Cost and limited reserves of conventional fossil fuels have intensified the search for alternative fuels for use in internal combustion engines. A possible alternative engine fuel is vegetable oil because it is a clean burning, renewable, non-toxic, biodegradable and environmentally friendly transportation fuel. It can be used in a neat form without any modification of the engine. Vegetable oil...

Two cottonseed oil biodiesel samples (cottonseed oil methyl esters, COME) produced in Clemson lab, together with other two commercial cottonseed oil biodiesels were evaluated on their engine performance with the No. 2 diesel fuel as a reference. The results revealed that emission of CO, CO2 and NOx from cottonseed oil biodiesels was lower than that of the No. 2 diesel fuel. CO decreased by 13.8...

The effect of variation in thermal conductivity of light water reactor fuel elements on core response during loss-of-coolant accident scenarios is examined. Initially, a simplified numerical analysis is utilized to determine the time scales associated with dissipation of stored energy from the fuel into the coolant once the fission reaction is stopped. The analysis is then followed by full reac...

it seems we might be allowed to trace a serious rivalry between two great oil companies of great britain, i.e. anglo-iranian oil company and royal dutch shell- at the eve of 20th century. this presumed rivalry itself seemed to be a result of two important developments in british industry: conversion of the fuel consumption of british navy from coal to petrol; a development which raised the comp...

the catalytic cracking of a fuel oil over fluid catalytic cracking (fcc) catalyst has been investigated applying different additives. catalyst mixtures consisting of a equilibrium fcc catalyst (e-cat) blended with zsm-5, mcm-41 and mordenite additives were examined at the additive levels of 25 wt.%. the catalytic performance of the matrix was studied in a fixed bed micro-activity test unit (mat...

Biodiesel are becoming popular as alternative eco-friendly fuel now days. The petroleum product requirement is going on increasing day by day in India with limited resources in the oil pool. Crisis of petroleum fuel and import of fossil fuel is giving a high impact on the economy and development. Besides the economy and development, fossil fuel also leads to a major problem like global warming ...

Several strategies are currently being investigated for conversion of incident sunlight into renewable sources of energy, and photocatalytic or photoelectrochemical production of solar fuels can provide an important alternative. Titanium dioxide (TiO2) has been heavily investigated as a material of choice due to its excellent optoelectronic properties and stability, and anion-doping proposed as...

Using low price heavy fuel oil (HFO) in high-speed diesel engines is a practical way to reduce running costs. However, most high-speed diesel engines’ fuel systems and combustion systems cannot adapt to HFO. This causes the problem of deterioration of combustion performance. In order to solve this problem, the authors have modified the fuel injection system and combustion system of a high-speed...

This report addresses problems associated with U.S. fuel cell vehicle production and a limited platinum supply. Polymer Electrolyte Membrane (PEM) fuel cells, which use a platinum catalyst, could place strain on the platinum market if fuel cell vehicles are widely produced. We developed a dynamic hypothesis, identified causal relationships, and created a system dynamics model in iThink. Based o...

This research work depends on enhancing the execution of the diesel engine when they utilized bio diesel oil as an optional fuel without real alteration of engine design. It is also required to grow non edible feed stocks in the waste or marginal land of Gujarat. Work goal is to recognize best suitable Bio-Diesel mix by keeping numerous parameters on it. Bio-Diesel mixes will be given credit sc...
