1. A method of enhancing diesel fuel combustion through the use of a mixer for mixing hydrogen into a liquid diesel fuel prior to combusting the fuel mixture in a combustion chamber, comprising:
(a) providing a supply of liquid diesel fuel;
(b) passing the liquid diesel into a mixer having a mixing chamber;
(c) bubbling hydrogen gas into the liquid diesel fuel in the mixing chamber;
(d) agitating the hydrogen gas within the liquid diesel fuel to form a homogenous fuel mixture;
(e) moving the homogenous fuel mixture out of the mixing chamber;
(f) pressurizing the homogenous fuel mixture thereby reducing the size of hydrogen bubbles in the homogeneous fuel mixture;
(g) receiving oxygen into a combustion chamber through an air intake;
(h) compressing the air within the mixing chamber by raising a piston in the combustion chamber causing the air to heat;
(i) injecting the pressurized homogenous fuel mixture into a combustion chamber;
(j) exposing the homogenous fuel mixture to a lower pressure in the combustion chamber thereby permitting the size of the hydrogen bubbles to expand and disperse the diesel fuel mixture throughout the combustion chamber; and
(j) permitting the homogenous fuel mixture to spontaneously combust in the combustion chamber, wherein the hydrogen gas and oxygen gas are introduced into the mixing chamber through a hydrogen-oxygen mixing system that permits:
hydrogen gas alone to enter a liquid-gas mixing chamber,
oxygen gas alone to enter the liquid-gas mixing chamber,
hydrogen gas and oxygen gas to be mixed together and then enter the liquid-gas mixing chamber together, or
hydrogen gas and oxygen gas to separately enter the liquid-gas mixing chamber.
