Abstract
A system for monitoring operation of an internal combustion engine having a rocker arm assembly for actuating an engine valve is disclosed. The rocker arm assembly includes a first arm with a first end, a second arm also having a first end pivotally connected near the first end of the first arm, a latch that when latched secures the first arm relative to the second arm in a latched mode, and when unlatched allows the first arm to move relative to the second arm in an unlatched mode. The system also employing a sensor attached to one of the first and second arms that can detect when the arms are moving relative to each other, and adapted to provide a signal indicating the sensed movement.
Claims16
A system for monitoring operation of an internal combustion engine, comprising:
- a rocker arm assembly for actuating an engine valve, the rocker arm assembly comprising:
- a first arm having a first end;
- a second arm having a first end, the second arm pivotally connected near the first end of the first arm along a pivot having a pivot axis;
- a latch that when latched secures the first arm relative to the second arm in a latched mode, and when unlatched allows the first arm to move relative to the second arm in an unlatched mode;
- and
- a sensor positioned in proximity to the first end of the first arm, the sensor adapted to detect motion of the first and second arms relative to each other, and further adapted to provide a signal indicating the detected motion.

- a latch that when latched secures the first arm relative to the second arm in a latched mode, and when unlatched allows the first arm to move relative to the second arm in an unlatched mode;
- and
- a means for detecting relative motion of the first arm and the second arm, wherein the means for detecting relative motion is positioned at the first end of at least one of the first arm or the second arm.
