摘要
在保证标定转速时ην不降低的前提下,降低最大ην时对应的转速,从气体振动角度出发,设计了具有一定实用价值的串、并联谐振进气系统,从而提高了最大扭矩点附近的ην,改善了低速时的燃油经济性。本文着重对面广量大的S195柴油机提出了具体的改进措施。
Without decrease in volumetric efficiency ηv at rated speed, practicable series and parallel resonant inlet systems are designed with gas vibration to lower the speed at maximum ηv. so as to increase ηv in the ricinity of maximum torsion and improve fuel economy. Emphasis is laid oa measures to modify diesel Sl95 in common use in China.
