Quantification of Instantaneous Diesel Flow Rates in Flow Generated By a Stable and Controllable Multiple Injection System (ROSA) 2004-01-0028
A novel multiple injection technique has been applied to a common rail injection system. It is based on a rapidly operating electromagnetic secondary actuator (ROSA) that generates transient current to the primary injector solenoid. The system has produced up to six shots per cycle. A test cell was constructed to evaluate instantaneous flow rates. A laser-based measurement was applied to obtain centerline velocity. Numerous cycles were measured and processed to obtain time/angular resolved values of the flow rate and integrated mass related to each individual injection event. Applied flow metering technique can be widely introduced for calibrations of various high-pressure injection systems.
