Abstract
An exhaust gas recirculation (EGR) system in an engine system includes an intake passage, an exhaust passage, an EGR passage, a connecting passage and an exhaust gas regulating valve. The exhaust passage is provided with a catalyst and a muffler. The EGR passage is provided with a heat exchanger and an EGR valve. The connecting passage fluidly connects the exhaust passage and the EGR passage. The exhaust gas regulating valve is mounted at a merging portion defined between the exhaust passage and the connecting passage. Based on the opening degree of the exhaust gas regulating valve, the exhaust gas flow is adjustably regulated into recirculating flow into the EGR passage or flow through the exhaust passage. Based on the opening degree of the EGR valve, the recirculated exhaust gas in the EGR passage is adjustably regulated into recirculating flow into the intake passage or flow into the connecting passage after passing through the heat exchanger.
