Both are refined from the same thing, Crude Oil. The difference is that gasoline (petrol) and diesel have different boiling points. Hydrocarbon molecules of different lengths have different properties and behaviors. For example, a chain with just one carbon atom in it (CH4) is the lightest chain, known as methane. Methane is a gas so light that it floats like helium. As the chains get longer, they get heavier. The chains from C7H16 through C11H24 are blended together and used for gasoline. All of them vaporize at temperatures below the boiling point of water. That's why if you spill gasoline on the ground it evaporates very quickly. Diesel will take allot longer to evaporate. Next is kerosene, in the C12 to C15 range, followed by diesel fuel and heavier fuel oils (like heating oil for houses). As the chains get longer the boiling point goes up. So diesel has a higher boing point that petrol. Diesel must be compressed to a higher extent before is explodes. That is why a diesel engine has no spark plugs to ignite the fuel. The ignition is accomplished by compressing the fuel. All of these different substances come from crude oil. The only difference between petrol and diesel is the length of the carbon chains.

What is the mileage for Ford vehicles?
Ford sedan will give 14-17kmpl for petrol and for diesel 17- 23.5kmpl SUV will gives 7 to 12 kmpl for petrol and diesel
The main difference between the internal combustion engine and the diesel engine is that the diesel engine?
The main difference between diesel motors and petrol motors is in how the fuel is ignited. Gas engines use spark plugs to ignite slightly compressed fuel molecules. Diesel motors use extreme heat and compression to cause the fuel to ignite. For example a petrol engine may have an 8-1 compression ratio and a temp. of 5,000 degrees in the combustion chamer a diesel engine will have a 15-1 ratio and around 15-20,000 degree combustion chamber give or take depending on the engine design. In the end there not that diffrent.
Is petrol engine or diesel engine better?
AnswerIt's more a question of being different than one being outright better than the other. Diesels have the possibility to give better fuel efficiency, but tend to run rougher for instance. And for the same engine size/weight, a diesel will have a lower peak power output.So, what's the "better" engine will depend on the engineering requirements and you preference.AnswerA petrol engine runs on petrol and a diesel engine runs on diesel- this is the basic difference between the two. But yes, jokes apart there are many more differences too. In a vehicle having a similar mass a diesel engine is more efficient most of the times than a spark-ignited petrol engine which results in the diesel having a lower fuel consumption and a cost effective solution for the consumer.
How much is a jeep?
Depending on which part of the world you're from and what specific features you're looking for will give you a range of prices. The biggest difference (where I come from) is between diesel and petrol. With petrol our road user charges are part of the price at the pump. While as diesel you pay less at the pump but get taxed per mile half annually. Typically for a late 2000's Jeep Wrangler over here with an average set of features and petrol, you'd be looking at around $20,000-$25,000USD for a decent one. Hope this helps.
What is the difference between diesel and petrol cars?
Diesel can give much better fuel economy (miles per gallon or kilometers per liter) than petrol but the downside is that diesel engines cost more to manufacture than petrol engines. So a petrol-engined vehicle usually costs less money to buy than a similar make and model that has a diesel engine. The design of a petrol-burning engine is different from that of a diesel engine: a petrol engine burns petrol (called gasoline in the US) which is ignited by a spark plug. A diesel engine burns diesel fuel which self-ignites when compressed.
Is 16V dohc engine is petrol or diesel?
Yes, its a hybrid petrol/diesel. put whatever you want in it. Give more details if you want a non-smartass answer. What type of vehicle, what size engine v8, straight L6, H4, I4, What WHAT!!
Why do many cars have diesel engines when petrol gives a better performance?
Some cars have diesel engines because diesel engines give more mileage and diesel is cheaper than gasoline in some countries. In the UK diesel fuel costs more than gas but, because diesel engines give much better mileage (miles per gallon), people are still happy to pay more for the diesel fuel if they run diesel vehicles. Diesel engines last much longer and have much better torque at low revs than a petrol engine.
What is difference between torque at Nm equals 120 rpm equals 1800 and Nm equals 120 rpm equals 4000 give detail better as performance and load capacity in petrol engine?

What kind of oil should be used on a 2001automatic Honda civic?
a special mix of diesel and petrol. Exactly 200 ml of petrol and 700ml of diesel every 900mls. Then you should add some nitroglycerine to it and give it a nice shake so provided you survive the blast, you can pour that into the car.
Why do diesel engines give more mileage than petrol engines?
1) Diesel contains more energy in it than Petrol 2) Diesel engines can run much leaner air fuel ratios than petrol without engine damage, due to compression ignition there are no pre-ignition problems 3) Pumping losses are much lower because the throttle is always wide open 4) Compression ratio is much higher which leads to better thermal efficiency than petrol.
What are the advantage of CNG over petrol and diesel engine?
CNG engines create less polution than petrol and diesel engines.As it is using compress natural gas power develops more than the others and also develops more torque in the engine.which leads to give a lower fuel consumption.
