FIELD: mechanical engineering; internal combustion engines. SUBSTANCE: proposed method of operation of internal combustion engine during its heating period includes control at least over one working parameter of engine as a function of at least definite value of energy supplied to engine from moment of beginning of its heating for provision of higher stability of combustion in process of heating. Amount of energy supplied to engine should be preferable based on amount of fuel getting into engine in process of heating. EFFECT: provision of stable combustion in process of heating. 11 cl, 7 dwg
