A guide of common rail test bench select and avoid pitfalls

03 Jul 2025

In the field of diesel engine maintenance, the common rail injector is called the "precision valve in the heart", and its status directly determines the power, fuel consumption and emissions. An efficient, accurate and reliable injector test bench is the core guarantee of the technical strength and efficiency of the repair shop. Today, we will take you to deeply analyze the industry benchmark - CR318-PRO high-pressure common rail electronic control injector test bench, and provide you with a key guide to purchase and use.

The injector test bench is not a simple upgrade of traditional equipment, but a comprehensive innovation from modular design, pipeline/line optimization, industrial aesthetics to intelligent control system, achieving a qualitative leap. Its core advantages are:

1. Extraordinary compatibility:

Full brand coverage: Easily handle thousands of models of electronic common rail injectors of mainstream brands such as BOSCH, DENSO, DELPHI, CATERPILLAR, CUMMINS, SIEMENS, etc., and piezoelectric injectors are no problem. Strong data support: Built-in 8000+ injector standard database, test with basis.

2. Fully automatic intelligent test system:

One-click high efficiency: The upgraded "one-click flushing" function greatly simplifies the process and improves efficiency. Full range of test items: Accurately complete all-round tests such as high-pressure sealing, full-load/idle/discharge point injection volume, oil return volume, pre-injection volume and oil return volume, opening pressure/pulse width/response time, solenoid valve resistance/inductance value, armature lift, etc. Correction code generation: Automatically generate mainstream oil volume correction codes such as QR, IQA, IMA, ISA, c2i, c3i, (VD0)ICC, etc.

3. Accurate data and efficient management:

High-precision measurement: Adopt high-precision gear flowmeter to ensure reliable oil volume data. Data comparison on the same screen: Display 6 sets of test data at the same time, and the comparison and analysis are clear at a glance. Support custom test process and automatically generate professional test reports.

Faced with a wide range of test benches on the market, how to avoid pitfalls? The CR318-PRO gives the answer with strength:

Avoidance point 1: Incomplete test coverage, equipment is quickly eliminated?

CR318-PRO solution: Confirm that it supports all mainstream brands (especially Bosch, Denso, Delphi, Cummins, etc.) and thousands of models within your business scope, and has a built-in 3000+ database. Piezoelectric injector support is a must.

Avoidance point 2: Single test item, unable to accurately locate the fault?

CR318-PRO solution: The verification equipment must be able to complete all-round tests such as high-pressure sealing, full load/idle/emission point/pre-injection oil volume, return oil volume, opening pressure/pulse width/response time, resistance/inductance, lift, etc. Its intelligent fault location judgment function is an efficiency artifact.

Avoidance point 3: Inaccurate data, repeated testing wastes time?

CR318-PRO solution: The core lies in the measurement system. Confirm the use of high-precision gear flowmeters and Bosch original-level pressure control components (sensors, common rail pipes, PCV valves). Accurate control of oil temperature also directly affects the results.

Avoidance point 4: cumbersome operation and low efficiency?

CR318-PRO solution: One-button flushing, custom test process, 6 sets of data on the same screen, automatic report generation, and humanized rotating touch screen are the keys to improving efficiency. Ergonomic design reduces operating fatigue.

Avoidance point 5: The equipment is bulky and difficult to use, and the scalability is poor?

CR318-PRO solution: Modular design facilitates maintenance and upgrades. WIFI support and remote service/upgrade capabilities ensure that the equipment remains advanced for a long time. Special customized fixtures and wiring harnesses ensure stable and efficient connections.

Avoidance point 6: Poor durability and high maintenance costs?

CR318-PRO solution: Key pipelines must be industrial pressure-resistant 304 stainless steel seamless pipes, and the fuel tank is 304 stainless steel. Strengthen the tempered glass protective door to ensure safety and convenient observation. The overall structural design reflects durability.

In 2025, when technology is rapidly iterating, choosing a high-pressure common rail test bench like CR318-PRO, which integrates top compatibility, fully automatic intelligent testing, precise data management, top hardware configuration and excellent human-machine interaction, is not just buying equipment, but also implanting the core competitiveness of efficiency, precision and reliability for the maintenance plant.
