Abstract
Methods and systems are provided for controlling an engine system with a variable cam timing device. In one example, the variable cam timing device is operated to adjust engine valve timing differently at engine stop based on whether the engine stop is in response to an operator request or in response to an automatic controller initiated engine stop without an operator request.
