At the intake manifold of plastics, generally adopt independently EGR off-gas circuit.The EGR valve directly be connected on the cylinder cap or by one independently conversion adapter be connected with EGR waste gas outlet on the cylinder cap, the while externally the arranging EGR pipeline be connected with intake manifold.This arrangement has satisfied the light-weighted requirement of motor, but integral arrangement is not as the former compactness.

No matter be to adopt cast aluminium intake manifold or employing plastic air intake manifold, cooling liquid outlet passage on the motor and EGR waste gas outlet passage all are separately independently at present, on motor, need a water outlet bearing (only antifreeze liquid passage), a water outlet bearing pad, an EGR exhaust stand (only directly make on cylinder cap as if the EGR valve seat by exhaust steam passage, then do not need), EGR valve gasket and associated components are finished the circulation of two kinds of fluids.

The common drawback of this class formation is:

1. because the outlet of two kinds of fluid passages is separately independently, can not effectively utilize cooling liquid that EGR waste gas is cooled off, reduce intake temperature;

2. because the outlet of two fluid passages is separately independently, cause on the motor spatial arrangement compactly inadequately, can not effectively utilize the space of engine compartment;

3. because need two pedestals to be used as the outlet of two kinds of fluids respectively, cause the motor purchase cost to increase.
