As for the diesel fumigation issue, this is one of the modern snake oil witches brew topics. Almost all of the websites hawking the use of propane with diesel advertise increased power due to the "propane making the diesel burn more fully" or "acting as a catalyst to insure the full burning of diesel"------ All that is happening is more fuel is being put in an engine that already has excess air. Call it BTU plus BTU plus air equals heat.

Above is what I hear on other sites about alternative fuel, but as far as what the OK and Utah crowd is doing, You have to have the right dot approved tank with the acme--filling port to run a regular carbureted gas pickup on LPG. so far i have found out you cant just go to a forklift salvage place and get an old tank--unless its for your off road yoda,jeep, You got to cough up the money for a Manchester tank thats DOT approved, I dont know what the fines are for running illegal--I DONT need to either. |

If propane is relatively cheaper than diesel, then it would be more economical to burn it.

I have a friend that asked me if he could run up to 90% CNG as a fuel for his 240D, keeping the IP set at idle to provide ignition timing, but regulate the CNG to control the engine speed and power.
Any idea if there is a point where above a certain quantity of CNG, it will detonate or have ill effects? |

CNG/diesel has been used in commercial applications for years. There are plenty of bus companies in Australia doing it. How do you intend compressing the NG? 30 years ago in new Zealand people had small compressors connected to the back of their stove gas line that they used to fill a tank in their car over night.
It is doable.

I,ve read somewhere that diesels built to run on cng have a lower compression ratio, closer to a gas engine. So there must be a limit on how much a standard diesel will take. I must say I have no experiance with it though.

"Small compressor hooked in to stove gas line..."
LB40,
Yeah, that's the way it's "Suggested" you do it if you're running a Strictly CNG vehicle like the Honda Civic.(Honda only sells them in California and NY state.) The Electrically Powered Compressors are made by an Italian company BUT by the time they're made available to consumers in the U.S. the price has ASTRONOMICALLY climbed to $4,000. to $5,000. USD per compressor. [WHOOPS, thy're now $6,000. USD according to EWS] That's just CRAZY! MB makes an E class CNG vehicle (NO USA availability) that's popular in Europe. The CNG "Injectors" and other Equipment are made by a Brazilian company

The main problem is the cost of the refueling infrastructure. 3,600 psi is a lot of pressure. The controls would be pretty straight forward, its just the home refueling costs. Even a $1.75 per gal is better than $3.99 for diesel.
I look at it as how many miles per dollar can I get, as apposed to miles per gal. It is the money that counts, IMO. so even if blending the fuels results in an increase in the number of miles you can go per total (combined) fuel dollar, it could be worth it if the initial investment is able to be repaid in savings relatively fast. I was thinking of fogging the CNG in the intake runners or the plenum, and use a throttle valve control the quantity of gas to control the speed. |
