Embodiment Construction

[0018] The following description relates to systems and methods for conformal fuel tanks. Conformal fuel tanks can be shaped to fit to vehicles such as Figure 1A and Figure 1B in the available packaging space of the alternative fuel vehicle shown). Figure 1C An exemplary arrangement of conformal fuel tanks in a vehicle is shown. Conformal fuel tanks can utilize a variety of packaging techniques that can reduce the profile of the fuel tank. Fuel stored in fuel tanks may include various components having natural gas, which may be stored as compressed natural gas (CNG) or as an adsorbed natural gas process. Figure 2A and Figure 2B An example of a conformal fuel tank is shown, where the conformal fuel tank deviates from previous examples of fuel tank shapes (eg, cylindrical, etc.). image 3 An example of a conformal fuel tank with split inlet flow is shown. The split inlet flow conformal fuel tank may be configured to increase the fill rate of the conformal tank while al...

Abstract

The present disclosure provides methods and systems for a conformal fuel tank. Filling methods and systems are provided for a conformable fuel tank. In one example, a system comprises an active thermal management arrangement for the conformable fuel tank. The active thermal management arrangement comprises one or more recirculation passage for mixing hot fuel distal to an inlet port of the conformable fuel tank with cool incoming fuel flowing to the inlet port.

Description

technical field [0001] This specification generally relates to filling conformal fuel tanks. Background technique [0002] Especially in automotive applications, alternatives to petroleum-based fuels are becoming more and more required to reduce greenhouse gas emissions. One hurdle slowing the transition from petroleum fuels to alternative fuels such as hydrogen or natural gas may include the containers in which they are stored. Due to the fuel's lower energy density, the containers for these alternative fuels are larger than petroleum fuel tanks and include thick walls to hold high-pressure hydrogen and natural gas, which can increase material costs and increase packaging constraints. Furthermore, reducing the overall volume of the fuel tank may not be desirable as this may reduce fuel mileage, resulting in increased fuel tank refill times, which may be cumbersome to the vehicle operator. [0003] Other attempts to address the volumetric challenges of alternative fuel sto...
