Venturi Tube - Detroit Diesel Series 60 EGR Technician Manual

DDEC V COMPONENTS

Venturi Tube

The venturi tube with a port at each end is located in the EGR delivery pipe which is connected to
the EGR cooler outlet. The Venturi tube ports are connected to the Delta P Sensor to monitor the
pressure differential across the venturi as EGR exhaust gases flow through the EGR delivery pipe
to the charge air mixer. DDEC V uses this information along with temperature and density of
the exhaust gases to determine precise EGR Mass Flow Rate.
