一、由示功图得到的有关燃烧的知识选用内燃机示功器的工作,即使在计测技术发达的现在,也决不是容易的。从经过努力而取得的示功图中得出最大限度的知识,如不充分利用,那么这些知识是无价值的。反之,当没有可能引出那些利用价值时,便可不必费力去选择示功器了。另外,选用精度良好的示功器是一件相当困难的工作,但尽管如此,也要根据要求降低精度选择之。由示功图得到的有关燃烧的知识,有如下举出的一些,即:燃烧最高压力、着火位置与着火延迟、压升率、压力变化过程、爆震、燃烧振动的有无、燃烧终了时间、燃烧效率、放 First, the knowledge obtained from the Kung-fu charter The choice of internal combustion engine dynamometer work, even in the current measurement technology developed, it is by no means easy. The maximum amount of knowledge derived from hard-working diagrams, if not fully exploited, is worthless. Conversely, when it is not possible to elicit those values, you do not have to bother with choosing a demonstrator. In addition, the choice of a good precision dynamometer is a very difficult task, but nevertheless, it is also required to reduce the accuracy of the choice. The knowledge about combustion obtained from the dynamometer is as follows: maximum pressure of combustion, ignition position and ignition delay, rate of pressure rise, pressure change, detonation, combustion vibration, end of combustion time , Combustion efficiency, put
