How to maintain the engine in summer? How to maintain a car engine in summer?

1. Clean the water tank regularly. Rust and scale can limit the flow of coolant in the cooling system, reduce heat dissipation, and cause engine overheating or even engine damage. Therefore, it is necessary to clean the tank regularly to remove rust and scale from it.

2. Replace the oil and filter element regularly. The oil quality of any quality grade of lubricating oil will change during use, in order to avoid the occurrence of failure, the oil should be changed regularly in combination with the use conditions, and the oil volume should be moderate, generally the upper limit of the oil scale is better).

3. Keep the crankcase well ventilated. Most gasoline engines are now equipped with PCV valve crankcase forced ventilation devices), but contaminants from the blow-by gas can be deposited around the PCV valve and may clog the valve. Therefore, contaminants must be removed regularly from around the PCV valve.

4. Use lubricating oil of appropriate quality grade. For gasoline engines, SD-SF gasoline engine oil should be selected according to the additional devices and conditions of use of the intake and exhaust system; Diesel engines should be selected according to the mechanical load of CB-CD grade diesel engine oil, and the selection standard shall not be lower than the requirements specified by the manufacturer.

5. Clean the fuel system regularly. Regular cleaning of the fuel system to control the formation of carbon deposits keeps the engine in top condition.

6. Maintain three filters. The three filters are air filters, oil filters, and gasoline filters. The three filters filter the air, oil and gasoline on the automobile engine, so as to protect the engine and improve the working efficiency of the engine.

7. Clean the crankcase regularly. During the operation of the engine, the oxides of high-pressure unburned gas, acid, moisture, sulfur and nitrogen in the combustion chamber enter the crankcase through the gap between the piston ring and the cylinder wall, and mix with the metal powder produced by the wear of the parts to form sludge. Therefore, the crankcase should be cleaned regularly to keep the inside of the engine clean.

Regular maintenance, my car 5000 kilometers to change the oil, in the dusty environment to use the air filter, usually pay attention to the water temperature, the water temperature is too high to the engine damage is great, there is to keep the surface of the water tank clean, (affecting the heat dissipation of the water tank).

Summers are hot and humid, with a lot of rain and humidity, so it's best to clean the air intake net to remove impurities. In addition, if the temperature difference between winter and summer is much different, you can change the lubricating oil that is more resistant to low temperatures. The 5W-40 of the magnetic protection is not bad, it can be used all year round, it can cover a relatively large temperature difference, and there is no pressure on hot and cold starts.

For others, if it is not time for maintenance, there is no need to replace them.

Regularly change the oil that meets the requirements of the original car.

Check if antifreeze is missing or needs to be replaced. Adjust in a timely manner. Because antifreeze also has an anti-boiling function.

Check whether the condenser is dirty, and clean it in time if it is dirty, so as to affect the refrigeration effect.

Clean the evaporation box and air duct of the air conditioner, sterilize and deodorize the cab, and ensure the freshness of the air environment in the cab.

Replace the cabin air filter.

Seal the paint to ensure that the paint is not affected under the scorching sun.

It is best to park in a sheltered place and avoid exposure to the sun.

Check the tire pressure regularly and adjust it.

Hope it helps!!

I don't need special care, and I never take care of it because of the change of seasons.

How to maintain a car engine in summer?

To maintain the normal operation of the engine cooling system, the level and quality of the coolant should be checked regularly to ensure proper circulation.

The temperature is high in summer, and the engine is more likely to overheat, so also pay attention to check the radiator for dust or blockage to avoid affecting the heat dissipation effect.

Pay attention to the cleanliness of the engine.

In the hot and rainy summer, dust and debris on the road can easily accumulate around the engine, which affects the heat dissipation effect and air entry and exit, and even causes fires. Therefore, it is very important to clean the engine regularly, and you can choose a professional car detailing shop to do it. In addition, it is also necessary to regularly check the appearance of the engine for cracks or leaks, and replace the aging seals in time.

Pay attention to the way the car starts and driving habits.

In summer, the temperature is high, and it is easy to start without motivation before starting, but it is necessary to avoid long-term idling. Prolonged idle operation can cause the engine oil temperature to become too high, increasing engine wear and fuel consumption. Drive as soon as possible after starting to allow the engine to be fully running and cooling.

During driving, avoid hard acceleration and hard braking to reduce stress and wear on the engine.

Prevent engine overheating.

High temperature weather, overloaded operation of air conditioners, and failure of heat dissipation components will inevitably affect the heat dissipation of the engine. In particular, the air conditioner emits a lot of heat when it runs for a long time, which worsens the heat dissipation condition of the cooling system.

If components such as fans and radiators fail, it will also affect the heat dissipation of the engine, causing the water temperature of the tank to rise sharply for a short period of time until it boils. Therefore, Xiaoyi recommends that the car owner always check the condition of the water tank to ensure the best cooling water.

Prevents engine "pharyngitis".

Check the "throat" of the engine - the air filter. Before the air enters the cylinder, it must be finely filtered by the air filter before it can enter the cylinder. The air filter is the patron saint of the engine, and the quality of the air filter is related to the life of the engine.

If a dirty air filter is used in the car, the engine will be under-intake, so that the fuel combustion is incomplete, resulting in unstable engine work, power decrease, and fuel consumption increases. Therefore, it is essential for the car to keep the air filter clean.

Change the engine oil in time, once the oil is blackened, thinned and sandy, it should be stopped immediately, and if you do not change the oil for a long time or use deteriorated oil, it will not only fail to lubricate but also damage the engine. When changing the engine oil, it is recommended to replace the chain lifting filter at the same time, in order to prevent the dirt in the old filter from destroying the quality of the new engine oil, otherwise the new engine oil will be replaced in vain.

The engine is a machine that converts chemical energy into mechanical energy, and its conversion process is actually the process of work cycle, simply put, it is through the combustion of fuel in the cylinder, generating kinetic energy, driving the reciprocating movement of the piston in the engine cylinder, thereby driving the connecting rod on the piston and the crank connected to the connecting rod, making reciprocating circular motion around the center of the crankshaft, and outputting power.

1. Body: It is the assembly base of each part of the engine. It includes the cylinder head, cylinder block, lower crankcase (oil pan). The cylinder head and the inner wall of the cylinder block together form part of the combustion chamber. Many parts of the body are part of other systems.

2. Crank connecting rod mechanism: It is a mechanism used by the engine to generate and transmit power, through which the linear reciprocating motion of the piston is transformed into the rotary motion of the crankshaft and output power. It includes pistons, piston pins, connecting rods, crankshafts with flywheels, and cylinder blocks, among others.

4. Fuel supply system: The fuel supply system of gasoline engine includes gasoline tank, gasoline pump, gasoline filter, air filter, carburetor, intake pipe, exhaust pipe, exhaust muffler, etc. Its function is to mix gasoline and air into a suitable combustible mixture and supply it to the cylinder for combustion, and exhaust the exhaust gases generated by combustion out of the engine.

5. Cooling system: mainly including water pump, radiator, phoenix fan, water distribution pipe and cylinder block and water jacket in the cylinder head. Its function is to dissipate the heat of high-heat parts into the atmosphere to ensure the normal operation of the engine.

6. Lubrication system: including oil pump, pressure limiting valve, lubricating oil channel, filter collector, oil filter and oil radiator, etc. Its function is to supply lubricating oil to the friction parts to reduce the friction resistance between them, reduce the wear of the parts, and partially cool the friction parts and clean the friction surface.

7. Starting system: including the starting mechanism of the engine and its auxiliary devices.

<> "How to maintain the engine.

The maintenance manual reminds you to change the engine oil after driving 7500 kilometers, but there is also a reminder that if the vehicle is often driven in dusty areas, often short-distance driving, and often driving in congested areas, the number of oil changes and hail should be increased. Many people only look at 7500 kilometers of maintenance and do not notice the factors behind it. If the vehicle is often congested in the city or often drives at a total speed, it is recommended to change the engine oil at 5000-6000 kilometers regardless of the quality; If the vehicle is often operated for long distances or on the national highway for a long time, it can be maintained according to 7,500 kilometers.

There are many other factors that make it possible to maintain the vehicle in advance, so you can't just use a good oil, especially if you wantonly extend the oil replacement cycle, which is more than worth the loss.

The contents of the maintenance manual are subject to change without notice. The implication is to refer to the latest maintenance manual. For vehicles produced in different batches of the same car, the content of the maintenance manual is updated, and the oil is always changed according to the requirements of the latest maintenance manual.

For example, many cars used to change the engine oil for 10,000 kilometers, then 7,500 kilometers for replacement, and now for 5,000 kilometers for replacement. The latest maintenance manual is carried out, so it is 5000 km to change the oil. After many imported cars arrive in China, they must pay attention to the cleaning of the oil circuit, because the quality and composition of domestic fuel have changed greatly, and they should be cleaned with suitable detergents to reduce the ash content of combustion.

A good engine oil can delay the burning of engine oil, but if the replacement interval is extended, it will not play a really good role.

The above is the root cause of whether the turbine engine causes the oil to burn, and the conclusion is that there is no necessary connection. If the vehicle is using 30 engine oil, be sure not to use 40 engine oil after burning the oil, because increasing the viscosity of the engine oil at will will produce many other subsequent unpredictable problems, especially in recent years, the engine oil requirements are extremely strict, casually improve the viscosity of the engine oil, may cause the cylinder, and the impact on the turbocharger is also great, so regardless of whether the oil is burned or not, choose the right oil sticky bend to let the sail, do not arbitrarily increase the viscosity. If you want to solve the problem of burning engine oil caused by piston ring blockage and stagnation, use the repair agent of PNF technology to repair the burning oil and remove carbon at the same time.

Engine oil is the blood of all vehicles, which shows how important oil is. In general, gasoline engines are based on the exhaust pipe system and the conditions of use to select the appropriate oil. The standard of our oil selection is usually not lower than the manufacturer's specified value.

When the outdoor ambient temperature is lower, we can choose some engine oil with small viscosity, and vice versa.

There are many big brands of engine oils on the market, and these oils have good performance in terms of wear resistance, and the stronger the wear resistance, the smaller the wear coefficient of the engine itself, which can extend the overall life of the engine. And this kind of engine oil can not only reduce the phenomenon of engine carbon deposition and oil sludge, but also reduce the impurities of the oil pipe and the wear on the engine surface. However, car owners must pay attention to the fact that while regularly cleaning the engine water tank to remove rust and scale, we must also clean the fuel system to control carbon deposition and ensure that the engine can be maintained in the best operating condition.

The second is the engine's water tank, the existence of the water tank is to keep the engine "cool" at all times, otherwise the engine will cause irreparable damage to the engine once it overheats! Therefore, it is necessary to ensure that the coolant in the water tank is kept at a normal level, and to choose the best one, especially in winter, you should also choose the appropriate coolant according to the ambient temperature. In the normal maintenance program of the car, the engine antifreeze needs to be replaced every year of driving.

In cold winter weather or in some environments with low temperatures, the first thing we need to do is to warm up the engine. Only when the engine is started at normal temperature will it be kept in the best operating condition, so that it will not cause unnecessary damage to the engine.

Both the machine filter and the air filter play a filtration role, but the difference between the two is that the machine filter is used to filter the oil, while the air filter filters the air inside the engine. The engine filter filters out all kinds of debris generated by the engine during operation, including metal debris, to ensure that the oil is always clean. The air filtration is to filter out the dust and fine particles in the air to prevent this kind of debris from causing secondary wear to the engine!

In the following three cases, the damage to the engine is the most severe.

Wash the engine with water. This situation is false to take care of the engine, but the real situation is to harm the engine. There will definitely be some aging wires in the engine, as well as fuse boxes, etc., when they encounter clean water, they will smoke and burn out the aging wires, and if it is serious, it will cause the entire engine to fail.

Therefore, it is recommended that you do not wash the engine with water.

The car is not used for a long time. Now the car is also very popular in the countryside, many families have bought a car, but in the summer and autumn are outside the work, only in the winter to go home to drive, so that the car is idle at home for half a year, in fact, this is also a kind of the biggest damage to the engine. Because the engine needs long-term activity, so as to ensure that it works and runs better, if you throw it for half a year, drive it for half a year, it will cause serious damage to the engine.

Soak in water for a long time. Many times it rains because there is no garage at home, especially in some rainy cities in the south, many private cars are left in the rain for a long time, which is very harmful to the engine.
