Diesel alternative fuels

[spuck77]

I know that recently the fuel prices have come down a little, but I am still looking for fuel options. I have looked into bio diesel and veggie oil and am still working on getting set up to make my own. I have recently been looking at adding or building a natural gas injection system. I have heard the same things with this as with all other mods like, it is cheaper to run, gets better mileage, and you've heard the rest. Has anyone tried this or know where to start?

Have not tried it but if you are looking for somewhere to start you should scroll down to the diesel section and look at the page devoted to alternative diesel fuels. Further on down and you will come to the Alternative Fuels page. Happy reading.

All the transit buses in Los Angeles have been converted from Diesel to natural gas, so it can be done. They have the fuel tanks located on the roof, because CH4 takes up much more volume than fuel oil per BTU of heat energy. I think they are LNG, not CNG, something the average motorist would have no source of supply.

Why did you make the statement "gets better mileage"? Its just the opposite, a big hit in range if you dont have room for a lot of extra tanks. A CNG Crown Victoria has about half the range and half the trunk space of a gasoline-powered one.

If they are using methane (CH4), then LNG is highly unlikely.

Natural gas is methane, in compressed (CNG) or liquid (LNG) form its still CH4. I was not talking about LPG (Butane and/or Propane).

LNG is mostly used during transportation. In any case, I searched, and they appear to use CNG and HCNG. Green Car Congress: City Engines In 30% HCNG Transit Bus Project
