A method for operating an engine in a vehicle, the engine having at least a cylinder, the method comprising:
- generating engine braking torque to stop rotation of the engine in a desired range by opening and closing at least an electrically actuated valve of the cylinder more than once during a cycle of the cylinder.
A method for operating an engine in a vehicle, the engine having at least a cylinder, the method comprising:
- generating engine braking torque to stop rotation of the engine in a desired range by opening and closing at least an electrically exhaust actuated valve of the cylinder more than once during a cycle of the cylinder.
A method for operating an engine in a vehicle, the engine having at least a cylinder, the method comprising:
- generating engine braking torque to stop rotation of the engine in a desired range by opening and closing at least an electrically exhaust actuated valve of the cylinder more than once during a cycle of the cylinder, and wherein another cylinder operates with one of intake valves and exhaust valves held closed and the other of intake valves and exhaust valves held open during the cycle.
