Basic Concepts of Turbocharger Oil Drain Connections

Turbochargers are devices that increase an engine’s power output by forcing extra air into the combustion chamber. This process, known as forced induction, allows more fuel to be burned, resulting in greater efficiency and power. The turbocharger itself is lubricated by engine oil, which is circulated through the turbocharger’s bearings and other moving parts. An oil drain connection plays a role in the turbocharger system by allowing used oil to be efficiently removed from the turbocharger, ensuring that fresh, clean oil is always available for lubrication. This helps maintain turbocharger efficiency and prevents the buildup of contaminants that could lead to decreased performance or failure ¹.
