Developing vehicles that achieve optimum fuel economy and acceleration performance is critical to the success of any automotive company, yet many practicing engineers have not received formal training on the broad range of factors which influence vehicle performance. This seminar provides this fundamental understanding through the development of mathematical models that describe the relevant physics and through the hands-on application of automotive test equipment. Attendees will also be introduced to software used to predict vehicle performance.
On-board diagnostics, required by governmental regulations, provide a means for reducing harmful pollutants into the environment. Since being mandated in 1996, the regulations have continued to evolve and require engineers to design systems that meet strict guidelines. This one day seminar is designed to provide an overview of the fundamental design objectives and the features needed to achieve those objectives for generic on-board diagnostics. The basic structure of an on-board diagnostic will be described along with the system definitions needed for successful implementation.
Paper Title - Wiring Harness Optimization towards Wireless vehicle Research and/or Engineering Questions/Objective (maximum 100 words) In current scenario, wiring harness plays a vital role in inter-connecting electrical & electronic components fitted all across the vehicle. As per cable standard, DIN 72551 or ISO 6722, copper conductors being used in stranded wires against cable cross-section & corresponding weight. While going complete wire-less requires each component to have its own battery, ground, transmitter & receiver which indeed is a very costly affair to be employed in vehicle as huge development cost is required. Here I'm suggesting an innovative method to make a vehicle apparently Wire-Less by creating local clusters connected to each other via conventional wiring harness & wire-less module. Such method will apparently give a look of Wire-less vehicle itself & better advantages in terms of installation, service, troubleshooting, uptime & customer delight. Moreover, direct benefits of Cost, Weight, FE will also be achieved.

As Battery cost is expected to see a Downward trend, Electrification of Powertrain in general is expected to pick up and 2wheeler Market is foreseen to be the Flag bearer in this race towards Electrification. In this paper, we would like to emphasize on the Journey of 2wheelers from Conventional Internal combustion Engine to Electrified Powertrains which we foresee in the future. Methodology: EV - Analysis of OEM strategies and upcoming trends in connectivity and electrification. Estimation of current market size of 2Wheeler and segmentation based on different personas. Building survey data based personas around ownership patterns for electric 2Wheelers. Mapping consumer decision process for electric 2Wheelers. Analyse the decision influencers and role of influencers in decision making process. Hybrid - Analysis of different hybrid topologies. Feasibility study via simulation and focus group assessments to evaluate the design. PoC will also be tried to validate the concept.
Internal combustion (IC) engines have been serving as prime source of power in tractors, since late 19th Century. Over this period, there have been significant improvements in IC engine technology leading to increased power density, reduction in tailpipe emissions and refinement in powertrain noise of tractors. As the regulations governing tailpipe emissions continue to be more stringent, original equipment manufacturers also have initiated work on innovative approaches such as diesel-electric hybrid powertrains to ensure compliance with new norms. However, introduction of such technologies may impact customer’s auditory, vibratory and drivability perceptions. Absence of conventional IC engine noise, association of electric whistle and whine, torque changes with activation/de-activation of motors and transmission behavior under transient conditions may result in new NVH issues in hybrid electric vehicles.
Hybridization continues to be growing trend in vehicular applications. Current study shows a holistic system approach for the design & integration of the powertrain in Off-Highway tractor applications. It includes study & benchmarking of system architecture of an all-electric and diesel-electric drive systems as per application requirement. Further comprehensive study was done on functional components for an electric powertrain, which includes electric drives, batteries & controllers. Selection & design of these components was studied & component selection approach was developed for typical Off-Highway tractor application. Current study was divided into three parts. 1.Study of different Off-Highway tractor applications & selection of all-electric, series & parallel hybrid architectures as per application requirement.
"According to Data on Road accidents in India by Transport Research Wing of Ministry of Road Transport & Highways, more than 4 Lakhs road accidents happened every year from year 2003 to 2017. Poor road conditions and badly designed roads are the common cause of road accidents besides the driver's negligence. Poor roads and badly designed speed breakers are common in developing countries. Apart from accidents, poor road conditions can cause excessive fuel consumption & damage to vehicles. Road condition monitoring solutions aim to warn the drivers of upcoming bad patch on the road and optionally report road conditions to authorities. There are multiple existing solutions that use motion sensors and GPS to detect a bad patch on the road. The presented solution builds over capability of existing solutions by adding useful features making it more practical and useful.
Since the 20th century increase in the number of cars in the major cities is been a point of concern because of the toxic gasses being emitted from the engine of an automobile. These gasses are polluting the atmosphere and degrading the air to breathe. The main gasses responsible for the degradation of air quality are carbon monoxide, hydrocarbon and oxides of nitrogen. There is a necessity to find ways to reduce the pollution emitted into the atmosphere from the automobile. The source of emission is either evaporation from fuel tank or carburetor which is easy to be dealt with or harmful gasses due to improper combustion which is a concern for the environment. The two ways to reduce these emissions are, modification in the engine to minimize the production of harmful gases and to treat the harmful gasses emitted from the engine before blowing it into the atmosphere from the exhaust. Catalysts help to break harmful gasses into smaller compounds that are environment-friendly.
Biodiesel can supplement petroleum product as a "perfect vitality source". It can ensure nature by diminishing CO2, SO2, CO, HC emission to an extent. The carbon cycle of Biodiesel is dynamic through the photosynthesis procedure .Plants ingest CO2, or, in other words those released by the biodiesel ignition process. Utilizing biodiesel can all the more adequately lessen the outflow of CO2, secure the indigenous habitat and keep up the environmental equalization, contrasted with the utilization of petroleum product. This paper considers the issues and gives understanding on the utilization of bio diesel in existing passenger vehicles which runs on diesel as a fuel. Because of increment in use of non-renewable energy sources viz., petroleum products are on an exponential decline. Today we have an option of electric vehicle or fuel cell based vehicles but what about the existing infrastructures of Billions of vehicles plying on Indian road. Bio diesel as a fuel solves this issue.
Energy policy reviews state that automobiles contribute 25% of the total Carbon-di-oxide (CO2) emission. The current trend in emission control techniques of automobile exhaust is to reduce CO2 emission. We know that CO2 is a greenhouse gas and it leads to global warming. Conversion of CO2 into carbon and oxygen is a difficult and energy consuming process when compared to the catalytic action of catalytic converters on CO, HC and NOX. The best way to reduce it is to capture it from the source, store it and use it for industry applications. To physically capture the CO2 from the engine exhaust, adsorbents like molecular sieves are utilized. When compared to other methods of CO2 separation, adsorption technique consumes less energy and the sieves can be regenerated, reused and recycled once it is completely saturated. In this research work, zeolite X13 was chosen as a molecular sieve to adsorb CO2 from the exhaust.
