Abstract

An emission-capturing apparatus includes a tank having an inlet and an outlet. The apparatus further includes a muffler fluidly coupled with the outlet to intercept fluid exiting the outlet, permit passage of gas through the muffler, and inhibit passage of liquid through the muffler. The apparatus further includes a hose having a tank end and a distal end. The tank end is coupled to the inlet. The apparatus further includes a fitting fluidly coupled to the distal end of the hose. The fitting is configured to be fluidly coupled to an end section of an ejection port of a vehicle to receive an emission from the ejection port.

First claim

What is claimed is:

1. An emission-capturing apparatus for use in conjunction with a vehicle that includes an ejection port with an end section, the emission-capturing apparatus comprising:
a tank having an inlet and an outlet, an internal ambient pressure of the tank being at least equal to an external ambient pressure at all times;
a muffler fluidly coupled with the outlet, the muffler configured to intercept fluid exiting the outlet, to permit passage of gas through the muffler, and to inhibit passage of liquid through the muffler such that the liquid drains back into the tank;
a hose having a tank end and a distal end, the tank end fluidly coupled to the inlet of the tank; and
a fitting fluidly coupled to the distal end of the hose and configured to be fluidly coupled to the end section of the ejection port to receive an emission from the ejection port.

2. The emission-capturing apparatus of claim 1 , wherein the fitting has a first open end that is fluidly coupled to the distal end of the hose and a second open end configured to be fluidly coupled to the end section of the ejection port.

3. The emission-capturing apparatus of claim 2 , wherein the fitting is an elbow fitting.

4. The emission-capturing apparatus of claim 3 , wherein the elbow fitting has first and second quarter inch (#4) male MS fitting ends that correspondingly define the first and second open ends.

5. The emission-capturing apparatus of claim 2 , further comprising an additional hose that is disposed between the hose and the fitting and that fluidly couples the first open end of the fitting to the distal end of the hose, wherein the additional hose has a proximal additional hose end that is fluidly coupled to the distal end of the hose and a distal additional hose end that is fluidly coupled to the first open end of the fitting.

6. The emission-capturing apparatus of claim 5 , further comprising at least one adapter disposed between the additional hose and the fitting and having a first adapter open end that is fluidly coupled to the distal additional hose end and a second adapter open end that is fluidly coupled to the first open end of the fitting.

7. The emission-capturing apparatus of claim 5 , wherein the additional hose is a quarter inch inner diameter (ID) high pressure (HP) hose.

8. The emission-capturing apparatus of claim 5 , further comprising at least one adapter disposed between the hose and the additional hose and having a first adapter open end that is fluidly coupled to the distal end of the hose and a second adapter open end that is fluidly coupled to the proximal additional hose end of the additional hose.

9. The emission-capturing apparatus of claim 8 , wherein the at least one adapter has a first inch (#16) male AN fitting end that define the first adapter open end and a second quarter inch (#4) male AN fitting end that define the second adapter open end.

10. The emission-capturing apparatus of claim 8 , wherein the at least one adapter includes a first adapter having the first adapter open end and a second adapter that is fluidly coupled to the first adapter and that has the second adapter open end.

11. The emission-capturing apparatus of claim 1 , wherein the tank further includes a drain.

12. The emission-capturing apparatus of claim 11 , wherein the drain comprises a conduit and a valve.

13. The emission-capturing apparatus of claim 1 , further comprising a second muffler, wherein the tank has a second outlet and wherein the second muffler is fluidly coupled with the second outlet, the second muffler configured to intercept fluid exiting the second outlet, to permit the passage of gas through the muffler, and to inhibit the passage of liquid through the muffler.

14. The emission-capturing apparatus of claim 1 , further comprising a pressure gage fluidly coupled with the tank and configured to detect and display a pressure within the tank.

15. The emission-capturing apparatus of claim 1 , further comprising a cart having a plurality of wheels, wherein the tank is mounted to the cart.

16. A method for capturing an emission emanating from an end section of an ejection port of a vehicle, the method comprising the steps of:
positioning an emission-capturing apparatus proximate the ejection port, the emission-capturing apparatus including a tank having an inlet and an outlet, wherein an internal ambient pressure of the tank being at least equal to an external ambient pressure at all times, a muffler fluidly coupled with the outlet, the muffler configured to intercept fluid exiting the outlet, to permit passage of gas through the muffler, and to inhibit passage of liquid through the muffler such that the liquid drains back into the tank, a hose having a tank end and a distal end, the tank end fluidly coupled to the inlet of the tank, and a fitting fluidly coupled to the distal end of the hose and configured to be fluidly coupled to the end section of the ejection port to receive the emission from the ejection port;
fluidly coupling the fitting to the end section of the ejection port; and
capturing the emission emanating from the ejection port with the emission-capturing apparatus.

17. The method of claim 16 , wherein the fitting has a first open end that is fluidly coupled to the distal end of the hose and a second open end configured to be fluidly coupled to the end section of the ejection port, and wherein positioning the emission-capturing apparatus comprises positioning, proximate to the ejection port, the emission-capturing apparatus that further includes an additional hose having a proximal additional hose end that is fluidly coupled to the distal end of the hose and a distal additional hose end that is fluidly coupled to the first open end of the fitting.

18. The method of claim 17 , wherein positioning the emission-capturing apparatus comprises positioning, proximate to the ejection port, the emission-capturing apparatus that further includes at least one adapter disposed between the additional hose and the fitting, the at least one adapter having a first adapter open end that is fluidly coupled to the distal additional hose end and a second adapter open end that is fluidly coupled to the first open end of the fitting.

19. The method of claim 17 , wherein positioning the emission-capturing apparatus comprises positioning, proximate to the ejection port, the emission-capturing apparatus that further includes at least one adapter disposed between the hose and the additional hose and having a first adapter open end that is fluidly coupled to the distal end of the hose and a second adapter open end that is fluidly coupled to the proximal additional hose end of the additional hose.

20. The method of claim 16 , further comprising the step of decoupling the fitting from the end section of the ejection port when the emission has been captured by the emission-capturing apparatus.
