FAQ

Yes, we are the original manufacturer of the diesel injector test benches and electrical testers. We design, assemble, and quality-test all our machines in our own facility. Our brand focuses on affordable, high-performance diagnostic tools, especially for developing markets. Unlike pure trading companies, we provide technical support, spare parts, and customization services directly from our factory. We also welcome OEM or private label cooperation.

A diesel injector test bench is a machine used to test and calibrate diesel fuel injectors. It is commonly used in repair shops and diesel engine testing centers.

Our test benches support major brands like Bosch, Delphi, Denso, Siemens, Caterpillar, and Cummins.

Choosing the right test bench depends on your target injector types, daily testing volume, available budget, and technical experience. If you mostly work with common rail systems, a mid-range model may be sufficient. For workshops dealing with piezo injectors, EUI/EUP systems, or needing coding functions, we recommend our advanced models. You can also consult our sales team for a free recommendation based on your needs.

We offer free online training after purchase, including detailed video tutorials, step-by-step user manuals, and live video guidance by technicians. For large orders, on-site training is also available in some regions. Our goal is to make sure you and your team can start testing confidently right from day one.

Yes, we provide OEM and ODM services for clients looking to sell under their own brand. This includes logo printing, custom color schemes, and even interface localization. Whether you are a distributor or starting your own brand, we can help you build a professional image.

No, you can use the tester independently to diagnose injector electronics. However, for a full performance check (flow, spray, leakage), a hydraulic test bench is required.

Yes, our multifunctional injector test bench supports testing both common rail and traditional mechanical injectors. You can easily switch between them by changing the appropriate fixtures and adapters.

We provide 24/7 technical support, including remote setup guidance, training videos, and troubleshooting help.

Yes, our diesel injector test bench is compatible with various injector models and connectors, making it suitable for multi-brand service centers.

Absolutely. We offer OEM and ODM for partners worldwide. You’ll get full product documentation, branding options, and technical support.

Absolutely. Our testers are designed with over-voltage, over-current, and reverse polarity protection, so there is no risk of damaging the injectors during testing.

Yes, the injector test bench is suitable for testing both new and used injectors. In fact, it is often used for diagnostics of older injectors that may be exhibiting performance issues due to wear or contamination. The bench can test injectors that have been in use for a while to ensure that they continue to meet performance standards. For new injectors, the test bench can also verify the proper functioning and confirm that they are within the required specifications before installation.

Yes. A single malfunctioning injector can cause misfires, imbalance in combustion, and even damage pistons or turbochargers over time. That’s why testing all injectors—especially when one is suspected to be faulty—is critical.

Diesel injectors can fail due to fuel contamination (water, dirt), wear and tear, excessive heat, poor maintenance, or electrical issues. Common signs of failure include hard starting, rough idle, black smoke, or loss of power. Regular injector testing helps detect these issues early.

Injector coding is a calibration code used to input injector test parameters into the ECU. Some models support generating injector codes.

Yes, the test data can be exported via USB or network in Excel or PDF format, making it easy to print, archive, or send to customers via email.

Yes, it supports coding formats.

Yes, piezo injector testing is fully supported.

Solenoid injectors respond to voltage signals and can be tested with standard pulses. Piezo injectors require high-voltage signals and very short timing. Our advanced tester has separate modes for each type to ensure accurate simulation.

Yes, it uses real ECU-like waveform signals for accurate testing.

Yes, optional modules are available for EUI/EUP testing.

Our interface supports English, Spanish, Russian, French, Chinese, Portuguese, Arabic, and more. We can also add additional languages upon request, especially for distributors in specific regions.

Yes, depending on the model, 1 to 4 injectors can be tested simultaneously.

Yes, all test parameters are editable and savable.

Common rail injectors are electronically controlled, meaning they require a more complex testing process. These injectors operate at much higher pressures and require the test bench to simulate ECU signals and monitor the injector's response to these signals. Mechanical injectors, on the other hand, are simpler in design and do not require electrical testing. The test for mechanical injectors focuses more on fuel delivery and spray patterns, while common rail injectors need to be tested for electrical pulse, pressure, and spray quality, making the process more sophisticated.

Absolutely. By ensuring that your diesel injectors are performing at their optimal level, the injector test bench helps maintain fuel efficiency and reduce harmful emissions. Faulty injectors can lead to incomplete combustion, which results in higher fuel consumption and more harmful pollutants in the exhaust. Regularly testing and maintaining your injectors ensures that they deliver fuel correctly, optimizing combustion and reducing the overall carbon footprint of the engine. This, in turn, benefits both your vehicle's performance and the environment.

Regular Cleaning: Clean the fuel system regularly and replace filters to prevent contamination. Keep the Area Clean: Ensure the test area is free of dust and debris to avoid damage to the equipment. Check Electrical Connections: Make sure all electrical connections are secure to avoid power-related issues. Periodic Calibration: Perform calibration checks periodically to ensure accurate test results. Follow Manufacturer's Instructions: Always follow the maintenance schedule provided by the manufacturer for optimal performance. Immediate Issue Resolution: Address any technical issues as soon as they arise to prevent costly repairs in the future. By following these steps, you can ensure the injector test bench remains in good condition and functions efficiently for a longer period.

Modern diesel injector test benches are designed with user-friendly interfaces, making them easy to operate even for individuals with limited technical experience. The control panels often include intuitive touchscreens or buttons with clear instructions and preset test modes. For more advanced testing, detailed instructions are provided, and the system may even offer automated calibration and diagnostic suggestions. While basic knowledge of diesel injectors and their function is helpful, most test benches come with helpful guides and support to ensure proper use.

Our tester is highly reliable for detecting electrical faults like open circuits, short circuits, and inconsistent resistance. However, it doesn't measure hydraulic performance (like flow rate or atomization), which requires a fuel test bench. It's perfect for quick electrical diagnostics.

We offer remote support and training, including system calibration, system upgrades, and a one-year comprehensive warranty. All of our test benches come with a 12-month international warranty covering non-human damages to electrical, mechanical, and systems. If you experience issues, we provide free replacement parts and technical guidance. After the warranty period, paid support and parts are also available.

We accept various payment methods, as follows: You can click here to download our payment instructions.

If any parts, accessories, or components are found to be defective due to our fault, we will promptly provide a replacement at no additional cost to you. Our goal is to ensure that your experience with our products is smooth and satisfactory, and we are committed to resolving any issues with faulty items as quickly as possible.

Depending on your specific location, we may offer shipping services that cover the costs from our local area to the port in your country, including China export fees, shipping fees, insurance, etc. However, we are not responsible for customs fees, clearance fees, storage fees, forwarding fees, and other charges in your country.
