Hot-tube ignitor : ウィキペディア英語版 | Hot-tube ignitor A hot-tube ignitor was an early device that fit onto the cylinder head of an internal-combustion engine, used to ignite the compressed fuel/air mixture by means of a flame heating part of the tube red-hot. A hot-tube ignitor consisted of a metal or porcelain tube, closed at one end and attached to the cylinder head at the other and an adjustable burner that could be moved to position its flame at any point along the length of the tube. ==Operation== The compression stroke in the cylinder pushed some left over combustion products in the tube, followed by fresh (unburned) fuel/air mixture. When the compression was enough that the fuel reached the red-hot area of the tube, ignition occurred. On early designs, ignition timing was adjusted by adjusting the position of the red-hot spot on the tube—this was accomplished by moving the burner along the length of the tube. Most later styles used a fixed burner and varied tube lengths to change ignition timing.
