Abstract

An engine control system and method monitors torque increase during cylinder deactivation for a displacement on demand engine. A timer is started at cylinder deactivation. A controller adjusts throttle position and determines whether cylinder deactivation completes within a predetermined time. The controller adjusts throttle position based on the status of an enable condition. The controller determines if engine speed and vehicle acceleration are each within a threshold. The controller operates the throttle in a preload operating mode if the enable condition is met and operates the throttle in a normal operating mode if the enable condition is not met.
