| 摘要 |
The present invention relates to a valve stroke measurement system (1) which enables the valve stroke amount of internal combustion engines to be measured relative to time by processing digital images received from the high speed camera in valvetrain test mechanism and essentially comprises at least one test mechanism (2) which enables the valve in the internal combustion engines to be operated independent from the engine, at least one test valve (3) the valve stroke amount of which is to be measured in the test mechanism (2), and which is marked such that it will be distinguished from the objects and parts around it, at least one reference valve (4) which is marked in a different marker in the test mechanism (2), at least one camera (5) which is preferably fixed in vertical angle with the valves moving in the test mechanism (2), at least one control unit (6) which is adapted to calculate the stroke amount of the test valve (3) relative to time by calculating the locations of the markers on the test valve (3) and the reference valve (4) and their locations relative to each other. |
