Exhaust gas recirculation for a diesel engine |
摘要 |
An exhaust gas recirculation control valve for a diesel engine. The valve comprises a valve casing of a rectangular cross-sectional shape disposed in the intake line of the engine. A valve seat connected to an exhaust line of the engine via an EGR passageway is formed in a side wall of the rectangular-shaped valve casing. A valve member is arranged in the casing and then rotated about an axis located upstream of the valve seat in such a manner that the valve member is moved between a position wherein valve member closes the valve seat and another position wherein the plate closes the intake passageway. The valve member comprises a base portion of a flat shape and a guide portion which is inserted into the valve seat when the degree of opening of the valve member is small.
