How can I extend the life of my engine?

The engine is the heart of the car, and how to keep the engine young is the key to car maintenance. First of all, we should pay attention to the run-in maintenance during the service life, which is the basis for extending the service life of the engine, in addition, we should be careful of the three common diseases of the engine: 1. Engine wear.

One is the cold start (that is, the engine is shut down for more than 6 hours), which produces dry wear at the moment of starting, and the damage to the engine is the greatest. Another situation is that the engine is running at high speed, the oil is relatively thin, and the engine is in a semi-dry wear state, which is also a phenomenon that cannot be ignored. 2. The phenomenon of oil loss.

This situation is caused by the gap between the combustion chamber and the cylinder, which causes oil to enter the combustion chamber. The way to find out that the engine is losing oil is to first look at the exhaust pipe to see if there is blue smoke, put your hand to the exhaust pipe to probe it and smell your fingers for organic oil, if there is a smell, it proves that the organic oil in the engine has escaped into the combustion chamber. 3. The oil seal ring is aging.

The oil seal ring is aging, the oil is slowly leaking out, for the phenomenon of slight oil burning, a certain amount of repair agent can be added when changing the oil can be solved. If the situation is severe, the engine needs to be disassembled. In addition, it is necessary to observe and inspect the engine frequently, and eliminate the fault in time to keep the engine in good technical operation

1. Check the fastening parts frequently. Diesel engine or gasoline engine is affected by vibration impact and uneven load during use, bolts and nuts are easy to loosen, and the adjustment bolts of each part should be carefully checked to avoid damage to the parts due to loosening. Valve clearance, valve phase, fuel supply advance angle, fuel injection pressure and ignition timing should be checked and adjusted in time to ensure that the engine is always in good technical condition.

This saves fuel and extends engine life. 2. Keep the oil, water, gas and body clean. The fuel is not pure, which can make the precision fitting parts wear out, and the matching gap increases, resulting in oil leakage, oil dripping, reduced power supply pressure, larger gap, and even serious faults such as oil circuit blockage and shaft burning tile; If there is a lot of dust in the air, it will accelerate the wear of cylinder liners, pistons and piston rings; If the cooling water is not pure, the scale of the cooling system will increase, hinder the heat dissipation of the engine, the lubrication conditions will deteriorate, and the parts will be seriously worn; If the appearance of the body is not clean, the body will be corroded and the service life will be shortened.

3. Ensure that there is enough oil, water and air. If the gasoline and air are not timely or interrupted, there will be difficulties in starting, poor combustion, power decline, and the engine cannot run normally; If the engine oil is insufficient or interrupted, the engine will be poorly lubricated, the parts will be seriously worn, and even the phenomenon of tile burning will occur; If the cooling water is insufficient, the temperature of the machine will be too high, the power will decrease, the wear will be aggravated, and the service life will be reduced.

Use the engine oil well, change the oil when you get to the kilometer, and often check the amount of engine oil, brake oil, gear oil, and antifreeze.

Regular maintenance, regular reinforcement of the site, I am a car repairer, if you don't understand, you can send me a private message, hope.

Use the oil well and change it frequently.

If the car is used for a period of time, it needs to be repaired and maintained, because there will still be a little safety hazard when the car is used for a long time, and some may be more secretive and we are aware of it. When the car is driven to the repair shop, there will be professional maintenance personnel to do a comprehensive inspection of the car to prevent accidents. This allows problems to be identified earlier and then resolved.

Overloading not only affects the safety performance of the vehicle, such as braking and operation, but also leads to tire deformation, puncture, brake failure, etc. Not only that, but prolonged exposure to the engine under load can also lead to accelerated wear. Due to the use of the engine for a long time, its own performance will deteriorate, so in order to ensure that it does not bring harm or impact to the engine, it should be replaced in time.

Foreign bodies are an important factor in the service life of the tread of the tire. Starting too fast, sudden turns, emergency braking, high-speed driving in bad road conditions, frequent up and down curbs and parking tires scraping obstacles can lead to severe tire wear and tear, which reduces the life of the tires. Therefore, it is necessary to change the tire position in a timely manner, choose the appropriate tread to deal with and maintain it every day, check the tire pressure regularly, and repair and deal with the digging stones in a timely manner.

1.Pay attention to the running-in period The running-in period generally refers to the process of contact, friction and occlusion of mechanical parts in the initial operation. The performance of the engine in the future is inseparable from the homework done by the owner during the run-in period of the new car. Specification for running-in, is to extend the service life of the engine.

2.Regularly inspect the fastening parts The engine is affected by vibration, shock and uneven load during use, and the bolts and nuts are easy to loosen.

3.Keep the oil clean, water clean, gas clean and the body clean If the fuel is not pure, it will wear out the precision fitting parts, resulting in oil leakage, oil dripping and power supply.

4.Ensure sufficient oil, water and air If the gasoline and air are not timely or interrupted, there will be difficulty in starting, poor combustion, and power.

Normal driving and maintenance, without any accidents, what is the life of a car engine, this is really hard to say, this depends on the manufacturer's data, generally how many thousands of kilometers without overhaul, will not be very high and will not be very low, hundreds of thousands of kilometers for ordinary use enough!

But when it comes to how many years it can be used, this single from the perspective of use, luck, road conditions, user habits, maintenance, policy, environmental protection are related, I have watched a few programs to say that the car engine is repaired, according to the technician, there is no engine that can not be repaired, just a matter of cost, even if the cylinder block is broken, it can be repaired, so you can rest assured that it can be used for many years, until you don't let you drive, or you don't want to drive!

The human factor of driving a vehicle is directly proportional to the long life of the engine.

We all know that the vehicles produced by the current car companies are assembly line assembly, and the processing of parts is also produced under a unified standard, and the processing accuracy of each part and the error generated in the assembly process are very small, and it can also be said that they are basically the same.

The car is mechanical, no one is dead when no one operates it, and the person who operates it is alive, so the driver's personal proficiency and experience in operating the car directly affects the service life of the car. The driver's experience is accumulated for a long time, to put it bluntly, it is a kilometer by kilometer, experienced drivers in contact with the use of new cars, due to the increase in the current vehicle electronics, first of all, will carefully read the manual.

First, change the oil according to the maintenance manual kilometers, so that the internal gear lubrication of the engine is always in good condition, which is essential for the life of the engine.

Second, good driving habits, do not low-grade and large oil, let the engine run under load, you can reduce the wear of the internal gears of the engine.

The engine life of a normal vehicle is about 15 years, and if it is well maintained, it can be driven to 20 years, with more than 600,000 kilometers; If the maintenance is a little worse, the condition of the car is a little worse, about 10 years; You don't even want to drive this car; The life of the engine is related to the personal habits of the car, the working conditions, the state of the parts when they leave the factory, the protection and hail maintenance of the engine, etc.; Environmental factors: If a high-quality engine is often in a humid and congested environment, the life of the engine will be greatly reduced; Internal influencing factors, engine oil is mainly used for lubrication, cooling, sealing, cleaning, rust prevention of a variety of roles, the oil is not only to be divided into good and bad, but also to choose the label.

Now the car can generally do 500,000 kilometers without repair, the life of the engine and durability and reliability are related, first determined by the design life of the engine, and then after the search to determine the later proper maintenance, depending on the use.

In general, under normal conditions, the life of the engine is between 10-20 years. However, the service life of the engine cannot be generalized. Consider the engine brand, frequency of use, degree of maintenance, number of kilometers, vehicle condition, road conditions, etc.

However, according to the relevant policy, vehicles with a mileage of 600,000 kilometers will be scrapped, regardless of whether the engine is still in use.

Attention should be paid to the following aspects in the use of the engine:

1.Fuel must be clean. The high content of impurities in the fuel will accelerate the wear and tear of the electric fuel pump, reduce the service life of the fuel pump, and reduce the performance of the engine.

2.Choose the right fuel. There are high requirements for the quality and brand of the engine stove brigade oil dismantling, especially the EFI engine. For cars with catalytic converters and oxygen sensors, only unleaded high-grade gasoline can be used.

3.Refuel in a timely manner. The electric fuel pump of the EFI engine should meet the requirements of sufficient fuel and stable working pressure of the injection system. When the fuel in the fuel tank is insufficient, the fuel should be replenished in time to prevent the fuel pump from burning out.

4.When the ignition is turned on, do not disconnect the electrical equipment circuit. Electrical equipment mostly consists of electromagnetic coils. If the circuit is de-energized, the coil will generate instantaneous high voltage under the action of self-induction, which may cause damage to the computer or sensor.

5.Clean the fuel system and air intake system regularly. An unclean fuel system will lead to a series of failures such as oil circuit blockage, loose valve closing, poor fuel injection atomization, insufficient oil supply, and low oil supply pressure, which will directly affect the normal operation of the engine.
