CONTROL OVER AUTOMOTIVE ENGINE AUTOMATIC OUTAGE Russian patent published in 2014 - IPC F02N11/08 

Abstract RU 2522948 C2

FIELD: engines and pumps.

SUBSTANCE: invention relates to ICEs. Proposed method comprises the steps that follow. (a) Magnitude defining the temperature (Tavt) of exhaust gases circulating at engine exhaust pipe, at turbocompressor turbine inlet. (b) Said magnitude is compared with preset threshold magnitude (Tavt_seuil). (c) In case the former magnitude is larger than the latter, first time delay (Tempo-in) is activated to repeat steps (a) and (b). If, during said time delay, the former is smaller than the latter, said time delay is stopped to initiate step (d). (d) In case the former magnitude is larger than the latter, second time delay (Tempo-out) is activated to repeat steps (a) and (b). If, during said time delay, the former is smaller than the latter, said time delay is stopped. Process of the second time delay is initiated again to initiate step (c). (e) In case first delay elapses and the former magnitude exceeds said threshold magnitude, engine automatic outage is prohibited. (f) In case second time delay elapses and the former magnitude is smaller than threshold magnitude, engine automatic outage is permitted to initiate, again, the first time delay.

EFFECT: limited increase in turbocompressor temperature at automatic engine outages.
