Electronically Mapped Cooling System – Self-Study Programme 222 PDF. This Self-Study Programme describes the design and function of this technical innovation.
The 1.6-litre 4-cylinder in-line engine (code APF) with a power output of 74 kW is the first engine in which the newly developed electronically mapped cooling system will be used.
Further engines are in preparation. Load-dependent temperature setpoint input, thermostatic control of coolant temperature and fan cut-in control are the special features of the new system.
The advantages of adapting the coolant temperature to the current operating state are:
- reater fuel economy in the part-throttle range
- reduction of raw CO and HC emissions
The Self-Study Programme is not a Workshop Manual.
Please always refer to the relevant Service Literature for all inspection, adjustment and repair instructions.
