AI Technical Summary
Existing engine valve timing measurement technologies suffer from problems such as measurement lag caused by hydraulic tappets, lack of correlation between angle and displacement in traditional methods, strong subjectivity, high cost, and insufficient versatility, making it difficult to achieve high-precision, high-repeatability, and low-cost measurements.
It adopts a purely mechanical dual-reference linkage design, constructing a "piston-measuring rod-dial gauge" sensing chain through rigid tappets, and combining the dial and crankshaft adapter plate to establish a synchronous relationship between crankshaft angle and valve displacement, thereby achieving accurate measurement.
It improves the accuracy and repeatability of measurements, reduces composite errors, is applicable to various engine structures, is low in cost and highly adaptable to the environment, and is suitable for final inspection on the production line, R&D verification and maintenance scenarios.
