Abstract
A valve actuation system for actuating at least one of two or more engine valves in an internal combustion engine comprises at least one motion source including a first motion source configured to provide an exhaust main valve event. A valve train for conveying valve events from the at least one motion source to the two or more engine valves comprises a lost motion component for selectively conveying valve events to the at least one of the two or more engine valves. A phasing assembly is configured to advance a phase of at least the first motion source and the exhaust main valve event. The at least one motion source is configured to provide a recompression relief valve event to the at least one of the two or more engine valves when the phase of the exhaust main valve event is advanced.
