Abstract: In electronic control diesel fuel injection systems of
modern diesel engines, the high-speed, powerful solenoid valve is the
key element to determine the performance of the systems. And there is a
thin gap of fuel film exists between the armature and solenoid. This
squeeze film directly influences the dynamic response characteristics of
the valve. An analysis by laminar flow is undertaken to evaluate squeeze
film behavior and determine optimum venting arrangement for improved
valve performance.
Key words: Electronic control diesel fuel injection system High-speed
powerful solenoid valve Squeeze film
