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.
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 ...
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.
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 result was the Space Bug .049 Contest engine, Cox's first model plane engine which was completed in October 1951. [8] In 1952 the first name change was made to L.M. Cox Manufacturing Company Inc. The Space Bug engine set the scene for all the Cox engines that followed, and went into full production in 1952.
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.
In the 1950s and 1960s until recently, Cox has produced a line of hobby-oriented models of cars, airplanes, and other vehicles. The most noted are the .049 cubic-inch displacement glow fuel powered models, controlled by line (Control Line) or by radio (Radio Control).

Glow engines use glow plugs. "Diesel" model airplane engines have variable compression ratios. Both types depend on special fuels. Some 19th-century or earlier experimental engines used external flames, exposed by valves, for ignition, but this becomes less attractive with increasing compression.
