MODE OF OPERATION AT DEPLETED MIXTURES AT IDLE TO REDUCE AMOUNT OF SOLID PARTICLES Russian patent published in 2019 - IPC F02D41/00 

FIELD: machine building.

SUBSTANCE: invention relates internal combustion engines operation control. Result is achieved by the fact that internal combustion engine, which can be operated in operation mode on lean mixtures and in stoichiometric mode, contains: engine casing (1), at least one combustion chamber (4) and preferably one throttle device (11), through which supercharging air from the supercharging air cooler can be supplied to combustion chamber (4), at which the internal combustion engine at idle stroke switches to the operation mode on the lean mixtures and is operated in the mode of operation on the lean mixtures, so that, in particular, the pressure drop between engine casing (1) and combustion chamber (4) is reduced.

EFFECT: technical result is reduction of amount of ejected solid particles.
