Abstract
An apparatus for feeding hydrogen into an intake (11) of an engine (1), including: an air inlet (23); a hydrogen inlet (21); a mixing chamber (20) for generating a fuel mixture from hydrogen and air introduced from the inlets, the chamber being adapted to couple to the intake of the engine, for introducing the fuel mixture thereto; and control means (26) for controlling airflow through the mixing chamber. The control means may include an air speed control for varying an effective cross-section of air flow through the apparatus. The air speed control is preferably in the form of an annular collar arranged in the chamber for radial expansion or contraction.
Claims27
An apparatus for supplying a hydrogen containing gas mixture for use in hydrogen assisted combustion of an engine, the apparatus comprising:
- an air inlet for admitting air to the apparatus;
- a hydrogen inlet for admitting hydrogen to the apparatus;
- a water inlet for admitting water or a water mixture to the apparatus;
- a mixing chamber in which the hydrogen containing gas mixture is formed from mixing the hydrogen, air and water admitted to the mixing chamber, the chamber being adapted to couple to the intake of the engine for introducing the hydrogen containing gas mixture thereto for hydrogen assisted combustion of the engine;
- and
- a controller for controlling air flow through the mixing chamber;
- wherein the controller is operated to control the velocity of the air flow to supersaturate the air with the water or the water mixture admitted to the mixing chamber at a level which is up to or greater than about 100% relative humidity such that the air admitted to the chamber is supersaturated with water or the water mixture prior to the air mixing with the hydrogen to form the hydrogen containing gas mixture thereby increasing the power developed by the engine when the hydrogen containing gas mixture from the mixing chamber is admitted to the engine.
An apparatus as claimed in 13
- wherein the bladder is inflated during low engine speeds and deflated at high engine speeds.
