Dry sump how does it work

This is accomplished using an extensive route of silicone and metal piping that travels from the reservoir to wherever the lubrication is needed. The external reservoir means that oil starvation is a thing of the past as long as the pump is fully reliable so the life span of an engine — especially in motorsport — is greatly increased.

The specific routing of the oil by the oil lines means that you can also be very specific with where the lubricant is being applied. A small sump still exists to collect the oil that makes its way to the base of the engine but it is very shallow and the excess oil is quickly scavenged back to the external reservoir.

Another simpler method of avoiding oil starvation is baffling. By welding in slats of metal within the sump or onto a metallic sump gasket, the oil will slosh into these small barriers, keeping a much larger amount of liquid within the catchment area for the oil pick-up.

Although this is not a fool-proof method against starvation, it is a much cheaper solution for most manufacturers instead of a full dry sump system which can require a whole load of reconfiguration within the engine bay.

An engine starved of oil gets very hot very quickly, along with wear on the moving parts dramatically increasing, potentially leading to catastrophic engine failure.

The second is horsepower. If the oil sloshes enough that the crankshaft has to cut through the heavy fluid, that is lost power.

A dry sump also prevents the oil pickup from ever sucking air and starving the bearings for a moment—which can cause catastrophic failure. In this video, Stephan Papadakis takes a pump apart and explains each of the parts and how they interact.

From the toothed belt that drives the pump to the design of the oil pan, take a look inside and get a better understanding of this high-tech system. It might be just what your next engine build needs.

Maintenance and Tech. Lubricate your curiosity with this video explaining dry sump oil systems Kyle Smith. A Story About. Well, it's probably easiest to explain what it isn't. It's not like the oil system on most production cars. In most cars, your engine has an oil pan or sump at the bottom of the block where all the engine's oil is collected via gravity and then sucked up by a single pump to be circulated throughout the engine.

A dry sump system also has an oil pan at the bottom of the block, but it is much smaller and has a few extra components, as the magnificent Stephan Papadakis of Papadakis Racing shows us in his video. It's also a lot more expensive, which is why it's usually seen on sports cars and race cars.

A wet sump system is simple, easy to manufacture and enough for 99 percent of cars on the road. A dry sump comes into play when you have a vehicle that experiences exceptionally high G-forces from cornering, rapid acceleration and strong braking.

In a wet sump engine, your oil will slosh around under those conditions and could cause the oil pump pickup tube to be uncovered, starving the engine of oil. In a dry sump, the multiple oil pickups in the sump, each with individual pumps all feed to a large oil tank that supplies the engine under pressure.
