ANALYSER OF OPERATION OF SYSTEMS OF INTERNAL COMBUSTION ENGINE Russian patent published in 2009 - IPC G01M15/05 

FIELD: physics; measuring.

SUBSTANCE: invention concerns devices for measuring of parametres of systems of an internal combustion engine and can be used for diagnosing of internal combustion engines. The third and fourth counters, the second plan of sample-storage, additional remembering condensers, the compression indicator are in addition entered into the analyser of operation of systems of an internal combustion engine in cylinders of the drive, the second key of guidance and the exit of the amplifier of the shaper is joined to an inlet of dump of the third counter and the second exit of the detector of a current of a starter - from it's numerable exit and the second plan of sample-storage is joined by an inlet and the second plan of sample-storage to which remembering condensers on number of cylinders of the drive are included, to an inlet of the indicator of a compression in drive cylinders, numerable inlet of the fourth counter is related through the second key of guidance to the case and its exits with inlets of the second plan of sample-storage.

EFFECT: increase of informativeness at diagnosing of straggling of a compression in drive cylinders, i.e. introduction of the specified devices allows to check in addition at diagnosing straggling of a compression on each cylinder and to localise the unworkable cylinder.
