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

Adaptive Economy Drive Mode Algorithm Development for Fuel Efficient Operation in Light Commercial Vehicle2026-26-0063To be published on 01/16/2026
In Commercial vehicles, during the transit of goods for delivery the vehicle is in laden condition and after delivery it returns in unladen condition. The engine is designed and calibrated to get good drivability in Gross Vehicle Weight (GVW) of the vehicle. When the vehicle is driven at unladen condition or partially laden condition, the vehicle is accelerated very high due to higher torque available from engine, leading to excessive fuel consumption. In some commercial vehicle models, Economy Drive mode option is available, in which the maximum torque delivered by engine is tapered to one level down to achieve better fuel economy. But in GVW condition with Economy Drive mode the driver may not feel the acceleration response and he tend to switch to Power mode. This technical paper describes Adaptive Economy Drive Mode algorithm development which operates with sufficient acceleration using optimum fuel. In Adaptive Economy Drive mode, there are 3 phases.

Misfires Detection in Bi-fuel Engines – A Brief Note2026-26-0120To be published on 01/16/2026
Misfire detection in bi-fuel engines operating on compressed natural gas (CNG) and gasoline mode presents significant challenges due to inherent differences in combustion characteristics: ignition dynamics and fuel properties. Accurate detection is essential for minimizing the emissions, engine performance, and ensuring regulatory compliance. A fundamental parameter in crankshaft speed fluctuation-based misfire detection is segment time selection, which directly influences detection fidelity, false positives, and false negatives. Given CNG’s slower combustion kinetics and delayed flame propagation, it necessitates a delayed segment initiation and an extended segment duration, whereas gasoline characterized by faster combustion, permits earlier segment initiation and a reduced segment duration. Optimal segment timing is determined by analyzing engine roughness, minimizing signal-to-noise ratio (SNR), and eliminating cylinder overlap, while also incorporating flywheel manufacturing

In automotive engineering, understanding driving behavior is crucial for decision on specifications of future system designs. This study introduces an innovative approach to modeling driving behavior using Graph Attention Networks (GATs). By leveraging spatial relationships encoded in H3 indices, we construct a graph-based model that captures dependencies between various vehicle operational parameters and their operational regions using H3 indices. The model utilizes CAN signal features such as speed, fuel efficiency, engine temperature, and categorical identifiers of vehicle type and sub-type. Additionally, regional indices are incorporated to enrich the contextual information. The GAT model processes these heterogeneous features, learning to identify patterns indicative of driving behavior. This approach offers several significant advantages.

Study of Drive Trace Indices and their correlation with CO2 in Chassis Dynamometer testing2026-26-0517To be published on 01/16/2026
With introduction of CAFÉ norms in India, the manufacturers of all M1 Category vehicles (not exceeding 3,500kg GVW) must ascertain that they comply with Annual Corporate average CO2 target as defined in regulation. Moreover, this target will become stricter in different stages in upcoming years. Hence CO2 emissions are becoming one of the major focus parameters during vehicle development. There are various factors that can impact CO2 emissions during measurement in test cycle such as MIDC/WLTC. One such major factor is driving variations. Although speed and time tolerances are provided during the test (as part of AIS 137/AIS 175) limit the variation, even within these tolerances, drive-related effects can be significant contributors to test results variability. Monitoring and control of such variations is important to understand the true fuel economy potential of the vehicle. Drive Trace indices are standardized metrics that can be used to evaluate the driving variations. The aim of

Integrating V2V and V2I Communications for Enhanced Traffic Safety and Efficiency in Connected Vehicular Networks2026-26-0271To be published on 01/16/2026
This paper presents a new approach to improve road safety and traffic flow by combining vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications. Our study focuses on a system that connects vehicles with each other and with traffic signals to share real-time data about speed, position, and road conditions. Using both analytical models and experimental simulations built in MATLAB/Simulink, we developed a system that predicts and advises the optimal speed for vehicles approaching an intersection. In our design, a Green Light Optimized Speed Advisory (GLOSA) feature suggests an ideal speed for drivers so that they can pass through green lights without unnecessary stopping. This not only improves traffic flow but also reduces fuel consumption and lowers the risk of accidents. We validated our system through a series of simulations and real-time traffic scenarios. The results show that our approach can adapt dynamically to changes in vehicle behavior and traffic density

Introducing a new catalyst family in gasoline aftertreatment2026-26-0231To be published on 01/16/2026
This paper is to introduce a new catalyst family in gasoline aftertreatment. Indeed, it has been shown that under certain driving conditions, three-way catalysts produce significant amounts of toxic NH3 and the strong greenhouse gas N2O, which are both very unwanted emissions. In a self-committed approach, OEMs could want to minimize these noxious pollutants, especially if this can be done with no architecture change, namely without additional underfloor catalyst. In this paper we will compare different approaches: regular underfloor TWC, SCR derived from diesel aftertreatment, gasoline dedicated Ammonia Slip Catalyst (ASC) and especially developed novel gasoline Secondary Emission Treatment (SET) catalyst, providing both ammonia abatement and underfloor three-way functionality. The data will show that SCR only reduces NH3 from a passive SCR reaction in a limited amount in the cold start including the need of oxygen presence, namely secondary air introduction. ASC is efficient in cold

Methodology to Accelerate BEV Range Testing Using Shortened Cycle Maintaining High Testing Reliability and Accuracy.2026-26-0444To be published on 01/16/2026
In the era of Electric Vehicles (EVs), range is a critical factor for market success. To mitigate range anxiety, Original Equipment Manufacturers (OEMs) are equipping vehicles with larger battery packs. Unlike internal combustion engine (ICE) vehicles, where fuel economy can be determined with a single legislative cycle run, EVs require a full battery discharge to calculate their range. These tests typically take around 10 hours, and this time increases as battery pack sizes grow. A shortened testing cycle has been developed that reduces the testing time to approximately 4-5 hours, leading to significant savings in time, effort, and cost. The shortened cycle consists of three phases: Dynamic Segment1, Constant Speed, and Dynamic Segment2. Despite variations in battery size and powertrain configurations, the testing duration remains consistent. A key challenge in actual testing is accurately determining the start and end points of Dynamic Segment 2 (DS2), which is an iterative process

Evaluation of Waste Heat Recovery technology in FCEV on different drive-cycles2026-26-0259To be published on 01/16/2026
Growing global warming and the associated climate change have expedited the need for adoption of carbon-neutral technologies. The transportation sector accounts for ~ 25 % of total carbon emissions. Hydrogen (H2) is widely explored as an alternative for decarbonizing the transport sector. The application of H2 through PEM Fuel Cells is one of the options available for the trucking industry, due to their relatively higher efficiency (~50%) and power density. However, at present the cost of an FCEV truck is considerably higher than its diesel equivalent. Hence, new technologies either enabling cost reduction or efficiency improvement for FCEVs are imperative for their widespread adoption. FCEVs have a system efficiency in the range of 40-60% implying that around half of the input energy is lost to the atmosphere as waste heat. However, recapturing this significant amount of low-grade waste heat into useful work is a challenge. This paper discusses the feasibility of waste heat recovery

Analysis of design parameters of fuel cell stack design for vehicle level performance enhancement2026-26-0264To be published on 01/16/2026
The design of the fuel cell stack for enhanced power and voltage characteristics is essential as it impacts the drivability of the vehicles. While many experimental approaches have been explored to improve the performance of the fuel cell stack by refining its design, they are largely limited to trial-and-error based approaches. Hence, the task of identifying the critical parameters affecting the performance of the fuel cell stack becomes tedious. The process is further complicated when many parameters have a counterbalancing impact on the stack performance. To help refine the design process of the fuel cell stack for enhancing the performance, a sensitivity analysis based approach is proposed in this paper in which a mathematical model of the fuel cell stack relating the parameters and stack power, and voltage is used. As a baseline the reliability of the mathematical model is presented first demonstrating its utility for the current study. The parameters used include membrane

Design Solutions for Ice-Induced CNG Filling Failures: Field Issue Resolution through Filter Geometry and Seal Material Reengineering2026-26-0515To be published on 01/16/2026
Compressed Natural Gas (CNG) systems in automotive applications are highly sensitive to fuel quality, especially with respect to moisture content. Field issues were observed where high moisture levels in the CNG led to the formation of ice inside the receptacle during refueling operations. This ice formation obstructed the CNG filling process and adversely impacted the sealing performance of the O-ring, particularly under low-temperature conditions induced by pressure differentials between the storage tank and the filling station. Investigation revealed that the existing tablet-type filter design contributed to moisture entrapment within its wire mesh, exacerbating ice formation within the receptacle. To address this, the filter design was modified from a tablet-type to a cup-type filter, significantly reducing the likelihood of moisture retention and subsequent ice formation.

DPF Passive Regeneration Approach for CEV/TREM-V Off-Highway Applications2026-26-0211To be published on 01/16/2026
With introduction of Diesel Particulate Filter to achieve CEV/TREM V Emission Limits for off-highway segment, requirement of DPF regeneration at defined intervals depending on time of operation and soot loading of DPF. This can be achieved by two methods. First is the frequent regeneration or active regeneration, wherein fuel is injected before DOC (Diesel Oxidation Catalyst) at specific temperature to burn the soot in the DPF. The second method is the continuous or passive regeneration, where soot is burnt based on NO2. DPF frequent regeneration (Active Regeneration) requires soot load estimation in DPF over entire engine operation range as well as vehicle operation in different climatic conditions. Frequent regeneration leads to oil dilution and penalty in the fuel consumption. More frequent regeneration promotes the chemical aging of DOC , leading to the poor performance of DOC which results in deteriorated performance of SCR(Selective Catalytic Reduction) situated at downstream of
