Model diesel engines are instead a carbureted two-stroke using the crankcase for charge-air compression. The carburetor supplies a mixture of fuel and air into the engine, with the proportions kept fairly constant and their total volume throttled to control the engine power. Apart from sharing the diesel's use of compression ignition, their ...
Interest in diesel engines in the postwar period was sporadic. The lower power-to-weight ratio of diesels, particularly compared to turboprop engines, weighed against the diesel engine. With fuel available cheaply and most research interest in turboprops and jets for high-speed airliners, diesel-powered aircraft virtually disappeared.
A model engine is a small internal combustion engine [1] typically used to power a radio-controlled aircraft, radio-controlled car, radio-controlled boat, free flight, control line aircraft, or ground-running tether car model.
The fuel used to power the engine is called Model Engine Fuel, a mixture of methanol (70–40%), castor oil (20%) and nitromethane (10–40%). The Cox line of reed valve engines designed prior to 1960 used a rear reed valve induction system.
Glow fuel is a fuel source used in model engines – generally the same or similar fuels can be used in model airplanes, helicopters, cars and boats. [1] Glow fuel can be burned by very simple two-stroke engines or by more complicated four-stroke engines, and these engines can provide impressive amounts of power for their very small size.
A glow plug engine, or glow engine, is a type of small internal combustion engine [1] typically used in model aircraft, model cars and similar applications. The ignition is accomplished by a combination of heating from compression, heating from a glow plug and the catalytic effect of the platinum within the glow plug on the methanol within the ...
The Zoche aero-diesels are a trio of radical German prototype diesel radial aero-engines intended for light aircraft, designed by Michael and Georg Zoche in the 1990s. [1] Zoche aero-diesels are modular piston engines and are all direct-drive, air-cooled, radial two-stroke diesels with up to four cylinders per row.
The diesel engine's high compression results in better fuel efficiency and the higher operating rpm of the Centurion allows higher power to be developed from a smaller displacement, in comparison to conventional aircraft piston engines (i.e. engines that require leaded aviation gasoline with a very high octane rating).
