How Long Does a BMW Turbocharger Generally Last?

[AlyssaRose]

Turbocharger lifespan is generally around 250,000 kilometers. Working Principle: The turbocharger increases air intake by compressing air, utilizing the inertial force of exhaust gases expelled by the engine to drive the turbine in the turbine chamber. The turbine, in turn, drives the coaxial impeller, which compresses air delivered through the air filter pipeline, pressurizing it into the cylinders. Note: As engine speed increases, the exhaust gas expulsion speed and turbine speed also increase synchronously. The impeller then compresses more air into the cylinders. The increased pressure and density of the air allow for more fuel to be burned, and by correspondingly increasing the fuel quantity and adjusting the engine speed, the engine's output power can be enhanced. Turbine Speed: Under full engine load, the turbine speed can reach as high as 180,000 to 200,000 RPM. Consequently, the turbocharger operates in a very harsh environment, with extremely high speeds that directly impact its lifespan.
