From my understanding a lot of the pollution is just from heating up the incoming air containing nitrogen. Unless you're taking your oxidizer with you rather than using the air to burn that propane, you're still going to produce toxic-to-humans nitrogen-based oxides (pollution) from exploding the gas in the presence of nitrogen. In fact depending on how you do it (for example if the combustion temperatures end up higher) you could have significant increases of such compounds versus gasoline combustion.
Best to keep the combustion vehicles to antiques/collectables and make all daily drivers use electricity.
- Gordonjcp 4y agoBurning propane in car engines produces carbon dioxide and water, no sulphur oxides (because there's no sulphur in the fuel, or such a tiny amount that it is negligible) and no nitrogen oxides. You can actually measure this. It burns leaner than petrol resulting in complete combustion so there's no CO or HC in the exhaust, either. Indeed, if there's enough CO and HC in the environment from other vehicles you'll actually be burning that too giving it (in a sense) negative emissions figures.
