In the modern automobile scenario in developing countries, the customers are getting more meticulous and the market more competitive. Now even the budget vehicle customer expects desirable vehicle performance in specific use cases of the vehicle that were previously not focused by designers. Hence, the focus on perceived quality challenges automobile engineers to go the extra mile when it comes to the cost-effective design of parts that are tangible to the customer. A vehicle's cowl cover is one such exterior component. The primary functions of this part are to provide air intake opening for the HVAC system and cover the components like wiper motor. The aesthetic function is to cover the gaps between windshield, hood, and fender as seamlessly as possible. A specific role of cowl cover, which calls for a designer's attention, is its load-bearing capability. This component has to be stiff enough to bear external loads like snow accumulation or application of hand on the part by customer or service personnel. Simultaneously, it plays a significant role in absorbing the energy of a…

To reduce global warming, Honda has been worked on emission reduction and fuel efficiency enhancement by applying fuel injection systems. The productivity enhancement and cost reduction are strongly demanded in developing countries as the market is expanding. To enhance productivity and reduce cost of ECU, application of the semiconductor production method has been started for printed circuits with edge connectors. However, products that fully meet the requirements of us have not been realized so far. The ECU developed this time has a structure shielding the whole PCB package except the edge connector terminals. Thus, the waterproofness required for an ECU has realized, as a standalone component, as the first in the world (by Honda survey). To achieve that, we developed transfer molding dies equipped with a unique mechanism never been applied. Moreover, we developed an epoxy resin that eliminates the after cure process. Thus, productivity of 5 times over conventional was realized with a multi-cavity molding capable of moldings more than 10 pieces at a time. Furthermore, a new waterproof card-edge connector was developed, in…

Process Turns Sand and Plant Materials into a Water Filtration Tool

  • Magazine Article
  • TBMG-35819
Published 2020-01-01 by Tech Briefs Media Group in United States

According to the United Nations, 2.1 billion people lack access to safely managed drinking water services and the majority live in developing nations. A process was developed that uses sand and plant materials readily available in many developing nations to create a cheap and effective water filtration medium called “f-sand.” F-sand uses proteins from the Moringa oleifera plant, a tree native to India that grows well in tropical and subtropical climates. The tree is cultivated for food and natural oils, and the seeds are already used for a type of rudimentary water purification; however, this traditional means of purification leaves behind high amounts of dissolved organic carbon (DOC) from the seeds, allowing bacteria to regrow after just 24 hours. This leaves only a short window in which the water is drinkable.

Vehicular accidents are life-threatening and result in fatal casualties in developing country such as India. According to estimates, traffic accidents kill more people in India than diseases like Cancer and AIDS. More than 150,000 people are killed every year in traffic accidents in India, which works out to 400 fatalities a day, far higher than developed auto markets like the U.S., which had logged about 40,000 deaths in 2016. The World Health Organization estimates road accidents cost most countries about 3 per cent of their gross domestic product.India being the fastest growing economy will be the world’s third-largest car market after China and the U.S. by 2020, according to automobile researchers.According to research study most of death cause due to not getting help on time to the injured person. Research has proven that if injured person is not found any option of help then they also lose the power to fight such critical situation due to psychological effect. When vehicle met accident, people are not getting on time support, this delay is the major cause…

Selection of Reference Flux Linkage for Direct Torque Control Based Induction Motor Drive in Electric Vehicle Applications

SAE International Journal of Alternative Powertrains

Indian Institute of Technology Guwahati, India-Amit Kumar Singh, Upendra Reddy, Kashyap Kumar Prabhakar, Praveen Kumar
  • Journal Article

Published 2019-04-08 by SAE International in United States
The surge in economic activities, in the developing nations, has resulted in rapid expansion of urban centres. This expansion of cities has caused a rapid increase in vehicular traffic, which in turn has caused deterioration of air quality. To overcome the problem of unprecedented air pollution, the governments worldwide have framed policies for faster adoption of electric vehicles. One of the major challenges faced is the development of low- cost drive for these vehicles and keeping the imports to a minimum. As a result of this, the trend is to move away from the permanent magnet-based motor technology and to use induction motor-based drivetrain. For the induction motors to be successful in electric vehicle drivetrain application, it is important to have a robust speed control algorithm. This work aims at adapting a direct torque control technique for induction motor’s speed control. The work addresses the impact of reference flux linkage on the operation of an induction motor for direct torque control over a wide range of operation. A Finite Element Analysis based induction motor model…

Determination of Climatic Boundary Conditions for Vehicular Real Driving Emission Tests

Ashok Leyland Ltd.-Yoganandam Sriramulu, Senthil Kanagaraj, Manikandan R, Karthikeyan KJ
Published 2019-04-02 by SAE International in United States
Vehicular Emission testing is gaining importance over the past years in the wake of requirements for real driving emissions with implementation of RDE packages across Europe / USA and various developing countries.Extending the same concept for other countries poses slight challenges in terms of geographical and climatic conditions prevailing in the country, where the climatic conditions are differing from Europe / USA. It is a challenge to accept the same boundary conditions as in Europe, at the same time the challenge is to find a threshold number in a more scientific manner.This study concentrates on determination and recommendation of thresholds for ambient temperature and altitude. The basis for temperature threshold would be to determine the percentage of time the temperature exceeded beyond the threshold over year in the country. The basis for Altitude is considered based on the percentage of total length of roads beyond the threshold altitude limit. For both threshold limits, the base data are obtained from open source publicly available and the processing of the data to suit our requirements is the…

Comfort Improvement in Air Conditioned Buses through the Homogenous Air Flow along the Hatrack by Using Different Types of Baffle Plates

VE Commercial Vehicles Ltd-Saurabh Sharma, Akarsh Sathish, Jitendra Thakur, Sushil Shende
Published 2019-01-09 by SAE International in United States
India being a developing nation, there is significant improvement of road infrastructure across the country as well as the spending power and earnings of the common man. This leads to the new trend of customers willing to pay for a more comfortable travel through AC buses. To satisfy these demands, OEM’s are forced develop and manufacture huge numbers of AC buses. Although the OEM’s are meeting this demand of quantity, the quality aspect of the buses, i.e., climate comfort, is still subpar. One of the main reasons for this sub-quality comfort is the non homogenous distribution of air flow along the bus. This non homogeneity leads to the centre of the bus having very high air flow and thus overcooling conditions, while the front and rear of the bus receive very little air flow and thus receive under-cooling conditions.To solve this concern of non homogeneity, we incorporated a new design in the hatrack, through the implementation of baffles and deflector in the hatrack. With this new design, air flow distribution was analyzed through CFD and…

Development of an Innovative Transmission System for Two-Wheelers Using TRIZ Methodology

The Automotive Research Association of India-Enanko Moulick, Kiran Wani
Published 2019-01-09 by SAE International in United States
In a developing country like India, Two-wheelers dominate the automotive market with around 80% market shares. In Indian city traffic conditions, driving a two wheeler is a tiresome job. Manual transmission makes this task even further uncomfortable. So an automatic transmission is a better solution. A new automatic transmission system is developed which can reduce fatigue of drivers. Steps of ARIZ (Algorithm for Inventive Problem Solving) were followed. Ideas or concepts for the design were proposed from various fields and were compared for various parameters like size, weight, complexity, manufacturability, feasibility, efficiency and cost. They were also compared with the existing transmission systems. Based upon the results of the comparison, 5 designs were selected and they were analyzed thoroughly. Finally one design was selected. It was further studied in detailed and its improving and worsening features are noted and with the help of contradiction matrix and 40 principles contradictions were removed. S-Curve for the new system is predicted and the effects of the new design on super system are shown with the help of system…
