Then in order to suppress smoke and save energy, adjustments of fuel flow, injectors, valve clearance and cylinder compression, etc, are performed.

从供油量、喷油器、气门间隙和气缸压力等方面进行调整，以达到消烟节能的目的。

Its Variable Compression Engine can alter its compression ratio (the volume in a cylinder when the piston is up compared with the volume when it is down) from 14-1 to 8-1, depending on the circumstances.
