Abstract:
An exhaust gas recirculation (EGR) system is provided. The EGR system includes an engine having an intake manifold. The intake manifold is adapted to receive intake air from an aftercooler. The EGR system also includes an exhaust manifold. The exhaust manifold is adapted to receive exhaust gas from a plurality of cylinders of the engine. The EGR system further includes an EGR line. The EGR line is fluidly coupled between the intake manifold and the exhaust manifold. The EGR system includes an EGR valve disposed in the EGR line. The EGR system also includes a pressure line. The pressure line is coupled between the intake manifold and the EGR valve. The EGR valve is movable to an open position from a closed position, based on an intake pressure communicated to the EGR valve via the pressure line.
