A SURGE CONTROLLING METHOD FOR TURBO CHARGER ON DIESEL ENGINE

摘要

In a diesel engine equipped with a turbocharger, when the tip of the accelerator pedal is tipped out, the difference between the intake pressure supercharged in the combustion chamber and the exhaust pressure in the combustion chamber is detected. To prevent the occurrence of surge,;The process of detecting the displacement of the accelerator pedal and the intake pressure supercharged into the combustion chamber by the turbocharger and the exhaust pressure of the combustion chamber, determining whether the tip-out of the accelerator pedal is detected, and the tip-out of the accelerator pedal are detected. And determining whether the intake pressure to the combustion chamber and the exhaust pressure deviation in the combustion chamber are detected, and if the deviation is detected, applying the duty value set as a function of the differential pressure to control the EGR valve.
