The function of LP EGR is to re-circulate the exhaust gases after DPF (Diesel Particulate Filter) to further improve ability to meet the emission level as well as reducing the CO2 thereby improving the fuel economy. It also improves engine transient performance due to more exhaust energy being diverted to the turbocharger(s).
As per HP EGR the function is electronically controlled and calibrated. It is governed and controlled by both hot end exhaust mounted throttle as well as unit mounted valve.
