Amidst ever decreasing fuel resources and constantly increasing air pollution, the fundamental sustainability of present energy system has been put into question. The present reserve of Petroleum products is slowly dying out, widening the gap between global energy supply and energy consumption. As per 2008, energy used on a global scale is about 142.3 Terawatt-Hour, which is about 39% higher than that of 1990.I am attempting to develop a tri fuel system without additives in conventional C.I. engine to increasing the performance and to reduce emission of pollutants. Finally I have decided to use following fuel as a tri-fuel in engine to increase the performance and reducing the emission of an engine1) DIESEL 2) JATROPHA 3) LPG
Keywords : Compression-Ignition (Diesel) Engine, C.I. engine
In some vehicles there are problem of cold starting and overheating. For the experiment we have selected Scooty pep+. In Scooty pep+ it have 88-CC single cylinder air cooled petrol engine. The major problem in this model is, 1. Cold Starting 2. Transmission system produce heat. Due to these problems a good Scooty pep+ cannot exist in market. In the winter season the vehicle can’t start easily. Due to cold starting problem, the vehicle emits more NOx, hydrocarbon (HC) and carbon monoxides (CO). Which can reduce the efficiency and life of vehicle. In this project we will solve the problem of cold starting in vehicle by modification of engine. For the problem of the overheat produce, we will do the material coating on the piston by the material which have less thermal co-efficient so that heat cannot easily dissipate to the transmission. To increase the combustion characteristics we will use different spark plug with different spark intensity.

GPS navigators has widely adopt by drivers. However, due to this sensibility of GPS signals to terrains, vehicles cannot to get their locations, when they are anyone inside a tunnel or a road it’s surrounded by high rises, where satellite signal is ended. This mainly used for safety and convenience problems. But the VANETS advance into their critical areas and to become more dependent on these localization systems. GPS is starting to locate some uncertain problems, such not always being the available or not being robust enough for this some different applications. For the reason, a number of other localizations techniques such as Cellular Localization, Dead Reckoning, and Image Video Localization have been used in VANETs to overcome the GPS limitation. To address this issues, to proposes a novel Grid based On road localization system (GOT), where these vehicles with and without accurate of GPS signals self organizes into a Vehicular Ad Hoc Network (VANET), exchange the locations and distance information and helps to each other’s to calculate an accurate position for all these vehicles inside the network. The location information’s can be exchanged among vehicles one or multiple hops away in this paper.

This paper presents a Reducing Human Effort: Web Data Mining, Learning a New Characteristics from Big data, reducing human effort in extracting precise information from undetected Web sites. Our approach aims at automatically adapting the information extraction knowledge previously learned from a source Web site to a new undetected site, at the same time, discovering previously undetected attributes. There is a two kinds of text related evidences from the source Web site are considered. The first kind of evidences is obtained from the extraction pattern contained in the previously learned wrapper. The second kind of evidences is derived from the previously extracted or collected items. A generative model for the generation of the web site independent content information and the site dependent layout format of the text fragments related to attribute values contained in a Web page is designed to connect the insecurity involved. We have conducted extensive experiments from more than 50 real world Web sites in more than five different domains to demonstrate the effectiveness of our context.

In today’s scenario objective of manufacturing industries to produce product of low cost, high quality in short time. Which give more quality product in less time and help in increase in industry’s profit this is done by selection of correct machine tool lets us focus on lathe, as we all know lathe machine is basic (generic) machine in manufacturing industry and maximum work is taken from it. Lathe machine works on three cutting parameter. That’s why the selection of correct cutting parameter is important. In lathe machine cutting parameters are depth of cut, feed rate and spindle speed (cutting speed). But as we know the spindle speed is limited and every material has their own optimum cutting speed. So that we focused on spindle speed generally power is transmit by gearbox and stepped cone pulley so that the output spindle speed is limited generally in kirloskar harihar D-1 lathe machine uses cone stepped pulley and number of output spindle speed is eight that is from four direct speeds and four from back gear.

Now a day’s energy crises and pollution are major problems. The present investigation is to enhance performance and lower emission characteristics of a single cylinder spark ignition engine operating with hydrogen blends. The hydrogen is blended in different percentage of 5%, 10% & 15% of petrol in a four stroke single cylinder. The load is varied from no load to full load in step by step. The engine in which the experiment to be conducted is a variable speed engine. To change the speed an accelerator is connected with carburetor. The performance and emissions parameter of engine are. 1) Brake Thermal Efficiency, 2) Brake Specific Energy Consumption, 3) Volumetric Efficiency, 4) Emission (CO HC NOx). These all parameter are to be determined and compared with base line readings of petrol.

This manuscript investigates research done in the field of harmonic drives. A brief synopsis of papers dealing with material analysis, optimized design parameters for harmonic drive are presented. Another research work investigating the use of harmonic drives for space applications is discussed at length. Lastly, a work discussing optimized flex spline design, interference study and micro harmonic drive design is also put forward in this manuscript.
