Jet fuel???

Attention: TDR Forum Junkies

Thanks, TDR Staff

Resale on Rams maybe not good!

They have no idea!

If #1 diesel is low grade and #2 is normal. . is there a 'Super' diesel?



Jet fuel is similar as is kerosene. Is there a 'better' more potent fuel??
 
Kerosene and Jet (which is basically kerosene and Naptha) just give fewer BTUs per pound than #2 therefore you get less power. The only super diesel is one that has additives to improve the Cetane rating of the fuel. Amoco has marketed it's "Premium" Diesel for years but since there is no regulation specifying what that means (such as premium gasoline being 93 Octane) then you may be getting "premium" and you may be getting "regular" when you purchase it.
 
Even if there was a higher grade of diesel it's unlikely your Cummins would benefit much from it without advancing the injection timing. The 5. 9 is actually designed to run best on lower cetane/grade fuel, part of reason Cummins says no fuel additives are necessary nor recommended.

what are YOU making???



Mark don't make me sell my Bike..... (I just dumped 3k into it) for money. . Wife won't let me spend anymore for a while... ... :D

not making enough... but then again what's enough?:D

Don't worry Mark you got me beat... For now, but if I catch ya, I bet it cost me much less $$$$$ than you :D :D



Darren - wish I had Mark's Money

It's not always about money;)



We'll have to get together sometime and drain a pitcher. anyone who gives and takes the razzing from me has earned it.

What about fuel oil like they use in bigger ships? How does that differ from plain old #2 diesel?



I'm guessing it's thicker, but maybe also has the potential for more BTUs per volume.

From that web site with the $10/a gallon diesel fuel... .



Eliminates SMOKE, quiets engine, reduces exhaust temperatures,



I doubt it would eliminate smoke in a truck that smokes like Jim Fuller's. Quiets the engine? Our Cummins can be quieted?



What I want to know is, how does it reduce egts? This would be a more "powerful" fuel right? So how would this lower egts, when "more power = higher egts"?



I remember Marco having problems with his MAD ECM because of the difference in celtane from Europe, so wouldn't this end up harming us here in USA then helping us?

Midnite, Most ships use what are called "low speed diesels" and burn a fuel called Bunker C (I'm talking deep draft vessels of 5,000-40,000 horses). This stuff is like tar when it is cold and is usually steam heated to around 200* F before it's injected. It has increased BTUs/pound but doesn't burn as fast as #2 and smokes alot so they normally don't burn this in port. Low Speed Diesels usually operate around 100-150 RPMs. Also, they have problems sometimes with loss of propulsion on restarts when burning Bunker C. The props are direct drive. The engine cranks in either direction to provide forward or reverse thrust so when the ship is maneuvering they swith to #2 to increase the chances of a good restart.



Jet will burn in a diesel engine just fine. Only problem is lack of lubricity with Jet or Kerosene. The pump has to have the lubrication or it will die. We used to add JP-4 to diesel in the winter for it's anti gelling, cold start qualities. But it doesn't provide the power that #2 provides. It just burns faster.
 
5% lubricating oil

The CTD owner's manual states that various grades of jet fuel or kerosene can be used on an emergency basis if "5% lubricating oil" is added to the fuel to keep the injector pump lubed. However, they never specify what lubricating oils are satisfactory. Does anyone know? I'm sure someone, somewhere has simply dumped some 5W30 motor oil in there along with some kerosene and called it good. However, what is the real scoop?
 
engine oil is probably what they are talking about. old military multi-fuel engines will run on anything flammable. engine oil was added to the tank, the amount depending on what was used,gasoline,kerosene,jet fuel and so on. the old formula for these motors was one quart of 30w which is what they used, for each 5 gallon of gasoline added. less for kerosene or jp4. these engines had a different injector pump on them. this pump adjusted fueling according to the density of the fuel. some sort of a metering built in the pump. ours of course does not have this. it would be interesting to know what cummins would recomend for other fuels instead of #2.
