Abstract:
A method to start an internal combustion engine having a variable event valvetrain is provided. The method includes increasing the speed of said internal combustion engine during a start from a stopped position after a request to start said internal combustion engine. The method may further include increasing an intake valve lift amount, of at least a cylinder during said start while said internal combustion engine speed is increasing. The method may further include only enabling fuel flow to said cylinder when said intake valve lift amount reaches a predetermined level.
