Wards Auto: new injector tip design said to improve fuel efficiency up to 20%

"Developer Says New Injectors Promise 20% Fuel-Economy Gains"

It's in Ward's Auto, so it must be true...

A pharmaceutical business that specializes in aerosol medicine delivery has spun off a company that's developing a better automotive fuel injector.

The crux of the claim is that the redesigned injector tip offers vastly better fuel atomization than conventional injectors, permitting faster combustion:

Quote:
“It looks like a shower head,” he says of his new injector. “The only thing we're changing is the geometry of the tip of the injector.” The orifices are the same size as in conventional injectors or even bigger, Mulye adds.

“We can get 50 times more droplets out of our injectors,” Coventry says. “The drops are smaller and burn more quickly.”
The company is also working on a closed-loop water injection system as part of a "100 mpg" engine project.

Quote:
Nostrum says it has begun a joint development project with one of the Detroit Three, but Mulye and Coventry decline to reveal the automaker’s identity.

Sounds great, but no hard data. For now I think transonic has the injector of the future and the key to the 60+% efficient engine. The other part I have beat to death here.

Agreed. Lots of talk, no evidence.

The thing that caught my attention in that one was the indirect implication that they'd be retrofittable to older engines.

At what cost?? An injector swap is doable, but the cost might outweigh the benefit.

No idea on cost. It's all just vaporware for now. (See that joke I made?!)

I wonder how they compare to the ev14 injectors I was looking at.

The main problem to overcome will be if they can perform over 100K miles without leaking, getting clogged, or blocked (egr etc build up).

A peak at where they are heading with all of it.

I wonder if there'll be a single injector replacement for my throttle body injection 3-banger!
