Tesla Files New Patent For Gas Engine With ‘Plasma Igniter’

Tesla engine april fools

We’re not quite sure what to make of this, but it appears that Tesla – famous for making electric vehicles cool and sexy – has been working on some sort of gas-powered range extender. We know this from a patent filing we found as part of our regular skimming of EV patents (see the first two entries in the series here and here). As we say every time when we write about patents, just because a company files an application for a particular technology doesn’t mean that it will end up in a production vehicle, but this one is undoubtedly interesting.

The language of patent applications is never really easy to understand, and this one is no different. Here’s one of pertinent segments:

A method of igniting a fuel within a combustion chamber defined by a cylinder block of an internal combustion engine includes injecting a first portion of a fuel into the combustion chamber, and energizing a first plasma igniter. The first plasma igniter is configured for generating a first plurality of free radicals, extends through a cylinder head mated to the cylinder block, and protrudes into an intake port defined by the cylinder head that is disposable in fluid communication with the combustion chamber. After injecting the first portion, the method includes activating a second igniter configured for initiating a flame within the combustion chamber to thereby ignite the fuel. The second igniter extends through the cylinder head and protrudes into the combustion chamber.

How this is dramatically different from the internal combustion engines we already have is not entirely clear, but if the U.S. Patent Office thinks it’s worth approving, then there must be something there. This patent, number 401APF, is buried deep in a group of patent applications that are otherwise uninteresting. This group mostly covers minor battery technology improvements, things that we would expect from an EV-centric company like Tesla. What’s strange is that this patent was directly authored by CEO Elon Musk, the man who came up with the hyperloop and is boring a tunnel between his office and LAX.

Reached for comment, a Tesla spokesperson gave a brief statement to InsideEVs: “Our CEO hasn’t been himself lately, especially after spending so much time at Trump Tower. We can only assume that Musk has heard something in those meetings that he has not yet told the rest of us, and that’s why he has come up with this unusual idea, to add a gasoline range extender to our electric vehicles.” We’d be foolish to not investigate further.

Wow! Elon must really be a fool πŸ˜‰

Keep in mind it is April Fools’ Day πŸ™‚

Dave86

Thanks, I needed that!!!

I was really baffled why a small auto maker like Tesla would waste valuable R&D money developing an ICE.

james

Perhaps the patent number 401APF or 4/01 April Fools is a nice give away too.

SolarStorm

Sounds about right. But given the cost of filing patents, is it really worth wasting money on this?

alohart

Many Swedish and Norwegian newspapers have decided not to publish April Fool’s Day stories because so many people now believe fake news. Sad, but true…

Pushmi-Pullyu

How sad. Just because people sometimes fail an intelligence test, doesn’t mean we should stop giving intelligence tests!

Samwise

The US election clearly shows sometimes you can fool enough of the people, enough of the time.
Well at least to get yourself elected president.

Although Honest Abe got daily reports through Digital Communication systems, the internet had to wait to be invented by Al Gore.

(1/2 of that statement is true.)

Dan

That’s one way to spin the fact that nobody reads Swedish and Norwegian newspapers anymore. ?

Toby

Interesting, an ICE with a Tesla logo. He really must have spent too much time in the Tower… πŸ˜‰

DangerHV

I am so gullible!.. Grrr!

Anti-Lord Kelvin

I was even been told that this engine will be in the first Tesla Mars Rover which should land at Mars in 1 APRIL of next year!

MikeM

I heard they’re still working on a revised oxygen sensor for that.

Terawatt

May this one be for Model Trump?

hector

XDDDD

Mister G

APRIL FOOL???

David Murray

While probably a joke… I do wish some manufacturer would invest in an engine specifically designed as a range extender, possibly eliminating the crankshaft and using the pistons to move magnets through coils.

Better yet, how about room temperature hydrocarbon fuel stock fuel-cell? If that fuel is gasoline and efficiency about 50%, that would be far better than burning it. Sadly, I doubt many will research into such things, or make investments even if such thing shows promise.

Nick

That sounds like Solid oxide fuel cell research.

I think we’ve got some of that.

Walt

Musk I guess works for Hyundai now?

Evz3

Model Trump coming up

Totally plausible, that’s the Trump Administration Compromise.

Looks promising!

Bill Howland

Some other car company came up with a multi-note horn that you can signal with your change in personality moods.

How that differed from the 70 year old multi horn junk that J.C. Whitney used to always sell is not clear either.

Maybe this 4 cyl engine will power Musk’s Hyperloop compressor? Sucks coal out of the mine as it whizzes by, probably.

Happy April Thirst

April fools!

instant tq

hey this one really got me off guard

Pushmi-Pullyu

Thank goodness someone finally came up with a way to burn off all those free radicals! (They were marching and waving signs and chanting and the whole bit!)

* * * * *

M: Too many free radicals. That’s your problem.

JAMES BOND: “Free radicals,” sir?

M: Yes. They’re toxins that destroy the body and the brain, caused by eating too much red meat and white bread and too many dry martinis!

JAMES BOND: Then I shall cut out the white bread, sir.

Carcus

Funny,.. I thought founding Neuralink (when you’ve already got 3 futuristic companies running in the red) sounded more “Foolish” than a range extender.

Anon

Elon’s feelin’ pretty good after his last SpaceX Launch / Landing.

Happy April Fools Day, everyone. πŸ™‚

“but if the U.S. Patent Office thinks it’s worth approving, then there must be something there.”

Nope. Not by a long shot. USPO have obligatory monthly quotas for accepted applications, and no such thing for rejecting applications.

USPO can also reject only select claims on the patent and then accept rest, and applicant can reapply as many times as necessary in case of rejections.

Patenting thousands old business practice (by slapping “on a computer”), is not beyound USPO.

Law mandate that granted patents are valid… but to be sure patent would have to be litigated…

Pushmi-Pullyu

1. It’s the USPTO, the United States Patent and Trade Office, not the USPO.

2. The patent office in general certainly does not have any “quota”, whether or not individual patent examiners do. In fact, not so long ago the patent office changed the rules to make it harder to get a patent, because there are now far, far too many companies using patents as a business strategy of one type or another, which has gotten rather far away from the original purpose of patents: “To promote the progress of science and useful arts, by securing for limited times to authors and inventors the exclusive right to their respective writings and discoveries.”

3. The quote you cited was a joke.

Pushmi-Pullyu

Ack! An error in my correction! 😯

Make that: USPTO = the United States Patent and Trademark Office

Tesla should rather develop a miniature reverse heat pump that could turn thermal energy from the surrounding air into electricity. Would make a great range extender. Could this physically work?

fasterthanonecanimagine

Theoretically, this is possible (Sterling motor + heat pump), but could efficiency be sufficient?

Pushmi-Pullyu

Any heat pump, including a Stirling engine, requires heat to flow “downhill” from a hotter place to a colder place to perform useful work. So the idea of getting useful energy from the surrounding air is problematic. That would require some of the surrounding air to be significantly cooler than the rest. Trying to use ambient heat to perform useful work would be attempting to build a perpetual motion machine.

As far as efficiency goes, Stirling engines are very efficient indeed. The problem is they produce very little power, which is why there have been almost no attempts to use one to propel an automobile, even as a concept car.

Bill Howland

Nope – Violates the Second Law of Thermodynamics.

paul smith

It must be running on laughing gas.

Nice April Fool’s piece (-:

Martin T.

Yes a dead give away, say ICE have had spark plugs for a while ha ha …

Null

Wow!
3-d chess move!

He now has patent on tech for most effective/ efficient ingnition tech! Smoky Yanuck would love this, coupled w/ curent ceramic cylinder coatings would really improve power, efficiency, and emissions.
