Benefits of technology
The system effectively delivers hydrogen to the engine during cold starts, reducing emissions and improving fuel efficiency by up to 20% while safely managing electrolyte by-products, thus addressing the limitations of existing technologies in hydrogen production and delivery.
Problems solved by technology
Gasoline is a standard fuel for internal combustion engines, but many of the bi-products of incomplete gasoline combustion are harmful to the environment.
Also gasoline is a non-renewable resource, and given worldwide trends in the supply and demand of gasoline, the upward pressure on the price of gasoline and other petroleum products will undoubtedly continue.
However, there are many obstacles to employing an electrolyzer in every day use, especially in transportation applications such as the automobile.
Pure oxygen is highly explosive, and must be safely discharged either into the atmosphere, or directly into the engine for combustion.
The electrolyte can be harmful to the environment, and must either be reused or discarded in an environmentally friendly manner.
In the automotive application, the environmental conditions also present significant difficulties.
A significant portion of the harmful emissions produced by a gasoline combustion engine are produced immediately after a “cold start,” while the engine is running below normal operating temperature.

Embodiment Construction
[0012]In one aspect the system of the invention provides a hydrogen delivery system for supplying hydrogen to a combustion engine, comprising a hydrogen storage reservoir in communication with an input port of the engine, for storing a supply of hydrogen, and a hydrogen storage release valve for retaining hydrogen in the storage reservoir and selectively releasing hydrogen from the storage reservoir when the engine is started.
[0013]In a further aspect the invention provides an electrolysis cell having at least one electrolyte input port, at least one electrolyte output port, an electrolyte circulating system for replenishing electrolyte in the electrolysis cell, and at least one gas output port for supplying hydrogen under pressure to the storage reservoir. In a still further aspect the hydrogen storage release valve selectively releases hydrogen from the storage reservoir when the electrolysis cell is not producing hydrogen

The present invention provides a system for providing hydrogen gas to inject into the intake of an internal combustion engine. A hydrogen storage reservoir in communication with the gas output port stores a supply of hydrogen, and a hydrogen storage release valve retains the hydrogen in the storage reservoir and selectively releases hydrogen from the storage reservoir when the engine is started. In the preferred embodiment the system comprises an electrolysis cell that produces hydrogen when the engine is warm, and hydrogen is released from the storage reservoir when the system is active but the electrolysis cell is not producing hydrogen.
Description
FIELD OF THE INVENTION[0001]This invention relates to systems for improving the fuel efficiency of internal combustion engines. In particular, this invention relates to electrolyte delivery systems for use with internal combustion engines.BACKGROUND OF THE INVENTION[0002]Improving the fuel efficiency of internal combustion engines has been of interest for many years. Gasoline is a standard fuel for internal combustion engines, but many of the bi-products of incomplete gasoline combustion are harmful to the environment. This has given rise to much concern over the long term effects of the prolific use of internal combustion engines. Many approaches have been taken to reducing these harmful emissions, some more successful than others, but further measures are necessary in order to meet increasingly strict emission standards. Also gasoline is a non-renewable resource, and given worldwide trends in the supply and demand of gasoline, the upward pressure on the price of gasoline and other...
