7. Fuel TemperatureSensor (FTS)

(Fig. 231)

This sensor monitors the temperature of fuel

entering in the HP pump. The fuel temperature

sensor measures fuel temperature on the pump

hydraulic head in the low pressure circuit,

between the transfer pump outlet and the inlet

to the HP pumping stage. This sensor information

issued tomodify rail pressure control, injection etc.

8. Inlet Metering Valve (IMV)

(Fig. 231)

This controls fuel flow into pumping element in

order to control rail pressure. This sensor is in built

with HP Pump.

9. Venturi

(Fig. 231)

It is an integral part of High pressure pump. It has

inlet & outlet connections. One connection comes

from injector back leak circuit & the other

connection goes to the fuel tank (return Line), in

between there is a "T" connector which goes to

the fuel filter.
