I would think lower emissions, but more importantly (maybe?) lower particulates.

Yeah I was going to mention Diesel-gas hybrid as an option instead of straight gas (until Locomotive beat me to it with proper info!)
They use that setup on some trucks over here (probably over there too) apparently the Diesel-Gas hybrid gets more power and a cleaner burn of the fuel. I've only heard about it and seen a couple of places advertising the systems, but haven't looked into it so I'm not sure on the upfront cost vs payoff period vs cost savings on fuel.

Just a diesel truck injecting propane for better fuel economy and a slight bump in power.

I use nitrous injection in my diesel and we have experimented with propane and natural gas.
(cummins diesel drag truck) Propane didnt give a big enough power boost,natural gas made the EGT's to hot NOS gave a good bump in power and a cooler burn then Natural gas.

Just a burnout but this is my truck that I use NOS injection on

I just did a bit of a google about the type of gas (LPG, not gasoline) that they sell at our local servos. Apparently its a mix of propane and butane.

Is this a street truck too? Mr. Obama needs to apply some of his EPA emissions restrictions to those who chip up their diesels on the street and leave those black clouds for others to drive through and breathe.

Trying this again? Makes sense since LNG is cheaper now. Just read about the BN trying this experiment with a pair of SD40-2's before they merged with the ATSF. (sad day)

BN #7149 and #7890
