internal combustion engine performance

With the variations of altitude, atmospheric pressure changes, resulting in corresponding changes of internal combustion engine performance.

随着海拔变化，大气状态随之变化，导致内燃机性能相应变化。

The performance and emission characteristic of internal-combustion engine is decided by the reciprocity of the intake flow, in-cylinder mix and combustion process.

内燃机的性能与排放特性主要由进气流动、缸内混合和燃烧过程间复杂的相互作用所决定。

The flow field uniformity inside the exhaust cleaner of internal combustion engine has very important effect on the use performance and service life of the exhaust cleaner.

内燃机排气净化器内的流场均匀性对净化器的使用性能及使用寿命具有非常重要的影响。
