1. A system for selectively operating an engine either as a diesel engine or as a hydro-diesel engine, comprising:
(a) a diesel engine assembly, comprising:
(i) a diesel engine,
(ii) an injector for injecting liquid diesel fuel into the diesel engine,
(iii) a liquid diesel fuel source, and
(iv) a fuel pump for transporting liquid diesel fuel from the liquid diesel fuel source to the injector;
(b) a hydro-diesel assembly connected to the diesel engine assembly, comprising:
a hydrogen gas source, and
an infuser configured to mix hydrogen gas into the liquid diesel fuel to create a homogenized liquid/gas hydro-diesel fuel mixture;
(c) a shutoff valve system, configured to either:
(i) permit the diesel fuel to be mixed with the hydrogen gas in the infuser and then return the homogenized liquid/gas hydro-diesel fuel mixture to the fuel pump, or
(ii) isolate the hydro-diesel assembly from the diesel engine assembly; and
(d) a remote control system for selectively turning on and off the operation of the hydro-diesel assembly while the diesel engine assembly is operating.
