Technology / Re: Does hydrogen and oxygen fed to a petrol engine improve performance?
« on: 26/11/2013 00:16:17 »modern engine management systems already did that by measuring the O2 in the exhaust gases.Quite so. No matter what claims the HHO (snake oil) salesmen make for their devices, none of them should (seriously) be expecting customers to believe such a device makes up any more than the tiniest fraction of mass flow into an engine... the small adjustment to keep at stoichiometric ratio is well within the parameters of the car's ECU anyway.
If a little of the air were replaced by a mixture of H2 and O2 the engine system could compensate by adding slightly more air or equivalently, slightly less petrol.
