AUTOOL FN608 · Eight-Position Twin-Pump Fuel Injector Test Bench
Compare Eight Injectors Across Twin Independent Rails
Compare up to eight compatible standard gasoline, EFI, FSI and selected GDI injectors at 0–0.8 MPa bench pressure, with two independent pumps feeding separate rails. Select 12 V, 12–70 V or 120–180 V drive and adjust 0–40 ms pulses in 0.1 ms steps for matched spray, leakage and collected-volume checks. A standalone 550 mL, 28 kHz ultrasonic cleaner with heat up to 50°C supports cleaning before retesting.

Key Features
Eight Positions with Separate Pumps and Test Paths
Eight-Injector Comparison

Twin Independent Fuel Pumps
Two independent pumps supply separate rails for the eight-position fixture. Stop the machine and inspect it according to the manual if either circuit faults.
Standalone Heated Ultrasonic Unit
Use the standalone 550 ml, 28 kHz cleaner with temperature control to 50 °C.
Extended Injector Drive Ranges
Select 12 V, 12–70 V or 120–180 V drive to match supported standard gasoline, EFI, FSI and selected GDI injector requirements, with the correct connections and procedure.
Advanced Pulse Control
Adjust 0–40 ms PWM in 0.1 ms steps, with up to 7,500 RPM and 9,900 injections.
Closed-Loop Pressure Control
Set comparative test-fluid pressure from 0 to 0.8 MPa.
Three Cleaning Modes
Use ultrasonic cleaning, suitable top-feed reverse flush or optional-adapter no-disassembly cleaning.
Twelve Test Functions
Cover speed conditions, acceleration, variable speed, sealing, sprayability, injection shape and flow balance.
Eight-Adapter Coverage
Eight adapter groups plus a dedicated BMW adapter group support varied injector connections; verify exact fit and shipment.
GDI Injector Protection
A self-protection function supports compatible GDI test setup.
3 Years Warranty Support
Main unit: 3-year warranty. Standard accessories: 1-year warranty. Warranty Policy.
Safety & Compatibility
Confirm Injector Type, Drive, Adapter, Fluid, and Pressure
Confirm Drive And Fit
Match every injector’s part number, electrical drive, feed style, adapter and seals before energizing.
Inspect Both Pump Circuits
Do not assume the twin-pump layout makes a failed rail safe; stop and service leaks, abnormal noise or unstable pressure.
Keep Fluids Separate
Use approved cleaning fluid only in the ultrasonic unit and suitable non-corrosive test fluid in the test circuit.
Never Operate The Cleaner Dry
Fill the ultrasonic unit to the manual’s approved level before heating or sonic operation.
Control Vapor And Ignition
Ventilate the work area, wear eye protection and keep fluid away from flames, sparks and hot surfaces.
Depressurize Before Disconnecting
Stop the machine and release pressure before opening either rail, hose or injector fixture.
Use Correct Regional Power
Use the 110 or 220 V ±10%, 50/60 Hz version that matches the supply, with protective grounding.
Compare Results Under the Same Settings
Use the 0.8 MPa bench for matched comparative testing within the stated injector and pressure range; confirm high-pressure GDI performance with suitable equipment.
Test Results
Read Spray, Leakage, and Volume Across Eight Positions
Check Rail Health First
A shared difference across one rail can indicate a pump, pressure or fixture issue. Compare rail conditions before judging injectors.
Repeat A Single-Position Difference
Reseat the adapter and seal, verify the cylinder and rerun the same settings before treating it as an injector finding.
Compare Spray Shape
Compare spray pattern and atomization across matched injectors under the same settings.
Compare Relative Delivery
Use equal-time cylinder readings for relative group and before/after comparison.
Separate Leakage From Imbalance
Dripping during the specified sealing test and low delivery under a dynamic test are different findings.
Use The Retest And Boundary
Use the 0.8 MPa bench for matched comparative testing within the stated injector and pressure range; confirm high-pressure GDI performance with suitable equipment.

FAQs
Capacity, Pumps, and Fit Questions
How many injectors can FN608 test together?
Up to eight compatible injectors in eight transparent 110 ml cylinders.
What does the twin-pump design do?
Two independent pumps supply separate rails for the eight-position fixture. Stop the machine and inspect it according to the manual if either circuit faults.
Which drive ranges are available?
12 V, 12–70 V and 120–180 V for compatible injector applications.
Is the ultrasonic injector cleaner standalone?
Yes. The 550 ml unit can operate independently and heats cleaning fluid to 50 °C.
How is FN608 different from FN606?
FN608 adds eight positions and two independent pumps. FN606 has six positions and one pump; their control ranges are otherwise closely aligned.
Can it reverse-flush all injectors?
No. Reverse flushing is for suitable top-feed injectors.
Does no-disassembly cleaning require accessories?
Yes. This additional function requires special adapters.
Can the cylinders certify absolute flow?
Use them for controlled group and before/after comparison unless a calibration and approved limits are available.
Does FN608 reproduce full GDI rail conditions?
Maximum test-fluid pressure is 0.8 MPa for comparative bench testing; use suitable equipment for on-engine high-pressure GDI evaluation.
What should be checked before ordering?
Injector fit, drive range, adapters, seals, fluids, regional power, twin-pump service parts and the full current packing list.
