QX450 Common Rail Injector Ultrasonic Cleaner | 4.5L Compact Bath With Active Degas & Residual Heat Soak Tank

A common rail injector consists of a complex assembly of matched components: the needle and nozzle body are typically matched to within 2 µm radial clearance, and the control valve spool operates within a bore that is ground to a tolerance of ±3 µm. During engine operation, a thin film of partially polymerized fuel-often mixed with combustion soot and minute metal particles-accumulates on these precision surfaces. Laboratory analysis shows that even a 0.5 µm thick film of lacquer on the needle can increase its sliding friction by 40%, delaying the opening response by as much as 20 µs. At 3,500 rpm, this 20 µs delay translates to a 0.4° change in injection timing. Standard cleaning methods-soaking in solvent or spraying-cannot remove this bonded film. The QX450 Common Rail Injector Ultrasonic Cleaner is a 4.5‑liter benchtop ultrasonic cleaning system designed specifically for the "final clean" step, where effective degassing, precise temperature control, and residual heat soak work together to ensure that every internal surface is microscopically clean without causing surface roughening.

The QX450 incorporates a dual‑phase ultrasonic system: a 40 kHz cleaning frequency with an active degas function. When cleaning fluid is first poured into the tank, dissolved air forms microscopic bubbles that adhere to component surfaces, creating a "blanket" that dampens the cleaning energy. The QX450's degas mode runs the transducers at 50% power for 8 minutes, driving dissolved gases out of solution. This increases the cavitation intensity at the component surface by approximately 30% compared to a non‑degassed bath.

Degas Duration: 8 minutes (automatic pre‑programmed cycle)

Post‑Degas Cavitation Energy: 0.85 W/cm² (effective cleaning power)

The QX450 tank measures 260 mm x 130 mm x 130 mm-sufficient for:

Up to 4 injector bodies (with solenoids removed) in the main basket

A full set of control valve assemblies, shims, and springs in the secondary tray

Individual nozzle needles in the mesh‑covered micro‑basket

The tank is made from 316L stainless steel with a 1.5 mm wall thickness, and the exterior is powder‑coated for chemical resistance. The unit's compact footprint (340 mm x 220 mm) makes it suitable for crowded workshop benches.

The QX450 features a 1,000 W immersion heater capable of reaching 75°C. However, the cleaner is equipped with a residual heat soak function: after the cleaning cycle completes, the heater remains active in a low‑power "hold" mode for up to 15 minutes, maintaining the bath at set temperature. This ensures that the cleaned components remain warm, allowing any remaining cleaning fluid or rinse solution to evaporate from the internal passages, preventing water spots or solvent residues from re‑depositing.

Temperature Range: Ambient to 75°C (±1.5°C)

Hold Mode: 75°C for up to 15 minutes post‑cycle

The QX450 includes a three‑piece basket system, allowing simultaneous cleaning of different injector components without mixing:

Main Basket: 200 x 100 x 80 mm, 1.5 mm mesh, for injector bodies and large components.

Secondary Tray: 180 x 80 x 40 mm, 2.0 mm mesh, for springs, washers, and small parts.

Micro‑Basket: 100 x 50 x 30 mm, 0.8 mm mesh, for nozzle needles and metering orifices.

The baskets are suspended 15 mm above the tank bottom, protecting components from the high‑intensity cavitation field near the transducers.

Q1: What is the difference between the QX450 and the QX700?
A: The QX700 is a 7‑liter unit with sweep‑frequency technology (38–42 kHz) for larger workshops handling multiple injector sets. The QX450 is a compact 4.5‑liter unit with fixed 40 kHz and an active degas mode-ideal for smaller workshops or as a dedicated "final clean" station for disassembled components.

Q2: The degas mode runs for 8 minutes-is it always needed?
A: For fresh cleaning fluid, degassing is highly recommended. For fluid that has been standing for a few hours, some gases will have re‑dissolved, so degassing is still beneficial. For fluid used earlier the same day, degassing can be skipped. The QX450 allows you to toggle degas on/off per cycle.

Q3: Can I clean the entire injector without disassembling it?
A: No. The QX450 is designed for disassembled components only. Cleaning an assembled injector will not remove contaminants from internal crevices, and could damage the solenoid or piezo actuator. Always disassemble the injector before cleaning.

Q4: How do I know if the cavitation is strong enough?
A: You can perform the "aluminum foil test": place a 50 x 50 mm piece of standard kitchen foil in the bath with the cleaner running. After 2 minutes, the foil should show uniform perforation (small holes) across its surface. If the perforations are concentrated in one area, the tank may have standing wave issues; the QX450's tank geometry minimizes this.

Q5: I work mainly on piezo injectors-are there any special precautions?
A: Remove the piezo stack before cleaning. The stack is composed of ceramic layers that can be cracked by cavitation forces. The QX450's power level (150 W) is lower than industrial units, but we still recommend keeping the injector body immersed with the stack removed.

Q6: What cleaning fluids are compatible?
A: The 316L tank is compatible with water‑based alkaline detergents, neutral pH cleaners, and hydrocarbon solvents (e.g., kerosene, mineral spirits). It is not compatible with halogenated solvents (trichloroethylene, perchloroethylene) or strong acids, which can attack the tank and transducer bonding.
