The Diesel Fuel

With the increasing price of fuel today, people are looking for the cheapest fuel available. This distinction goes to diesel fuel, which costs less than unleaded and premium fuel. As a result, more and more people are buying cars that run on diesel. In countries where fuel consumption is high, diesel fuel is an extremely popular choice for powering cars. People buying new cars nowadays have to take fuel costs into account, which is the main reason why more people are asking for cars that run on diesel when they enter the showroom. In addition, because of higher fuel costs, people are turning to the use of motorcycles and scooters, which usually run on diesel fuel. This means that countries like China, which has millions of scooters and motorcycles on its streets, continue to receive and consume more diesel fuel.

So what is diesel? Basically, diesel is a fractional distillate of fuel oil, usually petroleum, which is used in engines. It is a mixture of hydrocarbons obtained from the distillation of crude oil at temperatures of 200 to 350 degrees Celsius. Sometimes, diesel produced from petroleum is called petrodiesel to distinguish it from other diesels that are acquired from other sources.

Diesel's price and efficiency are the two main reasons for the shift in people's fuel preference. Diesel fuel has a density of about 850 grams per liter. This 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 costs less to refine diesel. This means that not only does diesel has better mileage, 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.
