调车内燃机车由于工况不稳定 ,不仅使排放的有害物质比干线内燃机车多出好几倍 ,而且由于燃烧不完全 ,使气缸活塞组的动负荷和热负荷也大为增加。为了解决这一问题 ,提出一种向柴油机增压集流管中供送压缩空气的辅助供气系统 ,并在ЧМЭ3型调车内燃机车上使用。结果表明 :不仅有害物质减少了 30 %～ 4 0 %,而且燃油消耗率也降低了 9%。
Shunting diesel locomotives due to unstable conditions, not only to make the emission of harmful substances several times more than the main line diesel locomotives, but also because of incomplete combustion, the cylinder piston assembly dynamic load and heat load also greatly increased. In order to solve this problem, an auxiliary air supply system for supplying compressed air to a diesel engine pressurized header is proposed and used on a ЧМЭ3 shunting diesel locomotive. The results showed that not only the harmful substances were reduced by 30% ~ 40%, but also the fuel consumption rate was reduced by 9%.
