Characterization and Durability of Mold-In-Color Engineering Plastics

Mahindra & Mahindra, Ltd.-Sandeep Kumar Shukla
  • Technical Paper
  • 2019-28-2542
To be published on 2019-11-21 by SAE International in United States
Plastics are prone to photo oxidative and thermal oxidative degradation under usage conditions due to their chemical nature. From sustainability and cost standpoint, there is an increasing focus on Mold-In-Color (MIC) plastic materials. Simultaneously customer’s expectations on the perceived quality of these MIC parts has been increasing with attractive color and glossy appearance. A study was conducted to analyze the product quality and durability aspects over a prolonged exposure to accelerated weathering condition. Material selected for this study were injection molded specimens of ABS and PC/ABS used in automotive passenger vehicles. Comparative analysis was conducted before and after weathering exposure at defined intervals by using the various tools like Fourier Transform infra-red spectrometer (FTIR), thermogravimetric analyzer (TGA) and universal testing machine (UTM), Izod impact tester, dynamic mechanical analyzer (DMA) to understand the impact on their chemical and mechanical properties. This study will be useful in understanding material behavior, durability, performance and product quality.

To be published on 2019-11-21 by SAE International in United States
OBJECTIVE: Climate change is primary driver in the current discussions on CO2 reduction in the automotive industry. Current Type approval emissions tests (BS III, BS IV) covers only tailpipe emissions, however the emissions produced in upstream and downstream processes (e.g. Raw material sourcing, manufacturing, transportation, vehicle usage, recycle phases) are not considered in the evaluation. The objective of this project is to assess the environmental impact of the product considering all stages of the life cycle, understand the real opportunities to reduce environmental impact across the product life cycle. METHODOLOGY: As a part of environmental sustainability journey in business value chain, Life-cycle assessment (LCA) technique helps to understand the environmental impact categories. To measure overall impact, a cradle to grave approach helps to assess entire life cycle impact throughout various stages. LCA is a technique to assess environmental impacts associated with all the stages of a product's life from raw material extraction through materials processing, manufacture, distribution, use, repair & maintenance, disposal or recycling. A study was conducted on a passenger vehicle for life cycle…

Prototype Design of a Small Scale Thermionic Energy Generator for Waste Heat Recovery in Hybrid Electric Vehicle

BSDU-Kantaprasad Kodihal, Ankur Sagar
  • Technical Paper
  • 2019-28-0027
To be published on 2019-10-11 by SAE International in United States
Sustainable energy solution for hybrid electric vehicles is an important area of research. Mobility and its ease is therefore being an essential component of development. Automotive technology is an area where methods are explored in recent times to provide sustainable solution for reduction of fuel consumption and carbon emissions by switching to hybrid technology and electric vehicles where regeneration of energy plays an important role. At present the research is focused on achieving methods of solid state conversion of heat into electricity but it is limited to thermoelectric methods which has lower conversion efficiency. A comparative analysis of the direct energy convertors shows that thermionic energy conversion stands better with a higher conversion efficiency. Very close and non-contact type of electrode spacing having electrical insulation provided with vacuum or inert gas environment is the basic requirement while designing any thermionic energy generator. Identifying these key research challenges, this article discusses the design of a prototype small scale thermionic generator. The paper hence explores a platform for conducting experimental research on solid state thermionic conversion, space…

Development and Testing of Electric Microcar for Indian Cities

VNR VJIET-Amjad Shaik, Srinivasa Rao Talluri, Raju Tappa, Ramu Ratlavath
  • Technical Paper
  • 2019-28-0008
To be published on 2019-10-11 by SAE International in United States
Population growth, rapid urbanisation and compounding effects of adding personal vehicles have resulted in increasing the urban air pollution in major Indian cities. Apart from the rising concerns about the urban air pollution, the increasing traffic and lack of parking space difficulties are promoting energy efficient small vehicles. Hence, there is a need to develop a new environmental friendly microcar that relatively affordable and easily manoeuvrable in bigger cities. Electric microcar is one of the most promising options to improve the near term sustainability for personal transportation in cities. This paper mainly presents the development of two seater electric microcar suitable for city driving requirements followed by road test. A mathematical modelling with reference to the urban cycle (Part-one) of modified Indian driving cycle (MIDC) is also carried out for the evaluation of energy and power requirements of electric microcar. The developed electric microcar has been tested on road with the help of the MIDC simulator kit. Results revealed that the developed prototype has demonstrated about 50 km range after one full charge.

SEMS for Individual Trip Reports and Long-Time Measurement

Horiba Europe GmbH-Frank Heepen, Weilin Yu
Published 2019-04-02 by SAE International in United States
There is an increasing need to understand the discrepancy between the real-world driving emissions and the emissions determined from type approval in a laboratory. Currently all modern passenger cars and trucks in Europe must undergo an on-road driving emissions test with portable emissions measurement systems (PEMS). Due to the large volume and big operational effort the currently used PEMS has however the constraint for monitoring the emissions of a vehicle within a limited time. To cover as many real-world driving conditions as possible, an online measurement system with automatic functions in data taking, data transferring and data analysis is needed.A Smart Emissions Measurement System (SEMS) was developed by TNO to derive robust and reliable emission factors, this system provides a simple and easy-to-use emissions monitoring solution. Since 2012, this automotive sensor-based system and toolbox has been continuously developed and validated, through numerous measurements of emissions from light duty vehicles (LDV), heavy duty vehicles (HDV) and non-road mobile machinery (NRMM).HORIBA and TNO are collaborating on the industrialization and large-scale deployment of SEMS, enabling new possibilities for…

Ecosystem Feasibility and Sustainability of Aluminium - Air Battery Powered Electric Vehicle

V.J.T.I.-Rohin Apte
Published 2019-01-09 by SAE International in United States
The Indian government has announced Bharat Stage -6 emission norms to be implemented by 2020 all across Indian cities. The stringent emission norms have resulted in increase of vehicle cost, since they have to be fitted with advanced emission after treatment systems. The emission norms will eventually lead to compromise of power output of vehicles to fit within the norms. With the deteriorating air quality and legalization of stringent emission norms, the trend is towards shifting to use of electric vehicles.The conventional electric vehicles available in current market comprise of lithium-ion battery pack of 11 to 18 kWh energy capacity and giving range of 100 to 150 km. This battery packs have to be charged for 5-6 hours with a dedicated source for complete recharging or for 1 hour fast charging to attain sufficient state of charge to reach the destination. The travel is dependent on charge of battery leading to "range anxiety" among consumers. To deal with it, battery swapping models have been proposed, but implementing such model has not been success till date.…
