Turbochargers are used in a wide range of applications, duty cycles and different vehicle usage rates in whole world. As known, the exhaust gas temperature is still a challenge to the turbochargers manufactures once it has a considerable impact in the turbocharger durability and reliability. High temperatures can lead to thermal mechanical stress, which can cause material fatigue. Extensive works have been carried out by product and combustion engineers to guarantee that temperature limits are under acceptable values. However, there are other factors that are related to the application usage in the field that can contribute to the exhaust gas temperature increase. As known, service engineers have the difficult task of identifying the reason why some components used for years in different localities fail only in certain regions, fleet or applications. Trouble shootings are often a useful guide in the investigation, but are to generic most of the cases.
