    No, there are always losses in the process since the theories make a good deal of assumptions that don't always apply. That's why rather than predict accurate emissions results you have to measure it. Theory only gives you a ballpark.

          Chemistry's not exactly your strong point, is it? Energy is given off by the combustion reaction but no mass is destroyed nor do molecules of gas disappear. Every single atom that enters the combustion chamber will leave the combustion chamber......conservation of mass and energy say you fail.

          I have worked in this exact field, combustion emission engineering. How emissions are measured is that you compare the difference between sampled ambient air and sampled diluted exhaust air (dilution is a known percentage, and is diluted with gas of known concentrations and proportions). 30 lbs of CO2 from a gallon of gas is believable for an average car.

          Ambient air is, by percentage, approximated by 79% Nitrogen and 21% oxygen. In reality, it's closer to 20% oxygen and 1% CO2, Argon, and other gases. But I digress. The CO2 in the air is simply dwarfed by the CO2 produced in the combustion process. Carbons from gasoline meet a shitton of oxygen in the intake air charge, and make a fuckload of CO2s among other wonderful emission byproducts.

          You do know what stoichiometric ratio is, yes? That air/fuel ratio you strive for? In general you want 14:1 air:fuel. That means that for 1 kg of fuel (gasoline) you want 14 kg of air. CO2 is by far the largest proportional emissions species a car emits. Basically 15 kg of total gas is combusted in the engine, with a very large percentage of the result being CO2.

          Or revel in ignorance, I don't care. Also, before someone starts throwing around the global warming bit, I'm not saying anything about that. Just that the above is what happens in combustion from chemistry.

          On a side note, at toyota gas pedals picture.

          I will concede that its been a long time since Chem and that yeah brain fart, energy comes from the chemical bonds being broken,(conservation of mass) Yeah I know what Stoci, is.

          Just still seems that 30lbs of CO2 to a gallon of fuel still seems way way high.

                  Winter is ugly IMO. Makes me feel like shit.

                    Winter only looks good when the snow is falling.
                    after that the snow turns black and it looks like god shat on us

                          I thought I was the only one who thought of it this way. Thank you, oh, thank you.

                              nice 911, but those lights, and that front air intake are hideous.

                                I kinda liked the headlights... but now that you point out the front intake, it does look a little goofy.
