Description

щее звено 6 с конденсатором 7. Следовательно , в конце каждого рабочего цикла напр жение на конденсаторе 7 пропорционально среднему индикаторному давлению цикла. В конце каждого цикла конденсатор 7 разр жаетс  через ключ 8, который может быть вьшолнен в виде транзистора (см. фиг. 2). В этом случае измер етс  напр жение, а следовательно , и среднее индикаторное давление за каждый рабочий цикл, так как конденсатор 7 разр жен к началу новото цикла.A common link 6 with a capacitor 7. Therefore, at the end of each operating cycle, the voltage across the capacitor 7 is proportional to the average indicated pressure of the cycle. At the end of each cycle, the capacitor 7 is discharged through the switch 8, which can be implemented as a transistor (see Fig. 2). In this case, the voltage is measured, and consequently, the average indicator pressure for each duty cycle, since the capacitor 7 is discharged to the beginning of the new cycle.

На фиг. 3 показаны изменение текущего давлени  Р поршневой машины в зависимости от положени  поршн  (крива  10) и зависимость напр жени  Uc па конденсаторе 7 интегрируюшего звена 6 от положени  поршн  (крива  И), ордината 12 которой соответствует среднему индикаторному давлению данного цикла.FIG. Figure 3 shows the change in the current pressure P of the piston machine depending on the position of the piston (curve 10) and the dependence of the voltage Uc on the capacitor 7 of the integrating link 6 on the position of the piston (curve I), the ordinate 12 of which corresponds to the average indicator pressure of this cycle.

Использование предлагаемого устройства при испытани х поршневых машин, в частности двигателей внутреннего сгорани , позвол ет непосредственно определ ть среднее индикаторное давление каждого последовательно протекающего цикла, что неОбходимо при анализе и доводке рабочего процесса наThe use of the proposed device in testing piston machines, in particular internal combustion engines, makes it possible to directly determine the average indicator pressure of each successively flowing cycle, which is necessary when analyzing and fine-tuning the working process
