NTS200 Common Rail Injector Test Bench – Full-Service Diesel Diagnostic System

For high-volume diesel service operations and remanufacturing facilities, the NTS200 Common Rail Injector Test Bench delivers an advanced diagnostic platform that moves beyond conventional flow measurement. This fully automated system has been engineered to handle the complete range of electromagnetic and piezoelectric injectors produced by Bosch, Delphi, Denso, and Siemens, bridging mechanical calibration with digital ECU integration. Workshops can now execute precision test sequences while simultaneously generating manufacturer-specific correction codes, a capability that directly addresses the traceability demands of modern common rail systems. The bench integrates high-resolution flow sensing with electrical diagnostics and remote connectivity, offering a unified solution for injector reconditioning that meets OE-level tolerances.

From Bosch CRI pieces to Delphi DFI, Denso G3/G4, and Siemens/VDO units, the NTS200 performs full-automatic detection on every common rail injector variant currently in service. All piezoelectric injector types, including those fitted to Euro 6 heavy-duty engines, are accommodated without requiring manual mode switching. The industrial computer executes complete test routines-encompassing leak checks, pilot injection (VE), idle (LL), emission (EM), and full-load (VL) fuel quantity measurements-under rail pressures reaching 2,600 bar. Flow measurement accuracy is maintained at 0.1 ml per 1,000 strokes, with injection and return oil curves presented in real time on the integrated LCD interface. Beyond hydraulic testing, the system incorporates solenoid valve inductance and capacitance detection, enabling technicians to identify coil degradation or insulation breakdown that would otherwise remain hidden until after reinstallation.

The NTS200 distinguishes itself through its onboard coding engine, which transforms test results into actionable ECU data. For BOSCH injectors, the bench automatically generates QR codes that encode individual fuel correction values. DENSO units receive their own online-generated QR codes, while DELPHI injectors are provided with C21 and C31 codes, and SIEMENS (VDO) pieces output IIC codes directly from the test cycle. This digital output eliminates the need for separate coding tools or manual data entry, reducing human error and ensuring that every remanufactured or new injector leaves the bench with the precise alphanumeric string required for engine control unit adaptation. The internal database stores OEM specifications for thousands of injector models, automatically comparing measured performance against factory thresholds and delivering clear pass/fail determinations without operator interpretation.

Precision flow measurement alone does not capture the full condition of a high-mileage injector. The NTS200 measures both the injector response time (BIP - Beginning of Injection) and the dynamic stroke (AHE) of the needle assembly, detecting mechanical lag caused by spring fatigue, sticky plungers, or worn hydraulic components. These dynamic parameters are critical for diagnosing injectors that pass static flow tests but still produce poor combustion behavior when installed. To keep the system current with evolving diesel technology, the bench supports online remote assistance and system upgrades. Technicians can receive real-time diagnostic support from the manufacturer during complex fault-finding sessions, and software updates are delivered over the internet to ensure the latest injector definitions and test profiles are always available without requiring on-site service visits.

Q1: Are adapters for heavy-duty injectors (e.g., Denso 27mm/32mm) included in the base package?
A: The NTS200 ships with a comprehensive adapter kit covering the most common automotive and light-commercial injector sizes. For larger heavy-duty pieces, we recommend confirming your specific dimensional requirements with our support team at the time of order so that any additional adapters can be bundled with the shipment, ensuring the unit is ready for production immediately upon delivery.

Q2: How frequently should calibration checks be performed on the flow measurement system?
A: We advise scheduling a calibration verification every 12 months or after approximately 5,000 test cycles, whichever comes first. The system includes an onboard self-diagnostic routine that alerts the operator when reference values drift beyond acceptable limits, allowing workshops to schedule maintenance proactively and avoid measurement inaccuracies during critical remanufacturing jobs.

Q3: Will the remote assistance feature allow your engineers to control the machine from your headquarters?
A: Yes, with explicit permission from the workshop operator, our support engineers can initiate a secure remote session to view live test data and, if necessary, adjust system parameters during troubleshooting. This feature has significantly reduced mean-time-to-resolution for complex diagnostic issues, as problems can often be identified and resolved within the same working day without dispatching a field technician.

Q4: Can the NTS200 differentiate between solenoid and piezoelectric injector types automatically?
A: The operator selects the injector model from the onboard database, and the system then automatically applies the correct test parameters and electrical drive signals for either solenoid or piezoelectric technology. This prevents accidental damage to piezo crystals from incorrect voltage application and streamlines the test setup process.

Q5: What ongoing costs should we budget for regarding software subscriptions or data updates?
A: The core test software and injector database are included with the initial purchase. Standard bug-fix updates and new injector profile additions are provided free of charge during the first year. After this period, annual maintenance agreements are available at competitive rates, covering continuous database expansion and priority technical support access.
