Abstract

The invention discloses a pneumatic type rotary body rotary device in the technical field of mechanical design. The pneumatic type rotary body rotary device comprises a gas compressor, an engine, a turbine, a connecting tube, a valve base, a valve body, a rotary shaft, an accommodating chamber, a fixed tube, a penetrating tube, an elastic part, a partition plate, a rotary body and a connecting plate, wherein one end of the rotary body extends into the first penetrating tube and is in sealing contact with the wall surface of the first penetrating tube; the other end of the rotary body is fixedly connected with the partition plate; one end of the second connecting tube is communicated with a gas inlet tube of the engine; the other end of the second connecting tube is communicated with the accommodating chamber. When the pressure of the gas inlet tube of the engine is relatively high, the rotary body drives a butterfly valve to clockwise rotate, so that the larger the gas-exhausting and re-circulating efficiency of the engine, the lower detonation pressure of the engine; when the pressure of the gas inlet tube of the engine is relatively low, the rotary body drives the butterfly valve to anticlockwise rotate, so that the smaller gas-exhausting and re-circulating efficiency of the engine, the lower the oil consumption of the engine. The pneumatic type rotary body rotary device is reasonable in design, simple in structure and suitable for a gas-exhausting and re-circulating system of a booster engine.

Description

technical field [0001] The invention relates to an exhaust gas recirculation system in the technical field of mechanical design, in particular to a pneumatic rotary device. Background technique [0002] Harmful emissions from engines are a major source of air pollution. With the increasing importance of environmental protection, the goal of reducing harmful emissions from engines has become an important direction for engine development in the world today. With the world's consumption of petroleum products increasing year by year, international oil prices remain high, and the economy of diesel vehicles is becoming more and more prominent, which makes diesel engines occupy an increasingly important position in vehicle power. Therefore, it is the primary task of diesel engine designers to carry out research on the control methods of harmful emissions from diesel engines. Exhaust gas recirculation system is to send a small part of the exhaust gas produced by the diesel engine b...
