Abstract
An internal combustion engine lost motion valve actuation system is disclosed. The system includes a variable length connection means connecting a force imparting means and an engine valve. The connection means may assume plural lengths to provide plural amounts of lost motion. The connection means may provide a maximum amount of lost motion which provides some minimum level of valve actuation suitable for a limp home operation of the engine. The connection means is operable for both engine positive power and engine braking modes of operation.
