Any news on gas engine CUTS?

[GManBart]

Do you work in industry? There are industrial gas engines all over the place. You can't compare a vette engine to an industrial gas engine. Car engines are light duty.

Have you read the entire thread, or are you jumping into the middle here because you seem to have missed a lot.

You're also taking things out of context. I'm talking about a gasoline engine set up for use in a tractor....not a fork truck, or a genset, or anything else. There are no current gasoline gasoline tractor engines that I'm aware of (the entire topic of this discussion). Just because they make industrial gas engines doesn't mean anybody is making one that would be suitable to tractor use, much less superior to a diesel in a tractor.

Sheesh, I'm the one saying you can't compare a Corvette engine to a tractor engine....I used it to illustrate why they don't compare...they're light-duty cycle engines.

As long as our gas contains ethanol, I don't want any thing gasoline that is a seldom run or seasonal run engine. I have enough trouble keeping my lawnmower's engines from clogging up with crap from the gasoline today. I sure don't wont to have to run my tank dry on my tractor every time I park it for an extended time, and with my tractors, extended time might be anytime I stop it after I finish a task. MY LS hasn't been fired up in 3 months basically since I tilled the garden this spring. Fuel storage would be terrible also for a tractor with 20 gallon tank. You couldn't stock pile 100 gallons for a year and expect it to be fresh when you need it like you can with diesel.

Gasoline is ok for my chainsaw, weedeater and lawnmower but leave my tractor alone as it is with its diesel engine.

Fork trucks should be the testing grounds for torturing engines. Load up, pedal to the floor, let off pedal, unload repeat about 150 times a day. Average industrial forktruck is tortured far more than cars trucks and most small tractors.

Fork truck engines are RPM and power limited so that they last a long time and don't fail. For example, Toyota's current Tier IV 3.0L turbocharged 4-cylinder gasoline engine puts out a max 93hp at 2550rpm. They last a long time because they aren't making much power for their size, and they don't get turned very fast.

Still, that Toyota wouldn't necessarily be a good tractor engine. A Deere 5093E has the same 93hp Net, but it's 4.5L (and turbo-charged) at a similar 2,400rpm....50% larger to get the same net power. That's because it has to be to turn 2,400rpm for hours on end, and last for years on end.

Don't worry this thread is still twirling in the same circles from when I was in it earlier. Lol

So.. the diesel has to be a lot larger and more expensive to get the same power...err.. you're switching sides here?

Depends on the forklift and the driver...
We have several at work that are used for dumping fruit into a bulk truck, they are setup with a forward bin dumper (like this one: https://www.cascorp.com/americas/en/forwardbindumper ).
When the guys run that, its running wide open to lift 1500-2000# up to the top of the trailer and dump the bins, then it idles while it comes down, then they floor it to drive over to the row of empty bins, drop the two empties, back off the throttle to change directions, then grab another two full bins and push the pedal to the floor to begin again.
Is it at 100% load all the time? No, but it probably averages a 60-70% load on the engine for 1-5 hours at a stretch.
Its a lot more load than our BX2660 gets when mowing (because it cant move fast enough to load the engine down in grass that is less than 6" tall) or plowing snow.

Certainly going to be varying the gas engine through the power and rpm bands. A turbo diesel would be in turbo lag most of the time.

This is the key factor. Nobody makes a gasoline engine "for the use" we're talking about. That's what I'm saying over and over.





The engine in question was operated within it's normal RPM range. It wasn't revved over the limit, and there was no parts failure to allow it to go beyond redline. It was simply worked near it's maximum capability for an extended period of time. That's the exact difference I'm talking about. A light-duty cycle engine, like what gets put in cars is capable of being worked hard enough to cause major damage without exceeding it's normal limits. A heavy-duty cycle engine won't hurt itself without something unusual happening.

This talk of gas industrial and stock light engines blowing up when reved to redline is rubbish. btw lets talk about all the video's of diesel pickup truck engine failures since you brought i up. Quit trotting that drivel out. The reason why you see gas engines blow up is because you are watching a nascar engine built for max power and to last only 550 miles . What would you expect to see happen ?
The spark ignition engines in industrial and light highway applications spend less time in the shop per hour and per mile than the diesels and their emission system problems.

I never said that can't be better in some applications. I just said that a gas engine, of any kind, is inferior in a tractor...which is the topic, BTW.

"Any gas engine, in any application in any tractor is inferior"............. Reminds me of something I seen somewhere. Quote "Nothing bothers a troll more than ignoring them....well that and actual facts." Unquote

No it wouldn't, I run them every day.
They throttle up and down just as fast as the non turbo diesels IMO.

Nobody but the anti gas crowd said anything about a 200HP gas farm tractor working at 195HP for 1000hrs a season ploughing. The " there is is a place for DI gas in some small light duty applications" group is saying " there is is a place for DI gas in some small light and medium duty applications". Due to upfront higher diesel engine/emissions price, higher diesel fuel cost, diesel emissions equipment service costs in light and medium duty applications. In applications where the diesel can not 'save" money.
