FIELD: engine building.
SUBSTANCE: invention can be used in the internal combustion engines. Device (V) for creation of negative pressure in crankcase (1) of engine and/or for removal of air from crankcase of engine comprises crankcase (1) of engine, combustion chamber (4), oil separator (16) connected to engine casing and pressure adjusting device (17). Pressure adjustment device is made with possibility of setting in operating mode of negative pressure in crankcase (1) of engine for targeted reduction of pressure difference between engine casing and combustion chamber. Engine crankcase via guide device (X) at connection point (A) is connected to supercharging air feed pipeline (21) for feeding supercharging air into combustion chamber. Guide device (X) comprises control device (15). Control means is configured to limit the vacuum in the engine crankcase by such operating modes as idling, weak load and/or forced idle running of the engine. Device (V) comprises pressure determining device (23) for measuring pressure in engine crankcase. Pressure adjusting device is made with possibility of negative pressure setting from 0.1 to 500 mbar in engine crankcase. Operating method of the device, an internal combustion engine and trackless vehicle are described.
EFFECT: technical result is to reduce the number of ejected particles.
