S195柴油机掺氢燃烧在所有工况下,烟度都有新降低。从烟度、功率两方面都较优考虑:热量比在4％～10％范围内较合适;θ=11℃A处烟度下降率出现一个谷值;压缩比ε=18.6和转速n=1800r/min时烟度较低(原机标定值:ε=20,n=2000r/min)。
S195 diesel engine with hydrogen combustion in all conditions, the smoke has a new decrease. From the perspective of smoke and power, it is considered that the heat ratio is more suitable in the range of 4% -10%, and a valley exists at the rate of θ = 11 ℃ A; the compression ratio ε = 18.6 and the speed n = 1800r / min when the smoke is low (the original calibration value: ε = 20, n = 2000r / min).
