2020-09-25
2020-28-0463
Automakers are being subjected to increasingly strict fuel economy requirements which led OEMs to focus more on Light weighting and Energy efficiency areas. Considering the aforesaid challenges, efforts have been taken in Light weighting of mounting bracket for Engine application. This paper deals with conversion of Engine accessory bracket from Aluminum material to Metal Matrix composite (MMC). In Design phase, existing bracket has been studied for its structural requirements and further Bracket is designed to meet MMC process requirement and CAE carried out for topology optimization and Structural integrity. Finally observations and results were compared for Existing design and Proposed design and further optimization proposed.

In the current landscape of commercial vehicle industry, fuel economy is one of the major parameter for fleet owner’s profitability as well as greenhouse gasses emission. Less fuel efficiency results in more fuel consumption; use of conventional fuel in engines also makes environment polluted. The rapid growth in fuel prices has led to the demand for technologies that can improve the fuel efficiency of the vehicle. Phase change material (PCMs) for Thermal energy storage system (TES) is one of the specific technologies that not only can conserve energy to a large extent but also can reduce emission as well as the dependency on convention fuel. There is a great variety of PCMs that can be used for the extensive range of temperatures, making them attractive in a number of applications in automobiles.

Drink & drive has caused the increased rate of commercial vehicle accidents in the world due to the slow response to judgment and reasoning. According to research study 70% accidents are happened due to drunk & drive, it causes loss of human life and economic damage. Research has proven that drunk drivers exhibit aggressive driving behavior and apply more force during braking. While public health awareness and legal restrictions can assist in educating and discouraging people from drunk & drive, a more fool-proof method is not available in the market for commercial vehicles. Currently, a low cost, fail-safe onboard alcohol detection, and vehicle safety system is the need of the hour. This paper deals with the design & development of a low cost active onboard breath alcohol detection system and it’s on vehicle validation. Further, it explains the type of alcohol detection sensor used, controller design, logic programming and system packaging.

The reduction of tire wear in vehicle is one of the major challenges for engineers. Under-inflated tire can cause reduction in tire life along with decrease in driving stability of vehicle. Efforts have been taken to develop a low-cost auto-tire inflation system integrated in vehicle for reduction in tire wear as well as to avoid periodic checks of tire pressure. This paper deals with the technology and design approach required in the development of auto-tire inflation system for commercial vehicle. This system should have the fundamental role of not only monitoring the tire pressure but also inflating the tire to the recommended level of pressure whenever the pressure is reduced below the recommended level. Different approaches have been worked out for integration of system on vehicle with least modification in existing design.

Downsizing is one of the crucial activities being performed by every automotive engineering organization. The main aim is to reduce - Weight, CO2 emissions and achieve cost benefit. All this is done without any compromise on performance requirement or rather with optimization of system performance. This paper evaluate one such optimization, where-in radiator assembly with two electric fan is targeted for downsizing for small commercial vehicle application. The present two fan radiator is redesigned with thinner core and use of single fan motor assembly. The performance of the heat exchanger is tested for similar conditions back to back on vehicle and optimized to get the balanced benefit in terms of weight, cooling performance and importantly cost. This all is done without any modification in vehicle interface components except electrical connector for fan. The side members and brackets design is also simplified to achieve maximum weight reduction.

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.
