>>13706549>Pure oxygen tank>On a fucking carClearly the mind of a scientist, not an engineer. Pure oxygen would need to be stored in one od three ways. As a compressed gas, a compressed liquid, or a cryogenic liquid. Compressed gas means low pressure and low capacity, since gasses are low density. Compressed liquid provides much higher capacity, but also much more weight for a strong enough tank. Not to mention any damage to the tank could lead to catastrophic explosion. Cryogenic liquid oxygen would need to be kept at around -200°C or else it would evaporate. In addition to not being practical, all three pose significant risks. Your car moves around at high speeds, and has the potential to crash or be impacted. Storing flammable gasoline is already risky, since it can leak out and catch fire in the event of an accident. If you have oxygen storage on your vehicle too, now you essentially have a bomb waiting to explode. Sourcing oxygen from the air is a safety feature, since it limits the ability of your gas to explode. Not to mention there are strict safety standards for transporting compressed gasses or compressed liquids, since even having them in a vehicle is risky as fuck.
If you really want to increase combustion efficiency, you could implement some sort of oxygen purifier that could extract oxygen from the air, and immediately use it in the engine, maybe with a small, low pressure buffer tank. But even then, you would need some kind of inert gas as well, like nitrogen. Oxygen and fuel make up a relatively small proportion of the gas in your combustion chamber. Having a large volume of air in there allows for greater expansion potential after combustion, allowing the engine to do more work, and output more power from the energy is has to work with. Even if you had both oxygen and nitrogen extractors and a system that would mix them in perfect ratios, that would still sap power from the engine, which likely would give you lower fuel efficiency overall.
