CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE Russian patent published in 2018 - IPC F01N3/25 F01N9/00 F02D41/08 

FIELD: engines and pumps.

SUBSTANCE: internal combustion engine includes an exhaust gas monitoring device disposed in the exhaust passage of the internal combustion engine and a fuel supply device configured to supply fuel to the exhaust gas monitoring device. The control device contains an electronic control unit. Electronic control unit with control of the fuel supply fuel supply device for regeneration control in such a way that the temperature of the exhaust gas control devices rises and particulates, besieged at exhaust control device burn out. The electronic control unit provides the temperature increase exhaust control devices the first-speed increase in temperature for regeneration control when the temperature of the exhaust gas control devices is in the first temperature range. The electronic control unit provides an increase in the temperature of the exhaust gas monitoring device with a second rate of temperature increase as regeneration control when the temperature of the exhaust gas monitoring device is in the second temperature range. The second rate of temperature rise is lower than the first temperature increase rate, and the second temperature range is higher than the first temperature range. The electronic control unit provides the conditions for burning solid particles by maintaining the temperature of the exhaust gas monitoring device in the third temperature range as regeneration control when the temperature of the exhaust gas monitoring device is in the third temperature range. The third temperature range is higher than the second temperature range. The electronic control unit provides control of temperature control devices, exhaust gas at idle mode of operation so that it is equal to or less than the temperature of the exhaust gas control devices at a time when the engine internal combustion engine is included in the status of idling operation mode to manage the prevention of temperature increase when the temperature of the emission control devices during the regeneration control is the second temperature range and internal combustion engine is in idle state.

EFFECT: preventing the formation of white smoke when the engine is idle.
