The 2.0T Turbo Hurricane 4 is Insane! [Engineering Explained]

[Administrator]

Great video by Engineering Explained on the 2.0L Turbo Hurricane 4-Cylinder engine:



One of the most technically advanced four-cylinder engines ever just launched. The Hurricane 4 engine has a passive pre-chamber with turbulent jet ignition, just like what is done in Formula 1, so it can make boatloads of power without using much fuel. It uses two spark plugs per cylinder, it’s running miller-cycle, uses plasma spray cylinder liners, dual fuel injection, electric cam phasing, and a variable geometry turbo, with up to 35 PSI of boost pressure.

Oh, and it’s made by Jeep. Yep the first company making modern F1 engine tech mainstream, is Jeep. Didn’t have that on my bingo card. But, maybe I should have, considering Maserati, in the same Stellantis family as Jeep, introduced this tech to production cars with the MC20’s Nettuno engine.

I had a fascinating chat with Jeep’s engineering to learn all about this Hurricane 4 engine, and so we’re going to dive deep into understanding how it works, starting with a quick review of how turbulent jet ignition works.

What I see here is yet another engine that will be unreliable long term, hard to service at home, expensive to do 100k maintenance for, and expensive to repair in the future. Parts will be hard to get because of the unique nature of design forcing you to buy from the dealership, and pricey as well. And at the end of the day, we're talking the same or smaller power levels than Ford and GM have been offering for YEARS now.

I'll pass.

If the 5.7L V8 isn't offered in Dakota, no sale.
