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。

It is ideally packaged for the integration of the high-performance, zero-emission technology: by way of example, the four electric motors and the two transmissions can be positioned as close to the four wheels as possible and very low down in the vehicle.

In other words, a country would decide how its land-use carbon emission or absorption would be likely to change in future, and then to measure actual performance against that baseline.
