Early Prediction of CNG Filling Time using Artificial Intelligence for Design Optimization2026-26-0662To be published on 01/16/2026
The CNG fuel system is a critical component in vehicle development and typically includes large-volume gas cylinders (up to 800 liters). As these vehicles often operate over long distances daily, frequent refueling is necessary, making a short gas filling time highly desirable. Currently, CNG filling time is evaluated after prototype development to determine the refueling duration. If the filling time is excessive, design changes to the fuel system are required, leading to significant cost and time penalties and causing delays in the vehicle product development cycle. By integrating AI/ML technology, a mathematical model has been developed based on various influencing parameters. This model will predict CNG gas filling time across all commercial vehicle platforms at the initial Zero design release gateway. This early prediction will enable further optimization to improve gas filling time. The goal of this research work to optimising the filling time for various platform before physical

Fueling Protocols for Light Duty Gaseous Hydrogen Surface VehiclesJ2601_202005 (Current)05/29/2020
SAE J2601 establishes the protocol and process limits for hydrogen fueling of vehicles with total volume capacities greater than or equal to 49.7 L. These process limits (including the fuel delivery temperature, the maximum fuel flow rate, the rate of pressure increase, and the ending pressure) are affected by factors such as ambient temperature, fuel delivery temperature, and initial pressure in the vehicle’s compressed hydrogen storage system. SAE J2601 establishes standard fueling protocols based on either a look-up table approach utilizing a fixed pressure ramp rate, or a formula-based approach utilizing a dynamic pressure ramp rate continuously calculated throughout the fill. Both protocols allow for fueling with communications or without communications. The table-based protocol provides a fixed end-of-fill pressure target, whereas the formula-based protocol calculates the end-of-fill pressure target continuously. For fueling with communications, this standard is to be used in

Highly Efficient Civil Aviation, Now via Operations - AAR and Challenges2018-01-192510/30/2018
Global civil aviation growth at 5+% yearly poses extreme environmental challenges. Advances have appeared gradually through improved aerodynamic shapes, using carbon fibres, and enhanced engines; however, as these technologies mature, direct efficiency advances require increasing effort. Often Passenger convenience is forgotten e.g. the long-range air traffic has developed on hub-spoke basis implying extra feeder flights, transit passenger inconveniences, capacity issues. Efficiency metrics emphasize “Why, How & What”, with an understanding of the range sensitivities, operational concepts and performance goals via the important “X-factor”. For given range, current aircraft are “greener” than previous generations. Medium range aircraft s are always greener than those for short or long ranges. However, currently, the major trend is for the latter: twin-aisle A350, A380, B787, B777X (10+% payload, 40+% fuel to MTOW). Shorter range single-aisle aircraft are “feeders” or newer derivatives

Soy Biodiesel Oxidation at Vehicle Fuel System Temperature: Influence of Aged Fuel on Fresh Fuel Degradation to Simulate Refueling2017-01-080903/28/2017
An experimental study of the effects of partially-oxidized biodiesel fuel on the degradation of fresh fuel was performed. A blend of soybean oil fatty acid methyl esters (FAMEs) in petroleum diesel fuel (30% v:v biodiesel, B30) was aged under accelerated conditions (90°C with aeration). Aging conditions focused on three different degrees of initial oxidation: 1) reduced oxidation stability (Rancimat induction period, IP); 2) high peroxide values (PV); and 3) high total acid number (TAN). Aged B30 fuel was mixed with fresh B30 fuel at two concentrations (10% and 30% m:m) and degradation of the mixtures at the above aging conditions was monitored for IP, PV, TAN, and FAME composition. Greater content of aged fuel carryover (30% m:m) corresponded to stronger effects. Oxidation stability was most adversely affected by high peroxide concentration (Scenario 2), while peroxide content was most reduced for the high TAN scenario (Scenario 3). However, changes in TAN and FAME composition were

Oxidation Stability of Diesel-Biodiesel Blends: Impact of Physical-Chemical Properties Over Ageing into Fuel Injection Systems (FIS) and Storage2016-01-226710/17/2016
The increased use of alternative fuels has been linked to deterioration in performance of fuel injection systems as a result of insoluble deposit formation. Here, the impact of Diesel/biodiesel blends formulation and temperature on the oxidation stability was studied based on total acid number (TAN), density, viscosity and surface tension. We have compared fuel oxidation during storage with fuel oxidation into the fuel injection system (FIS) and determined the most important physical-chemical parameters that could be used to follow fuel oxidation on-board. Based on the results obtained, a satisfactory correlation between storage oxidation and fuel on-board degradation was observed. Biodiesel fuel tends to deteriorate during delivery and storage before refueling. Also, fuel ageing on-board is equivalent to 4-5months of storage which means Biodiesel has impact on fuel injection system with long-term storage/parking after high or high-low alternating load operation.

Testing Particle Counters for Detection of Fuel ContaminationTBMG-2034708/01/2014
Fuel quality assurance is accomplished by conducting periodic fuel sampling for the condition monitoring of aviation fuel by detecting, measuring, and reporting the levels of contaminants in the fuel. Current methods have several drawbacks including operator subjectivity, lack of detailed analysis, limitations in providing reliable data, and the turnaround time needed to get the test results.
Palletized Air to Air Refueling Kit for Medium and Light Military Transport Aircraft2013-01-208909/17/2013
Air to Air refueling (AAR) operations are typically performed with dedicated tanker A/C. Most existing tankers are derived from civil airliners like the A330MRTT from Airbus Military or from military transport A/C with permanent modifications for the tanker role. For being able to refuel in flight some type of receivers like medium and light turboprops, helicopters and certain UAVs, the tanker aircraft should be able to fly at low speeds. For that role medium/small size turboprop military transport aircraft, like the C295 from Airbus Military are ideally suited. This paper proposes a new palletized AAR kit for conversion of a transport A/C into a tanker. The kit includes all the needed air refueling systems, and can be installed on an existing military transport aircraft with rear cargo door ramp without big permanent modifications to the base platform. The kit can also integrate an autonomous electrical system for powering the power-hungry refueling systems with no power demand to the

Understanding of Thermal Characteristics of Fueling Hydrogen High Pressure Tanks and Governing Parameters2013-01-047404/08/2013
For safe and fast refueling hydrogen to fuel cell vehicles (FCVs) at hydrogen refueling stations (HRSs), a refueling protocol is under discussion at SAE J2601 to be a global standard. In order to realize such a standard, we have to estimate the relation between gas temperature and pressure during a refueling and for an accurate estimation we have to correctly understand the thermal characteristics of hydrogen tank. Fast refueling test data has been offered by BMW-Powertech, some test cases have been analyzed by a simulation model developed by Monde et al. It reveals that the hydrogen temperature at the end of refueling does not exceed 85°C for these analyzed cases. The effect of the pressure drop between storage bank and hydrogen tank was negligible on the gas temperature at the end of refueling, although the gas temperature shows different profile depending on the pressure drop. The simulation results of the model in this study were in good agreement with the gas temperature profile

Application of MC Method-Based H2 Fueling2012-01-122304/16/2012
To address challenges related to refueling with compressed hydrogen, a simple, analytical method has been developed that allows a hydrogen station to directly and accurately calculate an end-of-fill temperature in a hydrogen tank and thereby maximize the fill quantity and minimize the refueling time. This is referred to as the MC Fueling Method, where MC represents total heat capacity. The MC Method incorporates a set of thermodynamic parameters for the tank system that are used by the station in a simple analytical equation along with measured values of dispensed hydrogen temperature and pressure at the station. These parameters can be communicated to the hydrogen station either directly from the vehicle or from a database that is accessible by the station. Because the MC Method is based on direct measurements of actual thermodynamic conditions at the station, and quantified thermodynamic behavior of the tank system, highly accurate tank filling results can be achieved. The MC Method

Biodiesel Stability and its Effects on Diesel Fuel Injection Equipment2012-01-086004/16/2012
The effects of biodiesel oxidation stability on diesel fuel injection equipment (FIE) behavior were investigated using newly developed test rig and methodology. On the test rig, biodiesel blend fuels were circulated through a fuel tank and a common rail injection system. Fuel injected from typical diesel injectors was returned into the fuel tank to enhance the speed of fuel degradation. The results showed that injector deposits could be reproduced on a test rig. It was observed that injector body temperature increase accelerates the degradation of fuel and therefore gives earlier FIE failure. Fuel renewal could partially restore the injection quantity after complete failure at low injection pressure, thus showing a potential cleaning effect on injector deposits when refueling a car. Fuel quality was monitored during the rig test to investigate the degradation trends and it was seen that there are two major steps during fuel deterioration: an oxidation followed by an acidification

Adaptive Trajectory Application for Autonomous Aerial Refueling2011-01-263410/18/2011
An outer loop guidance architecture was designed to control autonomous aerial refueling mission from the trail aircraft side. The design utilized bank, yaw rate, velocity and climb rate commands implemented using a previously developed adaptive trajectory concept. The concept was based on position error feedback that was used to control trail aircraft overshoot and tracking about the lead aircraft refueling point. To demonstrate this application, an open loop linear trail aircraft model at a given flight condition was selected. Inner loop control laws were designed using Linear Quadratic Regulator feedback controller and Balanced Deviation theory. The outer loop guidance architecture was then added to implement the application. The performance of the system was then evaluated for a selected position error, and disturbance.
