Abstract
Изобретение может быть использовано в отрасл х народного хоз йства, в которых занимаютс эксплуатацией и техническим обслуживанием двигателей внутреннего сгорани (ДВС). Цель изобретени состоит в расширении функциональных возможностей способа диагностировани ДВС по расходу газов, прорывающихс в картер, и охвате при диагностировании большего числа систем двигател , а также упрощении работ при технической диагностике ДВС. Воздух поступает во впускной коллектор 2 двигател 1, отработанные и прорывающиес в картер газы выход т из выпускного коллектора 3 и заливной горловины 4. Дл замера расхода поступающего воздуха во впускной коллектор служит расходомер 5, а количества отработанных и прорывающихс газов - расходомеры 6 и 7. О техническом состо нии двигател внутреннего сгорани суд т по отклонению величины коэффициента технического состо ни ДВС. 1 ил.The invention can be used in national economy branches, in which they operate and maintain internal combustion engines (ICE). The purpose of the invention is to expand the functionality of the method for diagnosing ICEs in terms of the flow rate of gases erupting into the crankcase, and coverage when diagnosing a larger number of engine systems, as well as simplifying work in the technical diagnostics of ICE. Air enters the intake manifold 2 of the engine 1, exhaust gases and burst into the crankcase flow from the exhaust manifold 3 and the filler neck 4. Flow meters 6 and 7 serve to measure the flow of incoming air into the intake manifold. The technical condition of the internal combustion engine is judged by the deviation of the value of the coefficient of the technical condition of the engine. 1 il.
