已转让给日本Kiki柴油机公司的燃油喷射定时测量装置带有一个脉冲发生器和一个计数器。脉冲发生器产生一组脉冲。当发动机转过某个预定的角度时发出一个脉冲。脉冲系列就是由这种单个脉冲组成的。这些单个脉冲还输入计数器作计数脉冲用。该装置还装备了一个产生第一检测脉冲的装置和一个产生第二检测脉冲的装置。第一个检测脉冲用来表示一个气缸的燃油喷射时间。第二个检测脉冲表示对应的曲柄到达其上死点的时间。计数器的计数动作是由两个检测脉冲控制的。计算器只在出现第一个检测脉冲和出现第二个检测脉冲之间的时间间隔内才动作。因
The fuel injection timing measurement unit, which has been transferred to Kiki Diesel Co., Japan, has a pulse generator and a counter. The pulse generator generates a set of pulses. A pulse is emitted when the engine turns a certain angle. Pulse series is composed of this single pulse. These single pulses are also input to the counter for counting pulses. The apparatus is also equipped with a means for generating a first detection pulse and a means for generating a second detection pulse. The first test pulse is used to indicate the fuel injection time for one cylinder. The second detection pulse indicates when the corresponding crank reached its top dead center. The counting action of the counter is controlled by two detection pulses. The calculator will only operate within the time interval between the occurrence of the first detection pulse and the occurrence of the second detection pulse. because
