FIELD: engines and pumps.SUBSTANCE: proposed method is intended for engine equipped with air intake system 2 including intake pipe 4 and valves 6 to control flow rate of air fed into pipe 4. Proposed method comprises realisation of first algorithm based on Sen-Venan model and second algorithm based on "filling-emptying" model for definition of first (MAF_SV) and second (MAF_FF) magnitudes of air flow rate at inlet of said pipe. It comprises also selecting first airflow rate (MAF_SV) in case relationship (?) between pressures (p, p) at inlet and outlet of said valves are lower than preset threshold magnitude ?varying from 0.9 to 0.95, and selecting second airflow rate (MAF_FE) in case said relationship (?) between pressures (p, p) at inlet and outlet of said valves are higher than said threshold ?. Invention covers also ICE implementing above described method.EFFECT: higher accuracy of air flow rate measurement.10 cl, 2 dwg |
