Abstract

СПОСОБ ОПРЕДЕЛЕНИЯ СКОРОСТИ ИЗНОСА ЦИЛИНДРОВЫХ ВТУЛОК ДВИГАТЕЛЕЙ, заключающийс  в том, что эксплуатируют двигатель, измер ют среднее эффективное давление газов за цикл, обороты двигател , максимальное давление сгорани  и рассчитывают среднюю скорость перемещени  поршн , с учетом которой оценивают износ, отличающийс  тем, что, с целью повыщени  достоверности результатов, измер ют температуру отработавших газов на выходе из цилиндра и определ ют обобщающий параметр износа по формуле -- Г-сгде Ре.-среднее эффективное давление за цикл; t температура отработавших газов на выходе из цилиндра; Р - максимальное давление сгорани ; С - средн   скорость поршн , с учетом которого определ ют износ цилиндровых втулок.A METHOD FOR DETERMINING THE WEAR RATE OF CYLINDER ENGINE SLEEVES, which consists in operating the engine, measuring the average effective gas pressure per cycle, engine speed, maximum combustion pressure, and calculating the average piston movement rate, taking into account wear and tear, characterized by In order to improve the reliability of the results, the exhaust gas temperature at the cylinder exit is measured and a generalized wear parameter is determined by the formula — G — where Ge is. The average effective pressure for chi cl; t is the exhaust gas temperature at the cylinder outlet; P - maximum pressure of combustion; C is the average piston speed, which is used to determine the wear of cylinder liners.
