With respect to the amount of energy produced per unit of volume diesel fuel is a better fuel than gasoline. So take 150 and multiply that by 378 and you get what our Norwegian friend is paying for diesel fuel.
What Is The Difference Between Diesel And Gas Cars Sun Devil Auto
The density of diesel is about 833 k g m 3 compared to 740 k g m 3 for gasoline.
Why is diesel fuel higher than gasoline. The answer boils down to explaining why the typical chemicals making up the two fuels have different activation energy barriers to combustion in air. The other is diesel needs a complicated additive to return the lubricity the fuel had before the government required sulfur be removed from it. Their gasoline counterparts will typically have their CRs lie in.
The diesel engine is much more efficient and preferable as compared with gasoline engine due to the following reasons. Taxes also factor into the higher costs for diesel fuel. 184 cents per gallon for gasoline and diesel fuel is also sometimes assessed a higher tax at the state level.
The typical diesel vehicle is bigger than the typical gasoline vehicle and damages the roads more. Demand for diesel fuel and other distillate fuel oils has been relatively high especially in Europe China India and the United States. Diesel fuel historically has been more expensive than gasoline.
Additionally Gasoline is ignited by a spark and diesel ignites directly by compression with air mixture which results in much higher heating of the substances and much more energy. A typical compression ratio for diesel engines is 18-22. Why does diesel fuel cost more than gasoline.
Demand for diesel fuel and other distillate fuel oils has been relatively high especially in Europe China India and the United States. Diesel engines are still more. The federal tax on diesel fuel is 6 cents more than gasoline per gallon 244 cents versus 184 cents.
The main reason is rising global demand but new environmental restrictions and higher federal taxes also are factors. Both gasoline and diesel fuel are produced from crude oil and therefore the cost of crude oil is the main factor influencing gasoline and diesel prices. Diesel fuel does not need Ethanol an additive that increases efficiency.
Because they operate at higher compression that requires stronger walls and pistons. This is attributed to three factors. They add more air to the combustion chamber and more air means more fuel can be added.
One is that diesel has higher road tax on it than gasoline does. In other words one gallon of diesel produces 147000 BTUs compared to 125000 BTUs of a gallon of regular gas. This gives diesel about 13 higher energy density per volume.
Diesel fuel simply packs more energy in every gallon than gas fuel which makes it more economical overall. Part of the reason diesel fuel is more expensive than gas is the total amount of federal and state taxes added to each gallon. The last tax increase came in the early 90s when diesel fuel generally cost less than gasoline.
This odd state of affairs with truck stop diesel having higher prices has not always been the case. Diesel fuel is assessed a higher federal excise tax than gasoline 244 cents per gallon for diesel vs. Here we discuss several factors contributing to the price spread.
Because diesel doesnt ignite as readily as gasoline it requires a higher pressure to self-ignite assuming both fuels are at the same temperature. In fact the situation very much was the reverse for many years past. Diesel engines have turbochargers which are pumps driven by exhaust gas.
The US government has been for years subsidizing the oil companies to keep the fuel prices artificially low it would be over 5gallon or more if this wasnt happening. In many other countries diesel fuel is still much cheaper than petrol and there are significantly more diesel-powered passenger vehicles on European and Asian roadways. How is gasoline different from diesel fuelshow more content The energy produced by diesel is higher than the energy produced by gasoline.
Per gallon or liter of fuel there is more energy in diesel than there is in gasoline. There are three main reasons why diesel fuel prices have been higher than regular gasoline prices in recent years. Growing and developing countries like India and China have placed a greater demand on diesel fuel supplies.
Gasoline or petrol for non-americans has an auto-ignition temperature about 50 C higher than diesel. At altitude it can pull in more air and more fuel and thus gets more power than gasoline engines can. Diesel engines have high torque over a narrower lower range of engine speeds They are heavier noisier for the same horsepower.
They are now quiet and require less maintenance as compared with gas engines of similar size. Diesel engines must create more compression to. Modern diesel engines have overcome disadvantages of earlier models of higher noise and maintenance costs.
Diesel fuel costs more because of the low sulfur requirements but the diesel engine burning diesel fuel is more efficient thus the motors have higher MPG. The hydrocarbon molecules in diesal are larger and able to produce more energy when burned but to create that burn a higher energy must be produced. The transition to less polluting lower-sulfur diesel fuels in the United States affected diesel fuel production and.
Mar 26 2008 There are three main reasons why diesel fuel prices have been higher than regular gasoline prices in recent years. Truck stop diesel is typically higher often much higher than buying diesel at normal gas stations. Gasoline only produces 13210 to the sixth power joules.
There are 387 Liters to the gallon. The transition to less polluting lower-sulfur diesel fuels in the United States affected diesel fuel production and. Diesel and gasoline have roughly the same energy per unit mass lower heating value about 41 M J k g.
On-highway diesel fuel prices have been higher than regular grade gasoline prices almost continuously since September 2004. Why Diesel is a Better Fuel than Gasoline. So why is diesel fuel more expensive than gasoline.
However fuel prices also reflect refining costs taxes and distribution and marketing costs.
