Description
Изобретение относитс к области технической диагностики и может быть применено при эксплуатации двигателей внутреннего сгорани .The invention relates to the field of technical diagnostics and can be applied in the operation of internal combustion engines.
Известны способы определени технического состо ни цилипдро-поршневой групны двигател по расходу газов, уход щих в картер из камеры сгорани .Methods are known for determining the technical condition of a cylinder-piston engine group by the flow of gases leaving the crankcase from the combustion chamber.
Однако эти способы не обеспечивают своевременного вы влени степени износа отдельных цилиндров.However, these methods do not provide timely detection of the degree of wear of individual cylinders.
Предлагаемый способ отличаетс тем, что расход газов замер ют на заданном скоростном и нагрузочном режимах при последовательном выключении из работы каждого из цилиндров. Это позвол ет сократить трудоемкость .The proposed method is characterized in that the gas flow rate is measured at a predetermined speed and load conditions with sequential shutdown of the operation of each of the cylinders. This reduces labor intensity.
При определении степени изношенности какого-либо цилиндра сначала замер ют количество газов, уход щих в картер при работе двигател на всех цилиндрах, а 3|атем цри работеWhen determining the degree of deterioration of a cylinder, first measure the amount of gases escaping into the crankcase when the engine is running on all cylinders, and 3
двигател с выключенным путем декомпрессировани контролируемых цилиндром. Расход газов, в картер из камеры сгорани через кольцевые уплотнени поршн контролируемого цилиндра определ ют но разности количества газов, уход щих в картер нри работе двигател на всех цилиндрах, и количества газов, уход щих в картер при работе двигател с выключенным путем декомпрессировани контролируемым цилиндром.engine with decompression controlled by cylinder. The flow of gases into the crankcase from the combustion chamber through the annular seals of the controlled cylinder piston is determined by the differences in the amount of gases leaving the crankcase when the engine is running on all cylinders and the amount of gases leaving the crankcase when the engine is turned off by decompressing the controlled cylinder.
