METHOD FOR START OF INTERNAL COMBUSTION ENGINE WITH EXIT GAS NEUTRALISATION UNIT Russian patent published in 2013 - IPC F02D41/02 F02D41/06 

FIELD: engines and pumps.

SUBSTANCE: this method in combination with cold start and/or warming-up at an idle operation of internal combustion engine (1) is used to start engine (1) by means of a cold start mode with preset values of engine operating parameters; quantity of accumulated one or several hydrocarbons in at least one component of exit gas neutralisation is estimated and the cold start mode of a motor is activated, if according to estimation quantity of peaks of HC-desorption stipulated by combustion gases of filler exceeds preset limit value.

EFFECT: method provides possibility of heating of components of exit gas neutralisation and allows defining exact time of engine warming-up with possibility to stop an active mode of the motor cold start, thus allowing to avoid fuel overflow or at least to restrict it.
