Hot-bulb engine
The hot-bulb engine is a type of internal combustion engine in which fuel ignites by
coming in contact with a red-hot metal surface inside a bulb, followed by the
introduction of air (oxygen) compressed into the hot-bulb chamber by the rising
piston. There is some ignition when the fuel is introduced, but it quickly uses up the
available oxygen in the bulb. Vigorous ignition takes place only when sufficient
oxygen is supplied to the hot-bulb chamber on the compression stroke of the engine.
Most hot-bulb engines were produced as one-cylinder, low-speed two-stroke
crankcase scavenged units
