| 4. | The pressure sensor is kistler 6117a46 spark plug piezoelectric pressure sensor 压力传感器为瑞士kistler公司的6117a46型火花塞式气缸压力传感器。 |
| 5. | The load map and wearing maps of the crankshaft journals and crankpin are obtained under various operating conditions 研究表明:气缸压力和转速升高后,曲柄销和主轴颈的磨损均呈现增加趋势。 |
| 6. | The principle of opt - electronic measuring method , essential construction of sensor and major experiments of the paper are explained in chapter 4 第四章介绍了气缸压力的测量方法,并提出了一种测量汽油机燃烧过程火焰传播的新方法? ?光电测量法。 |
| 7. | Eight channels can sample tdc signals , crank angle signals and 4 cylinder pressure signals , two spare channels are reserved . the acquired data need to be analyzed and treated with some mathematic methods , and 软件设定8个通道可以同时采集上止点信号、曲轴转角信号、 1至4气缸压力信号,留有两个备用通道。 |
| 8. | In this paper , a new method of diagnosing cylinder misfire by using kurtosisness of torsional vibration is first introduced . kurtosisness is a parameter which is sensitive to pulse 这一思路提出的来源于:峭度对大幅值和脉冲类信号比较敏感,根据柴油机燃烧的特点,可以假设气缸压力在一个在循环中为一个脉冲激励。 |
| 9. | The simulation results have been compared with experimental data on a single - cylinder direct injection diesel engine . predicted cylinder pressure diagram and the characteristics of nox emission show acceptable quantitative agreement with the experimental data 用zh1115直喷式柴油机的台架试验结果来验证模型预测的精度,预测的气缸压力和no _ x排放浓度与实测数据比较吻合。 |
| 10. | Switzerland . four cylinder pressure data can be sampled and conveniently analyzed to identify the combustion conditions in all cylinders . in order to reduce system errors of sampling channels and insure coherence , sampling channels are calibrated 数据采集系统选用4个瑞士kistler公司生产的6117a46型火花塞式缸压传感器,可以同时采集4个缸的气缸压力数据,非常方便分析发动机各缸的燃烧状况。 |
