Abstract

Gasolines sold at our service stations typically have an octane rating between about 87 & 93, & fuels of such octane values are satisfactory for most automotive engines. However for high performance engines in particular, fuels of even higher octane ratings are required. Octane is a measure of a gasoline s antiknock performance its ability to resist knocking, which is a metallic rattling or pinging sound that results from uncontrolled combustion in the engine s cylinders. It may preven ....etc

manually operated paper recycling machine design ppt
Abstract

A manually operated paper-recycling machine was designed and fabricated. This was done to enable waste paper conversion into useful product. The fabricated plant consists of six major component units that include the disc refiner, the hydropulper, the head box, the felt conveyor, the driers and the rollers.

From the results of experimental analysis carried out on the study, it was discovered that for every 0.1kg of used paper fed into the refiner, about 7000ml of water is required ....etc

ABSTRACT
A solar cell is a semiconductor device that converts solar energy into electricity by the photovoltaic effect, representing the fundamental power conversion unit of a photovoltaic system ,works under the principle of a P-N junction that absorbs light , releases electrons and holes , creating a voltage in the cell , which is then applied to load; being environmentally aware, and with the price of living rising at an alarming rate, solar power, generating energy from the natural resources of the sun, has in recent times become quite a ....etc

Abstract

With increasing demand of fuel CO2 emissions are increasing at a large rate, leading to greenhouse effect which has created an alarming condition all over the world, also increased prices, and within some duration fossil fuel will come to end. Today s need is to generate power efficiently and eco-friendly, also think of an alternative fuel source. The paper discusses the same, and gives the best solution for the above. As plants by photosynthesis generate food, the same way we can also generate f ....etc

Abstract:
The oil shocks of 1970s led to spiraling crude oil prices in the world market which prompted planners to view energy security as an issue of national strategic importance. Energy security has an important bearing on achieving national economic development goals and improving the quality of life of the people. World s dependence on crude oil will continue for most part of the 21st century but the continued dependence on crude oil is loaded against it with inherent price volatility linked to finite global r ....etc
