FUEL SYSTEM
The fuel system of the TAE 125 installation includes a variant of the
original standard tank of the DR400, plus a level sender and display, and
an independent low-level warning light. An additional sensor and display
for fuel temperature is installed.
The fuel flows out of the tank to the Fuel Selector Valve which has
positions ON and OFF.
The electrically driven fuel pump supports the fuel flow to the filter
module if required. Upstream to the fuel filter module a thermostat-
controlled fuel pre-heater is installed. Then, the engine-driven feed pump
and the high-pressure pump supply the rail, from where the fuel is
injected into the cylinders depending upon the position of the thrust lever
and regulation by the FADEC.
Surplus fuel flows to the filter module and then through the fuel selector
valve back into the tank. A temperature sensor in the filter module
controls the heat exchange between the fuel feed and return. Since
Diesel fuel tends to form paraffin at low temperatures, the information in
Section 2 “Limitations“ pertaining to fuel temperature have to be
observed. The fuel return ensures a quicker warm up of the fuel in the
tank.
