The turbocharger is actually an air compressor, which increases the air intake by compressing the air. The quality of the turbocharger affects fuel economy. So, how long is the life of the turbocharger?

The service life of turbocharger can reach more than 250000 kilometers or even longer. So even if the car is scrapped, your turbocharger may not reach its design life, so don't worry too much about the life of the turbocharged engine.

The reason for the short service life of the turbocharged engine in the past is that the technology is not mature, while the high working temperature of the turbocharged engine and the insufficient technology of the engine materials lead to frequent engine damage after warranty. But today's turbocharged engine is different.

Turbochargers used to be large turbines, often requiring more than 1800 rpm to start the pressure. Now they are small inertia turbines, with a minimum of 1200 rpm to start the pressure. This small inertia turbine has a long service life. Turbocharged engines used to be cooled by mechanical water pumps, but now they are cooled by electronic water pumps. After parking, they can work continuously for a period of time to cool the turbocharger, which can extend the life of the turbocharger.

Now turbocharged engines are equipped with electronic pressure reducing valves, which can reduce the impact of air flow on turbochargers, improve the working environment of turbochargers, and extend their service life.

Advantages of turbocharger:

Increase engine power. With the engine displacement unchanged, the engine can inject more fuel by increasing the intake air density, thus improving the engine power. The power and torque of the engine with supercharger can be increased by 20%~30%.

Improve engine emissions. Turbocharged engine can reduce the emission of harmful components such as particulate matter and nitrogen oxide in engine exhaust gas by improving the combustion efficiency of the engine.

Provide platform compensation function. The engine with turbocharger can overcome the engine power reduction caused by the thin plateau air.

Improve fuel economy and reduce fuel consumption. Because the engine with turbocharger has better combustion performance, which can save 3% - 5% of fuel.
