The intensity of the gas backflow and axial swirl ond the dilution in the afterburner are enhanced by increasing the air-to-fuelratio, and then the combustion efficiency is improved.
提高空燃比，可增强补燃室中燃气的回流和轴向涡流强度，加大掺混力度，从而提高燃烧效率。

Still, the new engine gets a 14-to-1 ratio for fuel-air compression, compared with the more common 10-to-1 ratio for engines.
新款引擎的燃料空气压缩率高达14比1，而一般的引擎只有10比1。

The paper also introduces how to adjust the carburetor to get an ideal air-fuelratio.
