Claims

[Claims for Utility Model Registration] A device for improving the torque and smoke characteristics of a diesel engine, which is provided in a turbocharger mounted on the engine and in a fresh air pipe between the turbocharger and the engine. and a self-regulating discharge valve 14, the turbocharger corresponding to the fresh air consumption at full load of the engine when the engine speed is at or near half the rated speed. of fresh air, and at this speed a pressure ratio is observed which is limited by the maximum permissible combustion pressure, and when the engine speed is at the rated speed, the fresh air consumption at full load is observed. and the self-regulating discharge valve automatically adjusts the pressure to adjust the discharge pressure to the maximum allowable excess supply pressure. A device that improves the torque and smoke characteristics of diesel engines.
