiger” wreaks havoc across the country, causing engine failure caused by high water temperatureIt’s hard for the majority of drivers.
  • Although there are air conditioners in the car now, and some drivers who are afraid of heat have installed hang ups with better cooling effect in the berth, they can’t avoid being exposed to the sun when loading and unloading goods.
  • Besides, the car is equipped with air conditioner, which makes people cool, but the car without air conditioner may not be able to withstand the continuous high temperature, but it seems that no car has been on strike because of the continuous high temperature recently.
Engines
  • This can’t help but remind me of the previous second diesel engine era. The old drivers who have driven national II diesel cars should have encountered a series of faults caused by too high water temperature. The most obvious manifestation of this failure is boiling. Boiling is commonly known as boiling. In fact, the engine does not dissipate heat and cool in time after working and heating, so that the coolant (mostly water) in the engine reaches the boiling point.
  • In this way, the expanded piston cannot maintain normal clearance with the cylinder liner, and the piston that cannot be cooled can only expand until the explosive force of the engine is not enough to push the piston to continue to move, because at this time, the piston and the cylinder liner are tightly locked together without any moving clearance.
Engines
  • If you find that the water temperature is high at this time, you can stop in time, or the engine shuts down because of locking, it’s lucky.
Engines
  • If the piston clearance of the engine is large, the high temperature is not enough to jam the expanding piston, and the driver fails to find it in time, the engine will run continuously, and the piston will face perforation. Perforation will cause the oil in the oil cooling nozzle to be burned, and the consequences of burning out the oil can be imagined. The engine needs a thorough overhaul. The cylinder liner, piston, crankshaft and connecting rod must be replaced if the cylinder block changes shape. You have to pay a small amount of shutdown cost if you don’t want to stop production.
  • the master is among the people, and the card friend came up with a local method
    Before the emergence of electric cars, in order to avoid this situation, our driver friends came up with different tricks, such as taking the thermostat or directly plugging it with wood. In this way, we can reduce the hot water entering the water pump, take the large cycle instead of the small cycle, and let the hot water discharged from the engine directly return to the water tank for cooling. This method can have a certain effect.
Engines
  • There are also some who have changed the fan, expanded the windward area, changed the water tank, and even installed one water tank. They use two water tanks for circulating cooling. Card friends use their brains to come up with many ways to deal with the high temperature.
  • looking back, the future of domestic engines can be expected
    We see the essence through the phenomenon. What we see is the immaturity of the second national engine. From design to technology, and then to matching the whole vehicle, we will always find some problems
Engines
  • When it is supplied to the vehicle factory, its adaptability is not considered. The truck is air-cooled and water-cooled as compared with the trolley. The long-term loading speed of the truck is slow, and the effect of air cooling is very small. When matching, we should consider the use of various models, what models are equipped with what engines, what road conditions are equipped with what engines, those who often run mountain roads, those who often run high-speed, those who run inside the construction site, etc.
  • developing good usage habits is the key
    In addition to the design problems of the product itself and the reasons for overload and overrun mentioned above, the driver’s operation also has a significant impact on the vehicle. In the case of heavy load (especially on long and steep slopes), the experienced master will reduce the gear in advance and store sufficient power. During oil supply, try to control the engine speed without dragging or exceeding the speed, so as to keep the engine in good working condition and sufficient power.
  • In addition, maintenance is also an indispensable lesson. The “maintenance instead of repair” advocated by us can effectively prevent faults. However, some drivers have committed “lazy cancer”. If they don’t check the car, they won’t find that the engine is short of water; If you don’t stop the car for maintenance, you won’t find water leakage in the engine, so you can’t find and eliminate hidden dangers in time to prevent faults.
  • However, fortunately, the application of the third national technology has greatly reduced the problem of high water temperature. The main solution is that when a certain temperature is reached, the engine gives an alarm, and the ECU receives the alarm signal to control the engine speed at about 1500 rpm, or it can only maintain the idle state. If there is no oil pressure due to high temperature, and then an alarm is triggered, it will stop directly. These effective methods do let truck people reduce losses to a certain extent.
Engines
  • Some people may say that there are more problems in the circuit of electric vehicles, and the accessories are more expensive. After calculation, the repair cost of one year is also a lot. What I want to say here is that the times are progressing and science and technology are developing. We can’t deny that electronic control has both advantages and disadvantages, but the advantages outweigh the disadvantages.
  • Today, when all important technologies rely on the introduction of foreign resources, we hope that domestic independent brands will be more advanced and mature. What we can solve is not only the problem of water temperature, but also the control of fuel consumption, power and emission, so that domestic engines in the truck market can have their own broad world. Of course, in recent years, domestic engines have also made great progress, and the future can be expected.
  • At the end of this article, let’s talk about some methods to solve the high temperature fault?
