EGR SYSTEM
EGR Valve Control
The EGR (exhaust gas recirculation) system consists of a direct current EGR volume control valve fitted with a
EGR volume control valve control position sensor. The EGR volume control valve is controlled in a closed-loop
via the EGR volume control valve control position sensor. Up to a certain rate, exhaust gas recirculation
enables nitrogen oxide (NOx) emissions to be reduced significantly.
Measurement of the Fresh Air Flow
The flow of fresh air entering the engine is calculated by a mass air flow sensor (ratiometric hot-wire sensor).
An intake air temperature sensor is integrated into the mass air flow sensor.
The mass air flow sensor facilitates control of the quantity of exhaust gas sent for recirculation, thus ensuring
the best possible recirculation rates. Air flow measurement allows closed-loop control via the EGR valve.

IDLE SPEED CONTROL
System DiagramINFOID:0000000001162537
System DescriptionINFOID:0000000001162538
The ECM is responsible for regulating the idle speed as a function of the idle speed setpoint which it calcu-
lates.
 The idle speed setpoint is dependent on:
- Engine coolant temperature
- Emission control program
- Air conditioning requirement
- Gear engaged
- Electrical load
- Battery voltage
1. Engine speed in rpm 2. Engine coolant temperature °C
