Beschreibung
Zusammenfassung:	Disclosed is a high-low pressure EGR exhaust gas management system for a natural gas engine, which is characterized in that said system comprises: an engine, an exhaust manifold, a turbocharger, an EGR cooler, an EGR throttle valve, a cooler, a water removal device, an intercooler, and a throttle; the exhaust manifold is connected to the engine; the turbocharger is connected to the exhaust manifold; the EGR cooler is connected to the exhaust manifold; the EGR throttle valve is connected to the EGR cooler; the cooler is connected to the EGR throttle valve; the water removal device is connected to the cooler and the turbocharger; the intercooler is connected to the turbocharger; and the throttle is connected to the intercooler and the engine. The present invention solves the problem where a large volume of moisture-containing high temperature high pressure EGR exhaust gas of a current EGR exhaust gas management system enters into a compressor, causing the pressurization efficiency of a gas pressurizing end of a
