Abstract:
1. A dual path fresh air system, comprising: a first air supply path, wherein the first path supplies air to at least one first cylinder set; a second air supply path, wherein the second path supplies air to at least one second cylinder set; a first exhaust gas recirculation inlet fluidly connected to the first path to introduce recirculated exhaust gas into the first path; a second exhaust gas recirculation inlet fluidly connected to the second path to introduce recirculated exhaust gas into the second path; a first valve member, which is arranged upstream of the first exhaust gas recirculation inlet in the first path, wherein the first valve member controls fluid flowing through a cross section of the first path; a second valve member which is arranged upstream of the second exhaust gas recirculation inlet in the second path, wherein the second valve member controls fluid flowing through a cross section of the second path; and a valve device, which comprises the first valve member, the second valve member and a common drive member for the two valve members, wherein the two valve members are coupled in a phase-offset manner to the drive member such that one valve member at least one of minimizes and blocks the cross section through which fluid flows of one path whereas at the same time the other valve member at least one of maximizes and opens the cross section through which fluid flows of the other path, and vice versa.
