Diesel / CNG discuss

Yes currently it break even, wait till diesel is back over 4.00&$ gallon that when it pays off.

It takes x amount of energy to move said weight from point a to b. When diesel gets back up where it has been in cost the past 3 -4 years then it is cheaper to move that weight down the road with CNG as a supplement to diesel.

I have been running it for 5 years now and it's .40 more a gallon now than when I started.

It's just like everything else if it was never tried out it would never be know. So to me it has been worth it most of the time. If someone doesn't want to try it then don't. It's called alternative fuels. Not being azz just saying.

Yes, it is mostly break even at this point. Its why dedicated CNG vehicles are they way to go, or get a digital controller from Deluca and run 90%+ CNG. Basically just giving it enough diesel to lite things off.
 
Truly my thought is LNG is where I would like to go or get to with my truck. UPs trucks are running it I see them all over 270 loop in Columbus.

Or you can be like the King family, where you buy well gas for $1 over MCF trade value and compress it for next to nothing! That's where you save, they only have one car that runs on gasoline! Hell his race car is CNG LOL

Sounds like you're the one scared?

Do you know how long people have been supplementing their diesel vehicles? If you inject mass amounts of CNG where it is rich enough to ignite under only compression, maybe you'll have issues but I doubt it. Thing is, CNG has a very narrow AFR window to where it will ignite. The fuel is "timed" to whenever we decide to inject the diesel.

And what does propane have to do with this? And what was the instance where you had trouble blowing something up?

read the thread guys, i gave you how to find it on here, this has been well covered, if cng or propane are being introduced into the engine with the air, it is an untimed fuel, the exact opposite how your diesel engine is built to function. If you want your exspensive high compression diesel engine constantly pre-igniting that's you and your engines thing, ass kissers LOL

I will say this if you do not know the difference between PROPANE and Natural gas or CNG ( COMPRESSED NATURAL GAS) then you are the DUMB ASS!
 
westport, google westport cummins or westport ford, they build spark ignited cng engines, their engines burn cng that is injected by fuel injectors, then that fuel is ignited by a spark, is that how your system works, genius
 
Do you know what timing I am running? Where is the link in the post? Where I went back and looked again its not there, what is the difference in Propane and CNG please do answer without google involved genus!
 
your logic that you are trying to sell is unsound. I don't care if you blow your motor or think you are saving big bucks. The suggestion for others to google and read at westport cummins, to understand how a company that actually builds cng fuel systems to convert diesels properly is obviously lost on you.
 
Whom was I trying to sell anything to? This post was a question yes! I have offered nothing for sale to buy or any such bull sh!t, you on the other hand have nothing from personal experience to add other than what you read on Google so go blow smoke up yours or someone else's ass, I couldn't care less for your inexperienced opinion! Where is the CNG in the link you provided??????????

I'm not sure what crawled up your ass, but it phukin smells bruh.

If this fuel delivery system burns so uncontrollably, then how does it work so good? Explain to me that when a vgt equipped engine goes into turbo braking mode, and the CNG is left on by accident, that nothing adverse happens? The fuel isn't burning because there's no diesel to lite off the CNG. The AFR of the CNG being injected is so lean, it won't burn on its own, until there's a fire starter. Being as even when running 90%+ CNG you still need at least a pilot injection of diesel to get things going.

Want to know why Cummins doesn't do bi-fuel? Because its useless to have an OEM engine with an expensive CRD injection system just to run it on CNG. Much easier to have an ignition system. Not to mention, every possible mix of diesel/CNG percentage at every load/rpm would have to be epa certified.

I have noticed in my short time exposure with alternative fuels, there's some people that always want to argue, and to try anything other than gasoline is a waste.
 
turbo X is designed to compress Y amount of air/oxygen into your diesel engine, add cng: now you have turbo x compressing or adding air/oxygen and cng creating is an imbalance of the air/fuel mixture. now you have two different fuels in the cylinder and less oxygen than you would normally have just to fully burn the diesel never mind the cng as well. are you jackasses trying trying to sell us on bigger turbos? so we can have expensive Hindenburg trucks like yours, weighed down by cng tanks, hoses,regulators and all the other crap... clueless wonder you are trying to sell your BS logic
