What are the precautions for using a turbocharger?

Turbocharger usage precautions are: 1. After starting the engine, especially in winter, let it idle for a period of time to allow the lubricating oil to fully lubricate the bearings before the turbocharger rotor operates at high speed; 2. After prolonged high-speed operation of the engine, do not shut it off immediately; 3. When disassembling the turbocharger, maintain cleanliness and ensure all pipe connections are properly blocked with clean cloth to prevent debris from entering and damaging the rotor. A turbocharger is essentially an air compressor that uses the inertial force of exhaust gases from the engine to drive a turbine in the turbine chamber. The turbine then drives a coaxial impeller, which compresses air delivered from the air filter pipe, pressurizing it into the cylinders. As engine speed increases, the exhaust gas velocity and turbine speed also increase synchronously, allowing the impeller to compress more air into the cylinders. The increased air pressure and density enable more fuel to be burned, correspondingly increasing fuel supply and adjusting engine speed to enhance the engine's output power.
I've been using turbocharged cars for many years, and I feel the most important things to pay attention to are the handling during startup and shutdown. Before driving, it's best to let the engine warm up for a minute or two, and don't rush to step on the gas pedal too hard. Before parking, let the engine idle for half a minute to allow the turbo to cool down; otherwise, residual hot oil can easily burn out the bearings. Also, always choose fully synthetic oil—don't skimp on this expense, as it helps lubricate the turbo blades to prevent wear. On the road, avoid constantly driving at high speeds and keep the RPM within a reasonable range. During regular maintenance, check the air filter—too much dust can clog the intake and affect turbo performance. In the summer heat, pay extra attention to ensure the cooling system is working properly. These habits can help prolong the life of your turbo.
