Fuel efficiency

Today, many rely on fossil fuels to help with daily necessities such as delivering electricity, powering vehicles, and heating their homes. Fossil fuels have been widely used since the Industrial Revolution. Since then, the use of fossil fuels has greatly grown. Fossil fuels are any naturally occurring carbon-containing material that, when burned with air to produce heat or energy that can be converted into liquid fuels and other hydrocarbon (carbon bonded to hydrogen) products (Speight, James).…

Summary of each fuel – and their strength and weakness Natural Gas Fuel (- NONRENEWABLE) 1. Propane – Uses LPG 2. CNG – Burns methane Propane engines last twice as long as conventional engines – lower maintenance. Range is 25% less than gasoline cars because of the lower energy content of fuel Performance is similar to a gasoline-powered car Natural gas fuels emit 1/3rd fewer reactive organic gases. HYDROGEN FUEL Hydrogen internal combustion engine (HFCE) produces nitrous oxides.…

Rudolf Diesel, a German engineer in 1892. Unlike a Sparked Ignition (SI) engine, Diesel designed the engine to run on vegetable oil, more specifically peanut oil. 2. CI vs SI, the difference As its name suggests, the CI engine’s ignition of the air-fuel mixture is caused by the mechanism compression rather than a spark from a spark plug of SI engine. This difference of operation gives very different characteristics to these engines and thus allows the CI run more efficiently by having a higher…

quantities. On the other hand, the advantages for non-renewable energy are ease of accessibility, cost efficiency, and the ability to produce a large amount of energy. While the disadvantages comprise of: environmental impact, limited supply, and dangerous work environments. In the current age, we need energy that can be produced in great quantity, as cheap as we can. This is exactly what we find in fossil fuels. Due to the large amount of resources such as coal and petroleum, dispersed…

this project. Following on, the aims and objectives, overview, project scope and structure of this thesis are outlined. 1.1 Motivations The most important aspects of an aircraft, in today’s aerospace industry are environmental friendliness and fuel efficiency.…

coming out each day. Awareness has been generated, environmental laws have been passed and punishments have been given out, all in the hope of reducing energy consumption and wastage. Motorsport is an extensive user of resources, especially fossil fuels for propulsion and with increasing awareness of environmental issues; it stands to lose the following of its fans if they realize the weight that motorsport transfers to the Earth’s load. Sustainability as a concept encompasses a wide range of…

innovative ways to obtain energy as affluence may be related closely to more efficient use of a wider variety of energy sources as it is to total energy consumption now. Our country South Africa, like all other countries is more reliant on fossil fuels (coal, oil and gas). Approximately 89% of South African energy supply is from fossil…

parts of the world, electricity can be found almost anywhere. Electric cars require electricity to operate but has a big cost advantage over vehicles powered by gasoline engines. Seeing the obvious efficiency that electric vehicles have over internal combustion models, the cost per mile of electricity to fuel is approximately one to three. And because electric vehicles do not have exhaust systems and don’t need oil changes, maintenance costs are lower (Berman, 2016). The impact that electric…

import of fossil fuel from other countries and stimulate the development of new and most efficient technologies; however, there is some disadvantages in unlimited sources. The installation and maintenance prices are higher than non-renewable. Eolic energy demand a large space, and make too much noise; hydroelectric usually demands a deforestation, and biomass produces greenhouse gases (Shah, 2011). There are many advantages of using non-renewable energy. This kind has a high efficiency, is easy…

variations, either locally, regionally or across the globe” (Union of Concerned Scientists 2011, p185). Why Toronto is still cold and negative degree end of April?. Burning fossil fuel, deforestation and waste of energy are the major contributions to climate change. To reduce the climate change, people need to reduce fossil fuels, protect forests and save energy. Before starting to examine the problem of climate change, it is necessary that differentiate…
