REPAIR OF A DAMAGED TURBOCHARGER
Proceedings on Engineering Sciences, 2019 he turbocharger is among the highest quality assemblies for modern internal combustion engines. Its contribution to engine operation is immeasurable – it increases the power output of the engine while indirectly reducing fuel consumption. Like all devices, turbochargers require quality maintenance as they are susceptible to failure.
