METHOD OF CONTROLLING PRE-HEATER OF VEHICLE ENGINE AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2024 - IPC F02N19/10 F01N13/08 

FIELD: machine building.

SUBSTANCE: invention relates to methods and devices for prestart preparation of an internal combustion engine (ICE) of a vehicle for start-up. Disclosed is ICE pre-heater 1 control device, comprising a heater boiler, consisting of heater control unit 2, fuel pump 10 and a liquid pump, an air pump, a fuel supply valve, fuel ignition device 9, sensor 4 of position of cover of exhaust pipe of pre-heater, sensor 5 of temperature of exhaust gases, sensor of heated liquid vapourisation, sensor of boiler housing overheating. Device can be equipped with a timer for start-up 3 and blocking 6 of the heater operation, as well as sensors 7, 8 for temperature of the heated liquid at the inlet and outlet of the boiler of the heater.

EFFECT: increased reliability of ICE start-up at temperature below +5 °C, prevention of emergency situations that can lead to vehicle failure, prevention of damages associated with operation of vehicle with depressurized exhaust pipeline of heater and ingress of water and dirt into heater from external environment.
