The purpose of integrated dry-sump lubrication is to guarantee a reliable oil supply while reducing engine temperatures, even in sportily driven cars.

The oil reservoir is located inside the engine, making an external tank unnecessary. Four oil pumps remove the oil from the cylinder heads directly into the oil sump. A fifth pump in the oil sump directly supplies the lubricating points in the engine.

To prevent foaming, the oil is channelled through cylinders known as swirlpots. In this way, optimum lubrication is guaranteed at all times and the oil pressure is always maintained at the necessary level in order to ensure, for example, that hydraulic valve clearance compensation remains fully functional – a condition that is crucial to the power and emission characteristics of the engine.

To reduce power losses and increase efficiency, an electronically controlled oil pump supplies the lubricating points inside the engine as and when required. This means that the oil pump does not work so hard when there is less demand for lubrication. The benefits of an on-demand oil supply system are optimum efficiency, reduced fuel consumption and lower exhaust emissions.

Single-jet spray nozzles cool the piston crowns with oil from the main lubrication circuit – another detailed solution that helps to reduce the thermal load on the engine.

For the engine, all of these detailed solutions mean a consistent supply of oil regardless of gravitational loads, even in the most demanding track conditions.
