摘　　要：发动机汽缸压缩压力简称为"汽缸压力",是指活塞压缩至上止点时汽缸内的气体压力。汽缸压力是评价发动机动力性能的一项重要指标,是检查和分析发动机工作性能的重要手段。以丰田花冠1NZ-FE发动机气缸压力检测为例,深入分析并总结汽缸压力偏低或偏高的原因,旨在为汽车检测与维修提供技术参考依据。The engine cylinder compression pressure is simply referred to as “cylinder pressure” and refers to the gas pressure in the cylinder when the piston is compressed to the top dead center. Cylinder pressure is an important indicator for evaluating engine dynamic performance and an important means of checking and analyzing engine performance. Taking the cylinder pressure detection of the Toyota Corolla 1NZ-FE engine as an example, the reasons for the low or high cylinder pressure are analyzed and summarized, aiming at providing technical reference for vehicle inspection and maintenance.
