METHOD FOR OPERATING THE ENGINE (VERSIONS) AND CARTER VENTILATION SYSTEM Russian patent published in 2017 - IPC F01M13/02 F02D41/22 F02B77/08 

FIELD: engines and pumps.

SUBSTANCE: with by the electronic controller coupled to the engine sensors and actuators, determine the location of damage to the crankcase ventilation system on the basis of the amplitude characteristics of the short-term pressure failure in the ventilation tube housing (VTH) while the engine is started and pressure changes in the VTH during steady air flow in engine. When determining the location of damage crankcase ventilation systems carry an indication, the first or second end is damaged. Install another diagnostic code on the basis of determining at a first end and a second end of VTH is damaged. Send the message to indicate to the user of the vehicle on the location of housing system damage. Take a soothing effect, including the adjustment parameters of the engine, the engine power limit in response to said specific location. Engine operation method version and engine system are disclosed.

EFFECT: simplification of the integrity control system crankcase ventilation system.
