These results showed clearly that liquefied acetylene was far too dangerous for general introduction for domestic purposes, since, although the occasions would be rare in which the requisite temperature to bring about detonation would be reached, still, if this point were attained, the results would be of a most disastrous character.
In order for detonation to occur, a sphere of plutonium has to be rapidly compressed by a series of conventional high explosives.
If this is not true can somebody explain how the detonation of a small amount of TNT can produce megatons of explosive force?
Skimming the head also increases the compression ratio and to avoid detonation with low octane fuel a low compression piston is used.
Detonation is generally caused by excessive heat, excessive cylinder pressure, improper ignition timing, inadequate fuel octane or a combination of these.
