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 pan) below the engine and a single pump. A dry-sump engine requires a pressure relief valve to regulate negative pressure inside the engine, so internal seals are not inverted.
It is generally located inside the lower part of the engine, usually below and/or to one side of the crankshaft. On dry sump engines, at least two oil pumps are required: one to pressurize and distribute the oil around the engine components, and at least one other 'scavenge pump' to evacuate the oil which has pooled at the bottom of the engine.

Dry sump engines in some drag racing cars use scavenging pumps to extract oil and gases from the crankcase. [18] A separator removes the oil, then the gases are fed into the exhaust system via a venturi tube. [citation needed]. This system maintains a small amount of vacuum in the crankcase and minimises the amount of oil in the engine that ...
Crankcase-compression designs are often used in small petrol (gasoline) engines for motorcycles, generator sets and garden equipment. This design has also been used in some small diesel engines, however it is less common. Both sides of the piston are used as working surfaces: the upper side is the power piston, the lower side acts as a pump.
The Rolls-Royce C range was a series of in-line 4, 6 and 8 cylinder diesel engines used in small locomotives, railcars, construction vehicles, and marine and similar applications. They were manufactured by the Rolls-Royce Oil Engine Division headed by William Arthur Robotham to 1963, initially at Derby and later at Shrewsbury , from the 1950s ...
The EMD 710 is a line of diesel engines built by Electro-Motive Diesel (previously General Motors' Electro-Motive Division). The 710 series replaced the earlier EMD 645 series when the 645F series proved to be unreliable in the early 1980s 50-series locomotives which featured a maximum engine speed of 950 rpm.
A full-flow system will have a pump which sends pressurised oil through a filter to the engine bearings, after which the oil returns by gravity to the sump. In the case of a dry sump engine, the oil that reaches the sump is evacuated by a second pump to a remote oil tank. The function of the full-flow filter is to protect the engine from wear ...
Compared to the standard AMG engine, the SLS's engine includes an all-new intake system, reworked valvetrain and camshafts, the use of flow-optimised tubular steel headers and dethrottling of the exhaust system. The engine also utilizes a dry-sump lubrication system to lower the center of gravity of the car. [3]
