1. A method of enhancing fuel combustion in an engine, comprising:
(a) providing an engine having,
(i) a combustion chamber,
(ii) a gas intake into the combustion chamber,
(iii) a fuel intake into the combustion chamber, and
(iv) a gas exhaust out of the combustion chamber;
(b) providing a hydro-diesel system including:
(i) a diesel fuel source,
(ii) a hydrogen gas source,
(ii) an infuser configured to mix hydrogen gas received from the hydrogen gas source into diesel fuel received from the diesel fuel source into a homogeneous mixture of hydrogen gas and liquid diesel fuel;
(c) providing an oxygen concentrator, wherein the oxygen concentrator receives air therein and removes nitrogen from the air to produce a concentrated oxygen gas;
(d) supplying the concentrated oxygen gas through the gas intake into the combustion chamber;
(e) supplying liquid fuel into the combustion chamber; and
(f) combusting the concentrated oxygen gas and liquid fuel in the combustion chamber.
