在柴油机和内燃机气缸中测量气缸压力的最不利条件在于,与变送器连接在一起的气缸腔壁上所具有的350～500℃高温。进入腔体的气体也大体是这样的平均温度。在此条件下,快速流动过程的记录及其测量只有在变送器的敏感元件急剧冷却时才有可能。
The most unfavorable condition for measuring cylinder pressure in the cylinders of diesel and internal combustion engines lies in the high temperatures of 350 to 500 ° C on the walls of the cylinder connected to the transmitter. The gas entering the chamber is also generally at such an average temperature. In this condition, the recording of the fast-flow process and its measurement are only possible when the transmitter’s sensitive components cool down sharply.
