Diesel vs Gas
Gasoline vs. Diesel
You’re in the market for a new truck; you have an idea about what you want but not quite sure if you want a gasoline or a diesel engine. Well, gas and diesel engines are very similar yet different in quite a few ways.
At first glance, someone who doesn’t know much about either of the two engines might ask, “What’s the difference?” To the untrained eye they might look exactly alike, but don’t judge the engine by its exterior look.
Gas engines are mainly used by the individual in personal vehicles whereas diesels are very popular in the commercial and industrial fields. Diesel engines are used by the navy in their ships and by the army in their tanks and big trucks. Some of the main reasons for choosing this engine are that diesels are more reliable and durable than gas engines. Diesels are built to last and built to work. Also the power output is greater in a diesel, thus more economical.
From an environmental point of view a diesel doesn't burn as clean as gasoline. Apart from particulate matter (which modern diesel filters can minimize), burning a gallon of diesel will generate more C02 than burning a gallon of premium gasoline. You'd need a fuel savings of around more than 15% percent to compensate for the increase in C02 output compared to the same car powered with an equally powerful gasoline engine.
The way the gas and diesel engines start are a major difference in the two. Gas engines use spark plugs to ignite the fuel. Diesels do not have spark plugs, they use compression. A gasoline engine intakes a mixture of gas and air, compresses it and ignites the mixture with a spark from the spark plug. A diesel engine takes in just air, compresses it, and then injects fuel into the compressed air. The heat of the compressed air lights the fuel. Both modern engines use Electronic Fuel Injection to inject fuel into the cylinders.
Both the gas and diesels are internal combustion engines. Inside an internal combustion engine explosions of fuel

    Biodiesel refers to a vegetable oil- or animal fat-based diesel fuel. Biodiesel is meant to be used in standard diesel engines and is thus distinct from the vegetable and waste oils used to fuel converted diesel engines. Biodiesel can be used alone, or blended with petro diesel. Biodiesel has better lubricating properties and much higher octane ratings than today's lower sulfur diesel fuels. Biodiesel addition reduces fuel system wear, and in low levels in high pressure systems increases the life of the fuel injection equipment that relies on the fuel for its lubrication. Depending on the engine, this might include high pressure injection pumps, pump injectors and fuel injectors. Biodiesel has been known to break down deposits of residue in the fuel lines where petro diesel has been used. As a result, fuel filters may become clogged with particulates if a quick transition to pure biodiesel is made. Therefore, it is recommended to change the fuel filters on engines and heaters shortly after first switching to a biodiesel blend. In 2007, in the United States, average retail prices, including federal and state fuel taxes, of B2 and B5 were lower than petroleum diesel by about 12 cents, and B20 blends were the same as petro diesel. However, as part as a dramatic shift in diesel pricing, by July 2009, the US DOE was reporting average costs of B20 15 cents per gallon higher than petroleum diesel making it $2.69 per gallon versus $2.54 per gallon.…

    Self-propelled vehicles have been around 1672 but were not introduced to mainstream America until 1902. Older vehicles were powered by steam engines which gave way to the internal combustion engines that are powered by either gasoline or diesel fuel. Diesel fuel and gasoline both cause air pollution and also play a role in global warming. The ever increasing cost of oil along with the restrictions on greenhouse gases and environmental laws is now pressing the world to create safe alternatives to gasoline and diesel fuel.…

    The diesel engine has provided the world with cheap and efficient power for over one hundred years. The invention was first thought up by Rudolph Diesel in 1892. He wanted to create an engine that would be more efficient than the steam engine, which was only 12% efficient. He filed for a patent in Germany in February of 1892. He was granted a patent for a “Working Method and Design for Combustion Engines...new efficient, thermal engine” (History). With his patent ready, he made contracts with large companies such as Frederick Krupp and other manufacturers. Diesel created his first working engine a year later, which ran on peanut oil. That was the fuel that Diesel thought would be overall the most efficient and cost effective, it was the first bio-diesel. The engine ran at 26% efficiency, which was 14% efficient more than the steam engine, almost double. However, Diesel did not think it was enough, so he went back to the drawing board. Later in 1987, he made another model that operated at a whopping 75% efficiency (History). This was an incredible achievement because it meant that it could replace the work that steam engines do at a fraction of the cost. Nowadays diesel engine manufacturers are in competition with gasoline engine manufacturers. Diesels are making comeback to the industry because they are quieter, lighter, more efficient, less polluting and more powerful than ever. Many companies recently have been releasing cars that have ridiculously high MPG's and more power than their gasoline counterparts. The people in the United States like the idea of a fuel efficient car, but get turned off when they hear the idea of a diesel car because of their reputation of being loud and stinky. People need to be reeducated because these…

    There has always been a history of stereotypes surrounding what kind of car you drive. If you drive a small, fuel efficient, gasoline powered vehicle you can be considered environmentally considerate and practical when it comes to cost savings on gas; whereas driving a diesel-powered truck shows that you do not care about environment with your smoky, loud engine and you can usually be found at a gas station fueling up. However, are the stereotypes correct? With advancement in clean diesel technology, lower costs in overall maintenance and better fuel efficiency as well as a safer, stronger engine, there is a clear advantage within diesel engines.…
