| 摘 要： | 介绍了基于进气歧管压力的汽油机进气模型,讨论了实际运用中进气模型的表达式.该进气模型将缸内残留废气分为驻留废气与回流废气两部分,在大负荷工况对进气歧管压力-进气效率转换系数加入非线性修正,更符合实际进气规律.在发动机上进行试验研究,结果表明,该进气模型能准确计算发动机进气量.

| Abstract: | The charge model of gasoline engine based on intake manifold pressure was introduced and the expression of the charge model in actual application was discussed.In the charge model,the residual exhaust was divided into resident exhaust and refluent exhaust.In high loads,the nonlinear correction of conversion coefficient between intake manifold pressure and charge efficiency was needed to agree with the actual charge rule.Based on the model,the experiment was carried out.The result shows that the charge model... |
