At the same time, if the exhaust muffler temperature is very high at this time, its heat can be absorbed into the turbocharger casing, and the car oil left in the turbocharger will burn into carbon deposits. Carbon deposits will affect the wear resistance and endanger the service life of the turbocharger.
