Deck/Measuring tool/652601-652609 ENGINE INDICATOR MAX 350 RPM

中文品名：发动机指示器, 最高350转/分钟

The engine indicators are the pressure measuring instruments for reciprocating engines.  They record the pressure change in the cylinders of internal combustion engines, reciprocating steam engines and gas or air compressors.  The results are used for checking uniform and efficient performance of each cylinder, thus to assess the engine characteristics and to calculate the generated horse-power.

发动机指示器是往复式发动机的压力测量仪器。它们记录内燃机、往复式蒸汽机和气体或空气压缩机的气缸内的压力变化。其结果用于检查各缸的均匀和高效性能，从而评估发动机特性并计算产生的马力。
