Abstract:Stringent emission levels challenge automotive industries to come up with innovative ways of improving existing technologies. In advancing diesel engine technology, the key factor lies in further developing a piezoelectric fuel injector in the common-rail system. A direct acting piezoelectric fuel injector prototype for the common-rail system was developed to preserve the lifetime of the actuator, achieve an adequate needle lift, and response quickly. Through analytical work and ANSYS simulations, problems wer… Show more
