Multi-pipeline crossing mutual control device

Abstract

The invention provides a multi-pipeline crossing mutual control device. The multi-pipeline crossing mutual control device comprises a gas compressor, an engine, a turbine, a connecting pipe, a valve seat, a valve body, a rotating shaft, a receiving chamber, a stator, a penetrating pipe, a separator, a rotator and a connecting plate; one end of the rotator extends into the first penetrating pipe and is in sealing contact with the wall of the first penetrating pipe, while the other end of the rotator is fixedly connected with the separator; one end of the second connecting pipe is communicated with the intake pipe of the engine, while the other end of the second connecting pipe is communicated with the first penetrating pipe after penetrating through the stator. When the front and back pressure difference of the gas compressor is relatively high, the rotator drives a butterfly valve to rotate clockwise, and the exhaust gas recirculation rate of the engine is relatively high, while the detonation pressure of the engine is relatively low. The multi-pipeline crossing mutual control device is reasonable in design, simple in structure, and suitable for the exhaust gas recirculation system of a supercharged 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 multi-pipeline crossing mutual control 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 ...
