The venturi nozzle
The intaken air is guided through a ceramic housing,
which is shaped as a venturi nozzle. As a result of this,
the air delivered by the combusion air blower is acce-
lerated to approx. 50 m/s.
The incoming fuel is therefore drawn from the fuel line
and swirled.
The fuel pre-heater
The Thermo Top V system is fitted with a PTC element
for pre-heating fuel; this enables the use of RME
(rapeseed methyl ester).
The fuel is heated directly prior to emerging from the
fuel line. To do this, the PTC heater element is switched
on for one minute at ambient temperatures of less
than 5°C.
