Professional Diesel Injector Test Bench JZ-326B for Common Rail & Piezo Fuel 4-Pin Injectors

One Bench to Test and Code Every Modern Injector

For diesel service businesses, the difference between guesswork and certainty is the right equipment. The JZ-326B Common Rail Piezo Fuel 4-Pin Injector Test Bench is built to give workshops that certainty — combining precise injector testing with a comprehensive coding suite so every injector leaves the bay ready for installation. Whether you service a single fleet or run a high-volume remanufacturing line, the JZ-326B scales to your workload and helps you keep more jobs in-house.

What the JZ-326B Does for Your Workshop

At its core, the JZ-326B verifies injector condition and prepares it for the vehicle. Operators can test common rail injectors and test piezo fuel injectors, then rely on automatic IQA code generation to produce the correction codes a modern ECU expects. Throughout the process, the bench provides a real-time display of injection and return curves, turning raw injector behavior into clear, actionable information that supports fast, confident decisions.

Standard Functions

• Test common rail injectors — confirm fuel delivery and injector performance with confidence.
• Test piezo fuel injectors — cover the high-pressure piezoelectric injectors used across modern engines.
• IQA code generation — produce installation codes without sending work out of the shop.
• Real-time injection/return curve display — spot faults fast with live graphical feedback.

Optional Functions to Extend Your Capability

• Test the 4-pin injector and smart injector types
• Read and generate the injector QR code
• VDO-IIC coding and C2i, C3i coding
• Piezo IMA, ISA coding
• Injector correction code management
• MTU CR injector and 6-pin injector support

Why Service Businesses Choose the JZ-326B

• Fewer outsourced jobs — in-house testing and coding shorten turnaround time and protect your margin.
• Wider vehicle coverage — a single bench handles common rail, piezo, smart, 4-pin and 6-pin injectors.
• Faster, more accurate decisions — real-time curves remove the guesswork from diagnosis.
• Built for daily output — reliable performance in demanding workshop conditions.

Turning Capability into Business Results

Investing in the JZ-326B is about more than adding a machine — it is about expanding what your workshop can take on. With testing and coding under one roof, you can accept a broader mix of injector work, complete it faster, and reduce the downtime and cost that come with outsourcing. For growing diesel businesses, that added capability translates directly into higher throughput, better customer service and a stronger competitive position in the local market.

Ideal For

The JZ-326B is well suited to independent diesel repair shops, injector remanufacturers, fleet maintenance departments and distributors supplying the automotive and heavy-duty aftermarkets. It delivers the testing breadth and coding depth that modern diesel service work demands, backed by a design that is straightforward to operate and easy to integrate into an existing workflow.
