Anyone here tried a CNG (compressed natural gas) fumigation kit on their diesel? I guess it's similar to LP, but more potent.

Sounds too good to be true, but there is a guy here that 50mpg out his durataxi:

CNG is only .63/gallon around these parts. Might make sense if it worked.

 

I wasn't going to post the source of my inquiry at risk of advertising for the company, but here it goes anyway. Has anyone tried a Deluca Fuel Products kit?

Just wondering if it works?

 

It will work, except the mileage they claim does not include the CNG used in figuring into the fuel mileage. Just for the record CNG has less BTU's than LP. I fumigate with LP and get a couple more miles to the gallon after you include the LP used. They also are retarding the timing to get better economy, this is against common practice but the fuel ignites faster than just plain diesel fuel. Also I read paying upwards of $5000.00 for a conversion, thats insane.

 

I think Deluca is charging less than $1k for the parts, plus a tank (another $1k I believe) for a fumigation kit.

A conversion to CNG on a diesel is a whole 'nuther story and cost prohibitive, because you'd need spark plugs.

I guess you could go this route:

No spark plugs needed with a fumigation. If your needing spark plugs your going to need to lower the compresssion. Cummins has a CNG engine and thats what you see in the Ebay ad.

 

Yeah, I think we're saying the same thing.
