METHOD OF DETERMINING FUEL EVAPORABILITY AND ICE COLD STARTING Russian patent published in 2010 - IPC F02D41/06 

FIELD: engines and pumps.

SUBSTANCE: proposed method consists in that enrichment percentage (%_Enrich) is determined in ICE cold start as the function of memorised fuel evaporability (V_mem) and engine is started using predetermined enrichment percentage (%_Enrich). Additionally, forecast start quality (Mark_Pred) is determined prior to starting the engine. Measured start quality (Mark_Meas) is determined during initial increase in engine rpm. Correction (V_corr) for memorised fuel evaporability (V_mem) is determined as the function of comparison between measured start quality (Mark_Meas) and forecast start quality (Mark_Pred) for memorised fuel evaporability (V_mem) to be edited by using correction (V_corr) for memorised fuel evaporability (V_mem).

EFFECT: method of determining fuel evaporability and ICE cold starting.
