Anyone have info on doing propane injection on diesels? Any good sites? Pros or cons?
There are plenty of sites that deal with propane for diesels.Drew said:Anyone have info on doing propane injection on diesels? Any good sites? Pros or cons?
By itself propane contains less energy per volume than gasoline. Diesel beats out both. The propane mixed with diesel improves efficency thru a more complete burn. The problem with propane is you still have to refill the tank. If you gain an increase in mpg (I doubt it would be an 8 mpg improvement) not only do you need diesel at around 1.80 per gallon but the propane as well at sometimes similar price per gallon. (Both prices dependent on region) Therefore for the slight improvement in mpg, you have to pay almost double the price in fuels instead of buying either diesel or propane. Admittedly propane doesn't burn at the same rate as diesel so you may not use up the propane as fast, but you still need the fuel, which brings up another issue. One of space. Propane tanks take up space. Sure you can install the tank under the truck if it's small, but then you use up the tank faster, requiring more frequent fill ups.SamsGurl said:well it would be a benefit in the fuel efficiency area. Just think, if you can squeze 22 mpg out of the cummins without propane, if you added it you could be in the 30's.

I was watching an old episode of Horsepower TV today, and they did a propane injection system on a Ram 2500. Had the 20 gallon frame mounted tank (had universal mounting brakets, but they mounted it to the frame) like you mentioned...didn't look hard to install, and they gained 77 horses (no mention of torque gains). Pretty slick set up. Even had an off/on switch, so you didn't have to run the propane all the time. Forget what company it was from though.RCC_SaMiaM said:BTW, if you are nit picking on space, which most of us aren't since we have trucks for a reason, they make inline frame 20 gallon tanks that would occupy a space that you would never use anyways. I would put a propane tank under my bedmounted tool box if I had one.
