Abstract

An exhaust recirculating system controlled by the aid of air inlet pressure relates to the technical field of internal combustion engines and comprises an air inlet tube, an engine, an exhaust tube, a compressor, a turbine, connecting tubes, a volumetric cavity, a mover and an elastic component. A third connecting tube is mounted between an air inlet main tube and an upper wall surface of the volumetric cavity, the cross section of the volumetric cavity is rectangular, the mover is mounted in the volumetric cavity and hermetically contacts with an inner wall surface of the volumetric cavity, and the mover is connected with a lower wall surface of the volumetric cavity via the elastic component. When the engine is in a middle-speed working condition, the mover upwards moves in the volumetric cavity, exhaust recirculating rate is high, exhaust temperature is low, and performances of the total engine are excellent; and when the engine is in a high-speed working condition, the mover downwards moves in the volumetric cavity, exhaust recirculating rate is low, dynamic property of the engine is good, and performances of the total engine are excellent. The exhaust recirculating system is reasonable in design and simple in structure. The invention is applicable to exhaust recirculating systems with turbochargers.

Description

technical field [0001] The invention relates to an exhaust gas recirculation system in the field of internal combustion engines, in particular to an exhaust gas recirculation system controlled by intake pressure with a turbocharger. 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 s...
