Magneto components. Impulse coupling components. An ignition magneto (also called a high-tension magneto) is an older type of ignition system used in spark-ignition engines (such as petrol engines). It uses a magneto and a transformer to make pulses of high voltage for the spark plugs. The older term "high-tension" means "high-voltage". [1]
The engine has a dry weight of 269.75–297 lb (122–135 kg) including the generator and starter. The ignition system consists of dual magnetos , one Scintilla S4RN-201 and one S4RN-205 or, alternatively, two Slick Electro 449 magnetos.
Mechanics nicknamed them Parts Recovery Turbines, since the increased exhaust heat meant a return to the engine destroying exhaust valves. The fuel burn for the PRT-equipped aircraft was nearly the same as the older Pratt and Whitney R-2800, while producing more useful power. [5] Effective 15 October 1957 a DA-3/DA-4 engine cost $88,200. [6]
The Rotax 503 is a 37 kW (50 hp), inline 2-cylinder, two-stroke aircraft engine, built by BRP-Rotax GmbH & Co. KG of Austria for use in ultralight aircraft. [1] [2] For decades the engine was one of the most popular and reputedly reliable aircraft engines in its class (two-stroke, under 60 horsepower), [3] and it remains widely used and ...
For redundancy, virtually all piston engine aircraft are fitted with two magneto systems, each supplying power to one of two spark plugs in each cylinder. Magnetos were used for specialized isolated power systems such as arc lamp systems or lighthouses , for which their simplicity was an advantage.
IO-390-X Four-cylinder, fuel-injected, horizontally opposed, air-cooled direct drive, 390 cubic inches (6.39 litres), 210 hp (157 kW) at 2700 rpm, dry weight 308 lb (140 kg), The "X" designation is a generic indicator for all engines in the family.
The Lycoming O-290 is a dual-ignition, four-cylinder, air-cooled, horizontally opposed aircraft engine.It was first run in 1939, and entered production three years later. A common variant of the type is the O-290-G, a single-ignition model which was designed to drive a generator as part of a ground power unit.
The Lycoming IO-720 engine is a large displacement, horizontally opposed, eight-cylinder aircraft engine featuring four cylinders per side, manufactured by Lycoming Engines. [1] There is no carbureted version of the engine, which would have been designated O-720 and therefore the base model is the IO-720. The IO-720 is the only flat-eight ...
