Hydrogen Injection

Interesting stuff here. If the emissions gains are enough maybe Merc can get rid of the DEF system?

Sounds like a great idea.

take a look at Empire Hydrogen inc. out of Sydney British Columbia.

attend a academic /Industry group at BCIT last week ....

Does not inject into the combustion chamber like Hy tech from Seattle does ...

wonder what the mechanical engineers / chemical engineers on the forum have to say

There is tons of hydrogen in the fuel (hydrocarbons). If it was as simple as adding extra hydrogen, manufacturers would be all over it. The reality is that you would need large amounts of hydrogen to impact nox production. Too much to easily store, and electrolysis is power hungry.

Why not just water injection. The water turning to steam will boost power output, sez me.

Conceptually
1) in "fog" apparently internal combustion engines perform better !? ?related to humidity ? which reduces the temperature in the combustion chamber and thus reduces the synthesis of oxides of nitrogen?

2)H2 acts as a assistance to /accelerant of a more complete combustion of the hydrocarbon fuel within the ignition chamber is not the primary fuel unlike a rocket where it is the primary and only fuel?

wonder what the physicist , mechanical engineers and chemical engineers have to say about this conceptually.

VW AG announced today that it cannot meet the EPA requirements as well as the requirements of the EU
