Spark retard control during cylinder transitions in a displacement on demand engine

An engine control system and method calculates spark retard during cylinder activation and deactivation for a displacement on demand engine. A torque reduction calculator calculates a torque reduction signal based on desired and measured air per cylinder. A spark retard (RTD) calculator generates a...

Summary:An engine control system and method calculates spark retard during cylinder activation and deactivation for a displacement on demand engine. A torque reduction calculator calculates a torque reduction signal based on desired and measured air per cylinder. A spark retard (RTD) calculator generates a RTD signal based on the torque reduction signal.
