Aux, generator capability questions, propane injection and slack adjusters... - doug_ngl - 03-22-2007 03:08 Howdy gang, I bought a Yamaha 2800 watt generator to use on Pokey when I need some AC power, but don't want to run the big genset. Here is a link to the specs: http://www.amazon.com/Yamaha-800-Watt-Portable-Generator- YG2800IH/dp/tech-data/B0000614UI/ref=de_a_smtd/002-0603847-9582408 My hope had been that it would also run one A/C unit, but when I try, it REALLY pulls the generator down and the overload light comes on. I'm at 7800" and have had trouble with the effect of altitude on generators before (read loss of power and efficiency). Should a 2800 watt generator with a 125V/30 amp outlet run one A/C unit (basement Cruiseairs)? They run fine otherwise. Other than that, everything on Colorado is good, spring is springing and Pokey is ready for the road. I finally got my propane injection setup installed. Noticeable power difference, I'm anxious to see how it affects the fuel economy. Also, should an 81 FC35 have automatic slack adjusters? They have grease fitting on them. Any and all help is greatly appreciated.

How is it set up? Under what circumstances do you use it? What measurable difference do you experience? Does it raise EGT's? If so, how much? How hard was the install? Kerry 82 FC 35 Denver .

I tapped into the house propane tank, ran it unregulated into a propane regulator and then into a soleniod valve, from there it runs thru copper tubing and into the top of the air cleaner. I had to fiddle with orifice size and pressure, but am running it at ablut 5 PSI. Since the regulator contriols flow, the initial problem I had wa too small an orifice, I don't think you can go too big. I have a switch on the dash and flip it on at highway speeds or when accelerating, ususally not under 2000 RPM. The difference is subtle, but very apparent. It runs smoother, takes fuel and accelerates better. After talking to a chemist friend (who lost me but understood what I had done), he said it has someting to do with a shorter carbon chain in propane compared to diesel. The introduction of propane into the fuel/air mixture allows the diesel to start to burn at a lower temp/sooner and burn more completely. What I understand is that it should not adversely affect the EGT or engine as a whole in any way, at least not at the level I run it. In fact at idle, if I turn it on, the engine actually seems to miss, so there is some point at which the addition of propane will offset the air/fuel mixture in a negative way, so there does not seem to be any chance of a "runaway" situation. I still have to fiddle with the "right" amout. At highway speeds, you can reach a point where I think you not gaining anything, just using more and pumping it out the tailpipe.
