CR819S Common Rail Test Bench: The Ultimate High Pressure Common Rail Pump Tester & Diesel Fuel Injector Testing Machine

In the rapidly evolving world of diesel engine diagnostics, precision and versatility are non-negotiable. Whether you are running a diesel repair workshop or a fuel injection service center, having reliable testing equipment is the backbone of your business. Today, we are taking an in-depth look at the CR819S Common Rail Test Bench, a state-of-the-art high pressure common rail pump tester and diesel fuel injector testing machine designed to handle the most demanding diagnostic tasks with unparalleled accuracy.

Unlocking Precision with Advanced Injector Testing

When it comes to injector calibration, the CR819S acts as a highly sensitive diesel fuel injector testing machine. The operating software provides a highly intuitive interface that allows technicians to monitor every critical parameter in real-time.

As seen in the system's interface, the machine conducts a comprehensive suite of test steps, including WARM, LEAK, Back, Max, TL (Full Load), LL (Idle), and VE (Pre-injection). It precisely measures injection volume (Q_Inj) and return volume (Q_Ret) in mm³/H. Furthermore, the CR819S is equipped with advanced electrical testing capabilities, including BIP (Beginning of Injection Period) measurement in μS and inductance testing (μH), ensuring that even the most complex piezo and electromagnetic injectors are calibrated to OEM standards.

Comprehensive Pump Testing Diagnostics

Beyond injectors, the CR819S shines as a heavy-duty high pressure common rail pump tester. Modern diesel pumps require meticulous testing of flow rates and pressure stability.

The dedicated pump testing module allows operators to execute steps such as Visual Check, Max Power, No Flow, Efficiency, Start, IMV 1, and IMV 2. The system accurately tracks RPM (/min), flow rates (L/H) for both Q_Out and Q_Ret, and pressure metrics up to high MPa/Bar levels. Integrated temperature controls for fuel and drives ensure that the pump is tested under real-world engine conditions, preventing false diagnoses and ensuring optimal pump efficiency.

Core Functions & Configuration Options

To meet the diverse needs of diesel workshops, the CR819S Common Rail Test Bench offers a flexible configuration. Below is a breakdown of its standard and optional features.
