Abstract
Flow rate characterization for the Duratec 35 EcoBoost engine was conducted at the Powertrain and Fuel Subsystems Laboratory of Ford Motor Company as a key element in the overall calibration for that program. For high-pressure gasoline fuel injection (used in the Direct Injection Spark Ignition [DISI] EcoBoost engine) in which fuel is directly injected in the cylinder, it is important to consider several variables that are not critical for low-pressure fuel injection. In this paper, the effects of fuel pressure, injector pulse width, battery voltage and injection frequency were assessed with respect to injector flow performance (dynamic flow, shot-to-shot variation in mass flow delivery, part-to-part variability in fuel flow, injector delay and split injection performance).
