Is the life of a turbocharger low How long is the life of a turbocharger?

Pay attention to maintenance, it's good Isn't the car also lifespan?

1.First of all, let me explain the turbocharged engine, in fact, the turbocharged engine is an engine that relies on the turbocharger to increase the air intake of the engine, and the turbocharger is actually an air compressor. To be more specific, turbocharging is an air compressor driven by the exhaust gases generated by the operation of the internal combustion engine, which increases the flow of air into the internal combustion engine, thereby increasing the power and torque of the engine and making the car more powerful.

Volkswagen is currently popularizing turbocharged engines. In fact, after so many years of development, turbocharging has been very mature, as long as it is properly maintained, the turbo can be the same as the engine life. In other words, the turbine can be used until the engine is scrapped.

2.Regarding the A4L and BMW 325, it can only be said that each has its own advantages. In terms of handling, the A4L can't compare to the 325.

A4L is a front-wheel drive car, and the domestic A4L has been lengthened, and the sports cells have been very diluted, and they are more inclined to business. Only the FSI Sport version of the A4L series can be compared with the 325 control. And the 325 has always been the benchmark for sports, 50:

With a front and rear ratio of 50, BMW is proud of its naturally aspirated magnesium-aluminum engine. But in terms of cost performance, A4L obviously has the upper hand 325 The rear space is average, and it is not the same grade as A4L. And the current price is 45W, and it will be remodeled next year.

Therefore, if you pursue youth, personality, and have requirements for control, 325 must be a better choice; , low-key, pragmatic (the cost performance A4L is much higher than 325), if you usually have certain business needs, A4L is undoubtedly the best choice.

The technology of the early turbocharged engine is immature, and the life span is indeed not as good as that of the naturally aspirated engine, and it has to be replaced at most 8-100,000 kilometers.

Now the turbocharged engine technology is very mature, and the life of most turbocharged engines is about 250,000 kilometers, and many can reach more than 300,000 kilometers. For example, the design life of the Citroen engine is about 240,000 kilometers in 10 years, and the design life of the general engine is about 250,000 kilometers.

The main function of turbocharging is to increase the air intake of the engine, thereby increasing the power and torque of the engine and making the car more powerful. When an engine is equipped with a turbocharger, its maximum power can be increased by 40% or more compared to without a turbocharger. This means that the same engine can produce more power after being pressurized.

Take our most common turbocharged engine, for example, after supercharging, the power can reach the level of the engine, but the fuel consumption is not much higher than the engine, on another level is to improve fuel economy and reduce exhaust emissions.

Turbo life is generally about 250,000 km:

1. The full name of turbocharger is exhaust gas turbocharger, which compresses low-temperature and low-pressure gas into low-temperature and high-pressure gas, increases the air intake of the engine, and achieves the purpose of increasing the engine power with multiple fuel injections;

2. The supercharger itself is a low-temperature component, but the power of the supercharger is higher than that of the engine exhaust gas of high temperature and high pressure, and the exhaust gas temperature is as high as 900C1000C;

3. In addition, under the full load of the engine, the speed of the turbine is as high as 180,000 200,000 rpm, so the working environment of the supercharger is very harsh and the speed is high, which has a direct impact on the life of the supercharger;

4. Due to the high temperature and high speed, the turbine material of the supercharger is required to be high, and the bearing needs to be lubricated efficiently and stably, and the requirements for oil, bearing and oil seal are very high;

5. Therefore, when the early supercharger is used for 8.1 million kilometers, or even earlier, there will be oil leakage before and after the supercharger, which will seriously block the catalytic converter, resulting in acceleration difficulties, with the progress of technology, the supercharger has gradually matured, such as the current supercharger life has been able to persist to about 250,000 kilometers.

The life of the early products is slightly shorter than that of the engine part, generally 8 100,000 km! At present, turbo technology is very mature, and the life of turbocharged engines can be maintained at about 250,000 kilometers. For example, the design life of Citroen is about 240,000 kilometers in 10 years, and the design life of General is about 250,000 kilometers.

Therefore, when the early supercharger is used for 8 100,000 kilometers, or even earlier, there will be oil leakage in the oil seals before and after the supercharger, which will seriously block the catalytic converter and cause acceleration difficulties; With the progress of technology, the supercharger has gradually matured, such as the current supercharger life has been able to last to about 250,000 kilometers.

Hello The life of the early products of turbocharged engines is slightly shorter than the life of the engine part, generally 8 100,000 km! At present, the turbo technology is very mature, and the life of the turbocharged engine can be maintained at about 250,000 kilometers.

With proper maintenance, a modern turbocharged engine with a service life of 50-600,000 kilometers is basically not a problem.

With the progress of engine design concepts and materials, the life of modern turbocharged engines has been greatly extended compared with before, from the perspective of actual service life, it is often seen that more than ten years ago modern turbocharged cars are still running on the road, and from the actual mileage, hundreds of thousands of kilometers of turbocharged engines are still in service on the road.

The current supercharger life has been able to last up to about 250,000 kilometers. Methods to extend the service life of automobile turbocharger: 1. Due to the high temperature of the turbocharger in the process of use, and its structure is relatively special, there are special requirements in the selection of engine oil.

The engine oil used in the maintenance of ordinary gasoline engine models cannot meet the requirements of turbo cleaning and pressure models. Therefore, in the maintenance process, it is necessary to use turbocharged vehicle oil;

2. After the engine is on fire, especially in winter, it should be allowed to idle for a period of time, so that the lubricating oil can fully lubricate the bearing before the supercharger rotor is running at high speed. Do not slam the throttle after starting to prevent damage to the supercharger oil seal. After the engine is under heavy load and runs for a long time, it should idle for 3 5min before turning off the engine, so that the speed of the supercharger rotor can be reduced before turning off the engine;

3. Since in many cases, the turbocharging system of the "T" car does not play much role when driving on urban roads, and long-term traffic jams may produce carbon deposits. Too much carbon deposition will not only affect the engine work, but also easily endanger the turbocharging system. Therefore, it is recommended to remove carbon deposits from the vehicle during maintenance during the 20,000 to 30,000 km period.

At present, the models on the market are generally divided into naturally aspirated and turbocharged models. I believe that many car owners have an understanding of the difference between these two models. Many people believe that naturally aspirated engines last longer than turbocharged engines, so they still only use naturally aspirated engines.

How long do turbo engines last? Does turbocharging shorten the life of an engine?

Turbocharging is actually a method of turning natural gas air into compressed gas air in order to increase the air intake of the engine and increase the power and torque of the engine. On the same car, the maximum power before and after installing a turbocharger can vary by 40% or more, so more and more people now prefer cars with turbochargers.

However, that doesn't mean the turbocharger is perfect. On the contrary, when a supercharger is installed in a car, the temperature and pressure values generated by the engine will be greatly increased, so the loss is much greater than that of a naturally aspirated engine, which will shorten the service life of the engine to a certain extent, and will also have a negative impact on the mechanical properties and lubrication properties of the engine. As a result, most early turbocharged engines have a service life of less than 100,000 km.

But it's not entirely inevitable. Now the technology is relatively mature, which can be alleviated by many other means, which can extend the engine life to more than 100,000 kilometers.

First of all, engine oil is the blood of the engine, which plays a role in heat dissipation and lubrication during the operation of the engine. As a result, the oil requirements for current turbocharging technology are relatively high. If you use low-quality engine oil, it will damage the turbine spindle and affect the use.

Therefore, most manufacturers will stipulate that the original factory recommends high-quality engine oil with high temperature resistance and oxidation resistance to prevent this phenomenon.

Secondly, the technology of using turbochargers in automobile engines is generally higher because of their poor working environment. Therefore, we should develop good driving habits when driving, prevent more damage to the engine, and try to give the engine a buffer time after starting, so that the heat generated by the engine can be dissipated in time.

Finally, the regular maintenance of the automobile engine and the cleaning of engine carbon deposits are the most important tasks in the later stage of use. The maintenance of the car will directly affect the service life of the car. In addition, because there is no way to clean the fuel injector of direct injection technology, it is very important to add an appropriate amount of fuel to sell Tongbao, and everyone should pay attention to it.

1. The life of the turbocharged engine is not short, and the life of the normal engine is the same, but the turbocharger in the engine has to be replaced frequently, and the life of the turbocharger is relatively short;

2. The advantage of turbocharging is obvious, without increasing the engine displacement, the power and torque can be greatly increased, and the maximum power output can be increased by about 40, such as 1 8t car about 2 3 liters displacement car has the same power. In addition, the use of supercharging technology in the engine can improve fuel economy and reduce exhaust emissions;

3. Of course, after the engine adopts exhaust gas turbocharging technology, the maximum burst pressure and average temperature generated by operation will be greatly increased, which will affect the mechanical properties and lubrication properties of the engine. This is the main reason why pressurization technology has not been widely used at present.

The turbocharged engine technology is relatively mature, and the service life can be basically maintained at about 50-600,000 kilometers.

Turbocharged engine refers to an engine equipped with a turbocharger, then the turbocharger is actually an air compressor that increases the air intake by compressing air, and it uses the inertial impulse of the exhaust gases discharged by the engine to push the turbine in the turbine chamber. The turbine drives the coaxial impeller, which pressurizes the air sent by the air filter duct to pressurize it into the cylinder.

The selection of fuel and lubricating oil must be in line with the brand specified by the car, and it is forbidden to use low-grade fuel, otherwise the engine will detogate when working, causing a strong impact on the parts, increasing the additional load of the parts, thereby accelerating the wear of the parts.

Service life

When the engine speed increases, the exhaust gas discharge speed and the turbine speed also increase synchronously, the impeller compresses more air into the cylinder, and the pressure and density of the air increase can burn more fuel.

Technically speaking, the life of the naturally aspirated engine is indeed longer than that of the vortex supercharged engine, and the turbocharger has been popularized in many types of cars, which makes up for the congenital shortcomings of some naturally aspirated engines, so that the engine can increase the output power by more than 30% without changing the displacement.

The turbo life is generally around 250,000 km.

The full name of turbocharger is exhaust gas turbocharger, which compresses ultra-low temperature and low pressure exhaust gas into ultra-low temperature and high pressure exhaust gas, increases the air intake of the automobile engine, and realizes the purpose of increasing the engine output power with multiple fuel injection.

The service life of the supercharger and the automobile engine is greatly affected by maintenance, especially the supercharger. Turbocharging technology car series on the loss of automobile oil and lubrication requirements are very high, it is recommended that everyone should replace the lubricating oil within the maintenance mileage required by the manufacturer, and as far as possible to choose the original recommended automobile oil.

The high power and low fuel consumption of the turbine engine are achieved by its meticulous design and production process, which also determines its harsh operating environment. Therefore, we need to ensure the cleanliness of the working environment of the automobile engine with the bush at all times, and at the same time change the engine oil regularly, we must also regularly clean or replace the air filter to avoid dust and other debris from entering the high-speed supercharger wind wheel.

Here's how to extend the life of your turbocharger:

1. Regularly clean and change the air filter, when the air filter accumulates a lot of impurities, it will enter the compressed air impeller, which will lead to the instability of the vehicle speed and aggravate the wear rate of the seal.

2. Change the engine oil regularly, turbocharging has a high demand for engine oil, which needs to be replaced regularly. If it is not replaced in time, which causes oil deterioration, it is easy to lead to a decrease in the lubrication effect of the oil, resulting in damage to the supercharger bearing without better lubrication, and even causing the turbocharger to be scrapped early.

3. Because the turbocharged rotor bearing has high precision, no matter during installation or maintenance, there are high requirements for the working environment, so when the turbocharger fails or is damaged, it is necessary to go to the professional maintenance plant for maintenance in time, not just find a maintenance shop to deal with.
