METHOD TO CONTROL AIRFLOW IN INTERNAL COMBUSTION ENGINES, DEVICE TO THIS END, INTERNAL COMBUSTION ENGINE OPERATED BY SAID METHOD AND INTERNAL COMBUSTION ENGINE COMPRISING SAID DEVICE

摘要

FIELD: engines and pumps. ^ SUBSTANCE: proposed method comprises direct injection of fuel using at least one intake and discharge element in every cylinder and consists in the following, i.e. determining signal () of accelerator pedal that depends upon the position of said pedal and determining signal (n) of rpm depending upon engine rpm. It comprises also determining the magnitude of load spectrum proceeding from aforesaid signals () and (n), time (tLi) depending upon said spectrum and describing the period during which the gas escape orifice in each cylinder is open in compression stroke and amount (~ti) of fuel injected in each cylinder during one working stroke and depending upon load spectrum. Note also that ignition dwell angle subject to load spectrum is determined. Proposed invention covers also the device implementing proposed method. ^ EFFECT: reduced emission of harmful gases. ^ 24 cl, 3 dwg
