Core Testing Standards (Pass/Fail Criteria)
A good fuel injector must pass the following five critical test phases on a common rail test bench:
-
Tightness & Leakage Test (Static/Dynamic Leakage):
-
Standard: No visible dripping or fuel drops at the nozzle tip under high pressure. Internal back-leakage (return flow) must remain within the manufacturer's specified cubic centimeter (cc) limit.
-
-
Full Load (VL) / Maximum Discharge Test:
-
Standard: Measures the fuel delivery volume when the injector is fully open at peak operating pressure. The output volume must match the target injection chart.
-
-
Idling (LL) Test:
-
Standard: Tests stable fuel delivery at minimum engine speeds. Low delivery causes rough idling; excessive delivery causes smoke and engine shaking.
-
-
Pre-Injection (VE) / Pilot Injection Test:
-
Standard: Evaluates the tiny amount of fuel injected right before the main combustion event (critical for reducing diesel engine noise). Strict volume accuracy is required here.
-
-
Emission / Part Load (EM) Test:
-
Standard: Simulates mid-range driving conditions to ensure emissions and fuel economy meet environmental standards.
