A dual-chamber electrolysis vessel safely stores HHO gas for use by an internal combustion engine.

Safety of vehicles employing an electrolysis generator is improved by a rollover abatement system.

HHO gas is introduced to a diesel particulate filter to improve combustion of a fuel to aid in regeneration.

A dual-chamber onboard electrolysis system is configured to produce HHO gas for heavy duty trucking applications.

An HHO gas stream for use in an internal combustion engine is heated by heat exchange from with an exhaust gas stream from the internal combustion engine.

Timing of HHO gas injection into a 4-stroke engine is optimized based on engine operating parameters to improve fuel economy.

Injection of HHO gas to plural injection points about an internal combustion engine is controlled based on combustion timing parameters.

HHO gas is distributed proximate combustion chambers of a diesel engine and to a diesel particulate filter regeneration system.

An ultra low quantity of HHO gas is introduced to an internal combustion engine to improve fuel economy and/or reduce engine-out emissions, for example in a vehicle or generator.

In accordance with the principals of the present invention, an electrolytic generator and method of electrolytic generation are provided. An electrolytic stack includes of a first electrode, a second electrode, and a polymer-electrolyte membrane placed between the first and second electrodes. A first fluid passage provides fluid passage over the first electrode while a second fluid passage provides fluid passage over the second electrode. A third fluid passage provides fluid connection between the first fluid passage and the second fluid passage such that the fluid flows from the first fluid passage to the second fluid passage via the third fluid passage. An electronic current is provided between the first electrode and the second electrode when a voltage bias is applied to the electrodes.
