Great, thanks :D

So I have to do a stoichiometric analysis for each mix?

I'm doing it all theoretical for now so I only have to adjust the air to fuel ratio when changing fuels so I think that's ok. I'm also using the fuel Mass

Hello chemists, need some help here. I'm trying to calculate the power output of a certain otto cycle using different fuels, specifically gasoline, ethanol and different combinations of the two like 85% ethanol and 15% gasoline or 50% ethanol and 50% gasoline. However I have found it difficult...

Ohhh right, should have been a duh, thanks. So no I think the air fuel ratio is 14.7 I'll adjust for this thanks again.

Thanks for the reply, but I'm still confused, I thought the heat of combustion already considered the enthalpy of formation of the products or am I missing the point?

I have been trying to determine the efficiency of an ideal Otto cycle based on the compression ratio of my car and the heat of combustion of gasoline and I think I'm not entierly wrong but there is something quite off. When trying to calculate the temperature of the combustion stage my result...
