Design & Optimization of CV shaft system to address powertrain induced NVH issues2026-26-0336To be published on 01/16/2026
The automotive industry is a crucial sector that plays a significant role globally. Government policies have a profound impact on this automotive industry in defining the regulatory standards and emission controls. Such regulations incentivized automakers to invest in research and development complying those standards towards reduction of vehicle emission which intern result in higher torsional vibrations and excitations amplitudes. To address the rising NVH related concerns in driveline system. Drive shafts (CV shafts) is an important component in power-train system in vehicle. Drive shaft’s main purpose to transfer torque from engines to wheels at multiple speeds with different articulation angles. The roughness generated by the engine follows a transfer path from engine to transaxle and transaxle to half shafts in monocoque vehicles which generates discomfort to the drivers whenever the vehicle is driven. The roughness can also be addressed by proper design of driveshaft stiffness

Regulatory Divergence in Autonomous Vehicle Deployment A Comparative Study of the US, EU, and China2026-26-0243To be published on 01/16/2026
Autonomous vehicle (AV) regulatory frameworks vary significantly across global regions, with the United States, European Union (EU), and China exemplifying distinct approaches. The US adopts a decentralized model, allowing state-level regulation with federal guidance, fostering testing and commercial deployment of Level 4 automation. The EU enforces a harmonized, safety-focused framework under legislation like Regulation (EU) 2019/2144 and (EU) 2022/1426, emphasizing structured validation within defined operational domains. China employs a centralized regulatory hierarchy, integrating national standards with localized pilot programs and connected infrastructure. While the US leads in commercial deployment and China advances through coordinated efforts, the EU’s cautious framework is often perceived as a barrier to rapid AV adoption. This paper critically analyzes these regulatory models, emphasizing the need for a robust, harmonized framework that ensures safety and public trust

Electrifying the Giants: Green mobility solution for M&HCVs in India.2024-26-013101/16/2024
Diesel operated Medium and Heavy Commercial Vehicles (M&HCV) account for nearly 70% of all road transportation in India which is expected to quadruple, from 4 million in 2022 to roughly 17 million trucks by 2050. Despite comprising a mere 5% of total vehicle fleet, they consume nearly 57% of fossil fuel used by the transport sector and responsible for 71% ,74% and 55% of CO2 ,PM and NOx emissions respectively. This necessities the transition of M&HCV into green mobility solution. Furthermore, smaller vehicles like 2W, 3W, 4 wheeler like cars and buses are adopting EV technology at a faster pace coupled with incentivization through government policies like FAME-I, FAME-II etc., advocates an immediate intervention on electrification of M&HCVs to multifold the impact. This paper suggests a collaborative approach amongst M&HCV manufactures and government agencies to realize the transition while integrating the benefits of reduced emissions, lower operating costs, quieter operation

MULTI-ENVIRONMENT ACCELERATED DURABILITY TEST FOR EXHAUST SYSTEM FLANGE JOINTS2021-26-047209/22/2021
Accelerated testing is vital to meet stringent project timelines and is a key consideration for developing new testing methodology. Specifically, durability testing is one of the key fields of interest to deal with all aspects. Fatigue with exposure to multiple environments is a major cause of exhaust system flange joint failure. Physical verification of increased design life expectancy, demands longer testing time, while shorter time to market is main differentiator for competitiveness. Government policy induced timeline pressures added to the need of accelerated tests. The methodology described in this paper embraces these aspects to ensure a quicker flange joint testing, with due consideration to environmental impact. Until the BSVI norms, marginal leakage through the system joints was usual and acceptable. Stringent emission norms demand ‘near-zero’ leakage from exhaust systems. The system joints essentially being the most probable leakage zones, became the focus area

Potentials and Challenges of a Brake Particle Emission Collecting System2020-01-163510/05/2020
Brake particle emissions as a part of non-exhaust emissions are becoming more and more relevant, various international research activities can be stated. Also from the legislation side, first hints are given in regards of possible regulations. One possible approach for the reduction of brake particle emissions deals with the collection of those particles close to the foundation brake. The presented paper will follow such an approach and give some insights. In a first step, the technical layout is described for bench and vehicle testing. While for bench testing a PMP-like style of the setup could be chosen, the vehicle test setup is oriented on conventional wheel dust measurements. Hence, presented results of laboratory testing are dealing with PN and PM measurements. Also the impact on particle size distribution is discussed. It can be stated, that the particle collecting system is able to improve PN and PM emissions. Additionally, ultra-fine particles are almost eliminated. The

The Particle Number Counter as a “Black Box” - A Novel Approach to a Universal Particle Number Calibration Standard for Automotive Exhaust2020-01-219509/15/2020
The reduction of vehicle exhaust particle emissions is a success story of European legislation. Various particle number (PN) counters and calibration procedures serve as tools to enforce PN emission limits during vehicle type approval (VTA) or periodical technical inspection (PTI) of in-use vehicles. Although all devices and procedures apply to the same PN-metric, they were developed for different purposes, by different stakeholder groups and for different target costs and technical scopes. Furthermore, their calibration procedures were independently defined by different stakeholder communities. This frequently leads to comparability and interpretation issues. Systematic differences of stationary and mobile PN counters (PN-PEMS) are well-documented. New, low-cost PTI PN counters will aggravate this problem. Today, tools to directly compare different instruments are scarce. This is complicated by a dominance of proprietary, undisclosed or only partially disclosed manufacturer

EDITORIAL: Kill the EV tax credit by 202519AUTP03_0603/01/2019
What role should government play in shifting consumer demand to cleaner forms of mobility? For the past decade, federal tax credits of up to $7,500 have helped woo a miniscule percentage of U.S. buyers into the plug-in electric-vehicle (EV) fold. The tax credits were key to the Obama administration's plan to have 1 million EVs on the road by 2015. That goal wasn't achieved until 2018, when U.S. market share of EVs reached a heady 2.1%-up from 0.62% in 2013.

CFD Investigation of the Impact of Electrical Heating on the Light-off of a Diesel Oxidation Catalyst2018-01-096104/03/2018
In the last years, as a response to the more and more restrictive emission legislation, new devices (SRC, DOC, NOx-trap, DPF) have been progressively introduced as standard components of modern after-treatment system for Diesel engines. In addition, the adoption of electrical heating is nowadays regarded with interest as an effective solution to promote the light-off of the catalyst at low temperature, especially at the start-up of the engine and during the low load operation of the engine typical of the urban drive. In this work, a state-of-the-art 48 V electrical heated catalyst is considered, in order to investigate its effect in increasing the abatement efficiency of a standard DOC. The electrical heating device considered is based on a metallic support, arranged in a spiral layout, and it is heated by the Joule effect due to the passage of the electrical current. As a result of the spiral arrangement, the distribution of the heat source on the heating section is not uniform

Objective Method to Quantify Ecological Toxicity between Friction Materials2017-01-249509/17/2017
California and Washington recently passed legislation to limit certain constituents in brake pad friction materials. As part of the California (CA) legislation enacted in 2010, brake pad manufacturers need to perform an alternative assessment to identify potentially safer environmental and toxicological choices for future friction material production. Copper, chromium VI-salts, lead, cadmium, mercury, and other compounds have been identified as potentially unsafe to the environment. This paper contains the methodology behind an objective and comprehensive alternative assessment to quantify the ecological impact of friction materials. Utilizing raw material specific Chemical Abstracts Service (CAS) numbers and their associated toxicological reference values (TRVs), this newly defined method estimates the total toxicological impact of finished friction materials on both the environment and on a human carcinogenic level to allow the manufacturer to screen greener alternatives.

Technology Evaluation for Two Wheeler Based Personal Mobility in Emerging Markets beyond 20202016-32-007411/08/2016
Personal mobility is evolving in the emerging markets, where the primary need for transportation is met with two wheelers. This reflects on the annual production volumes, which is forecasted to reach 160 million units by 2021[1]. Around 28% of this volume belong to electric two wheelers from China and the remaining are predominantly Internal Combustion Engines (ICE). With the regulators across the globe planning to enforce stricter emission norms in order to improve the air quality and owing to similar demand from the end customers, there is a need for technology to evolve towards harnessing the best energy efficiency using multiple technologies/architectures. However, considering that the majority of two wheelers are used by a population which is cost sensitive, it is imperative that efficient topologies need to be made available at affordable costs. The authors attempt to decipher this need for personal mobility coupled with the stringent regulations. This includes an effort to

A Droplet Size Investigation and Comparison Using a Novel Biomimetic Flash-Boiling Injector for AdBlue Injections2016-01-221110/17/2016
Increased research is being driven by the automotive industry facing challenges, requiring to comply with both current and future emissions legislation, and to lower the fuel consumption. The reason for this legislation is to restrict the harmful pollution which every year causes 3.3 million premature deaths worldwide [1]. One factor that causes this pollution is NOx emissions. NOx emission legislation has been reduced from 8 g/kWh (Euro I) down to 0.4 g/kWh (Euro VI) and recently new legislation for ammonia slip which increase the challenge of exhaust aftertreatment with a SCR system. In order to achieve a good NOx conversion together with a low slip of ammonia, small droplets of Urea solution needs to be injected which can be rapidly evaporated and mixed into the flow of exhaust gases. In most of today's solutions this process is enhanced with flow restricting mixers or longer path lengths but if these can be removed and shortened the flow losses can be reduced, leading to higher

NOx-Conversion and Activation Temperature of a SCR-Catalyst Whilst Using a Novel Biomimetic Flash-Boiling AdBlue Injector on a LD Engine2016-01-221210/17/2016
Yearly 3.3 million premature deaths occur worldwide due to air pollution and NOx pollution counts for nearly one seventh of those [1]. This makes exhaust after-treatment a very important research and has caused the permitted emission levels for NOx to decrease to very low levels, for EURO 6 only 0.4 g/kWh. Recently new legislation on ammonia slip with a limit of 10 ppm NH3 has been added [2], which makes the SCR-technology more challenging. This technology injects small droplets of an aqueous Urea solution into the stream of exhaust gases and through a catalytic reaction within the SCR-catalyst, NOx is converted into Nitrogen and Water. To enable the catalytic reaction the water content in the Urea solution needs to be evaporated and the ammonia molecules need to have sufficient time to mix with the gases prior to the catalyst. The μMist® platform technology, inspired by nature, uses heat in order to increase the fluid temperature above the required saturation temperature within its

New Developments of an On-Vehicle Brake Pad Waste Collection System2016-01-194909/18/2016
The design of a braking system involves a delicate balance between the friction pair, the disc and pad, where the pad is a complex blend of constituents to provide predictable characteristics, typically, a known and consistent friction level. In its base form the brake has to absorb the vehicle kinetic energy by converting it into heat. This heat absorption by the friction pair can result in chemical and physical interactions with the release of debris about which we know little. Other than environmental concerns, brake dust causes unnecessary problems with wear, thermal gradients (hot banding) and NVH. This paper is concerned with the removal and collection of brake debris from the friction interface - the debris being regarded as solids and airborne particles, the latter less than 10μm in size. The test procedure consisted of a Burnish program followed by 8 different drive cycles. The overall effects of debris removal is then reported for each test. It will be shown that, by careful

Overview on ANVC Systems and the Future with Smart Embedded Solutions2015-01-221506/15/2015
How to decrease noise and vibration exposure has been of interest for many years. Empirical data have indicated that too high dose values can create multiple problems to a human body - often severe. Some years back, the European Machinery Directive has increased the responsibility for manufacturers and employers to make sure limits are complying with legislation. Classical technology often consists of passive solutions aiming at trying to cut back on noise and vibration levels. For low frequency, these methods are often lacking the needed performance especially if weight should be considered at the same time.

The demonstration results indicate that an integral city readiness system is required in the promotion of electric vehicles, including the government policies, charging infrastructure, after-sales service, business models and consumer awareness. Through the analysis of related literature and summary reports from 25 demonstration cities, a partial least squares (PLS) path model with 5 major factors and 13 observation indicators was developed to assess the city readiness of electric vehicle adoption. The 5 factors consist of government policies and investment, charging infrastructure construction and operation, business models and maintenance service system, consumer awareness education, operation scope and environmental benefits. Based on the PLS results, 25 cities are classified into 6 groups with the clustering analysis model. The assessment results show

A New and Effective Approach for Knowledge Sharing among Indian Automotive Industry2015-26-007301/14/2015
Access to Knowledge resources around the world demands special skills and calls for judicious investments. Networking is an effective tool and building networks through consortia approach is dire need of the hour. Although this approach has been used in academia, its application in industry, especially among corporate entities, is rare. This paper describes in brief an optimised way to access databases, subscriptions & memberships of different technical societies from global platforms for research & progress of Indian automotive industry. It is imperative for Indian automotive industry to enhance and strengthen its knowledge resource base, particularly in product development and manufacturing domains. This will enable the industry to achieve its mission -“AMP-2016” of becoming a hub for global auto industry. Instead of “compete and grow,” an approach of “collaborate and grow” is thought of. It is proposed to have a knowledge-centric Initiative for Indian Automotive Industry namely The

A Methodology for the Derivation of Movement-and Load Spectra for Energy-Efficiency Test Cycles of Heavy Equipment Vehicles2014-01-235709/30/2014
As a result of the Kyoto Protocol [1], the European Union's legislation demands higher saving rates for the total energy consumption of technical equipment. Heavy Equipment, such as construction- and agricultural machines, contributes over 80% of the total off-road diesel fuel consumption in Germany per annum. It is therefore necessary to provide helpful solutions in order to reach this ambitious aim. The German Federal Ministry of Education and Research cooperates with machine manufacturers, component suppliers and research institutes in the area of heavy equipment. Under the project name TEAM [2] a three year project has been started, which is focused on the development and integration of new propulsion and steering systems for heavy equipment. One task within the project is finding an appropriate way of evaluating the energy efficiency of the enhanced machines, after the powertrain modifications have been applied to it. The wide range of applicability, as well as the existence of

Vehicle-Based Driver Interlocks: After 50 Years of Research, can we now Design an On-Board, Real-Time System to Detect Abnormal Driving Behavior?2014-01-027504/01/2014
In its simplest form, an interlock is a device, installed in a vehicle, that monitors the safety of the vehicle and its occupants, decides whether the vehicle or its occupants are in danger and warns the occupants, or influences the operation of the vehicle. The first interlocks were designed to detect alcohol intoxicated drivers. Three categories of performance interlocks can be identified: Type I interlocks sense physiological parameters of the driver (e.g. alcohol content of alveolar air) determine the driver's level of intoxication and, after comparing this level with a criterion level (e.g. the legal limit for driving), decide whether or not the vehicle should be operated. Type II interlocks measure the behaviour of the driver with cockpit-mounted equipment (e.g. eye movement monitors) or on driving-related tasks and compare this behaviour with established norms. Types III interlocks measure driving performance directly and compare the measured values with performance norms. The

Development of Lens Condition Diagnosis for Lane Departure Warning by Using Outside Camera2014-01-016704/01/2014
Driver safety continues to be improved by advances in active safety technologies. One important example is Lane Departure Warning (LDW). European regulators soon will require LDW in big cars to reduce traffic accidents and New Car Assessment Programs in various countries will include LDW in a few years. Our focus is on rear cameras as sensing devices to recognize lane markers. Rear cameras are the most prevalent cameras for outside monitoring, and new Kids and Cars legislation will make them obligatory in the United States from 2014. As an affordable sensing system, we envision a rear camera which will function both as a rear-view monitoring device for drivers and as an LDW sensing device. However, there is a great difficulty involved in using the rear camera: water-droplets and dirt are directly attached to the lens surface, creating bad lens condition. The purpose of this study is to improve the durability of lane recognition systems when water-droplets and dirt are deposited on the

An Approach to Develop Energy Efficient Operation Strategies and Derivation of Requirements for Vehicle Subsystems Using the Vehicle Air Conditioning System as an Example2013-01-056804/08/2013
Rising oil prices and increasing strict emission legislation force vehicle manufacturers to reduce fuel consumption of future vehicles. In order to meet this target, the process of converting fuel into useable energy and the use of this energy by the different energy-consuming vehicle's subsystems have to be examined. Vehicles' subsystems consist of energy-supplying, energy-consuming, and in some cases energy-storing components. Due to the high complexity of these systems and their interaction, optimization of their energy efficiency is a challenging task. By introducing individual operational strategies for each subsystem, it is possible to increase the energy efficiency for a specific function. To further improve the vehicle's overall energy efficiency, holistic control strategies are introduced that distribute the energy between the subsystems intelligently. To exhaust the whole potential of a holistic control a certain number of degrees of freedom between energy supply and

Future Gasoline Engine Technology and the Effect on Thermal Management and Real World Fuel Consumption2013-01-027104/08/2013
Emissions legislation, fleet CO₂ targets and customer demands are driving the requirements for reducing fuel consumption. This is being achieved in the gasoline market in the near term through the adoption of engine downsizing. In order to reduce fuel consumption further and in the wider real-world operating region complimentary technologies are being investigated and applied to an extreme downsized engine. In this paper future gasoline engine technologies are applied and experimentally assessed in terms of fuel consumption improvement whilst the impact of subsequent loadings on the thermal management system have been simulated, both over drive cycle and using real-world drive data.
