Abstract
A diesel engine system includes a diesel engine, a NOx control device downstream of the engine, an exhaust line between the engine and the NOx control device, a bypass line connected to the exhaust line at a first end upstream of the NOx control device, and a bypass valve connecting the exhaust line and the bypass line, the bypass valve permitting flow through the exhaust line to the NOx control device when in an open position and preventing flow through the exhaust line to the NOx control device and permitting flow through the exhaust line to the bypass line when in a closed position. A controller can arranged to control opening and dosing of the bypass valve, such as when an operating condition of the engine reaches a predetermined operating condition.
