Methods and systems for compressed natural gas (CNG)
First Claim
1. A compressed natural gas fuel system that is configured to store or deliver compressed natural gas to an engine of a vehicle, comprisinga frame assembly that partly defines an interior space;
- at least one container supported by the frame assembly and partly located within the interior space, wherein the at least one container is configured to house compressed natural gas;
the frame assembly configured to be engaged to a chassis of a vehicle at a location on the chassis that is located rearward of a cab of the vehicle or below the cab of the vehicle;
a first manifold that is in fluid connection with the at least one container;
a second manifold that is in fluid connection with the at least one container;
the first manifold is located on the frame assembly or a first location of the vehicle that houses the vehicle engine;
the second manifold is located on the frame assembly or a second location of the vehicle that houses the vehicle engine;
each manifold includes;
a fast-fill port in fluid communication with the at least one container, wherein the fast-fill port is adapted to receive a portion of compressed natural gas at a first rate; and
a fill port in fluid communication with at least one container, wherein the fill port is adapted to receive a portion of compressed natural gas at a second rate in which the second rate is less than the first rate.

Abstract
Provided is a compressed natural gas (CNG) fuel system comprising a frame, a first container, a second container, a first manifold, a second manifold, and a casing. The frame may have: a first side; a first connecting member; and a second side. The first container may be configured to house or contain CNG and be engaged to and substantially shrouded by the first side of the frame. The second container may be configured to house or contain CNG and be engaged to and substantially shrouded by the second side of the frame. The first manifold may be engaged to and substantially shrouded by the first side of the frame. The second manifold may be engaged to and substantially shrouded by the second side of the frame. The casing may at least partially surround the frame, the first container, the first manifold, and the second manifold.
