Abstract

See full text

A valve actuation system comprises a cylinder deactivation controller operatively connected to and in fluid communication with intake and exhaust deactivators for at least one cylinder. The valve actuation system further comprises an engine braking controller operatively connected to and in fluid communication with the engine braking actuators for the at least one cylinder. A braking-dependent deactivator controller is disposed between and in fluid communication with the cylinder deactivation controller and the intake deactivators, and in fluid communication with the engine braking controller via a control input. The braking-dependent deactivator controller is configured, in a first state based on its control input, to permit hydraulic fluid flow in hydraulic fluid control passages for the intake deactivators when in a non-1.5-stroke engine braking mode and, in a second state, to vent the hydraulic fluid control passages for the intake deactivators when in a 1.5-stroke engine braking mode.
