A search on detonation produced some of the causes of detonation, but everything I found says there are other causes, but none list them.
The most common listed cause is the air / fuel mixture becoming too hot due to compression by a turbo. When it gets hot enough it spontaneously detonates. Oddly I don't find references to superchargers having this effect. So, a few questions:
- What are the other causes of detonation?
- What are the various methods of managing detonation? For turbos an intercooler seems to be a common way to cool the air / fuel mixture. What others have been tried?
- Do superchargers have the same effect of heating the air / fuel mixture? And if not, why not? By ideal gas law (PV = nRT) I thought increasing only the pressure would by necessity increase the temperature.
