Abstract

FIELD: engine engineering. SUBSTANCE: device has housing with a flow passageway provided with the cylindrical part connected with the converging outlet part through a converting section, inlet air passageways made in the housing, throttle gate, and means for supplying fuel. The air passageway are tangent to the cylindrical part of the flow passageway. The throttle is movable with respect to the housing and is mounted to permit cutting off the flow sections of the inlet air passageways. The means for supplying fuel has outlet fuel passageway that is tangentially connected with the flow passageway. In addition, the device is provided with a belt twisted spring, base of the spring, second throttle gate, and plate valve. The second throttle gate is movably mounted at the inlet of the cylindrical part of the flow passageway. The rib of the belt twisted spring abuts against the wall of the flow passageway. The middle turn of the spring is rigidly secured to the base that is rigidly secured to the housing. The top turns of the spring are flexibly connected with the second throttle gate. The bottom turns of the spring are flexibly connected with the plate valve mounted at the outlet part of the flow passageway. The means for supplying fuel is at the inlet cylindrical part of the flow passageway. The flexibility of the ends of the belt twisted spring is less than the flexibility of the central part as much as by a factor of 2-2.5. There are additional radial inlet air passageways. EFFECT: decreased toxicity of exhaust.
