Reverse Engineering and Digital Twins in Powertrain Design: Enhancing Performance and Sustainability2026-26-0065To be published on 01/16/2026
This study explores the application of reverse engineering (RE) and digital twin (DT) technology in the design and optimization of advanced powertrain systems. Traditional approaches to powertrain development often rely on legacy designs with limited adaptability to modern efficiency and emission standards. In this work, we present a methodology combining 3D scanning, computational modeling, and machine learning to reconstruct, analyze, and enhance internal combustion engines (ICEs) and electric vehicle (EV) drivetrains. By digitizing physical components through RE, we generate high-fidelity DT models that enable virtual testing, performance prediction, and iterative improvement without costly physical prototyping. Key innovations include a novel mesh refinement technique for scanned geometries and a hybrid simulation framework integrating finite element analysis (FEA) and multi-body dynamics (MBD). Our case study demonstrates a 12% increase in thermal efficiency for a retrofitted ICE

An Experimental Approach towards Sustainable Solution for Material Recycling of ELV Plastic Bumpers and EV Batteries2024-26-016401/16/2024
The automotive industry in India generates a significant amount of waste and pollution through end-of-life vehicles (ELVs). This paper addresses the current state and challenges of ELV recycling in India and presents a sustainable solution for recycling waste bumpers and electric vehicle (EV) batteries. With the Indian domestic passenger vehicle sales reaching 3.9 million units in 2022-2023, the need for effective recycling measures is becoming increasingly critical. The study estimates that in FY 2023-24 alone, the Indian automotive passenger vehicle industry will produce approximately 2.9 million tons of scrap, with 0.1 million tons attributed to plastic materials. Considering the 15-year end-of-life period for vehicles and the historical sales figures, this scrap generation is expected to grow exponentially each year. To address this issue, the paper proposes a comprehensive recycling approach that focuses on two key aspects: plastic recycling and the recovery of precious metals

Additive-manufacturing system providers still see technical and throughput challenges, but significant developments and market inroads will be made in 2020. The global 3D-printing metals market was estimated to be US $774 million in 2019, according to a recent research report by MarketsandMarkets. The research company projects the market to reach more than US $3.1 billion by 2024, at a compound annual growth rate of 32.5% from 2019 to 2024. Driving this growth is the increasing demand for 3D-printed metals from aerospace & defense and automotive end-use industries, low manufacturing cost, and reduction in lead times, the report says. Another key factor that will influence growth is quality assurance: metal additive manufacturing (AM) machines must be able to consistently produce a high level of repeatable quality parts.

An Institutional Framework to Address End-of-Life Vehicle Recycling Problem in India2017-26-017901/10/2017
The Indian Economy is becoming significant in the late years. There will be more middle class individuals in the coming years having higher purchasing power, bringing about sharp increment in the ownership of vehicles. The quantity of End-of-Life Vehicles (ELVs) in 2015 is evaluated at 8.7 million and by 2025, this figure is assessed to ascend to 21.8 million. Car breaking yards' ELV recycling practices result in inadequate resource recovery and various forms of pollution. 75-80% of the ELV constitutes of metal and recycled due to its economic benefits. The rest of the 25-30% comprises of plastics, rubber, glass and operating fluids which are mostly disposed off in land or water. Existing international literature has analyzed ELV recycling and remanufacturing practices in India as separate topics. By adopting Circular Economy practices such as 3R (spare parts reuse, component remanufacturing and materials recycling), the institutional framework proposed in this paper considers both ELV
