Abstract
Provided is a compressed natural gas (CNG) fuel system that can include a frame and at least one container. The frame can include a first side and a second side, with each side being configured to partly define a portion of an interior space. The at least one container can be configured to house or contain CNG and can be engaged to and partly encased by the frame. The at least one container can be partly located within the interior space of at least one of the first side or the second side. The frame assembly can be engaged to a chassis of a vehicle such that the at least one container is located either at least partially underneath a cab of the vehicle or at least partially behind a cab of the vehicle.
Claims20
A fuel delivery system intended to deliver fuel to a vehicle engine of a vehicle having a cabin, comprising:
- a first container having a cylindrical shape with a length, a diameter, and a first end opposite a second end in which the first end includes a first valve opening;
- a second container having a cylindrical shape with a length, a diameter, and a first end opposite a second end in which the first end includes a second valve opening;
- a conduit for a gas flow between at least two of the first container, the second container, the first valve opening, the second valve opening, and the vehicle engine;
- a frame that defines an interior space, the frame supports the first container and the second container within the defined interior space;
- the frame is engaged to a chassis of the vehicle at a location on the chassis such that the first container and the second container are located rearward of the cabin of the vehicle;
- the frame shrouds a manifold engaged to the frame within the defined interior space;
- and
- an access door that is configured to be opened or closed to gain access to the manifold.
