"If the engine is turned over too slowly, the unavoidable small leaks past the piston rings and also through the intake and exhaust valves of four-cycle engines will permit a substantial part of the fuel-air mixture to escape during the compression stroke."

如果发动机转速太慢，四行程发动机的活塞环和进排气门就不可避免地有泄漏现象，这会使大量的可燃混合气在压缩行程期间泄漏掉。

In the device, a four-post frame was adopted, two synchronously rotating grip holders were used to realize rigidity rotation of the specimen, and the axial movement of the upper grip holder implemented the tension/compression loading. Positioning accuracy in the axis, radial and circumferential directions were achieved by adopting many advanced and delicate technologies. Measurement on the device indicated that the actual positioning accuracy of the device was better than the kinematic positioning accuracy. Evaluation test on the system indicated that the spatial resolution is better than the pixel size without considering the noise.

该装置采用了四柱式框架结构，采用上下夹头同步转动实现试件相对于框架的刚性转动；上夹头作相对于框架的轴向运动实现对试件的加载；在加载和转动装置中采用了诸多高精技术，实现了试件高精度的轴向定位、径向定位和刚性角度定位；对装置的精度检测表明其实际的定位精度优于运动学定位精度要求；对系统的计量考评初步表明，系统不计噪声的空间分辨率优于X射线CCD的像素10.9μm。
