FIELD: engines and pumps.
SUBSTANCE: two-stroke engine consists of three power units with a common for all blocks of the external combustion chamber and a common pneumatic accumulator with a start-up valve. Each power unit includes a cylinder with a power piston and an intake valve, a cylinder with a compressor piston and check valves and a crankshaft. The crankshaft of the power piston is deployed in relation to the crankshaft of the piston of the compressor piston for a half-turn. Three power units are combined in a tandem in such a way that the geometric axes of their crankshafts are located on the same geometric axis. In turn, the crankshaft of each power unit is deployed relative to the other power block by one-third of the turnaround. General pneumatic accumulator and trigger valve is connected to another network through a non-return valves all power blocs, and the products of combustion of common external combustion chamber is connected by a channel with inlet valves all power blocs.
EFFECT: increased engine efficiency.
