Basic Purpose of Oil
System design
Wet Sump
banking in engines
In a stock motorcycle engine, the oil is stored in the oil pan as an internal oil pan. This is called a “wet sump” oil system. On a motorcycle, this works during hard lateral turns because the motorcycle itself leans into the turn, allowing the oil pickup to remain submerged during the turn. In a four wheeled vehicle, the engine cannot tilt into the turn, and the oil is forced against the side of the pan.
Accumulator
Dry Sump
In a dry sump oil system, the oil for the engine is stored in an external reservoir. The oil that collects at the bottom of the engine is quickly removed by a scavenging pump, and routed into the external reservoir from which the supplies for the engine and the turbocharger are drawn. A common industry solution, a dry sump is often used in very high performance engines for a variety of reasons, including reducing the load on the engine by pumping the oil electrically, or reducing the frictional work the engine has to overcome by reducing windage. A dry sump is common in FSAE for forced induction applications as high lateral accelerations reached in the FSAE competition greatly increase the chances of temporary oil starvation of the turbocharger[1].
Oiling for Turbochargers
The engine has a robust internal oil management and supply system, so a brief or inconsistent oil supply will have limited consequences for the engine itself. However, the turbocharger is spinning at well over 200,000 rpm, meaning even a small perturbation in oil supply will spell disaster for the bearing system.
