FIELD: mechanical engineering; internal combustion engines. ^ SUBSTANCE: proposed internal combustion piston engine contains two, four and more cylinders with pistons combined by crankshaft, and starting, ignition and valve timing systems with gang of spark plugs or nozzles, intake and exhaust valves, and carburetor. To provide isobaric heat removal to low-temperature source engine is furnished with manifold communicating through intake valves with cylinders and through shutoff member with carburetor. Sequence of operation of intake valves and shutoff member is provided by camshaft at corresponding position of piston in one of three specific points with due account of length of piston stroke in process of compression and expansion. ^ EFFECT: increased thermal efficiency, reduced noise level, cut down discharge of harmful substances with exhaust gases, improved organization of working cycle. ^ 1 tbl, 6 dwg |
