mechanical engineering; internal combustion engines. SUBSTANCE: proposed method relates to operation of internal combustion engine with independent constant-volume combustion chamber in which compression chamber and expansion chamber for each cylinder or each working element of combustion chamber are made as three separate and completely independent elements. Compression chamber cycle leads expansion chamber cycle to provide considerable increase of burning time. Compressed fuel mixture gets into combustion chamber after opening of valve closing the channel which connects compression chamber with expansion chamber. As soon as valve gets closed, burning takes place in independent insulated constant-volume chamber for a considerable times. When volume of expansion chamber reduces to minimum value, valve installed in channel connecting combustion chamber and expansion chamber opens, and high-pressure gases expand, thus pushing the piston and executing working stroke. EFFECT: increased time of burning and displacement of gases, improved operation of engine. 5 cl, 9 dwg |
