Does the turbocharged engine have a short life? This requires first knowing what the turbocharged engine (Turbo) is. In general, people often say that the T is the first letter of the turbo (Turbo). For example, the common saying is 1.5T, 2.0T. and many more.
Turbocharged engine technology is popular every year. It uses the exhaust gas from the engine as the power to push the turbine in the turbine chamber (located in the exhaust passage). The turbine drives the coaxial impeller in the intake passage, and the impeller is compressed by the AIR FILTER. The fresh air from the pipe is sent to the cylinder. When the engine speed is increased, the exhaust gas discharge speed and the turbine speed are also synchronized, the degree of air compression is increased, and the intake air amount of the engine is correspondingly increased, so that the output power of the engine can be increased.
Many people have doubts, "Do you have a turbocharged engine that really has a short life?" Is the maintenance cost really high?
Many people think that the turbocharged engine is relatively short-lived, and it needs to be overhauled once every 8 to 100,000 kilometers. In fact, the life of a turbocharged engine is indeed shorter than that of a naturally aspirated engine, but it is not so delicate.
Due to the continuous advancement of technology, the life of turbocharged engines can be maintained at around 250,000 kilometers. For example, the design life of the Citroen 1.6T is about 240,000 kilometers in 10 years, and the design life of the universal 1.4T is about 250,000 kilometers.
The turbocharged engine has reached the end of its life and does not mean "end to sleep."
There are three main types of engine boosting methods: supercharged, exhaust turbocharged, and combined boost. Exhaust gas turbocharging was previously applied to diesel vehicles. Domestic cars began to be used on the Audi 200 with a displacement of 1.8 in 1998. Later, there were 1.8T (Turbocharaed, turbocharged) of the Audi A6 until the latest Passat 1 .8T.
The advantages of turbocharging are obvious. Without increasing the engine displacement, the power and torque can be greatly increased, and the maximum output power can be increased by about 40%, such as 1.8T car and 2.3L row. The amount of car power is equivalent. In addition, the engine can improve fuel economy and reduce exhaust emissions after using supercharging technology.
There is a misunderstanding here, the engine life is up, not that the engine has been used up, and the "life" here refers to the aging life of the turbine blades. After this time, the efficiency of the turbine will be worse and can continue to be used. And, if you are well maintained or used properly, the life of the turbine blades will be further extended and the engine will not be damaged.
Engine temperature is too high, life is shortened
At present, all turbocharged engines are basically made of aluminum alloy cylinders. Although the turbine starts with ultra-high-strength air compression, the temperature in the in-cylinder combustion chamber may exceed 1000 degrees, which will lead to engine life. Cause some impact. But not as serious as imagined, the engine body is still quite resistant.
As for the life of the turbocharged engine, in comparison, the life does not have a long life of natural inhalation, but it is not as squeaky as imagined. If you pay more attention to maintenance, you can develop good car habits, turbocharged models and even It can be hundreds of thousands of kilometers without major repairs.
