Abstract

The invention discloses a self-adjusting exhaust gas recycling system, belonging to the technical field of combustion engines. The self-adjusting exhaust gas recycling system comprises an air inlet pipe, an engine, an exhaust pipe, a compressor, a turbine, a connecting pipe, a volume chamber, a movable body and an elastic component, wherein the cross section of the volume chamber is of a rectangular shape; the movable body is arranged inside the volume chamber and is tightly contacted with the inner wall surface of the volume chamber; the movable body is connected with the upper wall surface of the volume chamber through the elastic component; when the engine is in a high-speed work condition, the movable body moves upwards in the volume chamber, the exhaust gas recycling rate is larger, the exhaust temperature is lower, and the overall performance of the engine is more excellent; when the engine is in a low-speed work condition, the movable body moves downwards in the volume chamber, the exhaust gas recycling rate is smaller, the air inlet quantity is larger, and the overall performance of the engine is more excellent. The self-adjusting exhaust gas recycling system is reasonable in design, simple in structure and suitable for the exhaust gas recycling system with a turbosupercharger.

Description

technical field [0001] The invention relates to an exhaust gas recirculation system in the field of internal combustion engines, in particular to a self-regulating exhaust gas recirculation system 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 small part of th...
