Common rail injector test bench core equipment to promote diesel engine technology

20 Jan 2025

With the rapid development of modern diesel engine technology, the performance of common rail injectors, as key components, directly affects the engine's power, fuel economy and emission levels. In this context, the common rail injector test bench, as an important equipment for injector detection and calibration, has become an indispensable tool in the field of diesel engine maintenance and development. Today, let's talk about the functions, advantages and importance of the common rail injector test bench in the industry.

First of all, what is a common rail injector test bench? A diesel test bench is a device specifically used to test and calibrate high-pressure common rail injectors for diesel engines. It can simulate the real operating environment of the engine and test the injector's injection pressure, injection volume, injection time, spray pattern and other parameters to ensure that the injector's performance meets the standard requirements.

The test bench usually consists of a high-pressure oil pump, a measurement system, an electronic control system and an operating interface, and can be adapted to common rail injectors of different brands and models (such as Bosch, Delphi, Denso, etc.).

What are the advantages of the common rail injector test bench?

1. Improve maintenance efficiency. Through precise detection, quickly find the problem points of the injector, reduce maintenance time and improve work efficiency.

2. Ensure engine performance. The calibrated injector can accurately control the injection amount and injection time to ensure engine power output and fuel economy.

3. Reduce emission pollution. Accurate calibration of the injector helps to reduce diesel engine emissions and meet modern environmental standards.

4. Easy to operate. Modern test benches are equipped with intelligent operation interfaces and automated detection processes, so even beginners can get started quickly.

5. Versatility. One device can detect multiple injector parameters, which is suitable for multiple fields such as automobile maintenance, engine manufacturing, and research and development.

The high-pressure common rail test bench EPS205-Pro is based on the working conditions of the diesel engine ECU, and drives the high-pressure common rail injectors of Bosch, Denso, Delphi, Siemens, Cummins and other brands according to the driving mode required by the engine to realize high-pressure common rail accurate testing of fuel injectors. The test system comes with more than 4,000 sets of high-pressure common rail injector test data, separate user-defined mode, automatic test mode, compensation code generation mode, etc. are designed in the control system, and the data can be stored in groups. It is convenient for maintenance personnel to judge and maintain the working state of the high-pressure common rail injector.
