SUPPLEMENTARY

HEATER

(where provided)

The supplementary heater can

work with the engine off or on and it

allows the following: 

– to heat the engine coolant before

start up

– to reduce the engine warming up

time after cold starting

– to warm up the passenger com-

partment before departure

– to remove ice or condensate from

the windows.

Using the heater in winter has the

following advantages:

– to reduce engine wear

– to reduce polluting emissions

– to improve comfort during dri-

ving and stops

– to improve safety.

The supplementary heater function

is useful to integrate the engine

coolant warming up during driving

in order to reach and keep the opti-

mal working temperature of the pas-

senger compartment heater in the

quickest way, especially if the cli-

mate is extremely cold.

The system is composed of:

– a heating unit

– an electric pump for the engine

coolant circulation

– an exhaust pipe with muffler

– an electric pump metering the

fuels

– a fuel delivery pipe

– a sensor for outside air tempera-

ture.

The system is connected to the car

through the engine cooling system,

the fuel system and the electric sys-

tem. The coolant coming out from

the engine is conveyed to the heater

and made flow in the circuit by an

electric pump. The heater burner is

supplied with the car fuel taken

directly from the tank by means of

an electric pulse pump and then

conveyed to the appropriate system

pipe. The heater control unit sup-

plies directly both electric pumps

(fuel and coolant), activates and

checks the heater functions.

The supplementary heating system

works both with the engine running

and the engine stationary. These two

conditions determine the type of sys-

tem operating mode:

– when the engine is stationary the

supplementary heater can work in

“programmable heater” or “parked-

car heater” mode;
