FIELD: mechanical engineering; internal combustion engines.
SUBSTANCE: proposed engine has working cylinder with ring working chamber and inflow scavenging, piston chargers with eccentric drive, and shaft with central crank and side eccentrics. Diametric boss is made on crowns of charging pistons which is in contact with cylinder face, and cavity is made in heads of chargers to form, respectively, three successively communicating chamber in each charger with separate delivery of parts of fuel charge at intake for delivering stratified fuel charge through scavenging channels into working chambers. Lean mixture gets into farther chamber, and clean air, into near chamber.
EFFECT: improved efficiency of operation of engine owing to better organization of working process.
