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.
