汽车压缩比：引擎性能的关键指标英文双语对照

汽车引擎的压缩比是什么？

汽车引擎的压缩比是指发动机缸内工作介质（空气和燃料混合物）的体积与压缩最大容积的比值。这一指标直接关系着发动机性能和燃油利用率。

为什么压缩比如此重要？

压缩比直接影响着引擎的燃烧效率和动力输出。较高的压缩比能够提高燃烧效率，从而使引擎在相同燃料条件下获得更大的动力输出。

不同压缩比对汽车性能的影响

较高的压缩比通常会提高发动机的动力性能，但也会增加爆震的风险；而较低的压缩比则会减少爆震的风险，但相对会牺牲一定的动力输出。

如何选择适合的压缩比？

选择适合的压缩比需要综合考虑车辆用途、燃料类型、发动机材质等因素。一般来说，高性能车辆会采用较高的压缩比以获得更大的动力输出；而普通乘用车则会追求燃油经济性，采用较低的压缩比。

结论

汽车压缩比是衡量引擎性能和燃油利用率的重要指标，选择适合的压缩比可以在保证动力输出的情况下提高燃油经济性，是汽车设计和制造中的重要考量因素。

What is the compression ratio of car engine?

Of car engineCompression ratioIt is to point to to medium works inside engine crock (air and fuel mixture) bulk and the specific value that reduce the largest volume. This one index is concerning directly engine function and fuel utilization rate.

Why is compression ratio so important?

Compression ratioAffecting the combustion efficiency of engine and dynamical output directly. Higher compression ratio can improve combustion efficiency, make engine obtains bigger dynamical output below same fuel condition thereby.

The influence of different compression ratio to car function

TallerCompression ratioConnect regular meeting to improve the dynamical performance of engine, but also can increase explode the risk of shake; And inferior compression ratio can decrease explode the risk of shake, but relative to meeting sacrifice certain power is outputted.

How to choose suitable compression ratio?

Choose to suitCompression ratioNeed considers type of car utility, fuel, engine material integratedly to wait for an element character. Generally speaking, high-powered car can use higher compression ratio to be outputted in order to gain bigger momentum; And common by can seek fuel economy with the car, use inferior compression ratio.

Conclusion

CarCompression ratioIt is the main index that measures engine function and fuel utilization rate, the compression ratio that the choice suits is OK fuel economy improves below the circumstance that makes sure motivation is outputted, it is a car in design and be being made important think element.
