Injector test bench data provides critical insights into injector performance, influencing engine efficiency, emissions, and reliability. Key tests, including leak tests, maximum fuel injection (VL), idle fuel quantity (LL), mid-speed/emission points (TL/EM), and pilot injection (VE), diagnose issues like fuel leakage, excessive smoke, poor acceleration, or noise. Proper analysis and adjustments, such as correcting shim thickness ensure balanced fuel delivery, lower emissions, and improved engine operation. Accurate testing and calibration are essential for maintaining diesel engine performance and longevity.
