* KSB 'Kaltstartbeschleuniger' Cold starting timing advance system.
First used 1975. A number of different methods are employed to advance the timing for cold starting and low speed cold running.
Mechanical System. A lever is pulled which turns a cam that pushes the timing piston to provide about 5 degree advance at no load. At above approximately 2200rpm this has no effect on timing.

'Wax Motor' system. A solenoid is activated but is held open by a wax plug that melts as the engine warms allowing the solenoid valve to close. While the valve is held open the transfer pump pressure regulation valve is overridden allowing higher pressure to be made within the pump housing. These higher pressures provide a 5 degree advance that reduces with engine speed. When the engine is stopped the power to the solenoid is cut, opening the valve. As the engine cools the wax solidifies.

Thermo valve system. A vacuum pump acts on a dual stage diaphragm operated by a coolant temperature activated thermo valve. This system applies 8° injection timing advance below 7° Celsius, and 5° below 20° Celsius.

Electrical system. Similar to the wax motor system except the solenoid opens when powered. The power to the solenoid is switched on by a temperature switch in the coolant system.
