Responsive: Optimal exhaust gas flow adaptation for all engine temperatures and driving conditions.
Precision: Integrated position sensor allows more accurate control of exhaust gases, resulting in a higher level of precision.
Durability: Reduction in the effect of exhaust pressure and exhaust flow provides carbon corrosion resistance and longer life.
Emission Reduction: Reduced NOx emissions.
The vacuum type consists of an EGR valve. The pressure inside the diaphragm chamber of the EGR valve is changed to adjust the valve opening.
DC MOTOR TYPE
The EGR valve is driven by the DC motor. The motor speed is reduced by a gear and the valve connected to the valve shaft is rotated, adjusting the area of the EGR passage.
The valve opening is detected by the angle sensor, which uses a Hall element, and sent to the ECU as feedback.
