What is 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.
Most hot-bulb engines were produced as one or two-cylinder, low-speed two-stroke crankcase scavenged units. —Wikipedia
