Fuels are the most important energy source in world today. Fuels is very useful to people. We can use fuel by transportation, heat, electricity and science which means fuels is related with our lifestyle.
Diesel is common fuels in our world. Many people have chosen diesel fuel to lower running cost reason. Diesel is composed of about 75% saturated hydro carbons and 25% aromatic hydro carbons. .
Diesel is created from 4 steps by induction, compression, and ignition and exhaust 4 steps processed. As First step induction, the air is drawn into the opened valve when the piston starts moving down the bore. As second step compression, the inlet valve closes at the bottom of the stroke. Thus the piston is able to rise s compress air. As third step ignition, it ignites and force the piston down after fuel is squirted in at the top of the stroke. As Final step exhaust, on the piston’s upward level, the exhaust valve open and exhaust gas is expelled.
LPG is called propane. LPG burns slower than petrol so the ignition timing is slightly retarded. In a properly converted engine the camshaft is also changed to extend the intake valve timing and retard it slightly as well.
The major difference is that a petrol engine uses a carburettor and an LPG one uses a mixer. A carburettor takes liquid fuel, atomizes it and mixes it with air. A mixer takes LPG vapor and mixes it with air.
A petrol engine is more forgiving of running lean. It will run a bit hot. If an LPG engine is allowed to run lean it will burn out the exhaust valves very quickly.
Biofuels are short for biological fuels. A fuel is a substance that stores a form of energy. Usually this energy is stored in chemical bonds. It is created from grass, house wastage and others. The...

... gas is often rich in carbon dioxide and hydrogen sulphide. It is used mainly for heating though it is also used for electricity production mostly at peak times and as a backup for wind power.
There are bit advantages of natural gas.
Natural gas is created from the trash. Thus it has very low emission, it is easy to move around somewhere and most advantages is very cheaper than other fuel. As well as natural gas is able to provide electricity 24 hours, a week.
Despite the many advantage of natural gas, there are also many disadvantages too.
Natural gas is not renewable source energy which means natural gas is going to deplete eventually like oil, natural gas is very highly combustible and it is able to explosions easily. Thus it is very dangerous and natural gas cause pollution of earth. Especially natural gas cause toxicity to water thus it cause water pollution.

- Electricity plays a main role in our world. It's important to know how electricity works and how electricity is created. Electricity could either be made by renewable and non-renewable source. Renewable can be created by itself and non-renewable can't recreate by itself. A non-renewable source requires fossil fuels while renewable does not. My renewable source is solar power and for non-renewable fossil fuel is coal. Solar power is a renewable alternative energy. The sun helps the solar power to produce energy and converted to electricity.... [tags: source, electricity, energy, solar]

- Search for an Alternative Fuel Source for Automobiles Since it’s invention and birth in 1886 automobiles have influenced the world in a huge way. It saved people a lot of energy, time and money. Motorized wagons replaced horse carriages and within a few decades Ford started making affordable models of cars with higher efficiency, which revolutionized the concept of transportation. The first ever car that was built was powered by steam. But with development in science and technology other efficient fuel sources were invented.... [tags: electricity, solar power, hybrids]

- “Almost every way we make electricity today, except for the emerging renewables and nuclear, puts out CO2. And so, what we're going to have to do at a global scale, is create a new system. And so, we need energy miracles.” Bill Gates means that nuclear energy will be the future of the world. And also the whole world uses about 44,000,000 kWh of electricity every day (Greenbang). For such enormous amount of electricity, we need to use nuclear energy. According to multiple studies, using nuclear energy can produce an enormous amount of electricity, require a lot of money to use it, provide a good environment to for earth, and be really safe....

- Fuel Cells as an Attempt of a Capitalist Technological Fix One of the main variables used when measuring the ecological impact of a given society, populous, or nation is the variable of technology. Currently, in a world rightfully beseeched with an uncomfortable mix caution and fear of potential future ecological catastrophe, alternative energy sources are being discussed, researched and developed in many advanced industrialized nations as potential ways to technologically postpone or perhaps even fix a major impending crisis of global Capitalism....

- It’s a common problem everybody has at least a teeny bit of care for: “Fossil Fuel Usage Destroying Earth’s Environment!” Thus, scientists have proposed many alternative fuels useable in place of fossil fuels. However, it seems none of these alternative fuels come without a drawback of some kind. Which, if any, alternative fuel is truly practical and an effective substitute, yet safe for the environment. During the 1960’s and 1970’s, people began to fear for what would happen should the world’s supply of fossil fuels run dry (Sustainable).... [tags: Sensible Fuels,Natural Resources, Earth]
