Exhaust System - International VT 365 Service Manual

24
The EGR system is closed loop control, using EGR
position signals.
The EGR drive module receives the desired EGR
valve position from the ECM across the CAN 2
datalink to activate the EGR valve for exhaust gas
recirculation. The EGR drive module provides
feedback to the ECM on the valve position, interprets
the ECM command, and sends the command using
three pulse width modulated signals to the DC motor.

Exhaust System

The exhaust system includes the following:
• Exhaust valves
• Exhaust manifolds
• Turbocharger
Read all safety instructions in the "Safety Information" section of this manual before doing any procedures.
ENGINE SYSTEMS

The exhaust system removes exhaust gases from
the engine. Exhaust gases exit from exhaust ports,
through exhaust valves, and flow into the exhaust
manifolds. Expanding exhaust gases are directed
through the exhaust tubes. The right exhaust tube
directs some exhaust gases into the Exhaust Gas
Recirculation (EGR) cooler. Exhaust gases flowing
into the VGT drive the turbine wheel. Exhaust gases
exit the VGT and flow into the exhaust piping, through
the muffler and catalytic converter or CDPF, and out
the discharge pipe to the atmosphere.
