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:

The company is also working on a closed-loop water injection system as part of a "100 mpg" engine project.

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.

cool. subscibed.

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

Haha!

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!

I'll believe it when I see it.

The injector in my Metro reminded me of a controlled leak...

Everyone knows if it really works the big auto companies would have already do it. After all everything that is any good has already been invented. Might as well close down the patent office. (wink, wink)

Actually, most of them rely on third party suppliers to develop and produce these new high pressure injectors. Far as I know, though, only Nissan is looking at next generation traditional port injection with their dual injector direct-indirect set-up.

The field is small enough, I suppose, that one could break into it with a new product that delivered results without much additional cost, but

But two things ring alarm bells. The claim that "nobody else is doing it", because other companies and OEMs do perform research on nozzle tip geometry... and the claim of 60% efficiency being possible (but then again, he seems to be speaking of what is coming way down the road).

Will have to wait and see what advantages this confers when more is revealed. Direct injection may be the near future, but if there's a way to do away with the expensive high pressure fuel system, all the better.

Hi
nearest i hsve seen to different petrol furl injectors are from a company called flamethower. he sent 5 sets out free to yotatech members who have tried them. mixed reasults due to some of them asking for a larger injector. toyota engines they where tried on actually run slightly rich from factory. mach injectors to engine needs and they work really well. lower fuel consumpsion and a small lift in power. like all fuel mods need to be carefully matched and set up. rammingextra fuel into engine dose not increase power especially on slight rich engines. i have altered the spring tension on my vafm one click lean as spark plugs where black. now in process of seeing how much extra mpg it gives me so far looks to be postive good colour on plugs no loss of detectable power. engine temp still normal.

Finding the patent for their pharmaceutical injectors would probably tell us a lot.
