Fuel efficiency

The stock market saw its worst crash since the Great Depression in November 1973. The aviation industry felt the same quake: domestic airline traffic decreased 5% in 1973. The Congressional Hearing on alternative fuels for aviation during the second session of the 98th Congress revealed just how heavy the effect was on airlines. Consuming 6% of the nation’s petroleum product, the civil aviation sector had tripled its energy consumption in the previous decade, thanks…

The authors could have compared time exposed to biomass fuels between men and women, then included interaction terms in their statistical analysis: It appears that exposure duration or fuel composition may act as a modifier of biomass fuel use. The authors state that men are more likely to be exposed due to factors such as tobacco use,1 but that women are more likely to be exposed due to smoke…

that need to be present in order for a wildfire to burn, which firefighters refer to as the fire triangle: fuel, oxygen, and a heat source. Fuel is any flammable material surrounding a fire, including trees, grasses, brush, even homes. The greater an area's fuel load, the more intense the fire. Air supplies the oxygen a fire needs to burn. Heat sources help spark the wildfire and bring fuel to temperatures hot enough to ignite. Lightning, burning campfires or cigarettes, hot winds, and even the…

1 INTRODUCTION While humans have been using fire for many thousands of years, we have only recently in our history recognized the benefit of removing smoke from the home. There is little documentation on the history of chimneys and their function in the home. In western civilization there is record of chimneys being destroyed by an earthquake in 1347 (Butler, n.d.). Most homes had a centrally located hearth that was used for heat and cooking, which had a vent directly above it; While this did…

Slightly crack the acetylene (fuel) cylinder valve until the valve opens. When the valve opens, turn it clockwise another one and one half turn. Adjust the acetylene regulator valve until the gauge reads five psi. You then slightly crack the oxygen cylinder valve. When the valve opens…

the main topic of my project is fire, mainly how it depends on fuel and oxygen to keep going. Fire is important because it is used in a variety of ways all around the world. From heating our meals to burning evidence, fire is a very valuable resource. To keep a fire going, you’ll need three things; fuel, oxygen, and heat. In order to start a fire, a source of heat, like the sun and heaters, will have to concentrate their heat on the fuel( you can concentrate heat in multiple ways like using a…

These tools can be used in the measure of changes. They are Effectiveness and efficiency, Customer satisfaction, Staff satisfaction, Access / environment, Cost and benefit of the change and Waste of resources. Effectiveness and efficiency – organisational and quality assurance, staff appraisals and staff meetings to check and balance any inadequacy cy in the organisation. Customer satisfaction can be monitor…

engine) is an internal combustion engine that uses the compression to initiate ignition and burn the fuel that has been injected into the combustion chamber. This contrasts with spark-ignition engines such as a petrol engine (gasoline engine) or gas engine (using a gaseous fuel as opposed to gasoline), which use a spark plug to ignite an air-fuel mixture. The diesel engines have the highest thermal efficiency in any internal or external combustion engine because of its very high compression…

cost of useful thermal energy of the fossil fuels and that of the substitute biomass fuels. To displace one liter of fuel oil, 3−4kg of biomass fuel will be required or an ETC solar collector area of 0.003 m2 will be required. Reduced cost of fuel: Taking the Kombolcha case as an example, 100% fuel oil replacement would represent 47t of biomass fuel per day. Assuming the average cost of biomass briquettes to be 108US$/t, the total year biomass fuels cost would, therefore, be approximately…
