Engines that run on gasoline and diesel

I hope it is studied more. It looks promising.
IHC had this in tractors back in the 50's. It had a gas carb/manifold/distributor on one side, and diesel pump/injectors on the
other side. Start on gas and slowly switch to diesel as it warms up.

That's an interesting concept, though it sounds different than this RCCI engine since this is always using both. The diesel is essentially a combustion enhancer.
 
Well tuners have been adding propane injection to diesels for years for higher HP and torque so the concept isn’t far fetched.

I wonder why they didn’t just improve upon that design instead of recreating the wheel.

Didn't think about that. I've always thought of that as being more similar to nitrous since its on demand and only for short bursts. But it does reinforce that dual fuel isn't a completely new concept.

EDIT:
I stand corrected. It's not like nitrous.

And that's why I don't understand why they're recreating the wheel lol. Maybe there's and engineering reason I'm missing or maybe the reason is simply "We just wanted to see if we could do it".

Now I have seen guys use propane in the same way people use nitrous (granted it doesn't work the same way but going for the same effect) where they dump massive amounts in for short bursts while drag racing, but for the most part tuners have been using it the way they described in the article.

And the results are huge. A 20 mpg increase on a 3500 duelly.

I don't think they are going to get that mixing gas but I could be wrong.

I'd love to see what would happen with propane injection on a volkswagon TDI that's already getting 50 mpg.

Apparently there are a few out there, mostly in Europe though. 70mpg, or 120mpg if you ignore the cost/use of propane. I found a quick read on cngvw.wordpress.com though his math is deceptive and ignores the cost/use of propane, focusing on only cost/mpg of the diesel. The issue with propane seems to be the lack of filling stations, similar to electric vehicles' big hurdle to mass adoption.

This also begs the question of how does gas/diesel stack up against gas/alcohol injection since that would be far simpler.

Yeah true on all points. But reading the article you linked the cost of the propane used to diesel used is still a cost savings. And the main proponents of fuel economy are because of decreases in emissions. So propane is a win on that front as well.

And while true fueling stations are few and far between for propane around here, with the small amount used I would think you could stop at a tractor supply or any number of places and refuel. And the engine doesn't stop running if you run out, it just goes back to normal.

I know my F20 has some system like that. Its sitting , waiting to begin being a project. (Ill pay you to get it running for me:)) Didn't John Deere do that as well? Like a pony motor or something?

Ford made a tractor (the fordson) that ran on both gas and kerosene. The model t could also run on other fuels.

The John Deere pony system was used on the R diesel and then the 70 and then the 730. It was a separate small gas engine that was used to crank the main diesel engine. Electric starters were not strong enough yet.
My 1906 IHC 2hp hit/miss engine has the gas/kero setup.
