Turbochargers can get very hot during operation, as they are subjected to high temperatures and pressures. The temperature of the exhaust gases flowing through the turbine can reach up to 1,000 degrees Celsius (1,832 degrees Fahrenheit) or more, and the temperature of the compressed air being fed into the engine can reach up to 200 degrees Celsius (392 degrees Fahrenheit).
The temperature of the turbocharger itself can also get very high, especially in the turbine and compressor wheels and the bearing housing. The temperature of these components can reach up to 500 degrees Celsius (932 degrees Fahrenheit) or more in some cases.
To withstand these high temperatures, turbochargers are typically made from materials that have high heat resistance, such as cast iron, stainless steel, and ceramic. They also have cooling systems in place to help dissipate heat, such as oil coolers and water jackets.
It’s important to keep the temperature of a turbocharger within a safe range to ensure its proper functioning and to prevent damage. If the temperature gets too high, it can cause the turbo to fail or malfunction, and it can also lead to engine damage.
