I'm working on installing a CNG compressor in my garage and start running my gasoline vehicles on Natural Gas. Current prices for NG are .80 per therm, which is about half what I spend to buy propane to heat my house. So, once I have everything converted, I expect to run my daily driver car for less than $2 GGE. Gasoline engines can run on straight CNG. Makes complete sense to drop gasoline to me. Not to mention, we have enough NG in the ground to supply all the homes and vehicles in the US for over a 100 years. Bye bye OPEC!

Now, my questions start with diesel CNG kits. Diesel engines will run on straight CNG, but they need diesel fuel to help with ignition and diesel fuel helps keep things lubricated. Obviously not as well as the old good fuel.

I know Drugs Kill, this is why I never did propane. But how would I safely setup CNG to run in my PowerStroke? Obviously going to need some special tunes, and I may not be able to tow heavy with CNG. Who knows how to tune gas safely?

Also, 3 - 12 GGE tanks would fit under my CCLB easy, 4 if I removed the stock long tank and installed an Excursion tank where the tires mounts. 3 tanks would hold close to what the stock tank does. If I needed more, a 25GGE would fit in the front of the bed, I just don't want to give up bed space.

Ok, back to my original question, does split shots in the 7.3 mess up any mileage gains by the pre-ignition diesel fuel charge burning the CNG early? It seems single shots would be a requirement for safer operation?

Yes.

You need to run single shots w/ conservative timing and generally on the low hp side. Slowish nozzles wouldn't hurt either.

I think your ideas are awesome and I hope you succeed.

Ok,

How conservative on the timing. I'll either need to buy a tuning program to allow tuning myself, or who should I be talking to &/or working with?

I read a few years back in Diesel Power Mag where a guy had outfitted his truck with CNG injection. If I remember right he was injecting the whole time it was running, which made the diesel burn more efficient. I know, same theory behind a propane kit. He was getting some crazy mpg, if I remember something like 50mpg in a 1 ton. You might be able to get on their site and find the article. But like I said it has been 3 or 4 years ago. I have always been interested in this. My basement has CNG going to it. I run the heat in my house on it. I have always wondered if there was a way to tap into this line and install a pump or what ever is needed to fill a tank from my basement. Maybe not the safest thing to do though. It might be expensive to set up, but in the long run it would pay for itself. Fuel prices are surely not going to get lower. Post it up if you come up with something. Would be interesting. Oh plus the guy in the article had a good bit more hp.

CNG isn't as efficient as propane though. It doesn't have as much energy per gallon. I do have a few customers that fill their own propane tanks from their big tanks at home. Our system uses a standard BBQ grill tank, It lasts over a month, and at less then $20 to swap out tanks, it far out weighs the cost. Most of my customers are getting a 5-6 mpg gain. Propane 100%.

I am not sure I understand the question. The way this guy was getting better mpg is the same idea as Propane. If it is injected in the diesel, then the diesel will burn more efficient, make your mpg better. I don't know a terrible lot about it, but I understand that much of it. At least I think I do lol
