A dry-sump system is a method to manage the lubricating motor oil in four-stroke and large two-stroke piston driven internal combustion engines. The dry-sump system uses two or more oil pumps and a separate oil reservoir, as opposed to a conventional wet-sump system, which uses only the main sump (U.S.: oil
Because of the dry sump's external oil reservoir, excess air can escape the oil before the oil is pumped back through the engine. Dry sumps also allow for more power because they reduce the amount of windage , oil sloshing up into the rotating assembly, and the vacuum from the scavenge pump improves ring seal. [ 10 ]
It has seen the modification of the cylinder heads to allow four valves per cylinder, the replacement of Weber carburettors with electronic fuel injection, and the re-engineering of the lubrication system from a wet to a dry sump design.
The developed engine features a dry sump lubrication system allowing the engine to be positioned low in the chassis, for an optimised centre of gravity. [2] The car uses the original bonded aluminium chassis supplied by Aston Martin, but uses carbon fibre panels (exc roof) and features front splitter, rear diffuser, rear wing and a flat floor.
Traditional sewage pumping stations incorporate both a wet well and a "dry well". Often these are the same structure separated by an internal divide. In this configuration pumps are installed below ground level on the base of the dry well so that their inlets are below water level on pump start, priming the pump and also maximising the ...
