Abstract

The invention relates to a system and a method for correcting turbo lack and a vehicle. The system for correcting turbo lag of a diesel engine vehicle equipped with a turbo charger and a vacuum pump according to the present disclosure may include: a chamber being supplied with an air / oil mixture discharged from the vacuum pump, separating and storing the mixture into air and oil, and including a first valve for spraying the air and a second valve for discharging the oil; an accelerator pedal sensor sensing a depression extent of an accelerator pedal of the vehicle; a first pressure sensor sensing the pressure of the air compressed in the chamber; and a controller controlling the first valve in accordance with the depression extent of the accelerator pedal sensed by the accelerator pedal sensor.

Description

technical field [0001] The present disclosure relates to a system for correcting turbo lag. Background technique [0002] Most diesel engine vehicles are equipped with a turbocharger. A turbocharger system is a system that increases the amount of air to be drawn into the intake manifold using a turbocharger connected to the intake and exhaust manifolds. In detail, a turbine of the turbocharger is forced to rotate by exhaust gas flowing through an exhaust manifold, a compressor connected to the turbine operates, whereby air is forcibly drawn into an intake manifold. In other words, according to the turbocharger system, high-temperature and high-pressure exhaust gas changes to low-temperature and low-pressure exhaust gas while passing through the turbine, so the energy of the exhaust gas is transferred to the turbine, thereby rotating the turbine. [0003] Meanwhile, turbo lag inevitably occurs in a vehicle equipped with a turbocharger system. Turbo lag refers to a phenomen...
