METHOD OF OPERATING TWO-STROKE INTERNAL COMBUSTION ENGINE Russian patent published in 1995 - IPC

FIELD: engine engineering. SUBSTANCE: working charge is fed to the working cylinder, cooling charge is fed to the space heated by combustion products of working charge, working charge is compressed in the cylinder, cooling charge is compressed and heated in the space, working charge is ignited and burnt out, combustion products is expanded in the cylinder to do mechanical work, exhaust gases are discharged from the cylinder and heated cooling charge is by-passed from the space to the cylinder for its blowing. The heated cooling charge is expanded before by-passing to the cylinder with further heating and doing additional mechanical work. EFFECT: enhanced efficiency. 2 dwg
