【摘要】 利用AVL BOOST软件建立的小缸径增压中冷柴油机计算模型对该机整机性能进行模拟计算,获得了标定转速时100%、75%、50%、25%、10%负荷工况点时的性能参数。结果表明,模拟计算结果与实验结果吻合良好,验证了模型的可靠性,并分析了计算误差。利用验证的模型,探讨喷油提前角对柴油机性能的影响,从而为后续研究提供了理论依据。更多还原

【Abstract】 AVL BOOST software was used to make a calculation model of a D.I.diesel engine with small cylinder bore.The performance parameters of 100%,75%,50%,25%,10% of full load at rated speed were studied.The results show that the simulation results tallies well with the experimental results,the model was reliable,and the computational error was studied.Using this verified model,we studied the injection advance angle’s influence on the performance of this diesel engine.The results can provide the theoretical basis for following study.更多还原
