The increasing vehicular population causing consumption of petroleum fuels at a faster rate and causes increase in the danger of petroleum fuels depletion and the remarkable increase in high crude oil prices. The increasing consumption of petroleum products has been a matter of great concern for the country for the financial growth as well as environmental pollution abatement. The situation off...

Existing diesel engines are under stringent emission regulation particularly of smoke and particulate matter in their exhaust. Compressed Natural Gas and Diesel dual fuel operation is regarded as one of the best ways to control emissions from diesel engines and simultaneously saving petroleum based diesel fuel. Dual fuel engine is a conventional diesel engine which burn either gaseous fuel or d...

In order to understand how to bring out the most power from a car’s engine, we needed to learn how an engine works. The main focus of this research was to tune the engine and create a fuel map that would allow it to run at its optimum level. We used the Win Tec-GT computer software to test the performance of a 2002 Yamaha YZFR6 engine that the Rutgers 2008 Racing Team uses in their car. To easi...

This study investigated the emission characteristics of ultrafine particles based on test bench and on-board measurements. The bench test results showed the ultrafine particle number concentration of the diesel engine to be in the range of (0.56-8.35) x 10(8) cm(-3). The on-board measurement results illustrated that the ultrafine particles were strongly correlated with changes in real-world dri...

one of the methods to reduce the emissions in a diesel engine is by oxygen introduction into the combustion chamber which can be done by supplying the oxygen into the inlet manifold during suction stroke. oxygen affects different parameters such as brake thermal efficiency, fuel consumption, nox and smoke at different load conditions. load test was conducted for various concentrations of oxygen...

Use of liquefied petroleum gas (LPG) in compression-ignition (C-I) engines has always been considered important in the diesel engineering field. This is due to its easy accessibility and good combustion characteristics. In this paper the application of LPG fuel along with diesel oil in a direct- injection automotive diesel engine is experimentally investigated. In order to convert the pure dies...

Increasingly restrictive emission regulations and renewed focus on energy efficiency drive the current researches to find alternative fuels and their related better combustion strategies. In this regard, dual fuel engines, in which natural gas fuel is used as a main fuel and diesel fuel is employed as a pilot fuel, have received considerable attention. However, poor fuel utilization efficiencie...

As the size of the web continues to grow, searching it for useful information has become increasingly difficult. Also study reports that sufficient of current internet traffic and bandwidth consumption are due to the web crawlers that retrieve pages for indexing by the different search engines. Moreover, due to the dynamic nature of the web, it becomes very difficult for a search engine to prov...
