Abstract
A phaser which has three camshaft start positions at start-up during cranking before the engine can fire. By having three possible start positions of the phaser, there is an increase in flexibility of the cam position at startup during cranking. The three start positions can also be achieved in open loop, reducing the complexity of the control system needed at cranking.
