This is wrong though. They tested the kits. The kits provably don't work.

But hydrogen fuel enrichment that enables a lean burn engine to run very lean at low loads is more efficient. Provably so. The kits just don't have the sophistication to lean out the AFR. To do it properly, you'd have to add a wideband O2 sensor, and trick the ECU into running quite lean if the load was low.

Better yet would be to have a wideband, and an ECU with lean cruise built in.


Need proof? Check out this study:

ScienceDirect - International Journal of Hydrogen Energy : Hydrogen enrichment for improved lean flame stability

(i hope that link works)

Alternatively, do a google search for hydrogen fuel enrichment.
