Fox egr valve accelerates to open normally.

The normal opening of Fox egr valve will be accelerated by 50%~80%.

Exhaust gas recycling (EGR for short) is a technology that introduces a part of exhaust gas from small internal combustion engines of automobiles into the intake side for re-intake. The purpose is to reduce nitrogen oxides in exhaust gas and improve fuel economy under partial load, so 50%~80% opening data is considered normal.

The Fox EGR valve is in the cylinder block, behind cylinder 4 or on the crankcase. The EGR valve is usually located on the right side of the intake manifold, close to the throttle body and connected with the intake manifold and the exhaust manifold.
