Some people say that the life of the turbocharger is only 100,000 kilometers, is this really the case? In fact, the life of a turbocharged engine is far more than 100,000 kilometers.
Today’s turbocharged engine has become the mainstream in the market, but there are still old drivers who have the idea that turbocharged engines cannot be bought and are easy to break, and believe that turbocharged engines only have a lifespan of 100,000 kilometers. Think about it, if the real service life is only 100,000 kilometers, for car companies like Volkswagen, the sales of turbocharged models are several million a year. If the service life is really so short, they would have been drowned by saliva. The lifespan of a turbocharged engine is indeed not as good as that of a self-priming engine, but it is by no means only 100,000 kilometers. The current turbocharged engine can basically achieve the same lifespan as the vehicle. If your car is scrapped, the engine may not be damaged.
There is a saying on the Internet that the current turbocharged engine life is about 250,000 kilometers, because Citroen’s turbocharged engine once clearly stated that the design life is 240,000 kilometers, but Citroen’s so-called “design life” refers to the engine The time for performance and components to accelerate aging, that is to say, after 240,000 kilometers, the relevant components of the turbocharged engine will experience significant performance degradation, but this does not mean that the turbocharged engine will definitely decline immediately after reaching 240,000 kilometers. It’s just that this engine may experience a certain degree of performance degradation, such as increased fuel consumption, reduced power, increased noise, and so on.
The reason why the life of the previous turbocharged engine is short is because the technology is immature, and the working temperature of the turbocharged engine is high, and the engine material process is not up to standard, resulting in frequent damage to the engine after it is out of warranty. But today’s turbocharged engine is no longer the same as it used to be.
1. In the past, the turbochargers were all large turbochargers, which usually took more than 1800 rpm to start the pressure, but now they are all small inertia turbines, which can start the pressure at a minimum of 1200 rpm. The service life of this small inertia turbocharger is also longer.
2. In the past, the turbocharged engine was cooled by a mechanical water pump, but now it is cooled by an electronic water pump. After stopping, it will continue to work for a period of time to cool the turbocharger, which can prolong the life of the turbocharger.
3. Today’s turbocharged engines are equipped with electronic pressure relief valves, which can reduce the impact of airflow on the supercharger, improve the working environment of the supercharger, and increase the life of the supercharger.
It is precisely because of the above reasons that the working life of turbochargers has increased significantly, and we must know that it is generally difficult for domestic family cars to reach the design life of a car. Older cars are miserable, so even if the vehicle is scrapped, your turbocharger may not have reached the design life, so don’t worry too much about the life of the turbocharged engine.
