But when the temperature is different, the mix will be incorrect. |
To get a perfect fuel mix regardless of the temperature difference, a circuit can be used to calculate which gas mixer setting to use. The gas mixer will accept decimal values, so it's incredibly accurate. This allows it to always make a perfect 1:2 mix. Just don't forget that making hot fuel will lead to explosions, if that should happen, please enjoy the strongest and most perfect explosion possible. | To get a perfect fuel mix regardless of the temperature difference, a circuit can be used to calculate which gas mixer setting to use.
