The LIO-320 is a "left-handed" version with the crankshaft rotating in the opposite direction for use on twin-engined aircraft to eliminate the critical engine. [ 2 ] [ 3 ] The first O-320 (with no suffix) was FAA certified on 28 July 1953 to CAR 13 effective 5 March 1952; this same engine was later re-designated, without change, as the O-320 ...
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
Lubrication is dry sump, and fuelling is via dual CV carburetors or fully redundant electronic fuel injection. The electronic fuel injected Rotax 912iS is a recent development. [5] The 912's lubrication system differs from most dry-sump designs in that oil is forced into the storage tank by crankcase pressure rather than by a separate scavenge ...
Normally known by the term "rotary engine", the usually air-cooled radial configuration, rotating-crankcase Otto cycle engines were used by many "pioneer era" (1903–1914) aircraft and World War I combat aircraft. These engines were designed to have a total-loss lubrication system, with the motor oil held in a separate tank from the fuel in ...
Fuel system: electronic fuel injection; Fuel type: gasoline minimum MON 85, RON 95, AKI 91, leaded or unleaded, avgas 100LL, maximum ethanol 10%; Oil system: dry sump, forced lubrication with separate oil tank; Cooling system: air cooled with liquid cooled cylinder heads; Reduction gear: mechanical gearbox, 2.54:1 ratio
A lubrication system serves to ensure lubrication of the bearings and gears and to maintain sufficiently cool temperatures, mostly by eliminating friction. The lubricant can also be utilized to cool other parts such as walls and other structural members directly via targeted oil flows.
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 ...
Base model, vertically-mounted engine for helicopters, with a dry sump oil system and side-mounted AN type accessory drives. It produces 260 hp (194 kW) at 3400 rpm for takeoff, with a compression ratio of 7.3:1, a dry weight of 396 lb (180 kg) and fitted with a Marvel MA-4-5 or MA-4-5AA carburetor. Type certified on October 11, 1954.
