Authors Abstract
Content
The paper describes the development of a hydraulic variable valve motion system which has been used successfully to study the relationship between rate of exhaust valve opening and exhaust pulse energy with reference to exhaust turbocharging. The device may be configured to provide variation of timing, rate of opening or closing, or lift. Each of these variations could be achieved independently, for example, the start of valve opening could be varied without altering either the rate of opening or the full lift. The device is described in detail and preliminary experimental results are given. An alternative configuration in which the variation of motion may be achieved digitally is described.
