    • Volumetric metering equipment having a plurality of inputs connected to respective lines (40) of a fuel injection pump under test when the equipment is in use. A piezoelectric point of injection detector (54) with a micro controller (60) provides a measure of the time taken between two successive injections. Means (124g) are provided to compute the expected time taken for the equipment to reach a temporary static condition following the first of those injections, and means (46,60, 102, 104) to reduce the number of lines the fluid from which is being metered at any given instant in the event that the measured time is less than the computed time.
    • 容量计量设备具有多个输入端,当设备使用时,该输入端与被测燃料喷射泵的相应管线(40)连接。 具有微控制器(60)的压电喷射点检测器(54)提供两次连续喷射之间所花费的时间的量度。 提供装置(124g)以计算设备在第一次注射之后达到临时静态状态所需的预期时间,以及用于减少流体从其中流出的管线数量的装置(46,60,102,104) 在测量时间小于计算时间的情况下在任何给定时刻被计量。
