Calculation of Airflow through the Air Cycle Technology’s Turboexpander and Its Effects on a Diesel Engine—Part I2025-01-50233/31/2025
Abstract Amidst escalating climate change, the sustainability of internal combustion engine (ICE) vehicles, particularly in heavy transport, remains a critical challenge. Despite emission reductions from 1990 to 2020, ICEs, particularly diesel engines in Europe, continue to pose environmental challenges, notably in nitrogen oxide (NOx) emissions. This study proposes a novel solution to address the problem of NOx emissions by incorporating Air Cycle Technology’s (ACT) turboexpander into diesel engines. Acting as a second-stage compressor, intercooler, and expander, the turboexpander aims to lower intake air temperature, thereby mitigating NOx formation. The study utilizes a 4.4-l JCB-TCA-74 turbocharged diesel engine retrofitted with the ACT turboexpander as the experimental platform. The methodology involves using empirical formulae to calculate the key parameters of engine airflow for a standard turbocharged diesel engine followed by repeating the calculations for the same engine

Dynamic Mechanical and Thermal Properties of Polymer-Coated Jute Fibers for Enhanced Automotive Parts2024-01-50192/12/2024
Automobile parts often require materials that offer high strength and durability. With the continuous push for environmentally friendly solutions, natural fibers such as jute have emerged as a potential alternative for synthetic fibers in automobile components. In this study, we aim to enhance the properties of jute fibers by coating them with different polymers and assessing their suitability for automotive applications. We treated jute fibers with various polymers—low-density polyethylene, polyester, and araldite epoxy. The performance of these treated fibers was compared using fiber tensile experimentation, differential calorimetry, and dynamic mechanical evaluation. Our findings reveal that the treated jute fibers exhibit a tensile strength of 598 MPa. However, when coated with polymers, there’s a variance in strength: polyethylene (263 MPa), polyester (191 MPa), and epoxy (281 MPa). Among these, epoxy-coated fibers displayed the least tensile strength, while polyethylene-coated

Data driven decisions to calculate CO2 emission for materials derived from estimated vehicle weight2024-26-01591/16/2024
Change in the gross weight of the car due to change in Special Accessories (SA)/parts/different materials can drastically alter the overall CO2 emission readings. Each carline has multiple variants offered to the customers. Each variant additionally has different code rules associated with them further increasing the customizability. This requires a system to predict the estimated gross weight of the cars to calculate the CO2 emission accurately. Carlines, which are already in production phase, have certified weights associated with them. For each variant of the car, there is a specific weight threshold, which governs the emission certification of it. However, carlines, which are in development phase, have yet to certify for CO2 emission. This makes it very difficult to identify customizability options for development variants. Any change in the part/accessory can make the variant exceed the weight threshold, thus, making it difficult to offer alternatives. The idea is to help the

Optimization of Charging Infrastructure for Fleet Customers2024-26-00921/16/2024
In a rush to move towards a sustainable future, the number of electric vehicles has risen significantly in recent years. With this, the need for power to charge those vehicles has also increased. In any electric vehicle fleet location, there could be a large number of vehicles with different arrival and departure times and energy requirements, which might vary every day. Depending on the geographical location, the available solar energy might differ. The electricity costs might change on an hourly basis. This in total can affect the charging costs. In addition, a non-optimal sizing of the energy components could result in an under-sized system, where the energy demands are not met, or it could result in an over-sized system, where the owner has to invest more than required. Based on all the information related to vehicle charging load, electricity charges, energy intensity profile of renewable energy generation like solar and wind, an optimal size of components, operational cost, and

Design and Optimization of Air intake and Cooling System for Commercial Fuel Cell Electric Vehicles2024-26-01781/16/2024
There is need of the hour to reduce greenhouse gases and become carbon neutral. Global warming and the increase in pollution are big threats to humankind. The Paris Agreement is a major step towards reducing pollution and greenhouse gases. To improve the situation, hydrogen fuel cell electric vehicle is a promising technology that enables zero emissions, zero greenhouse gas generation and high efficiency with superior performance for long-range applications as compared to other green technologies. Although it is a promising and beneficial technology, there is limited information available in the public domain about fuel cell technology and its accessories. Air intake and cooling system’s proper functioning is very important for proper fuel cell functioning. Incoming air to the fuel cell stack needs to be processed by cleaning, humidifying, cooling or heating. If the incoming air isn't clean, it will deteriorate the fuel cell's performance; it may get blocked, or even damaged. Similarly

Electrifying the Giants: Green mobility solution for M&HCVs in India.2024-26-01311/16/2024
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.

Methodology development for E-Axle NVH performance evaluation through virtual simulation2024-26-01201/16/2024
Demand for electrically driven vehicles has increased significantly in recent years, due to its subsidized rate, economical operation and environmentally friendly features. If discussed about India, the sales have increased by 174% in a single year. This drastic jump in sales has encouraged the current automobile manufacturers to come up with more and more electric-driven vehicle platforms in a crunch time frame. And to fulfill these requirements, manufacturers have to work a lot to introduce new technologies like E-axle, which can be space effective, less expensive and easy to assemble. But the introduction of such new technologies brings an even bigger requirement for new validation methodologies, and in the case of electric vehicles (EV) where the development time has been very less, as brought a bigger challenge of more dependency on virtual simulation. As the operational procedure of E-axles is completely different from the conventional axles, the loads that are coming will also
