It's About Time Deere

You would have thought this would be a no-brainer for a company that makes farm equipment to support the corn growers that buy their equipment.

Deere investing in a compression engine fueled by ethanol

ClearFlame Engine Technologies will use ethanol and other unconventional fuel sources in compression-ignited engines. Details at Equipment World.

I sure don't like ethanol and wish it would just go away...

Honestly! If we insist on subsidizing corn let it be for cheaper corn flakes and grits.

Alcohol from corn will always be energy negative as a fuel and no amount of technology will ever make up for thermodynamic inefficiency. It's not energy dense and IMO there could only be a emissions angle to make it sound worth Deere exploring.

So hopefully they can save $$ on DPFs & DEF tanks and I wouldn't expect a lower price on farm tractors, but the system may be polished up in time to meet Tier VIII. I expect common rail injectors will be the easy part, typically not leak/drip, or require close tolerances.

Minimal visible flames if a high pressure line breaks? Check. Keeping water out of fuel, easy enough. Economical Sched 200 SS lines might get pricey to replace but nothin' Deere can't work with.

btw, who needs CRP lands when corn subidies pay better anyway? Will we make good use of our territory or just let the animals take it back from us?

Maybe they still cared about soil?

Other than energy concerns the main drawback to introducing ethanol in fuels was it's effect on metals. Adequate research and modifications were not done prior to it's introduction. Add to that the small engine industry was slow to get on board and a large segment still has not.

Protective coatings, resistant fuel components, and fuel injection is required.

As far as getting it to burn in a compression ignition engine it probably just needs lower compression, a lubricant added, along with a change in injection timing.

Using materials that resist the corrosive effect will be the challenge.

How about non petroleum Jet Fuel?

United Airlines just became the first airline in history to operate a passenger flight using 100% sustainable aviation fuel

United's SAF investment is not its only sustainable effort. United has purchased Boom's "Overture" airliner, a supersonic jet that would use 100% SAF.

Don't know if anyone has seen this but if
anyone has this type of John Deere unit
and you have to remove this screw be very
careful this guy says its very expensive!
