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 discharged from the combustion chamber, determining whether the tip-out of the accelerator pedal is detected, and the tip-out of the accelerator pedal Is detected, a process for determining whether a deviation is detected between the intake pressure into the combustion chamber and the exhaust pressure discharged from the combustion chamber, and if a deviation between the pressures is detected while the intake pressure is higher than the exhaust pressure, the duty value determined as a function of the differential pressure. The control of the EGR valve may include the step of quickly discharging the intake pressure in the turbocharger compressor to the exhaust side maintaining a relatively low pressure, so that no surge is generated.
