In the process of manufacturing diesel is generated first and then petrol. why is petrol costlier than diesel?

Without realizing it, you basically answered your question in the way you phrased it.  Petrol costs more than diesel because it requires further steps in the refining process than diesel.

I have to admit the thought of a diesel winning does not sit to well with me, being a petrol head that is, but lets not right of the Judds just yet or even the Lister. Though having that opinion really is just me being a petrol head snob, which is wrong, the Audi team have done some great things over the past few years, which you have to appreciate with petrol power and the diesel, which has to be good in the long run of things. I actually can not believe someone has not tried winning Le Mans before with a diesel, after all reliability is a massive factor to winning this great test of man and machine and a diesel engine certainly gives this. I just guess petrol heads have to accept the fact there is nothing wrong with a diesel fuelled car, but its hard for me. Lets just hope its not the walk away that people seem to be predicting. In any case we still have the GT1's which is surly going to be a great race for the petrol heads with the Astons, Corvettes, Farraris and the Lamborghini, just hope I've got the order right there.\nThe funny thing is though I will be making my annual pilgrimage this year in a diesel car and the reason; its £120 split 4 ways for fuel apposed to the  300+ that we calculated with the price of petrol

The first process is the  finding & the mining process\nafter the mining process the crude oil have to under go a series fractional distillation processes to obtain pure oil \nThe fractional distillation processses is the important processes in the petrolium synthesis.\nWe get different products at different temperatures and conditions.

combustion of a fuel involes it reacting with air to give carbon dioxide and water...its not the by-pdts which makes the fuel good but the energy liberated in the form of heat and light,which is then used to do work

Fuel oil is classified into six classes, according to its boiling temperature, composition and purpose. The boiling point, ranging from 175 to 600 °C, and carbon chain length, 20 to 70 atoms, of the fuel increases with number. Viscosity also increases with fuel oil number and the heaviest oil has to be heated to get it to flow. Price usually decreases as the fuel number increases. No. 1 fuel oil, No. 2 fuel oil and No. 3 fuel oil are referred to as distillate fuel oils, diesel fuel oils, light fuel oils, gasoil or just distillate. For example, No. 2 fuel oil, No. 2 distillate and No. 2 diesel fuel oil are the same thing. Distillate fuel oils are distilled from crude oil. Gas oil refers to the process of distillation. The vamia oil is heated, becomes a gas and then condenses. It differentiates distillates from residual oil. No. 1 is similar to kerosene and is the fraction that boils off right after gasoline. No. 2 is the diesel that trucks and some cars run on, leading to the name "road diesel". It is the same thing as heating oil. No. 3 is a distillate fuel oil and is rarely used. No. 5 fuel oil and No. 6 fuel oil are called residual fuel oils or heavy fuel oils. However, since No. 6 is far more common than No. 5, the terms heavy fuel oil and residual fuel oil are sometimes used as synonyms for No. 6. They are what remains of the crude oil after gasoline and the distillate fuel oils are extracted through distillation, but No. 5 fuel oil is about 75-80% No. 6 and the rest is No. 2. No. 6 may also contain a small amount of No. 2 to get it to meet specifications. No. 4 fuel oil is usually a blend of distillate and residual fuel oils, such as No. 2 and 6, however, sometimes it is just a heavy distillate. No. 4 may be classified as diesel, distillate or residual fuel oil. Residual fuel oils are sometimes called light when they have been mixed with distillate fuel oil, while distillate fuel oils are called heavy when they have been mixed with residual fuel oil. Heavy gas oil, for example, is a distillate that contains residual fuel oil.\n\n\nTable of fuel oils \n(Name ,Alias, Alias Type, Chain Length )\nNo. 1 fuel oil No. 1 distillate No. 1 diesel fuel Distillate 9-16 \nNo. 2 fuel oil No. 2 distillate No. 2 diesel fuel Distillate 10-20 \nNo. 3 fuel oil No. 3 distillate No. 3 diesel fuel Distillate  \nNo. 4 fuel oil No. 4 distillate No. 4 residual fuel oil Distillate/Residual 12-70 \nNo. 5 fuel oil No. 5 residual fuel oil Heavy fuel oil Residual 12-70 \nNo. 6 fuel oil No. 6 residual fuel oil Heavy fuel oil Residual 20-70

In much of Europe diesel powered automobiles are very common and account for more than 50% of sales. This may be because of the very high fuel prices in Europe and the fact that many small European diesels get exceptionally good mileage. US EPA rates the Volkswagen Jetta at 46 mpg highway, and 38 mpg city. Some owners report even better mileage. In the US diesels never really caught for cars because they were noisy, smelly, required very frequent oil changes, and had a higher initial cost than a gasoline engine. I personally suspect the main reason US car makers never pushed diesels is because it takes higher-precision manufacturing to build a diesel engine compared to a gasoline engine, so they cost more to build. Diesels often last much longer than gasoline engines so this might have been another reason US manufacturers didn't like them.\n\nThe other strange phenomenon that has happened recently is that in the US diesel fuel is now more costly than gasoline. This has not always been true, and seems to be related to current lack of refining capacity in the US for diesel fuel.

They are basically the same price (4 quarts = 1 gallon). Any price variation from there would have to do with the process it takes to refine gasoline. Although they are both petroleum products, they are not manufactured in the same way.

Natural gas comes from the ground like oil, except that it's a gas and not a liquid. There are pockets of it all over the world (again, similar to oil).\n\nIt produces electricity similar to a car engine. Some engines are designed to run on natural gas instead of gasoline. Once the engine gets running, it is hooked up to a generator which produces electricity.

No. It just wastes more gas, builds up carbon deposits in the cylinders quicker, and tends to make the engine an oil burner.  There are many possible reasons why his is faster, but worse than optimum combustion isn't one of them.

For starters, if you don't have a diesel motor, you would have to change motors.  Then there are things that you have to do to the diesel motor to get it to run on biodiesel.

How brief do you want it? This is as brief as I can think of; Gasoline engines ignite the fuel with an electric spark. Diesel engines ignite the fuel by compressing the fuel. Compression causes heat and diesel engines compress the fuel to it's flash point although most diesels also have an electric glow plug for initial firing up. A glow plug is a strip of metal that heats up from the battery and creates enough heat in the firing chamber to initiate the internal combustion process.

cost to produce the fuels, amount of energy needed to make the fuel, newtons law is still in effect, nothing free comes out of nothing, it still cost energy  to make energy, the problem is the the cost is still higher than the final product ( combustion ) , and is also reflected on the relatively high price, even if it did come down we replace one type of pollution for another, of course the farmers are rooting for it as it will be a cash crop if it takes off, the same can be said for the hybrids, they cost more to produce in both materials and non renewable parts ( changing out those batteries will be mega expensive ), ect.. they are not the ultimate recycling dream the green groups like to champion them as they are, they simply do not want any rain on their parade

Fossil Fuels have been more valuable because of the war at Middle East which is centered at Iraq which holds a lot of oil (which is a main fossil fuel) at Middle East. Government have made solar panels, hydroelectricity dams, and wind turbines to reduce the use of fossil fuels. Fossil Fuels have a negative impact on the environment because it causes global warming.

If you mean greatest source as in overall production then solar shall be your answer hands down.  If you mean, greatest in the sense of coming from one place as a power plant, then one should answer fusion. And we should not discount used vegetable oil diesel vehicles.  The smell of cooking french fries on the highway is one generations to come shall savior..he..he.

they are a four stroke just like gas engines but gas engines are spark ignition and diesel engines are compression ignition, that is whey there is no spark plugs the heat from the piston compressing the air and fuel mixture gets to a point of explosion and boom down goes the piston and over and over it goes and away you go (Intake compression, power, exhaust)

Bio diesel is pretty easy to make.\n\nAll you need is vegetable oil, methanol and lye.\n\nI haven't made any, however you need to make sure there's no water in the oil because it will gel up.\n\nWatch out though, the lye is highly corrosive and will burn your skin and the fumes can kill your lungs.\n\nBest bet is to have someone who knows what they're doing do it for you, or buy some already made bio-diesel.

We find petroleum products in every area of our lives. They are easily recognized in the gasoline we use to fuel our cars and the heating oil we use to warm our homes. Less obvious are the uses of petroleum-based components of plastics, medicines, food items, and a host of other products.\n\nPetroleum products fall into three major categories: fuels such as motor gasoline and distillate fuel oil (diesel fuel); finished nonfuel products such as solvents and lubricating oils; and feedstocks for the petrochemical industry such as naphtha and various refinery gases. Demand is greatest for products in the fuels category, especially motor gasoline.
