Experimental Performance Analysis of Six Cylinder Turbocharged Diesel-Cng Dual Fuel Engine

Dual fuel engine is internal combustion engine which works with two fuels simultaneously. Automobile sector is facing challenge of fossil fuel depletion & reducing harmful emissions to meet stringent environmental norms. Alternate fuels like CNG have capabilities of reducing exhaust emissions from automobiles.CNG has other advantages like lower cost as compared to gasoline & diesel, less noise due to high octane no & clean combustion properties. Diesel-CNG Dual fuel engines offer number of potential advantages like fuel flexibility, lower emissions, higher compression ratio and better efficiency. This paper is based on experimental work done on six cylinder turbocharged engine converted to dual fuel engine by using dual fuel kit from M/s Best Prins, Netherlands. Engine was tested on AVL PUMA engine testing system and emissions were measured on AVL emission measuring equipment. 13 mode ESC test was conducted in diesel mode & dual fuel mode. All points were optimized for engine performance & emissions. Optimized engine parameters & emissions were measured. It was observed that, it was possible to achieve engine performance near toBS III emission norms. Engine testing was carried out at ARAI, pune, India.

Cosmic ray test of INO RPC stack

The India-based Neutrino Observatory (INO) collaboration is planning to build a 50 kt magnetised iron calorimeter (ICAL) detector using glass Resistive Plate Chambers (RPCs) as active detector elements. A stack of 12 such glass RPCs of 1 m ×1 m in area is tracking cosmic ray muons for over three years. In this paper, we will review the constructional aspects of the stack and discuss the performance of the RPCs using this cosmic ray data

Medicinal Plants of India

Crude extracts of fruits, herbs, vegetables, cereals and other plant materials rich in phenolics and antioxidant activity are of prime interest to the food industry because of their ability to retard oxidative degradation of lipids and hence improve the quality and nutritional value of functional food. Concomitantly, the importance of antioxidant constituents of plant materials in the maintenance of health and protection from coronary heart disease and cancer is also raising interest among scientists, food manufacturers and consumers as part of the current trend towards the use of herbal medicine. In addition, the use of complementary alternative medicine (CAM) by patients suffering from chronic disorders, such as cancers, heart, stroke and immune disorders has been well documented. CAMs are either used on their own (alternative treatments) or in addition to conventional medicine (complementary treatments). CAMs can be grouped into herbal medicines derived from medicinal plants, food supplements that include vitamin preparations, trace elements and other substances such as omega-3 fatty acid
