The cost of maintaining aeroplanes is still considerable. It concerns especially operation cost where fuel is a substantial part. At the moment the special 100LL gasoline is used to fuel aircraft piston engines. It is about 20% more expensive than ES95 gasoline featuring comparable properties.The article shows the results of test-bed research conducted on the radial piston aircraft engine fuelled by aircraft 100LL gasoline and automotive ES95 gasoline. The object of research was ASz-62IR engine by WSK PZL-Kalisz that was equipped with an experimental fuel injection system. Power, fuel consumption, head temperatures and indicated pressure in cylinders were analysed in the selected typical operating points. The testing was carried out in steady state. It was proved that it is possible to exchange fuels with no engine power loss and merely an insignificant increase of fuel consumption but with significant increase of IMEP cycle-to-cycle variation. 相似文献

一种主从式微机红外测温系统 总被引:1,自引:0,他引:1
本文提出一种针对机车模拟加载测试台的微机红外测温系统,该系统以热电堆红外传感器件作为主要的温度探测器件,由单片机8031集总采集,通过串行通信与PC机构成主从式控制系统,从而可实现温度和包括其它信息参数在内的远程自动检测或故障诊断。文章讨论和介绍了这一系统的具体设计。 相似文献
