Is It Normal for a Turbocharger to Rust?

[SanGriffin]

It is quite normal for a turbocharger to rust because the turbocharger is a relatively concealed part of the engine, and working under high temperature and pressure inevitably leads to rust. Below are detailed explanations about turbochargers: 1. Working Principle: The turbocharger utilizes the inertial impulse of the engine's exhaust gases to drive the turbine in the turbine chamber. The turbine then drives the coaxial impeller, which compresses the air delivered through the air filter pipe, forcing it into the cylinders under increased pressure. 2. Advantages: The greatest advantage of turbocharging is that it significantly enhances the engine's power and torque without increasing the engine displacement. Turbocharged engines are not only more fuel-efficient but also reduce CO, CH, and PM emissions.
