What’s The Difference Between Jet Fuel and Car Fuel?


What’s the deal with airplane fuel? Have you ever wondered if you can you put
jet fuel in a car and make it go faster? Like, a rocket car! Well, the answer is yes and
no, because even though at the core, jet fuel and car fuel are similar, they are actually
so, so different. Most cars and jets are powered through some
sort of combustion. Cars have an internal combustion engine and jets gas turbine engine.
Which means they both rely on a heat source or explosion to power the engine. In most
cases, this requires some sort of combustible fossil fuel, which of course is derived from
oil. But that is where the similarities stop. To understand the differences between jet
fuel and car fuel you need to understand oil. The black slick stuff that comes out of the
ground. It contains aliphatic hydrocarbons. In other words, molecules of just hydrogen
and carbon. But depending on how many hydrogen and carbon atoms there are, the molecules
behave differently. When a hydrocarbon chain has only one carbon
and four hydrogen, it’s super light and makes methane. As more atoms are added to
the chain, naturally the molecule gets heavier alters its properties, becoming another gas.
So for instance, two carbon atoms and six hydrogen atoms make ethane (C2H6), propane
is C3H8 and butane is C4H10. The C7 to C11 range make gasoline. Airplane
fuel is derived from much heavier chains, kerosene, in the C12 to C15 range. These two
fuels actually have similar properties but one of the key differences between gasoline
and kerosene is their flash point. The main reason airplanes use kerosene is
safety. Kerosene has a higher flashpoint then car gas, which means it takes a higher temperature
to ignite kerosene. This is important when you have a lot of it and it’s around a lot
of people, like say a major airport. Kerosene is also easily transported and is readily
available around the world. Also, kerosene can stay in liquid form longer
at low temperatures, which is important when you’re flying thousands of feet in the air
when temperature can reach 34 degrees below zero Celsius or more. Now there are two main types of jet fuel depending
on where you are in the world, Jet A’s and Jet A-1. Jet A is available mostly in the
US and has a freezing point of −40 °C, while Jet A-1 is used in the rest of the world.
It has a lower freezing point of −47 °C. Frozen jet fuel would be disastrous. And to make quality jet fuel, additives are
injected to help stop things like static build up, which can create a spark, an anticorrosive
agent, a de-icing agent, and even an antimicrobial agent to stop bacteria and fungus growing
and clogging the engine. Obviously, the gas you put in your car doesn’t need all of
this. The bottom line is, car fuel and jet fuel
are made differently from the start, and your car can’t run on kerosene and doesn’t
really need to be prepared for such low temperatures. Also, jet fuel is super expensive, often over
$4 a gallon. But even after all that, there is one instance
jet fuel and one type of car fuel are actually kind of similar. Turns out jet fuel is a lot
like diesel. So much so you can actually power a diesel powered truck with it. (although
apparently you might want to add a lubricant). But if you put it in your regular car, it
would be just like putting diesel in it, it just kind of stalls out, because of the way
diesel engines and gasoline engines differ. Diesel engines compress the fuel at a different
ratio than gasoline engines to get the fuel hot. So your car’s gasoline engine just
won’t get the jet fuel hot enough to spark. But it still could damage your engine. BUMMER.

  1. I designed a pulse jet engine that runs off hydrogen and oxygen using a Tesla Turbine array and Tesla Valves for ultra high performance compression and high output energy production to power complex peripherals like personal safety and automated guidance, with as few moving parts as possible.

    It can produce enough thrust to act as a lifting engine to convert any existing small passenger vehicle into a flying vehicle with simple rally kit and roll-bars already commercially available to reduce weight. The pulse jet can power a massive generator. Enough to easily power hovering take-off and landing maneuvers when attached to a small passenger vehicle, as well as long distance container transport.

    I could power the future with Sea Water and solar panels. Problem is no one wants a future. They want a now.

  2. Can you make a series of video or a video in Metallurgy…. like types of steels used in automobile and aluminium​, titanium etc…???

  3. The term "gas turbine" is misleading to some. Some will think it uses gas when they hear that. It's a "gas generator".

  4. Kerosene is virtually heating oil which is also used as "Alpine Mix" for diesels in areas above the snowline.
    Jets would run quite well on diesel or distillate apart from the fact that it would freeze at altitude. A bit of kero' wont hurt your diesel.

  5. I think you can put jet fuel in a diesel truck and run it no problem although it won't make it any faster (obviously). Heating oil, Diesel fuel, and Kerosene are all the same. Jet fuel is very similar to the 3 I mentioned because it is Kerosene with additives.

  6. apparently jet fuel can bring down three buildings from two planes crashing into them. Even though as you said it doesn't burn anywhere near hot enough to even melt steel.

  7. Why does everyone assume all cars run on gasoline, when many run on diesel including mine. Also Jet fuel, Kerosene, and diesel are all in the same fuel family the only difference is the oil lubrication content. kerosene can be added to diesel to keep it from freezing in the winter. Jet engines can also be run on diesel fuel in an emergency as long as the fuel remains warm.

  8. Did she say gasoline engine wont heat the jet fuel hot enough to spark?? WTF well…. they dont know how a gasoline engine work lol failed research here!!! boooooooooooo

  9. Full of shit sweet heart.
    Mix one litre of hydraulic oil with 25 litres of kerosene and you got some cheap cheap diesel sugar.And no duty to pay.
    Dumb bitch.

  10. A great science presentation… the comments below are by the same sort of people I went to school with 50 years ago. People who failed to follow science class and are merely offering their OPINION, as opposed to offering their KNOWLEDGE. Science SUCKs! Because when your Science is WRONG. You are truly SCREWED.

  11. I managed watching the video for 45 seconds… What an annoying voice. The exaggerated laughing is unbearable…

  12. This video is fine, but it’s misleading as it ignore AVGAS completely, which is very much like automotive fuel.

  13. I wanna smack her. Why does everyone have to present things the same way of talking its so fucking annoying.

  14. A diesel Jetta can run on jet fuel. All the mechanics do it when they defuel the airplane, since you can't reuse that fuel in the aircraft they just put it in their cars

  15. Ummmnnnn…. I still don't get it. Your English is super fast. My head can't process it. So please re up in more simple and slow English version. Where did you ler…. Oh ummnn… you are American, obviously u speak English. OK. JUst lower the speed of your engine so that I can compile it in my speed. Thank you in advance. C yaa…
    And you are cute.

  16. We are finding out that large airplane and military jets use free energy turbines. They use compression of the air to create more energy than input and looks like it doesn’t run on any liquid fuel

  17. I don't even need to watch the video to know the answer to this so I'm commenting first to see if the bitch gets it right or not. Jet fuel is nothing more than kerosene. There is nothing added to jet fuel to make it hotter or somehow more combustible than regular kerosene. They do add coagulants to it so it doesn't vaporize into an explosive cloud during a crash… That's it.

  18. Jet fuel is basically kerosene, which is basically diesel fuel which is basically home heating oil. Jet fuel has different additives so it won't thicken up at extreme cold. The summer diesel fuel is different than winter diesel. Diesel fuel is basically very light refined oil with very specific additives. All the North American diesel sold for road use is Ultra Low Sulphur or ULSDiesel. It burns cleaner than the older LSD, but the older stuff has more energy or BTU per gallon, so you get 2 to 3 percent better MPG with the older grade which isn't readily available anymore except for industrial use or farms or construction sites. It's illegal to use LSD in a newer vehicle for the past 11 years. By the way, Biodiesel of 5 percent bio content or more, will burn cleaner than ULSD because the bio portion has some hydrogen in it, whereas without the bio portion, ULSD has no hydrogen. Using more than 10 percent bio in the diesel fuel, shows a drop off of power, so fuel mileage with 20 percent Biodiesel won't be as good as 10 percent Biodiesel. Some cross country truckers spend $10,000 a month or more for fuel, so MPG is critical. That's why Biodiesel isn't as popular as the tree huggers want it to be, because it will cost at least $500 per month or more using 15 percent Biodiesel than normal ULSD because the bio stuff doesn't get as good power or MPG. I did cross border driving since 2003 from Toronto to the eastern U.S. seaboard and it was almost impossible to find Biodiesel around NYC or NJ or NH or PA. The mid west is an easier place to find it among the farm community who grow the soybeans used to make the bio portion.

  19. Many British and Americans, that worked in and around the twin towers, flew on the Concorde, and when the towers fell, they could no longer keep the concorde going, so it was ended in 2003. The French Concorde crashed in 2000. So much Jet fuel involved in all that.

  20. What's that? Burning jet fuel within a furnace like environment where the net amount of heat energy being released from the jet fuel is not equal to the net heat energy being released from the mangled building/aircraft comtraption (basically acting just as a furnace). Therefore, an excess amount of heat energy is being built up in the building causing the steel beams to reach temperatures higher than the temperature at which jet fuel burns at in an open environment.
    But heyy….. who's going to believe such common known science that like people in the times before the mediaeval era knew about. Like making Iron/steel swords, arrow heads, spearheads, bolts, helmets, armor etc.. It's not like they exploited this crazy phenomena that they discovered thousands of years ago; yet we have smartphones and all the information at put fingertips everyday and at all times and we still give into our own cognitive biasis' and only look into evidence that we believe supports our hypotheses etc. (Look up the entire list of cognitive bias list on google maybe?)
    When that's the way people behave and accept that is normal behavior, the further back we as intelligent species continue to fallllllllll…….. 🙌🙋‍♂️

  21. My dad said that he used to put jet fuel in to his motorbike, when properly adjusted it was waaay better than any kind of petrol he said and a lot more fun to drive. That was many years ago, but the fact is that bike wasn't designed for the jet fuel -)

  22. 2$ for gallon in Iraq ….and yes jet fuel cant melt steel beams it has to be thermit like ''rail welding''

  23. In my first car in 1986…it was a Toyota Corolla 1974….I put 3/4 gas and 1/4 racing blue in it. That thing would do 120 mph downhill in a hurricane. Actually did do 120 mph…but it was down a large hill on our bypass…no hurricane though.

  24. Some manufacturers of small aircraft have begun making Diesel aircraft. The idea is that Jet A is actually about $1 cheaper per gallon than AVGAS. Most piston aircraft run on AVGAS. The aircraft diesel engines have oil reservoirs for lubrication. Just like with anything else, the downside with diesel engines is that they cost a lot of extra cash.

  25. also Diesel engines don't have spark plugs since the high compression of the Diesel engine combustion process causes the diesel fuel to ignite instead of an electric spark in regular engined cars. That is also why Diesel engines are also about 20 percent more efficient producing less CO2 as a result, but also producing a lot more NOX as a byproduct.

  26. I don't need to watch this; I already know the answer: Jet fuel is KEROSENE! That's right; it's a form of kerosene, not gasoline, which is why the airlines switched to jet and turboprop aircraft in the 1950's and 60's. Piston engines needed high octane [read: expensive] aviation gasoline. A turbine [jet] engine can run on most any flammable liquid. Back then, kerosene was in low demand and dirt cheap.

  27. Avgas 100LL runs great on old mopar big blocks [its not jet fuel it’s just leaded high octane gas made for piston aircraft such as Cessna planes].

  28. Diesel engines don't compress fuel, liquids dont compress, (or hydraulics woundn't work), Diesel engines compress the intake charge into a very small area, getting it very hot so the fuel that is injected explodes spontaniously. Gasoline engines use lower compression ratios, and rely on spark plugs to ignite the fuel/air mixture.

  29. I saw your cringey fake looking ass thumbnail and I clicked on this video solely to downvote it and to tell you I hope you die of AIDS.

  30. well umm ones Av gas and ones petrol, did you know some motor bikes on the speedway use Av Gas (not allowed to use on the road at least not in Aus anyway)

  31. Okay I got a question there's an idiot has been saying that jet fuel is made from fuel from petroleum bottles and that this petroleum fuel when released from the Jets causes a plastic to be created and spray all over everything now I know I see Chemtrails but I just can't believe that that this is true
