Fuel Cells for Transportation

2022-09-01
This is a three-day course which provides a comprehensive and up to date introduction to fuel cells for use in automotive engineering applications. It is intended for engineers and particularly engineering managers who want to jump‐start their understanding of this emerging technology and to enable them to engage in its development. Following a brief description of fuel cells and how they work, how they integrate and add value, and how hydrogen is produced, stored and distributed, the course will provide the status of the technology from fundamentals through to practical implementation.

High Voltage Vehicle Safety Systems and PPE

2021-10-18
High voltage vehicle safety is a primary concern for every technician or engineer involved in developing, diagnosing or repairing hybrid or electric vehicles. Engineers/technicians working in this field should complete safety training before they interface with hybrid, plug-in or electric vehicles.

Fundamentals of High Voltage xEV, Safety, and PPE

2021-10-15
Do you know what personal protective equipment (PPE), tools, and instruments are needed to keep you safe around high voltage (HV) vehicles? Are you aware of how to protect yourself or your employees when working around high voltage systems and platforms? Safety is paramount when working around any type of high voltage. As electric vehicles (EV) and EV fleets become more prevalent, the critical need for OEMs, suppliers, companies, and organizations to provide comprehensive safety training for teams working with or around xEV systems and platforms increases.

Inspired from innovative global products, the domestic market is striving to develop novel technologies like the proposed On-Board weighing system, to enhance road safety and meet the upcoming challenging standards. Indigenous & economical payload sensing mechanism is essential to follow the stringent norms proposed to overlook the current scenario/issue of overloading in commercial vehicles. Over-loading results in tire damage with non-uniform tire degradation. The fuel economy is also severely affected due to excessive payload transportation. Proposed technology aims to provide effective payload data of vehicle, for very less investment and effort. Such a requirement calls for innovative designs and approaches to integrate them into commercial vehicles. The existing systems of this nature are not only expensive but also bulky, and often out of reach of the regular customer.

INVESTIGATION OF SQUEAK AND RATTLE PROBLEMS IN VEHICLE COMPONENTS BY USING SIMULATION & DOE TECHNIQUES

Over the past several decades, the automotive industry is more focused on reducing engine, wind, and road noise to improve comfort. However, as background noise levels continue to decrease, the squeaks and rattles created by the many components inside and outside the vehicle become gradually noticeable, and annoying. In electric vehicles the squeaks and rattles noise becomes more dominant than other type of noise as a result of absence of dominant noise source of engine from conventional petrol/diesel vehicle. In this paper, we are proposing a simulation methodology to develop a systematic approach to identify and solve squeak and rattle problems in vehicle components/sub-assemblies at primary stage of product development. This work will present a unique approach in understanding varied methods and Design of Experiments (DOE) techniques used to identify root-cause of squeak and rattle problems and to find a solution by using numerical methods.

In order to meet the challenges of future CAFE regulations & pollutant emission, vehicle fuel efficiency must be improved upon without compromising vehicle performance. Optimization of engine breathing & its impact on vehicle level fuel economy, performance needs balance between conflicting requirements of vehicle Fuel Economy, performance & drivability. In this study a Port Fuel Injection, naturally aspirated small passenger car gasoline engine was selected which was being used in a typical small passenger car. Simulation approach was used to investigate vehicle fuel economy and performance, where-in 1D CFD Engine model was used to investigate and optimize Valve train events (Intake and exhaust valve open and close timings) for best fuel economy. Engine Simulation software is physics based and uses a phenomenological approach 0-D turbulent combustion model to calculate engine performance parameters. Engine simulation model was calibrated within 95% accuracy of test data.

From April 2020 BS 6 phase 1 legislation has come into place in India. Further in the coming years from 2022 CAFÉ norms will be implemented targeting 122 g/km CO2 fleet emissions. Also from year 2023 onwards BS 6 phase 2 emission legislation with RDE cycle will be in place. With the expensive exhaust after-treatment system needed for meeting BS 6 norms, the Diesel powertrain based vehicles cost has increased further creating even further price difference to it's Gasoline fuel variants. Additionally the price difference between Diesel and Gasoline fuel is always reducing. These reasons have changed the buying pattern of passenger cars in India, with vehicle powered by engine<1.5 L displacements have gradually shifted predominantly to Gasoline powertrain. The impact of this will further stress the fleet CO2 emissions for manufacturers.
