<p>PURPOSE: A trigger ring structure for checking an angle when driving a starting valve is provided to determine a starting air spray timing of a starting valve for first-starting an engine because a protruded portion inside the trigger ring is read by a proximity sensor. CONSTITUTION: A trigger ring structure for checking an angle when driving a starting valve comprises a first trigger ring and a second trigger ring. If an inner side of the first trigger ring is divided into four parts, the inner side between 0~90°and 90~180°are general shapes, 180~270°and 180~225°are protruded, 225~270°is the general shapes, and 270~360°is protruded. If the inner side of the second trigger ring is divided into the four parts, the inner side between 0~90°and 90~180°are the general shapes, 180~270°is protruded, 270~315°is a general form, and 315~360°is protruded.</p> |
