Abstract

The invention discloses a circulating air intake system for an engine. The circulating air intake system comprises a turbocharger compressor casing and an EGR mixer; the EGR mixer comprises a mixer outer shell, and an external air duct and a circulating exhaust gas duct in the mixer outer shell; the circulating air intake system further comprises a regulating valve for regulating a diameter of the external air duct; the regulating valve is arranged within the mixer outer shell and mechanically connected with a control executor; the control executor comprises an execution response device and an air control device of which one end communicates with the turbocharger compressor casing. A pressure of external incoming air in the turbocharger compressor casing is sensed through the air control device; the air control device originates a control action and a mechanical motion is generated through the execution response device; and the motion is transmitted to the regulating valve to regulate an external air pressure in the external air duct, so that a difference between the external air pressure and a pressure of circulating exhaust gas going into the mixer outer shell is kept within an ideal value, and therefore, an exhaust gas circulating system of the engine is kept efficient in working under different working conditions.

Description

technical field [0001] The invention relates to the technical field of the automobile industry, and more specifically relates to a circulating air intake system for an engine. Background technique [0002] As China's emission regulations become increasingly stringent, engines, especially diesel engines, must greatly reduce the emission of NOx, the main emission. At present, EGR technology is one of the effective means to reduce NOx emission of diesel engine recognized internationally. EGR is more and more applied to the engine. The full name of EGR is ExhaustGasRecirculation, which means that part of the exhaust gas discharged from the engine is returned to the intake manifold, and mixed with fresh air to enter the cylinder again, thereby reducing the generation of NOx. [0003] NOx is a gas that is extremely harmful to the human body. It is mainly produced under the condition of high temperature and rich oxygen. The higher the combustion temperature and oxygen concentratio...
