| 1 | 采用里卡多高速直喷式4气门发动机以满足低排放和燃油经济性的要求显示文摘为了研究和证明高速直喷式柴油机的潜力,里卡多公司实施了一项研究并分析每缸4气门燃烧系统性能和排放的计划。分析研究以计算流体力学的研究为基础,以模拟活塞顶燃烧室凹腔内油束与空气的相互作用,并加深对混合过程的理解。试验研究的主要变量包括涡流比、燃烧室凹腔的几何形状、喷油嘴的结构型式、当代先进的转子式电控分配泵和废气再循环的作用。系统的优化过程提供一种固定不变的涡流型式,其制动平均有效压力可达1.5 MPa[15 bar]以上,而BSU(波许烟度单位)却在1.0以下。R49欧洲Ⅱ NO_X水平满足烟度、颗粒排放量和燃油经济性的竞争要求,证明完全按今后发展的欧洲Ⅱ具有极大的开发潜力。车辆排放和燃油耗的模拟表明,此燃烧系统具有满足90年代规定的重型和轻型车排放法规的潜力。 | Needham J R Whelan S 张耀庆 | 1996 | 国外内燃机1996，28，2： | 5 |
