本文对直喷式双燃料柴油机爆震现象的模拟进行了某些探索性的研究,该项研究以甲烷为主要燃料,同时顾及引燃油对燃烧过程的影响,并通过改善热力学和化学反应动力学模型及选用合理的参数,取得与试验较为一致的满意结果,初步达到了预测爆震的目的。 In this paper, some exploratory studies have been made on the simulation of the knocking phenomenon of direct injection dual-fuel diesel engines. The study uses methane as the main fuel, taking into account the influence of the pilot fuel on the combustion process and by improving the thermodynamics and chemical reaction kinetics Model and selection of reasonable parameters to obtain satisfactory results consistent with the test, initially reached the purpose of predicting knocking.
