FIELD: engines.
SUBSTANCE: invention relates to engine technology. A non-compression engine comprises two or three variable volume mechanisms: a device 1 for intake and displacement and a device 2 for combustion and expansion, or a device 1 for intake and displacement, a device 2 for combustion and expansion and an atmospheric cooler 3. Working gas volume drawn into device 1, and then displaced into device 2 at a substantially constant volume, passes through a regenerator 5. Gas in device 2 is further heated by fuel combustion and then expanded to produce work. Gas then moves through regenerator 5 into atmospheric cooler 3 at a substantially constant volume or exits regenerator at constant pressure. Gas volume decreases in atmospheric cooler while performing atmospheric work. After equilibration of gas pressure with atmospheric pressure, said gas is released from atmospheric cooler 3.
EFFECT: technical result is high efficiency.
