At ANTAIOS, every engine undergoes strict and scientific bench testing before leaving the factory to ensure its performance and reliability meet or even exceed customer expectations. The complete engine bench test includes 8 steps:
1.Test Preparation
Ensure that the engine dynamometer, fuel consumption meter, data acquisition system, and various temperature, pressure, and speed sensors are calibrated and functioning properly.
2.Engine Installation and Calibration
Lifting and Positioning: Use lifting equipment to carefully place the engine on the test bench and connect it to the dynamometer via a flexible coupling.
3.Connecting Systems’ Pipelines and Wiring
Connect the engine’s intake and exhaust pipes, along with all other related pipelines, in accordance with the specified procedures. Install all necessary sensors and wiring harnesses to ensure proper function.
4.Startup and Preheating
The dynamometer drives the engine to provide initial lubrication to the moving parts. After startup, the engine runs for several minutes with no load or very low load, followed by preheating the coolant to the specified temperature.
5.Performing Various Performance Tests
Conduct external characteristics testing, emission certification testing, durability and reliability tests, load cycling tests, and more to comprehensively assess performance from multiple aspects.
6.Data Recording and Monitoring
An automated data acquisition system continuously records data from all sensors. Engineers monitor key parameter curves (such as power, torque, etc.) in real-time from the control room.
7.Post-Test Inspection and Processing
Check for any oil or coolant leaks. Inspect fuel pipe connections and injector seals for any fuel leakage. Perform internal disassembly inspections and precise measurements.
8.Issuing Test Report
Summarize all inspection results, measurement data, photos, and analytical conclusions to produce a detailed post-test inspection report.
