Exhaust intake bonnet for capturing exhausts from diesel-powered locomotives
First Claim
1. A system for processing diesel locomotive exhaust, the system comprising:
- an Emissions Control Unit (ECU) for processing locomotive exhaust;
at least one parallel duct running parallel to train tracks the duct including an extendable and compressible inner duct residing in the at least one parallel duct and the extendable and compressible inner duct is adapted to extend and compress within the at least one parallel duct to allow movement of the locomotive along the train tracks;
a slot forming a longitudinal opening into the at the least one parallel duct, the slot running substantially the length of the at the least one parallel duct;
seals running the length of the slot and ordinarily closing the slot to resist the escape of exhaust emitted from a locomotive exhaust pipe from the at least one parallel duct;
a duct transport unit adapted to slide along the at least one parallel duct and to open the seal as the duct transport unit slides along the at least one parallel duct, wherein the seal closes behind the duct transport unit;
a bonnet for capturing the exhaust emitted from the locomotive exhaust pipe;
a vertical duct connecting the bonnet to the duct transport unit carrying the captured exhaust from the bonnet to the duct transport unit; and
a connecting duct connected to the at least one parallel duct for carrying the exhaust from the at least one parallel duct to the ECU.

Abstract
A bonnet captures exhaust gases from the exhaust pipes of diesel-powered locomotives. The bonnet includes a shell with a compliant fender. One or more of the bonnets are positioned over the exhaust pipe or pipes of the locomotive and are secured to the exhaust pipes or to a top surface of the locomotive. The bonnets are connected to a manifold, and the manifold carries the exhaust gasses to an Emissions Control Unit (ECU) for processing. The bonnets enclose a volume above and/or around the exhaust pipes and the compliant bumper closes against the internal or external surface of the exhaust pipe or pipes or against the top surface of the locomotive surrounding the exhaust pipe or pipes. The closing prevents or limits outside air from entering the bonnet and the exhaust gases from being emitted to the atmosphere.

9. A bonnet for capturing locomotive exhaust, the bonnet comprising:
-
a shell forming a volume for enclosing a single locomotive exhaust pipe and capturing exhaust from the locomotive exhaust pipe and held in place by an electromagnet; and a vertical duct connected to the shell and in fluid communication with the shell for receiving the exhaust captured by the shell, wherein the bonnet is moveable to position over the locomotive exhaust pipe, wherein the bonnet is not in direct contact with the single locomotive exhaust pipe and the bonnet relies on receiving locomotive exhaust from the enclosed volume around the single locomotive exhaust pipe. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A system for processing diesel locomotive exhaust, the system comprising:
-
an Emissions Control Unit (ECU) for processing locomotive exhaust; a bonnet for capturing locomotive exhaust emitted from a locomotive exhaust pipe of a locomotive; and an ECU rail car comprising; a tower, a boom extending from the tower; and duct supports held by the boom, wherein; the ECU is mounted on the ECU rail car; a manifold comprises at least one connecting duct supported by the duct supports and providing fluid communication between the bonnet and the ECU; and the ECU rail car is carried on train tracks and the locomotive is carried by the same train tracks.

22. A bonnet for capturing locomotive exhaust, the bonnet comprising:
-
a shell forming a volume for enclosing a single locomotive exhaust pipe and capturing exhaust from the locomotive exhaust pipe; and a vertical duct connected to the shell and in fluid communication with the shell for receiving the exhaust captured by the shell, wherein the bonnet is moveable to position over the locomotive exhaust pipe; wherein the shell comprises a tent and a frame, wherein the frame attaches to a hinge and the hinge and the frame are independently vertically supported, wherein vertically adjusting the hinge with respect to the frame causes the frame to narrow and widen. - View Dependent Claims (23, 24)
