INTERNAL COMBUSTION ENGINE CONTROL DEVICE Russian patent published in 2017 - IPC F02D41/06 

FIELD: engines and pumps.

SUBSTANCE: device contains a regulator which regulates the volumetric flow rate of the exhaust gases exhausted from the engine per unit time; as well as a controller. If the outside temperature sensor detects that the outside temperature is below the freezing point and the previous period of the engine operation is shorter than the predetermined first time period, the controller controls the regulator so that the mentioned volumetric flow rate of the exhaust gases increases, exceeding the predetermined level for the normal mode, until the second predetermined time period runs out after the engine starts.

EFFECT: increased volumetric flow rate of exhaust gases per unit time to ensure the drainage of condensate and the melting of ice inside the exhaust pipe.
