A car with an exhaust system has always had a rusted exhaust after a couple months, as there is always humidity in a cold exhaust. Which evaporates when the exhaust starts heating up.
This is thermodynamically impossible. A combustion engine gets, best case, upwards to 50 % efficiency and the electrolyzer is something similar. Even if they got it perfectly efficient no extra energy is provided into the system so all the work will come from the gasoline anyway. With real world inefficiency this will consume more energy than not using the system...
We have a proprietary process that creates high quality hydrogen and oxygen. I know it's out side the box of what has been taught. We have been in business over 16 years and we have been to several labs around the world including 2 of the CARB qualified labs in CA developing and proving out the technology. We get amazing results on engines around the world from 4L engines to over 89 L engines. We have a microcontroller that creates precise amounts of hydrogen and oxygen by catalysis. This is why we get the amazing results. We are committed to researching and advancing the technology.
