Cycleshop, thank you.
morons out there think that internal combustion engines are 99% efficient and we can't get any more energy out of them. Think about it,
1) we're combusting gasoline with air, which is only 20% oxygen, 70% nitrogen, of course this isn't efficient and we produce harmful NOx gases in the process.
2) that's why we need catalytic converters, also to burn up any unburned gasoline
3) that's why we need oxygen sensors, to allow enough oxygen to get through to the catalytic converter that it can reduce those NOx gases and combust the gasoline
4) it is well known that a small amount of hydrogen allows gasoline to ignite and combust more evenly, therefore you need less gasoline to do the same amount of work.
5) injecting hydrogen will provide a more complete, efficient burn that not only uses less gas, it produces fewer harmful exhaust gases.
Is it the answer? no, but it's a cheap solution that can only help.
