Abstract

The invention relates to a high-pressure stage loop device using an exhaust gas as a gas source in the technical field of internal combustion engines. The high-pressure stage loop device comprises a gas inlet pipe, an engine, an exhaust pipe, a gas compressor, a turbine, a connecting pipe, a capacity cavity, a moving body and an elastic component, wherein the connecting pipe is communicated with the wall surface of the capacity cavity; the moving body is arranged in the capacity cavity and is in sealed contact with the inner wall surface of the capacity cavity; a through pipe penetrates through the left wall surface and the right wall surface of the moving body; and two ends of the elastic component are respectively connected with the upper wall surface of the moving body and the upper wall surface of the capacity cavity. When the engine is under a medium-low speed working condition, the moving body moves downwards in the capacity cavity, the exhaust recycling rate is large, the exhaust temperature of each cylinder of the engine is low, and the performance of the entire engine is excellent; and when the engine is under a high-speed working condition, the moving body moves upwards in the capacity cavity, the exhaust recycling rate is small, the dynamic property of the engine is good, and the performance of the entire engine is excellent. The high-pressure stage loop device is reasonable in design and simple in structure, and is suitable for an exhaust recycling system provided with a turbocharger.

Description

technical field [0001] The invention relates to an exhaust gas recirculation system in the field of internal combustion engines, in particular to a high-pressure stage circuit device with a turbocharger using exhaust gas as a gas source. 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 sen...
