Injector swap for better atomization, Ranger - Fuel Economy, Hypermiling, EcoModding News and Forum

beatr911 · 01-22-2010, 01:45 PM

I've done a search and cannot find the thread on swapping injectors to multiple hole types for finer fuel atomization. Can anyone find it or recommend some information on how to swap to modern injectors that have finer spray droplets?

I'd like to swap out my Ford Ranger single hole pintle style for something better.

Thanks in advance!

BUMP!

Wanted to bump this thread because I am wanting to do the same with my 1997 Ranger. I have looked and found some info, but e-mailed the poster in that particular thread and haven't heard back. Maybe not a member anymore? I drive about 120mi. a day for work and want to get as much MPG as I resonably can. This sounds like a viable option, but not being a mechanic (just an electrician) I am at a loss. Any help would be appreciated.

Thanks.

I'm planning to do this to my Jeep at some point as well. I don't know about the Rangers, but I know for my Jeep the Ford Motorsports 24lb injectors (4 hole, rebranded Bosch +4) work fine. The 19lb ones may be good for a Ranger.

That link doesn't seem to discuss the multi-hole variant.

Replacing injectors is as easy as bleeding the fuel line removing the clips from the fuel rail to the the injectors and wiggling the injectors out. That is the basics of how it is performed. I'm not sure on spray and what ones to go for but I have read that some of the benefits can be achieved with an adjustable FPR (fuel pressure regulator). By upping the pressure fuel sprays out quicker and finer to achieve the commanded AFR. This will reduce the duty cycle of the injectors having them fire for a shorter time allowing more time for the fuel to be in the cylinder and help if you are maxing the injectors out (no one should be doing that regularly here).

Good idea, also therangerstation has some good folks as well. I'll try it, as finer droplet size is good for the power mongers as well, less chance of getting flamed ya know.
