Elimination of Super Chargers in Automobiles by Using Cooling System
Abstract: Nowadays, the fossil fuels are depleting day by day. The efficiency of an automobile has to be increased to overcome the shortage of fossil fuels. If we reduce the consumption of the brake power obtained during combustion for other purposes rather than running the vehicle such as super chargers, cooling systems etc., we can increase the efficiency. We are using almost 35% of the output power of the crankshaft for …

The Effect of Compression on Sound Absorption of Multi-layered Isotropic and Transversely Isotropic Porous Materials at Oblique Incidence
Abstract: Porous materials which are effective in sound absorption in automobile and airplane industry areoften used under compression. This compression is associated with a reduction in thickness and theresulting changes in acoustical properties and non-acoustical parameters of the porous materials.Therefore, these acoustics changes should be taken into account when the behavior of these materialsis studied. So far, the studies on the effect of compression on sound absorption characteristics ofporous materials have …

Emission Analysis Of Butanol and Waste Cooking Oil in VCR Diesel Engine
Abstract: Environmental pollution and depleting energy resources are two major reasons to find a suitable alternative fuel. The experimental study is carried out on a variable compression ratio engine to compare the emissions produced by the engine using the blends of waste cooking oil and that of butanol, separately with the emissions produced by the same engine using neat diesel on the different compression ratio and loads. The blends were prepared …

Performance analysis of Butanol and Waste Cooking Oil bio-diesels in VCR diesel engine
Abstract: Global energy crisis is the key reason for switching to alternate fuels without compromising with environmental standards. This paper focuses on assessing the performance parameters viz. brake thermal efficiency (BTE), brake specific fuel consumption (BSFC), air/fuel ratio and torque against gradually increasing load (0-4 kg) for waste cooking oil (WCO) biodiesel, butanol biodiesel and neat diesel in a variable compression ratio engine. Three different blends of WCO and butanol, separately, …

Assessing the Impact of the Compression Ratio on Emission and Performance Attributes of Jatropha Biodiesel Fuelled VCR Engine.
Abstract: In the view of fast diminishing petroleum reservoirs and polluted environment, it’s the need of time to opt for a viable alternative to diesel fuel. Fuels derived from plant oils or animal fats are better alternatives to diesel fuels. The jatropha derived from the non-edible plant has proven its ability for being an alternative to conventional diesel. The variable compression ratio (VCR) technology is recognised for improving the performance, efficiency, …
