In this paper,we confirmed the connection between the battery units in power battery system by quoting the reliability theory,and studied whether subjects conform to the reliability model theory by combining with the working principle of the power battery system.We introduced voting redundancy design concept to the study object which do not comply with of the reliability model theory,and set 5 restrained conditions by the Matlab simulation softwares the numerical simulation for power battery system reliability function and further analyzes the data.The experimental results showed that,when x≤0.905,the sample battery system reliability of A was 0,when x =0.995,the battery system reliability was 0.6058.When x =0.9,the reliability of the battery module and battery plate of sample B was about 0.8,and the reliability of the battery system was 0,in order to ensure the high reliability of the whole cell system,the x value was at least 0.99.

本文主要介绍了重型车整车的NOx排放试验方法,并结合DB11965-2013《车载法》标准详细阐述了NOx数据判定方法的具体使用要求.通过试验得出不同车型的整车NOx的排放水平差异较大,并从发动机、行驶工况、后处理器等方面分析了整车的NOx排放特性.
本文采用溶胶凝胶法制备了多种钙钛矿类复合金属氧化物,并采用XRD、SEM、EDX以及TG对其结构、形貌、组成以及催化性能进行了表征.XRD和EDX测试结果表明,合成的物质以类钙钛矿型金属氧化物结构存在;SEM表明,合成的材料微观尺寸在纳米级;TG实验表明,La0.8Sr0.2Cu0.16Fe0.84O3复合氧化物对模拟炭烟燃烧具有最大催化活性,甚至高于贵金属Rh掺杂的La0.7Sr0.3Fe0.7
在严格的排放法规下,选择性催化反应(Selective Catalytic Reduction,SCR)已经成为减少柴油机NOX排放的标准方法.尿素-水溶液的喷射以及与混合器表面和发动机尾气的相互作用控制着氨气的均匀性及边界和混合器表面结晶的生成,这些都影响着SCR的性能和生命周期.计算流体力学(Computational fluid dynamics,CFD)被用来研究一款匹配重型柴油机的含有双
本文旨在研究非道路柴油机进行DPF匹配的策略.参考不同非道路机械保有量占比,选取6台典型非道路机械,使用温度和压力数据采集系统监测六台机械的排气温度和背压,以背压作为DPF再生始点选取的标准,以排气温度作为选择DPF再生方式的依据,为不同的非道路机械选取适宜的DPF系统.之后借助NanoMet3检测DPF前后颗粒物数量,实验工况不仅包括全工况,同时也关注了非道路机械所特有的高低怠速工况,对比分析数
