Electronic hydraulic lifter apparatus and methods, with the apparatus including a lifter body and a piston disposed at least partially within the lifter body and configured to translate longitudinally with respect thereto. The apparatus further includes a first fluid reservoir disposed at least partially within the lifter body, the piston, or both and configured to receive an end of the piston, and a smart fluid disposed within the first fluid reservoir and configured to communicate with at least the end of the piston. The apparatus also includes an electrical connection coupled to the first fluid reservoir and operatively communicating with the smart fluid, with the electrical connection being configured to vary a viscoelastic property of the smart fluid by applying a field thereto. |
