MANAGEMENT DEVICE FOR INTERNAL COMBUSTION ENGINE, EMISSIONING EMISSIONS OF WHITE SMOKE Russian patent published in 2018 - IPC F01N3/10 F01N9/00 F02D11/10 F02D41/14 

FIELD: engines and pumps.

SUBSTANCE: control device for the internal combustion engine includes an exhaust gas control device in the exhaust system of the internal combustion engine. The exhaust gas control device comprises an intake air volume regulator, a temperature sensor and an electronic control unit. The temperature sensor has the ability to measure the temperature of the exhaust gas control unit. The electronic control unit has the ability to estimate the amount of sulfur compound accumulation. The value of sulfur compound accumulation is the amount of sulfur compound accumulated on the exhaust gas control device. When a specific condition in which the value of the accumulation of sulfur compounds is equal to or above a predefined magnitude accumulation (S1) and the temperature of control device with exhaust gases is equal to or above the predefined temperature (S2) is satisfied in operational state, the electronic control unit manages the intake air volume regulator so that the intake air volume controller increases volume of suction air (S5) compared with, when a particular condition is not satisfied in the same operational state (S4).

EFFECT: more accurate determination of the amount of sulfur compound accumulation.
