Description and Operation

2.3L Duratec-HE (MI4)

Apart from a few changes, the 2.3L Duratec-HE (MI4) engine is largely based on the 2.0L
Duratec-HE engine already used in the S-MAX/Galaxy 2006.5 (03/2006-).

Key features of the engine include:

Direct ignition coils
Electronic throttle valve
Mechanical thermostat
variable Manifold Runner Control
Dual-mass flywheel
High-performance oil pump

Differences from the 2.0L Duratec-HE (MI4) engine variant fitted to the S-
MAX/Galaxy 2006.5 (03/2006-) MI4) are:

Variable camshaft timing (VCT)
Integral dipstick
Balance shafts

Variable camshaft timing (VCT)

Description

Control unit - variable camshaft timing

Camshaft bearing cap

VCT oil control solenoid

Valve cover

Camshaft Position Sensor

Camshaft sensor ring

This system is an electronically controlled camshaft adjuster that allows variable timing for
the inlet camshaft.

The valves are driven by a timing chain which drives the inlet camshaft timing control unit.
This unit drives the associated camshafts. The timing chain is tensioned using a
conventional timing chain tensioner.

The inlet camshaft is fitted with a sensor ring for the active camshaft position (CMP) sensor.

This CMP sensor is mounted inside the valve cover.

Timing chain replacement does not require the variable camshaft timing control unit to be
disconnected.

To ensure trouble-free operation of the variable camshaft timing system and optimum
engine performance, it is essential to adhere precisely to the valve timing adjustment
procedure.

A special tool is needed to fix the camshafts in the adjustment position.

Remember that this special tool must not be used to keep the camshaft from rotating when
mounting the camshaft sprocket. They may only be kept from rotating by using the
hexagon, which has been specially provided for this purpose.

Advantages of variable camshaft timing (VCT)

Lower fuel consumption due to improved volumetric efficiency
Enhanced engine power and torque
Improved idling characteristics
