摘要
本文探索了一种适合于甲烷柴油双燃料直喷式柴油机的燃烧模型,用含有14种化学成份的32个化学反应方程来模拟稀薄和接近理想甲烷氧气混合比时的燃烧过程。计算和实测结果表明,此模型能较满意地预示双燃料柴油机的性能,又为设计和研制新型双燃料柴油机提供有价值的信息。
In this paper a combustion model is developed for a duel fuel direct injection diesel engine in which 'the methane is supplied through the inlet manifold and the diesel fuel through the fuel injection system. A scheme of 32 elementary reactions involving 14 species was simulated for the combustion of lean and near stoichio-metric mixture of methane and oxygen, while the combustion of a small pilot diesel fuel was controled by 'heat release' model. The calculated results show that the model could satisfactorily predict the combustion process and the performances of the duel fuel engine.
