What is diesel? Diesel is a fractional distillate of fuel oil, usually petroleum, which is used to power engines. It is a mixture of hydrocarbons that are obtained from the distillation of crude oil at temperatures of 200 to 350 degrees Celsius. Diesel produced from petroleum is sometimes called petrodiesel to distinguish it from other diesels that are derived from other sources. The main reasons for the shift in people's fuel preference are diesel's price and efficiency. Diesel fuel has a density of 850 grams per liter, which is higher than gasoline's 720 grams per liter. It also releases 40.9 mega joules per liter when it burns, compared to the 34.8 mega joules of gasoline. Another advantage it has over gasoline is that it is cheaper to refine diesel. This means that not only does diesel gets you farther on one tank, it also costs less per liter. However, diesel also has its drawbacks. One of the problems with diesel is that when it burns, it gives off more pollutants, like sulphur, compared to gasoline. Because of this, countries like the United States and some European nations impose higher emissions standards for diesel-engine vehicles. As a result, diesel costs higher than gasoline in some areas because of the added costs of complying with such standards. Despite this drawback though, diesel is still a popular choice for fuel. And with the skyrocketing fuel prices, it doesn't look like this will change anytime soon. Article Source: http://www.articlewheel.com
