GRADING A PISTON WITH DEPOSITS USING THERMAL SCAN DATA

A method and system for grading pistons with deposits is disclosed. In an embodiment, a piston with an outer surface and deposits upon the outer surface is increased in temperature and thermally scanned. The deposits are identified based on the temperature differences measured with respect to the temperature of the outer surface of the piston. Deposit characteristics can be generated from the identified locations of deposits and the magnitude of temperature difference with respect to the outer surface. The deposit characteristics are recorded and used to grade the pistons. 公开了一种用于分级具有沉积物的活塞的方法和系统。在一个实施例中，具有外表面和在外表面上的沉积物的活塞的温度升高并进行热扫描。这些沉积物是基于相对于该活塞的外表面的温度测量的温度差来识别的。沉积物特性可从所识别的沉积物位置和相对于外表面的温度差大小生成。记录沉积物特性并用于活塞分级。
