DEVICE FOR DETERMINING THE TECHNICAL STATE OF CYLINDER-PISTON GROUP OF INTERNAL COMBUSTION ENGINE Russian patent published in 2019 - IPC G01M15/04 

FIELD: machine building.

SUBSTANCE: invention relates to diagnostics of internal combustion engines and is intended to determine the technical state of a cylinder-piston group of engine. Device comprises a hollow body having a lower inlet and an upper outlet, a measuring means responsive to change in the pressure of the exhaust gases, additionally there are provided a receiver equipped with an isolation valve and pressure gauge, modified air filter cover, providing a direct-flow air supply into an inlet manifold of the diagnosed engine, installed in case of using the device for diagnosing engine, without its start-up instead of a standard cover of the air filter of the diagnosed engine and connected to the receiver through the pressure gauge and isolation valve by means of a plastic corrugated pipe, modified cover of an oil filler neck with a pressure gage installed in it.

EFFECT: determination of technical state of the cylinder-piston group of the internal combustion engine without its start-up.
