Direction Oxygen Injection makes zero emission vehicles?

I am thinking of doing a new project on reducing engine emissions. During intake stroke engine intake air thorough atmosphere which contains more amount of nitrogen than oxygen. This leads to creation of NOx at high temperature which has been the biggest drawback. Any way this NOx can be reduced by using Exhaust Gas Re-circulation and also by adding stratified fuel injection which burns complete mixture there by reducing unburnt HC. My idea is to injection pure oxygen into the combustion chamber so that no NOx formation will occur and by stratified injection we can minimize HC also. Hence there will be Zero emissions. Now i need some techniques to separate oxygen from air and water to get pure hydrogen or oxygen. The separation process should happen even during vehicle movement by taking air into it and send oxygen only into the combustion. Any one has ideas???????

It will cost a bomb for automobile applications. Molecular sieves can selectively absorb nitrogen and allow nearly pure Oxygen to go through. You may need a plant producing about 6 cu.mtr. oxygen/hr for a small car. The plant with associated hardware will be expensive, bulky and heavy. Regeneration of the molecular sieve online will require either electric power or heat from fuel.

In my opinion a non-starter.

nice question and a innovative idea but as Ramani sir said, the feasiblity of producing o2 will be a doubt and more expensive.No one ever wanted to spend huge money for the o2 separation alone.But if you come up with a cheap abd best method to separate O2 from air,you can reach great heights and it will becone the best option available for present automobile scenario.All the best for your project.

what about using the technique of hydrogen fuel cell?????????

Hydrogen fuel cells need more Hydrogen and storing hydrogen gas is dangerous and not easy

We need more Hydrogen for this process as Hydrogen required for a mole of Oxygen is twice. So we are not going to have that any time soon.

PS: Who wants to repeat the Zeppelin accident again now
