SYSTEM EC-837 < SYSTEM DESCRIPTION > [R9M] C D E F G H I J K L M A EC N P O EGR SYSTEM : System Description INFOID:0000000010935564 DESCRIPTION EGR (Exhaust Gas Recirculation) system reduces NOx emissions and improves fuel efficiency by recirculat- LOW PRESSURE EGR SYSTEM The low pressure EGR system recirculates exhaust gasses in the downstream DPF (Diesel Particulate Filter) ° C (158 ° F) and intake air temperature is 20 ° C (68 ° F), the opening angle of the exhaust throttle valve is reduced and the low pressure EGR volume control valve angle is adjusted to control EGR for achieving an appropriate EGR rate. HIGH PRESSURE EGR SYSTEM High pressure EGR system recirculates exhaust gasses in the exhaust manifold to the intake manifold. ° C (86 ° F), the opening angle of the throttle valve is reduced and the high pressure EGR volume control valve angle is adjusted to control EGR COOLING SYSTEM The EGR cooler bypass is controlled by ON/OFF solenoid valve, connected to the vacuum circuit. Control is JSBIA2009GB |
