This paper describes the concept, analysis and preliminary rig proving of a 2-mode mechanical variable-valve-actuation system, “Latchcam”, designed initially for prototype bucket-tappet overhead-cam applications. The rig-test data allows the prototype Latchcam performance to be compared to a state-of-art 2-mode system in a current cylinder-head application. Some general design implications and issues are reviewed.
