Subject: Generator fuel consumption Author: Ken [ Next Thread | Previous Thread | Next Message | Previous Message ] Date Posted: 02/ 19/ 07, 5:42pm Hi does anyone know what the fuel consumption on a kohler deisel generator, 84pt 35, I just purchased the coach and was amazed at how much fuel the generator used, right around 30 gallons in 12 hours does this sound right? It seems to start and run well, doesnt appear to be running rich, was thinking of pulling the injectors having them redone but If this is about normal then maybe not. That just seems like a ton of fuel for that motor. [ Next Thread | Previous Thread | Next Message | Previous Message ]

I have not checked it myself, but in my manual, I think it states 1/2 gallon per hour, but someone wrote in it beside that it is actually 3/4 gallon per hour. [ Post a Reply to This Message ]

[> Subject: Re: Generator fuel consumption Author: George Frazer [ Edit | View ] Date Posted: 02/ 23/ 07, 9:33am Hi I will look in my book when I can find it, I have a PT40 with a 12.5 KW Kohler with a 4 cyl. Perkins. I just read a short time back, mine is supposed to burn a little over 1 gal. hr., less than 2 gal. I can't remember exact amount, a friend and I were discussing it and mine was real close to his gas 6.5 Onan, a little more but almost double KW. Check exhaust, should be at most a little haze under load, if it's overfueling, you should notice grey or black exh. The darker the color, the more unburned fuel, white smoke is unfired fuel. Check air filter first. I'm getting close to putting injectors in mine and think I can get dealer discounts, if you need a set, I'll check prices. Use my regular e-mail as I rarely get to this site.

Thanks again [ Post a Reply to This Message ]

[> [> [> Subject: Re: Generator fuel consumption Author: Hi again Ken [ Edit | View ] Date Posted: 03/ 1/ 07, 10:15am I just found info in my Kohler book and it says gen. should use 1.16 gph. under rated load. If you want, I can try to scan any info out of book and e-mail to you. If you need any other info, send me your e-maqil aqnd info you would like and I'll see what I can do. Geo.
