Description

Известны способы определени  жесткости работы поршневого двигател  внутреннего сгорани  путем измерени  скорости нарастани  давлени  по углу поворота вала.Methods are known for determining the stiffness of an internal combustion piston engine by measuring the rate of increase in pressure over the angle of rotation of the shaft.

Однако определение скорости нарастани  давлени  непосредственно на двигателе сопр жено , как правило, с большими техническими трудност ми.However, the determination of the rate of increase in pressure directly on the engine is usually associated with great technical difficulties.

С целью сокращени  трудоемкости способа измер ют амплитуду и длительность виброимпульсов , формируемых активным горением топлива в камере сгорани , и по отношению замеренных параметров определ ют скорость нарастани  давлени .In order to reduce the laboriousness of the method, the amplitude and duration of the vibration pulses generated by the active combustion of the fuel in the combustion chamber are measured, and the rate of pressure rise is determined using the ratio of the measured parameters.

Дл  реализации предлагаемого способа в зоне провер емого цилиндра устанавливают вибродатчик. Затем устанавливают режим работы двигател , при котором виброимпульсыTo implement the proposed method, a vibration sensor is installed in the zone of the cylinder being tested. Then set the mode of operation of the engine in which the vibration signals

имеют минимальное число помех, и замер ют длительность и амплитуду виброимпульсов, формируемых активным горением топлива, которые характеризуютс  повышенной амплитудой .have a minimum number of interferences, and measure the duration and amplitude of the vibration pulses generated by active combustion of the fuel, which are characterized by an increased amplitude.

Предмет изобретени Subject invention

Способ определени  жесткости работы двигател  внутреннего сгорани , например поршневого , путем измерени  скорости нарастани  давлени  по углу поворота вала, отличающийс  тем, что, с целью сокращени  трудоемкости способа, измер ют амплитуду и длительность виброимпульсов, формируемых активным горением топлива в камере сгорани , и по отношению замеренных параметров определ ют скорость нарастани  давлени .A method for determining the rigidity of an internal combustion engine, such as a piston engine, by measuring the rate of increase in pressure over the shaft angle of rotation, characterized in that, in order to reduce the labor intensity of the method, the amplitude and duration of the vibration pulses generated by the active combustion of the fuel in the combustion chamber and with respect to the measured parameters determine the rate of increase in pressure.
