Abstract

A system for remotely monitoring and controlling operation of a hydro-diesel engine, having: (a) a diesel engine assembly; (b) a hydro-diesel assembly connected to the diesel engine assembly; (c) a remote control system; and (d) a remote computer system in communication with the remote control system, wherein the remote computer system is configured to instruct the remote control system to turn off operation of either: (i) the hydro-diesel assembly while permitting the diesel engine assembly to continue operation while the hydro-diesel assembly is not operating, or (ii) both the hydro-diesel assembly and the diesel engine assembly.

Claims (62)

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.

2. The system of claim 1 , wherein the remote control system turns off the hydro-diesel assembly based on financial data received by the remote control system.

3. The system of claim 1 , wherein the remote control system simultaneously communicates with the remote control systems in a plurality of vehicles and is configured to turn off operation of the hydro-diesel assembly of each of the plurality of vehicles.

4. A system for selectively operating an engine either as a diesel engine or as a hydro-diesel engine, comprising:

(a) a diesel engine assembly;

(b) a hydro-diesel assembly connected to the diesel engine assembly;

(c) a shutoff valve system for isolating the hydro-diesel assembly from the diesel engine assembly; and

(d) a remote control system for selectively turning off the operation of the hydro-diesel assembly while the diesel engine is in operation.

5. The system of claim 4 , further comprising:

(e) a remote computer system in communication with the remote control system, wherein the remote computer system is configured to instruct the remote control system to turn off operation of the hydro-diesel assembly.

6. The system of claim 5 , wherein the remote computer system turns off operation of the hydro-diesel assembly based on financial data received from the remote computer system.

7. The system of claim 5 , wherein the remote computer system simultaneously communicates with the remote control systems in a plurality of vehicles.

8. The system of claim 4 , further comprising:

(f) a monitoring system for monitoring the operation of either or both of the hydro-diesel assembly or the diesel engine assembly.

9. The system of claim 8 , wherein the monitoring system determines whether the operational characteristics are within pre-determined safety parameters.

10. The system of claim 4 , wherein the hydro-diesel assembly comprises:

a hydrogen gas source, and

an infuser/mixer,

wherein the hydro-diesel assembly is configured to mix hydrogen gas into the liquid diesel fuel in the infuser/mixer to create a homogenized liquid/gas hydro-diesel fuel mixture.

11. The system of claim 10 , wherein the shutoff valve assembly comprises:

a shutoff valve between the hydrogen gas source and the infuser/mixer,

a shutoff valve between a diesel fuel source and the infuser/mixer,

a shutoff valve between the infuser/mixer and a fuel pump, and

a shutoff valve between the diesel fuel source and the fuel pump.

12. The system of claim 10 , wherein the hydro-diesel assembly further comprises:

a hydrogen reformer system for extracting hydrogen gas from the liquid diesel fuel source and injecting the extracted hydrogen gas back into the liquid diesel fuel prior to the liquid diesel fuel entering the infuser/mixer.

13. The system of claim 10 , wherein the hydro-diesel assembly further comprises:

an oxygen source configured to send concentrated oxygen into:

the infuser/mixer, or

the combustion chamber.

14. The system of claim 10 , wherein the hydro-diesel assembly further comprises:

a gas additives source configured to send gas additives into the infuser/mixer.

15. A system for selectively operating an engine either as a diesel engine or as a hydro-diesel engine, comprising:

(a) a diesel engine assembly;

(b) a hydro-diesel assembly connected to the diesel engine assembly, wherein the hydro-diesel assembly is 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 for isolating the hydro-diesel assembly from the diesel engine assembly;

(d) a remote control system for selectively turning off the operation of the hydro-diesel assembly; and

(e) a remote computer system for controlling operation of the remote control system.

16. The system of claim 15 , wherein the remote computer system simultaneously controls the operation of a plurality of remote control systems in a fleet or collection of hydro-diesel vehicles.

17. The system of claim 15 , wherein the remote control system adjusts operation of the hydro-diesel assembly to increase the efficiency of the hydro-diesel engine.

18. The system of claim 15 , wherein the monitoring system comprises at least one of the following sensors:

a liquid flow sensor, a gas flow sensor, a vibration sensor, a pressure sensor, a fuel gage sensor, a gas gage sensor, and a temperature sensor.

19. The system of claim 15 , wherein the hydrogen gas source is:

a hydrogen tank,

a reformer, or

an electrolysis system.

20. The system of claim 15 , wherein the hydrogen gas and the liquid diesel fuel are mixed in an infuser/mixer and the infuser/mixer comprises at least one of:

a passive agitation system within the infuser/mixer,

an active agitation system for vibrating the infuser/mixer, or

a heating system for raising temperatures in the infuser/mixer.
