    It's diesel fuel or gasoline; Not diesel gas DUH. You had to fuck up somehow if you are even asking this question, so what did you put in the wrong fuel??? [​IMG]

    diesel has bad smelling "stuff" in it so you won't accidently put it in a gasoline powered car.

    Diesel comes out of the green nozzle.

  7. Diesel is a mid-refined product, meaning that it takes less to produce it than gasoline (petrol), which is a high-refine.
    Diesel has about 11% more BTU than gasoline, which accounts for some of the difference in mileage between diesel engines and petrol engines. Diesel has more BTU because it is refined less, meaning it has more of the power potential available from the crude oil. Petrol has had more power potential refined out of it.
    The reason that petrol is still more popular in the USA for passenger car usage is that it was originally simpler to build a lower compression engine and ignite the mixture with a spark than to build a high-compression engine and the attendant injection apparatus. Also the extremely poor GM passenger car diesels of the eighties pretty much killed the idea until those who remember the 5.7 Oldsmobile diesels all die.
    The reason diesel is approaching parity with petrol in Europe is due to several factors, some of which are the power available (11% MORE, recall), the lower specific consumption of the fuel, and the new common-rail design of injection, which brings the diesel up out of the dark ages, making more power yet, and using less fuel. Turbocharging hasn't been a bad idea, either.

    But seriously, what did you put diesel in, and where did it stop running??

    really guys, we shouldn't jump to conclusions. maybe he just needs the info for the class science project. [​IMG]

    what i want to know is, if more refining takes away the btu(is that the same as octane?), why does the good stuff cost more than regular? regular should be more refined and therefore more $$$. i was once told by an oil company insider that the different grades cost no more to produce, yet there seems to be a 20 cent difference between the grades.

    Didn't you read Road Rocket,man?? The Pooch told Dick to siphon gas out of the car or truck. Dick didn't listen, and siphoned "gas" out of the tractor! When they tried to getaway,the car stalls, and they get caught. Don't be a DICK!! [​IMG] Sparky

    Chemically, Diesel fuel is a wax, and Gasoline is a mixture of solvents.

    Because some people will pay $0.20 more for something that is "premium"

    even if they do so only to keep their engine from knocking.

    If you look you answered your own question "more refining" = higher cost. BTU not the same as Octane.

    [/ QUOTE ]Nope it takes higer grade componets to get the oct up to 91... I worked at Mobil Oil and blended the diffrent grades to specs. Before I left it took 7 diffrent componets to make supper. Diesel cam right from the towers and only too a couple of additives before shipment. When I quit they were getting ready for a low sulfer diesel that should be out soon..... So anyway what this guy do gas to diesel or vice versa [​IMG]

    ok probably shoulda cleared up what the post was about before i posted but no im not dumb i didnt put diesel in my car or vice versa or anything like that i was bs'n w/ one of my buddies and was thinking about diffrent ways to inject flamethrowers he asked me about diesel and i just kinda stared blankly at him because i had no idea so i figured id see what major difference there was as far as how flammable it is jeez i didnt expect to get reemed that bad

    It isn't as flamable as gas is. You can pour it on the ground and throw matches at it, and nothing happens. You can ignight diesel, but you have to atomize the hell out of it, and use a fat spark. For flame throwers, I'd stick with gas.
    My truck has a 17.5:1 compression ratio, and no spark - diesel lights just fine under those conditions.

    This looks like the perfect opertunity to talk about dieseling, run on, preignition (which is a funny term because it's actually POST ignition). From what I've learned about this subject, That's what Octane ACTUALLY does, reduce the chance of burning WITHOUT spark causing a dieseling effect, where Gas actually burns with compression only. Heres My Question, WHAT are the conditions of any Gasoline engine that would cause this effect in the first place making you NEED the higher octane gas. Seems to me the BETTER built the engine (good rings, no blow by, tight seal...etc.ect.) contribute to the problem! Again I know what it is, I know how to cure it (Higher Octane Fuel) Whats The CAUSE?

    Actually there is a difference in these two forms of abnormal combustion.

    Detonation can be caused by:
    Lean fuel mixture
    Fuel octane too low
    Improper ignition timing
    Lugging
    Carbon deposits
    Excessive milling of heads or block, which will increase compression ratio.

    Pre-ignition ....actual ignition before its intended time...can be caused by:

    Carbon deposits that remain incandescent
    Spark plugs too hot a heat range
    Spark plugs not firmly seated against gasket
    Detonation or the condition leading to it
    Sharp edges in combustion chamber
    Valves operating at higher than normal temperature because of excessive guide clearance or improper seal with valve seats.
    Overheating
    Ignition crossfiring. Induced voltage in spark plug wires that run parallel to each other for long distances.

    I had heard that diesel was somewhat of a bi product left over from the gasoline producing process. And the oil used to pay disposal fees until someone found out a use for it. I'm a huge fan diesel engine torgue torque torque. It also cleans out cumbustion chamber residues if poors through a carb. just stop when it starts to choke.

    I once saw a woman crying at a gas station pay phone. I asked what was wrong, and apparently her husband was yelling at her on the other end. She pointed at the big truck pulled up to the pump with a huge tank on the trailer with a gas nozzle in it. She had accidentally filled the farm fuel tank with Regular instead of Diesel. [​IMG]

    Only about 500 gallons though...

    Your bio lists your occupation as "mechanic". Where the hell did you go to Tech. school? I'm guessing you are a young kid and your occupation is "student".

    #2 Diesel fuel is commonly used in large trucks, tractors, ships, bulldozers, and industrial equipment. These are heavy-duty applications that need to move heavy loads at a relatively slow speed. Someone may correct me on this but #1 diesel fuel is commonly called Kerosene or home heating oil. It burns easier and cleaner than #2 diesel.

    I wouldn't even try kerosene in a flamethrower. If you could get it lit properly, it would probably put out some nasty black smoke, be dangerous and un-cool.

    The Fuel Octane to low issue is the one I'm addressing I guess. Is it to low because the compression is TOO GOOD?

    #2 Diesel is what comes out of the green handle pump at the gas station - it goes in tractors, as well as *all* diesel burning cars & trucks.

    Nope. #1 diesel is thinner than #2 and used in really cold climates because #2 will turn to a semi-solid when it gets real cold. Don't run it unless you live in Alaska in the winter, and if you did, they'd be selling "Winter Blend" diesel, which is thinner than #2.

    Heating oil is the same as #2 diesel, but it has a die added to it (so the inspector can see if you are running heating oil instead of #2, and avoiding the taxes).

    It works just fine, but it requires good atomization and a fat spark. Yes, there's a lot of black smoke, but so does burning raw gas.
    See the black haze in this picture? It's from a gas flame thrower.

    I saw flame throwers in action. My army unit still used (trained) them until 1989 (I wasn't trained on them so I don't know the specifics). And yes, they were extremely smoky and disgusting. I remember a guy coming back from an exercise, where he had to jump thorugh a winow of a concrete ruin that had just been flamed and got the skin burned off of his hands because he used his hands to push off the widow sill.

    The flame oil used in the throwers was actually closer to diesel than to gas. The flame throwers use a ignition cartridge in the "barrel" to start the flame.
    Regular gasoline would have been much too dangerous for the operator.
    good times, good times...
     
  27. I thought you could make Krispy Kreme donuts with diesel. Or was that the banana/peanut butter sammiches from Graceland?

    one thing to mention is that at some gas stations you are buying the same gas at some of the different octane levels.they just mix it.like they will take 92 out of that tank,and 89 out of its.meet in the middle to make 90.im sure it would depend on how there tanks,and octane levels are set up.its just smart for them to do this soo they dont need another tank.

    Old tractors had a 2 compartment fuel tank. One held gasoline the other kerosene or "coal oil". Started the tractor on gasoline once it warmed up turned switch it then ran on kerosene, which was much cheaper and maybe easier to get back in the early 40s.
