DETAILED DESCRIPTION

[0043] Embodiments of the provided subject matter relate to methods and systems for utilizing compressed natural g fuel source for a vehicle. A compressed natural gas (CNG) system can include a one or more containers that house a portion of compressed natural gas (CNG). The one or more containers can be vertically or horizontally oriented with connective means behind a driver cabin of the vehicle or underneath a portion of a cabin of the vehicle, or to one or both of the sides of the vehicle such that the one or more containers are unrestricted to designs of vehicles as well as vehicle performance (e.g., aerodynamics, towing capacity, hitching techniques, among others), wherein the connective means allow for container expansion and contraction with the use of a rail connection system.

[0044] A first container can be located on a driver-side of a frame of the vehicle and attached thereto whereas a second container can be located on a passenger-side of the frame of the vehicle and attached thereto. Such attachment can be a saddling of the frame with a container on each side. The one or more containers can reside in a plane that is in a linear orientation and located in a substantially similar plane as at least one of an axle of the vehicle or the frame of the vehicle. In one embodiment, the first container and, optionally, the second container may be horizontally positioned in a plane that is substantially similar to a frame of the vehicle or at least one axle of the vehicle. Furthermore, the one or more containers may be parallel to a ground to which the vehicle travels or drives on. In another embodiment, the first container and, optionally, the second container may be vertically positioned in a plane behind the cabin of the vehicle perpendicular to a ground to which the vehicle travels or drives on.

[0045] In another embodiment, a manifold system is employed with the systems 100 and 102 that includes a driver side manifold and a passenger side manifold. The manifolds (e.g., the passenger side manifold and driver side manifold) each include respective elements such as, but not limited to, a fast-fill port, a transfer valve, a fuel transfer port, among others. Each manifold can further include shut-off valves, internal check valves, inlet fittings, fuel storage fittings, coalescing filter, pressure gage, and the like.

[0046] In another embodiment, a communications component is utilized with a system 100 and/or 102 that provides at least one of user interaction with a system 100 and/or 102 and/or diagnostic information related to the system 100 and/or 102. Additionally, the communications component can provide a display for a back-up camera on the vehicle and/or trailer. The communications component can be physically located inside the vehicle to provide information such as, but not limited to, one or more container pressure, temperature of one or more containers, real time information related to the system, temperature compensation fuel gauge, among others. The communications component may comprise a gauge, a lamp, a light, an LED, a series of lights or LEDs, a CRT, a plasma display, a liquid crystal display, or other data output device chosen with good engineering judgment.

[0047] In an embodiment, a system 100 and/or 102 can leverage at least one Radio Frequency Identification (RFID) tag associated with one or more components (e.g., container, regulator, manifold, fuel line, hose, among others) in which an RFID reader can collect information from the RFID tag in order to verify information associated with the system 100 and/or 102 (e.g., manufacture date, quality control (QC) inspection, shipping date, installation date, installer, critical service dates, historic data, service dates, among others). For instance, RFID tags can be written with identifying data, wherein an RFID reader can receive this identifying data for verification related to safety, tracking, monitoring, quality control, among others. In another embodiment, an RFID component is utilized to scan and program RFID tags with identifying data in which the RFID component utilizes one or more databases to track identifying data to particular elements or components.

[0048] In an embodiment, the cellular multi-protocol RFID reader combines unsurpassed read / write reliability and performance in difficult to read environments with GSM cellular and GPS connectivity for easy deployments at remote or mobile worksites. The reader's advanced design provides backward compatibility with EPCglobal C1G2 (GEN2) certified tags with the maximum allowed 1 watt transmit power, and more than 10X range extension to greater than 100 meters using the Battery Assisted Passive RFID (BAP) protocol extensions in the ISO / IEC 18000- 6:2010 standard. The self contained units can be directly integrated and powered from the installation machine's power source - providing a true mobile solution. This will provide accurate Locating and Asset Management/Tracking of the subject innovation enabled product lines.

[0049] In an embodiment, the system 100 and/or 102 can couple RFID technology with Global Positioning Service (GPS). This coupling can enable operators and/or fleet managers to access location information such as, but not limited to, refueling locations, service center locations, route tracking, among others. In an embodiment, the system 100 and/or 102 can include a settings component that is configured to provide one or more settings or configurations based on particular events, conditions, locations, and the like. For instance, the settings component can utilize a weather setting in which the system 100 and/or 102 performance is modified to account for extreme weather conditions (e.g., hot, cold, dry, high humidity, among others).

[0050] In an embodiment, the system 100 and/or 102 is adapted to integrate with a vehicle. For instance, the system 100 and/or 102 can include a particular design to match with a design of a vehicle to which the CNG system is used. This latter design may include a particular shape, style, look, feel, color, trade dress, brand indicia, or other factors. As described in more detail below, the system 100 and/or 102 can be attached to a frame of a vehicle behind a cabin location with one or more containers in a vertical orientation or underneath a portion of a cabin and along a side of the vehicle or at some other orientation or position. The system 100 and/or 102 can be in a "skin" or housing in which the housing may be metal, metal alloy, composite material, fiberglass, or other material chosen with good engineering judgment and can include a matching style of a design of the cabin and/or overall vehicle. In general, the system 100 and/or 102 can be integrated behind the cabin of the vehicle or underneath a portion of a cabin and along a side of the vehicle or at some other orientation or position such that the system 100 and/or 102 blends with and matches the design of the vehicle.

[0051] In an embodiment, the system 100 and/or 102 includes features that enhance interoperability to a vehicle. For instance, the system 100 and/or 102 can include O-ring face seal connections (ORC) which eliminate metal-to-metal seals and concerns related to torque and assembly time. ORC decrease assembly time based on reliance on compression of an elastomer O-ring while providing leak resistant connections. In another example, a manifold block may eliminate or reduce the need for rigid tubing and may provide for efficient fuel flow without reduction in pressure while also reducing potential number of leak points. The system 100 and/or 102 can implement one or more torque bolt locks (e.g., also referred to as a Huck lock bolt) to prevent loss of clamping force often experienced using fastening hardware.

[0052] In an embodiment, the system 100 and/or 102 employs various safety features. For instance, one or more electric solenoids can be employed in which one or more valves for the one or more containers in the system 100 and/or 102 can be automatically controlled via electric solenoid valves. For instance, in a case of an emergency and manual operation of control valves is unavailable, an electric solenoid valve can provide automatic control (e.g., open, close, etc.) to the one or more containers. In certain embodiments, one or more automatically controlled electric solenoid valves may be arranged in series with one or more manual valves in order to create a valve set in which closure of an automatically controlled electric solenoid valves is sufficient to shut off flow and opening of all the automatically controlled electric solenoid valves in the valve set is necessary to permit flow.

[0053] In an embodiment, the system 100 and/or 102 is assembly line ready and configurable to a vehicle. The system 100 and/or 102 can be a self-contained system that attaches to a portion of a vehicle. In particular, the attachment can be with shock mounts to a frame of the vehicle behind a cabin or to a frame of the vehicle on one or both sides of the vehicle. Attachment to a frame of the vehicle on one or both sides of the vehicle may be with components on one or both sides of the vehicle frame under a portion of a cab of the vehicle. This latter attachment can saddle each side of a frame of the vehicle or can be placed to one side or the other of the vehicle along the frame. Upon attachment to the vehicle, the system 100 and/or 102 can be communicatively coupled to the vehicle via an electric connection and/or a fuel line connection. In another embodiment, the system 100 and/or 102 can include a powder coated exterior adapted to match the style existent on a chosen vehicle. A powder coated exterior may also increase durability. In another embodiment, the system 100 and/or 102 can include one or more components or features fabricated from a composite material, such as, without limitation, fiberglass. Composite materials may be selected to provide desired strength, toughness, and weight.

[0054] In an embodiment, the system 100 and/or 102 can include a temperature sensitive component operatively engaged with a valve for the one or more containers. In some non-limiting embodiments, the temperature sensitive component can be proximate to the one or more containers and may include a wire component encased within a cylinder tubing, wherein the wire component is coupled to a valve for each of the one or more containers. The wire component of the temperature sensitive component disconnects to open the valve at a temperature to release contents of the one or more containers.

A manifold block 610 may be used rather than tubing or other conduit 640 and thereby may reduce or eliminate rigid tubing or other conduit 640. Reducing or eliminating rigid tubing or other conduit 640 may result in more efficient fuel flow without reducing flow pressure while also reducing the number of potential leak points. Without limitation, a fuel module 600 may include an improved regulator 620. In a particular embodiment, the system 100 and 102 can include dual regulators. For instance, dual regulators can be utilized to improve delivery of CNG. In some embodiments regulator 620 may be adapted to fuel either 12L or 9L diesel engines.

[00134] By way of example and not limitation, the first support 1300' can be aligned with a first end of container 200 and the second support can be aligned with a second end of the container 200, where the first end is opposite the second end. In particular, a respective mounting bracket 390 and shock mount 310 can be coupled to the first support 1300'. Additionally, a respective mounting bracket 390 and shock mount 310 can be coupled to the second support 1302'. In a particular embodiment, an additional mounting bracket 390 and shock mount 310 can be coupled to the casing 400' at a location in between the first support 1300' and the second support 1302'.

[00135] It is to be appreciated, as discussed above, that the system 102 can include one or more containers. In a non-limiting embodiment a first container and a second container is illustrated. In another embodiment, the system 100 can include the first side 306 and the second side 308, wherein the first side 306 houses a first container 200 and the second side 308 houses a weight element (e.g., counterweight, a automatically controlled and adjusted weight element, a counterbalance element, among others) to balance the system 102 coupled to the chassis or frame of the vehicle. It is to be appreciated that the weight element size, shape, weight, and other characteristics can be chosen with sound engineering judgment and are intended to be within the scope of the subject innovation.

[00136] It is to be appreciated that the first side 306 and the second side 308 can be a frame for the system 102 that supports one or more containers 200 in a horizontal configuration such that the containers are horizontal in comparison to a surface the vehicle is traveling and/or one or more axles of the vehicle. By way of example and not limitation, the frame for the system 102 can include at least one of the first side 306, the second side 308, the connecting member 330, the casing 400, the shock mount 310, the mounting bracket 390, the support member 1300 and the support member 1302.

[00137] In the specification and claims, reference will be made to a number of terms that have the following meanings. The singular forms "a", "an" and "the" include plural referents unless the context clearly dictates otherwise. Approximating language, as used herein throughout the specification and claims, may be applied to modify a quantitative representation that could permissibly vary without resulting in a change in the basic function to which it is related. Accordingly, a value modified by a term such as "about" is not to be limited to the precise value specified. In some instances, the approximating language may correspond to the precision of an instrument for measuring the value. Moreover, unless specifically stated otherwise, a use of the terms "first," "second," etc., do not denote an order or importance, but rather the terms "first," "second," etc., are used to distinguish one element from another.

[00138] As used herein, the terms "may" and "may be" indicate a possibility of an occurrence within a set of circumstances; a possession of a specified property, characteristic or function; and/or qualify another verb by expressing one or more of an ability, capability, or possibility associated with the qualified verb. Accordingly, usage of "may" and "may be" indicates that a modified term is apparently appropriate, capable, or suitable for an indicated capacity, function, or usage, while taking into account that in some circumstances the modified term may sometimes not be appropriate, capable, or suitable. For example, in some circumstances an event or capacity can be expected, while in other circumstances the event or capacity cannot occur - this distinction is captured by the terms "may" and "may be."

[00139] This written description uses examples to disclose the subject matter, including the best mode, and also to enable one of ordinary skill in the art to practice the invention, including making and using a devices or systems and performing incorporated methods. The patentable scope of the invention is defined by the claims, and may include other examples that occur to one of ordinary skill in the art. Such other examples are intended to be within the scope of the claims if they have structural elements that do not differentiate from the literal language of the claims, or if they include equivalent structural elements with insubstantial differences from the literal language of the claims.
