FIELD: machine building.
SUBSTANCE: exhaust device consists of cylinder case with inlet branch and outlet orifice, of swirler with blades and of fairing in form of truncated cone. The swirler is also made in form of a truncated cone positioned with its base to the inlet branch. The blades of the swirler are inclined at 45 degrees to the case of the device. The swirler and fairing are directed with their truncated vertexes one towards another; also, the fairing is positioned with its base to the outlet orifice and is equipped with a diffusing grid, thus controlling volume of air coming from environment to the case of the device.
EFFECT: reduced fuel rate at maintaining power and torque of engine; reduction of harmful exhausts.
