Trouble Sourcing Specialty Fuel Injectors
Trouble Sourcing Specialty Fuel Injectors
(OP)
Howdy
I am working on an gasoline engine development project, and am having a bit of trouble sourcing appropriate fuel injectors. This is a port injection configuration, and I cannot accomodate multiple injectors/port.
The main issue is that I have very tight space constraints, with relatively large flow rate requirement and spray pattern. The injector must flow 13g/sec (43psi), split stream nozzle pattern, and (the problem) the injector must be no taller than 2.20" from the bottom o-ring to the top of the fuel rail, as well as being a low impedance injector (1.8-2.5ohms).
I have made contact with siemens, bosch, magnetti marelli, delphi, without much success..
If anyone has any leads on a specialty fuel injector manufacturer, or has an 'in' at one of the major players, I would much appreciate it.

13 g/sec is well beyond most normal liquid port injector specifications for static flow at 3 bar (approx 43 psi.) 2-4 g/sec is fairly typical of an OEM type injector. Some of the "racing" application injectors run 6-8 g/sec. One possibility would be applying a gaseous fuels injector (designed for Propane, Natural Gas, Hydrogen, etc . . .) but metering liquid.
I previously worked for a company that manufactured such an injector (Quantum Technologies.) They use a company called RC Engineering as a representative for small volume applications such as motorsports, hobbyists, university vehicle teams (SAE, Futuretruck, etc . . ..), and other non-OEM customers.

RC Engineering also handles many other types of injectors, and should be able to help you find a suitable flow spec port injector, if one exists.

Ataloss: Spoke to Bosch Motorsports today-Definitely much more helpful than the 'standard' bosch line. Their standard EV6 injector has a static flow rate of around 11g/sec-which supposedly will acheive my required flow rate at about 4.5-5bar base pressure.
NCShane:I dont have my notes handy, but I believe I spoke with a gentleman in marketing/sales. He was going to talk to his R&D dept about the potential of adapting a current model injector for this high flow rate-which sounds like you are probably the man I need to speak to..I will ring you guys tomorrow..is there an ext # to reach you directly?
Tstaples: I have conducted business with RC engineering in the past, and they infact, were the first call that I made. They do supply injectors with very high flow rates, but none are of a compact nature.

If not give them a ring anyway theyve always been very helpfull to me and i believe they will do some custom work for the right bank account!

Magneti Marelli has a Motorsport department which is extremely flexible and experienced in term of custom applications. They have or they can arrange for sure what you are looking for.
You can visit the homepage www.magnetimarelli.com and then enter motorsport section. I think to remember that there is also a downloadable catalog.
Look for IWP-R which is the racing version of the Pico injector.
Marelli has a Motorsport office in Detroit:
