Any news on gas engine CUTS?

[kenmac]

go back to the days when GM built the 366 truck engine.. It was a heavy duty tough engine.. A tractor could be built with a gasoline engine.. I would buy 1 over a new diesel due to all the EPA mandates

You're making it up. Engines don't fail for heat buildup when run at designed power outputs.
What exactly is "An engine very happy with short bursts of power "?

When they fail thats the underlying reason. ... A gas car engine.
Try running one uphill wide open for a hundred miles.

You can run a gas engine WOT all day long as long as it's within the designed RPM range. For your example...a car engine. designed for sustained 1,500 to 3,000 rpm operation.
You can keep them pinned all day long. You are purposely trying to confuse redline RPM. That's not the intended normal operating RPM. Do you really think 6k rpm's is the intended run speed?
Please....

And now this....from the poster of arrogant condescending posts on the previous pages.
I guess now that you have validated it from somewhere other than some of us here, it must be worthy of conversing now.:thumbdown:

And I notice you didn't copy the second half that showed they discontinued development for specific reasons. I'm guessing there was a reason why I was messaged and not you.

Who knows. Its definitely a light duty use - just like a forklift. Typically using a low fraction of the HP.
,,,,You can keep a gas engine pinned for fewer days than a diesel.

Automotive engines used in large boats run at higher rpm and much higher power outputs than they would if detuned for tractor use. From what I've read they last about 1000 hours between overhauls. It would be much longer at tractor power levels.

Overheating? My Chevy 350 pickup has run wide open for a half hour or longer pulling a mountain pass with a trailer on a 100 deg day without overheating.

Are those engines using ambient water for cooling?

Concerning the hillclimb: A good cooling system will do that. That is an average temperature tho. What specific engine parts saw determined how much they suffered. Degradation caused is cumulative. If your 350 is a diesel it suffered less than if gas.

Sounds fine. But that was only for 1/2 hour. Scut and cut tractors need to run for hour after hour after hour.

Just as importantly . . your radiator didn't overheat but what was youe engine temperature? Wide open . . . Wow . . . Good way to cook your oil or tranny fluid.

So you agree that starting and stopping loaded is harder on an engine than a fixed continuous load? But you still say a lift is a light duty job when it is a constantly starting and stopping application with a heavy weight machine usually over 11,000 LBS of machine or more and then weight is added to it continuously then repeated over and over again with the RPM going up/down and everyplace in between! Actually it sounds a lot like doing a day of loader work with a tractor to me the difference being that we wont all hammer the **** out of our tractor but those warehouse lift drivers are basically nuts and have no respect for those machines its abuse no doubt about it and its a heavy use application no matter how you slice it!

My guess is if you took an engine from a lift that has spent its life in a big warehouse and installed it in a scut it would think it was on vacation!!:laughing:

I never said a fork truck was a light duty cycle. I said it wasn't as heavy duty a cycle as a tractor.

Further, fork trucks don't have anything that puts shock to the engine the way PTO implements can, so they have to be built to withstand that.

If a fork truck engine could survive in a tractor they would have switched tractors over to using engines that small and light (for their power output) years ago.

Automotive gas engine were used in ag equipment (combines come to mind) years ago by major manufacturers like JD, MF, AC, Oliver, a few that I had or remember from back in the day,,, Chrysler 255 slant 6, GM 292 6, GM 350 V8, all had governors, and everyone I had would run 24/7 without issues and although some were gas guzzlers they were very cheap to overhaul using most parts from the auto store.
