What are the disadvantages of not installing a thermostat in your car's water tank?
The thermostat is one of the indispensable parts of the cooling system of the car, although the engine can work without a thermostat, but the engine water temperature will be low, low water temperature has a great impact on the engine, excessive heat loss will lead to increased energy consumption of the engine, the low temperature of the water will also lead to an increase in the coefficient of friction, friction increases will result in increased wear and tear of parts.
Low temperatures can also have a significant impact on emissions, the impact of tailpipe emissions do not meet the standards, low temperatures can also lead to warm air in the car is not hot, affecting comfort, thermostat between the engine's water pipes and the radiator (radiator), when the temperature is low, the thermostat shuts off the coolant and circulates it only in a small area of the engine.
The purpose is to allow the engine to warm up quickly and enter into normal operation, when the coolant temperature rises in order to prevent the temperature from getting too high, the thermostat opens the large circulation, the coolant enters the tank to dissipate the heat, and the cooled coolant enters the engine to cool the engine, and is continuously circulated under the drive of the water pump. If you don't install a thermostat, the engine needs to work within a certain temperature range, and too high a temperature will cause frequent detonation and reduce engine power.
Heavy lubricant can not form a lubricant film, resulting in increased wear and tear of the engine, and even deformation of parts due to high-temperature expansion, so the engine has a cooling system, high-temperature coolant through the pipeline to the front of the radiator to cool down, so as to ensure that the engine will not overheat. However, the radiator has a lot of power to dissipate heat, and if the coolant keeps circulating in the radiator, the engine temperature will soon be too low.
At this point, a large amount of heat that could be used to do work is absorbed by the engine and transported by the coolant to the radiator, dissipating it and leading to increased fuel consumption. Gasoline does not atomize well at low temperatures, and the engine is more likely to accumulate carbon, and when the engine temperature rises to 80 ° C to 90 ° C, after a period of time, you will know if there is water vapor coming out of the water, or the depth of the water becomes shallower or shallower, and it can not be completely discharged in this way.
The reason is that the sealing ring of the cylinder (water blocking ring) is damaged or shrunk due to high water temperature, if the water blocking ring is broken, the coolant will run into the oil and our oil will increase, we can pull out the dipstick to see if there is an increase or open the oil cap to see if there is any water droplets or water vapor inside the cap.
Another way is to check the exhaust pipe under the engine (where the exhaust gases are expelled) a few minutes after we start the vehicle, if there are droplets of water dripping down, it means that the engine coolant has gotten into the oil, and the only way to do that is to overhaul it and disassemble the engine.
If you remove the thermostat and don't use it, the engine coolant will always be in high circulation, the water temperature will rise slowly, the engine water temperature will not reach the optimal working temperature, if the coolant temperature is relatively low, the amount of oil sprayed will also be larger, the fuel consumption will be relatively high, and then the water temperature will rise slowly, even if you want to blow warm air in the winter, it won't be too warm.
The disadvantages of not installing a thermostat on the engine, the engine cooling cycle has been in a large cycle of large cooling mode, the engine heating is very slow, the engine for a long time in the warming state, the engine is not in the best working temperature, the engine fuel consumption will increase.
The engine has been working at low temperatures for a long time, and the fuel mixture injected is not sufficiently combusted, which will lead to the blockage of the three-way catalytic converter, and the prolonged insufficient combustion of the mixture will lead to an increase in the cylinder carbon deposits, and the engine cooling cycle has always been in the big cycle, and the engine has always been in the warming state in the winter when you use the car.
The temperature of the vehicle heater system is too low to turn on the warm air, and the wind blowing out is cool, which seriously affects the driving comfort. Whether the engine temperature is too high or too low, it can cause a lot of damage to the engine.
When the engine water temperature is too high, the cooling system should be carefully checked to see if there is poor heat dissipation, thermostat damage, excessive tank scale and other reasons, if the resulting water temperature is too high, do not easily disassemble or adjust the coolant temperature regulator, to maintain the normal operating temperature of the engine, you can make the engine has a good power and economy.
