METHOD FOR SUPERCHARGED ENGINE Russian patent published in 2019 - IPC F02D9/10 F02D41/22 

FIELD: internal combustion engines.

SUBSTANCE: invention can be used in internal combustion engines with supercharging and throttle located downstream of the compressor and the supercharging air cooler in the engine intake system. Method for a supercharged engine comprises the fact that in the first state, when the accelerator pedal is not engaged, in connection with detecting the first clogging of the throttle, first voltage is supplied in first direction to throttle motor connected with throttle to set throttle movement to fully open position. Then the second voltage is supplied in the second, opposite direction to the throttle motor to set the throttle movement to the fully closed position. In the second state, due to detection of the second throttle clogging, the third voltage is supplied in the first direction to the throttle motor to set the throttle movement to the fully open position regardless of the accelerator pedal position. Third voltage is maintained during the threshold period for holding the throttle in the fully open position during the threshold period. Then the fourth voltage is supplied to the throttle motor in the second direction to set the throttle movement to the required position, at the same time the required position depends on the current position of the accelerator pedal.

EFFECT: technical result consists in improvement of removal of ice particles settled on throttle during engine start-up after vehicle idle in cold conditions, in particular, in elimination of free-ice chocking by throttle.
