What should I pay attention to when using a car engine in summer?

Due to the high ambient temperature, the engine is easy to overheat, and it is necessary to strengthen the inspection and maintenance of the engine cooling system, including the inspection of water tanks, thermostats, water pumps, fans and other components, and pay attention to filling cooling water in time. When the water temperature exceeds 100 °C, stop in the shade to cool down, idle the engine, and lift the hood to help dissipate heat.

The oil and filter element should be replaced regularly, and the oil quality will change during use, and the performance will deteriorate and bring various problems to the engine. When the oil passes through the pores of the filter, the solid particles and viscous matter in the oil accumulate in the filter, causing the filter to clog or the oil cannot pass through the filter, and then the filter element is burst.

In hot weather, the viscosity of the oil will also decrease, and its oxidation resistance will become weaker, causing poor lubrication, so you should also pay attention to checking and changing the oil. The temperature is high, and spontaneous combustion of the engine control line may also occur, so for the old car, it is necessary to check and maintain it frequently to see if there is a problem with the aging of the line, if the car smells of burnt smell, you need to stop and check immediately, remember to break the key as soon as possible, and find a good fire extinguisher at the same time.

In summer, due to the high outside temperature, the heat is not easy to dissipate, and the distillation temperature of oil evaporation is high, so it is more likely to produce carbon deposits in the engine, or form a gas blockage to block the oil pipeline, and in severe cases, the engine may stop running.

Due to the hot weather, high engine temperature and poor heat dissipation conditions, it is easy to produce air resistance and affect the normal driving of the vehicle. In this case, stop to cool down, remove air resistance and continue driving. Pay attention to the temperature pointer of the dashboard in the car, if the temperature is too high, check whether the engine cooling water is short of water and the cause of high temperature, and replenish the cooling water in time after consumption to keep the cooling system pipeline unblocked.

Prevent engine deflagration: The temperature is high in summer, sometimes exceeding 35, and in such a season, the probability of natural deflagration is much higher for some cars with aging components. So be prepared.

In summer, when the air expands, the air density decreases, and the amount of air in the engine is reduced, which affects the output of the engine. Tests have shown that when the outside temperature rises from 15 to 40, the power of the engine decreases by 6%-8%. Therefore, in hot weather, especially those cars with a small displacement, they often feel powerless to accelerate, and an important reason is the lack of air intake.

If the high temperature light is flashing, it is also necessary to pay attention to find the cooling channel problem, and also check whether there is too much dirt on the blades of the heat sink, whether the fan is running normally, etc. If the car runs on some muddy country roads for a long time, it will often cause such problems, so you need to blow the grille with compressed air and then rinse it with water.

In summer, the car is most prone to high temperatures, and when maintaining, you must pay attention to check whether the timing belt is damaged, and then whether the air conditioner can work normally, if there is no air conditioning, it is very uncomfortable to drive in summer.

Don't use it for too long, be sure to give him enough rest time before he can continue to use it, and it's best to stop him after driving for two hours to avoid overheating the engine and stalling in the process.

Attention should be paid to the engine temperature should not be too high, in the process of long-term use, every once in a while should stop and rest for a while, to cool down the engine. In the summer, if you open the front hood and put your hand on the engine, it will bubble instantly.

The winter temperature in most parts of our country is low and the cold season is long, which brings a lot of inconvenience to the use of machinery and vehicles. For this reason, the following are several issues that need to be paid attention to when using the engine in winter: 1. If the engine can start smoothly, it is best to use antifreeze as coolant.

The quality of the selected antifreeze must be qualified, especially the pH value and stability of the antifreeze must meet the requirements, otherwise it will corrode the waterway and water seal, causing water leakage and other failures. In addition, the freezing point of the selected antifreeze should be about 5 below the minimum temperature in the region, and its freezing point should often need to be monitored with antifreeze to prevent damage to the engine from freezing. If an emulsion thickener is found in the oil, it means that the antifreeze has leaked into the oil, because the general antifreeze is formulated with ethylene glycol and demineralized water as the main raw materials.

Second, the selection of oil including coarse lubricating oil and fuel oilThe quality grade of lubricating oil is generally selected according to the requirements of the engine manual. If you don't have it for the time being, you can change to a higher grade of lubricating oil, but you can never change to a lubricating oil that is lower than the standard used in this machine. In winter, diesel engines should choose low-grade diesel with strong volatility.

In general, the number of diesel fuel should be 5 10 lower than the ambient temperature. 3. Addition and discharge of softened water If it is difficult to start the engine, hot water should be added, and low-temperature starting fluid should be used if necessary. If cold water is added before starting, it is easy to freeze in the radiator and other places during the water addition process or when the water is not started, resulting in the failure of the circulating cooling water and even the expansion and cracking of the radiator.

Heating the water can prevent the above-mentioned freezing phenomenon; At the same time, it can increase the temperature of the engine, which is conducive to starting. However, if the temperature is not very low, adding cold water can still be started, but it must be demineralized water. Due to the addition of hard water without softening treatment in the engine cooling system, it is easy to deposit scale around the waterway of the cooling system during the heating process, and frequent addition and discharge will cause a very fast scale deposition rate, which will soon reduce the cooling effect of the engine cooling system, and even block the circulating water channel, resulting in the phenomenon of excessive engine temperature or "boiling return water".

Be careful not to use low-temperature starter fluid on this stool frequently, as it will shorten the life of the engine; Do not dry start first and then add cold softened water to avoid cracking of the cylinder head and water jacket; When the machinery is working normally, the engine temperature should be kept above 50; Do not turn off the water immediately after stopping the machine, because the temperature of the engine is still relatively high.

<> "Summer is coming, in addition to people need to prevent high temperatures, vehicles also need to be prevented, the high temperature of the vehicle is basically due to the engine when it is working, and this temperature will continue to rise with the work of the engine, in order to avoid the risk of high engine temperature, basically will take certain measures for the engine, through some good heat dissipation of the cylinder block materials, and even through external physical factors to increase cooling water. So when using the engine, how to prevent the engine water temperature from being too high?

To prevent the engine water temperature from being too high, you can start from the following aspects.

The first aspect.

Replace and add coolant according to the regulations, that is to say, the coolant at this stage is basically resistant to high temperatures, and the maximum temperature of the engine can be reduced to 105 degrees Celsius.

The second aspect.

Regularly clean the engine radiator (water tank) According to the principle of engine heat dissipation, the coolant flows into the bridge engine through the radiator, and then returns to the water tank after circulating inside the engine, so the water temperature is taken away in the process of circulation. After the coolant arrives at the radiator, it will take away a simple water temperature through the rotation of the fan installed behind the radiator, and take away a part of the water temperature through the gap between the radiator itself, so in order to have a good heat dissipation effect, it is necessary to maintain the ventilation of the radiator.

The third aspect.

When using the vehicle, avoid excessive driving, which is very normal for the vehicle, after all, from the perspective of coolant, the high temperature resistance is only temporary, and violent driving will make the parts reach a limit and produce high temperatures. Finally, for the engine to prevent high temperatures, in addition to starting from the use, the most important thing is to maintain a good condition is very important.

Hot weather is a great beauty for cars, so how to prevent heatstroke for cars in summer? Let's take a look.

Modified cars should be cautious and diligent to check the line to prevent spontaneous combustion.

Every summer, quite a few cars spontaneously combustion. According to the statistics of the traffic police department, from May to September every year is the period with the highest concentration of spontaneous combustion accidents of automobiles. Spontaneous combustion of automobiles is generally caused by damage to oil circuits, circuits and automobile modification parts, and there is no direct relationship between the old and the new, among which the aging and poor contact of the engine circuit are particularly important reasons for the spontaneous combustion of automobiles.

The reason why there are more spontaneous combustion accidents in old cars is related to the fact that many old car owners do not pay attention to maintenance.

Therefore, to avoid spontaneous combustion of automobiles, it is still necessary to focus on prevention. The continuous high temperature in summer is more likely to induce line hardening, cracking, and leakage, so that a short circuit occurs, which will affect the normal driving of the vehicle in light cases, and will lead to spontaneous combustion of the car in severe cases. This is like the engine is the heart of the car, and the wiring is the blood vessel of the car; Bad blood vessels will affect heart function and damage people's health, and bad wiring will affect engine performance and endanger driving safety.

In addition, if the goods on the vehicle are not properly placed, they will collide with each other, resulting in sparks, which can also cause spontaneous combustion of the car.

Prevent punctures, check more, find hidden dangers, and replace them in time.

In the summer, the chance of a flat tire increases, and a flat tire in a moving car can be dangerous. The ground temperature can reach more than 60 degrees Celsius in the hot summer, and despite the thick tire leather, the possibility of a puncture will still greatly increase when driving on such a road surface for a long time. Therefore, the first thing to remind is that in summer, we should try to avoid driving at high speed for a long time, because this will also cause the tire temperature to rise, which will lead to accelerated aging of the tire rubber surface, and in severe cases, it will also lead to a puncture.

In addition, if the car is driven on a hot road for a long time, the air pressure in the tire increases, and if the tire is damaged or weak, it is easy to have a puncture. Therefore, car owners should always check their tire pressure. If the tire temperature and tire pressure are found to be too high, the tire temperature and pressure should be naturally reduced, and water and inflation should not be directly splashed and deflated.

In addition, the owner should regularly clean the tires to prevent foreign objects in the tire tread grooves, and check the wear of the tires regularly. Don't forget to look at the tires when you get out of the car. If you have a nail, scratched the tread, or a bulge due to the impact of the tire, be sure to go to the repair shop as soon as possible to check for a replacement.

The thermostat cannot be removed, and it will damage the engine if it is removed.
