摘要
分别在发电机工况和推进工况下 ,通过在 1台 413 5G柴油机上试验研究喷油正时变化对柴油机排气中有害成分的影响。试验结果表明喷油正时适当延滞调整可以降低柴油机排气中NOx排放浓度 。
Under the impelling and generating work condition separately,the experimental investigations about influence of injection timing upon harmful ingredient of exhaust gas are conducted by means of a type of 4135G diesel engine.The experiments indicate that the density of NOx in exhaust gas could be decreased if the time of injection be adjusted properly,and that fuel-consumption rate and smoke intensity could not be influenced badly.
