 Methanol/ethanol performance
I read on one thread that there was little performance difference between ethanol and methanol when on a dyno. However, I wonder if the engine/s being tested had electronic injection systems that used a oxygen sensor in the exhaust. In which case, the extra caloric content of ethanol would likely result in a reduction of fuel flow through the electronic injection system, thus negating any perceived benefit of the higher caloric content of ethanol over methanol.
On a Turbo Diesel I understand that the methanol blend should be limited to no more than 50%. So for arguments sake I was running a 50% ethanol blend, would the extra energy content of the ethanol push the engine into detonation? In other words, are there different limits to the different alcohols in a turbo diesel?
This is an important consideration for me because I have a mechanical injection system on my TD that ceases adding fuel before full boost. If the detonation limits were the same, then I may be able to utilise the extra boost more efficiently by using ethanol wth the higher energy content.
