Fig. A_2. Injection timing device: during actuation of an advance (max value 4.5°).
The oil (yellow) goes into the system and moves the plunger (blue) that activates the camshaft anticlockwise.
Fig. A_3. Injection timing device: moving from actuation of an advance to resting position.
The oil (yellow) goes out and releases the spring to move the plunger (blue), which in turn activates the camshaft
clockwise.
Our system is able to actuate any intermediate advance, regulating the oil pressure. When the set level is reached, the oil exerts
the right force to compress the spring at the right height to move the plunger appropriately, thus achieving the required rotation
(angular advance).
