2. Dry sump - Wikipedia

   en.wikipedia.org/wiki/Dry_sump

   More complex dry-sump systems may scavenge oil from other areas where oil may pool, such as in the valvetrain. Power can be further increased if the dry-sump system is designed to create a vacuum inside the crankcase, which reduces air drag (or 'windage') on moving parts as well. Improved pump efficiency to maintain oil supply to the engine.

3. Crankcase ventilation system - Wikipedia

   en.wikipedia.org/wiki/Crankcase_ventilation_system

   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 ...

4. Oil pump (internal combustion engine) - Wikipedia

   en.wikipedia.org/wiki/Oil_pump_(internal...

   The oil pump forces the motor oil through the passages in the engine to properly distribute oil to different engine components. In a common oiling system, oil is drawn out of the oil sump (oil pan, in US English) through a wire mesh strainer that removes some of the larger pieces of debris from the oil. The flow made by the oil pump allows the ...

   During the development process for the 997.2 generation of 911 engines, Porsche built out this engine oil sump rig to test its new integrated sump system. It't a crazy bit of equipment to watch in ...

6. Wet sump - Wikipedia

   en.wikipedia.org/wiki/Wet_sump

   Within piston engines, a wet sump is part of a lubrication system whereby the crankcase sump is used as an integral oil reservoir. An alternative system is the dry sump, whereby oil is pumped from a shallow sump into an external reservoir. [1] Piston engines are lubricated by oil which is pumped into various bearings, and thereafter allowed to ...

7. Lycoming O-435 - Wikipedia

   en.wikipedia.org/wiki/Lycoming_O-435

   Vertically-mounted engine model for helicopters, with a dry sump oil system, with crankcase and oil sump modifications for increased strength. It produces 260 hp (194 kW) at 3400 rpm for takeoff, with a compression ratio of 7.3:1, a dry weight of 390 lb (177 kg) and fitted with a Marvel MA-4-5 or MA-4-5AA carburetor.
