Hello there,
have been doing some reading about "safe" effective compression ratios.
for those that dont know what it is, go here www.google.com.au
Most of the sites i find are in america and thus refer to use of 92 RON fuel.
They state that for an engine running 92RON and a
Roots type SC - safe ECR = 12.5:1
Centrifugal SC? - safe ECR = 13.5:1
now to my question,
What effect would an increase in OCTANE rating of fuel used have on lifting the safe ECR level? Would the increase be significant?
Cheers,
Adam
