摘要
根据4105防爆柴油机的结构参数及其性能实验结果,建立了工作模型,分析了压缩比、供油提前角和配气相位对燃油消耗率、充气效率、残余废气系数以及动力性能的影响,并对压缩比、供油提前角和配气相位进行了优化。优化结果表明,适当提高压缩比、调整合适的供油提前角和配气相位可提高动力性,降低防爆柴油机的燃油消耗率。
The working model of explosion-proof diesel engine is built up on the basis of structural parameters and results of performance experiments on explosion-proof 4105 diesel engine. The effects of compression ratio, fuel injection advance angle, valve phases on fuel consumption rate, air-charged efficiency, residual gas coefficient, and dynamic performance are analyzed and optimized. The results show that the dynamic performance will be improved and the fuel consumption rate will be reduced by increasing compression ratio, rectifying fuel injection advance angle and valve phases properly.
