Pardon the slightly off-topic post but I just came across this u-toob video on Tesla’s foray into Semi Truck transports: https://www.youtube.com/watch?v=0d3eUlvckTU&t=725s
His presentation is amateurish and off-putting but the tractors are impressive.
“A boxer engine is also notorious for vibration.”
I would respectfully differ with that. My BMW R1200RT motorcycle, which has a 1200cc boxer engine is the smoothest running bike I’ve ever owned or ridden. Of course it’s a boxer, not opposing pistons, so I don’t know how the opposed pistons would be vibration-wise.
See my previous post, aka they will license the tech to manufacturers. Dr Lemke and his funding sources got it this far, so they had capital and now Aramco runs with them as a partner. Cummings is running with it, so "large" is covered...
The question begs CNG / LPG is coming up to speed for large trucks, but depending upon fuel prices an omnivorous version of this engine would be a win-win.
Is this a picture of the African engineers?
No problemo Rockrr... Elon is an interesting cat for sure. Flat Torque curve of an electric motor for a large truck that works. if we get the 1.5x up to 5x batteries everyone claims they are on the verge of, that are solid-state ( and what is after Li-ion? Aluminum, Magnesium, Silicon, Iron Batteries or ?) he is not crazy....
“Put that into laymans terms. Will it pull a 3 bottom plow through cement?”
Now THAT language I understand!
Looks awfully tall, does it function laid out horizontally like a boxer flat four or six? That would offer some advantages in packaging as well as lowering the center of gravity.
“What size engine do you use to do that now? How much torque does it have?”
My last tractor was an 80 hp International that pulled a 3 bottom 14 inch set through the Virginia red clay.
Not sure of the torque on that tractor.
For years we used a 35 hp Ford to pull double 12’s.
Horse power is good but torque is indispensable. Enough torque and you can move mountains.
I have thought of that as well. By the looks of the Show F150 the hood maybe cut open for show purposes, and not necessarily for clearance. Yes Horizontal would and does work. Here is a Gen-Av effort ( I am not sure where the project at this moment ) that is Horizontal.
A pair of binary opposed Pistons, near as I can tell.
Per Ford for the second generation V-6:
375 hp (280 kW) @5000 rpm, 470 lb⋅ft (637 N⋅m) @2250-3500 rpm
2017 Ford F-150

“IF you are not familiar with the concept this is a Junkers ( aircraft ) type engine, i.e. two crankshafts with 2 pistons sharing a common bore and total elimination of the valve train.”
What was old is new again?
BTW, thanks for the pic.it really helps visualise the engine.
So we basically have a dual crankshaft 6 cylinder as each cylinder will be firing at both the top and bottom of each stroke?
Please correct me if I am wrong.
The internal combustion engine is old, but it ain’t going away any time soon.
>>Horse power is good but torque is indispensable.
The article says 429 lb-ft for this light truck engine. I’ve seen this same engine configuration power a 500kw generator at 0.8pf.
It’s amazing how many “conservative” FReepers are taking an instant stand against this simple, yet powerful and economical engine design.
But, honestly, comparing tractors to light trucks?
Very clever. I’ve never watched a pro b’ball game in my many years of life.
Timed direct injection.
RE 20 gallon tank.
There’s a 36 gallon tank option for the F-150.
36gal x 40mpg = 1440 miles...just lovely.
The Fairbanks-Morse locomotive engine works similarly: two crankshafts, opposed pistons, compression ignition. It uses heavy fuel, though, not gasoline. It goes back to the 1930s, IIRC.
I have a 70 hp Ford 5000 diesel that easily pulls 3-14’s in rocky southern MI.
Have you looked into the 2018 F150 Diesel?
