Engine exhaust gas pressure control system

For turbocharged diesel engines, exhaust pressure is decisive part of the engine affecting the torque production in diesel engine. Turbo do not need any extra power for its own functioning. The exhaust gases which are coming out from the engine are not with constant pressure. Due to which the turbo cannot compress the air in proper ratio. This paper shows the outcome of total practical experiment to control the exhaust gases. These control and constant gasses automatically controls the turbine to run at the constant speed, so that the engine can get proper compressed ratio of air and diesel.
