Air Mass flow sensor (AMF):
Amount of air quantity entering the engine is given by
this sensor,This input is used by the ECU for corrections
of fuel quantity based on amount of air availability and
for optimised exhaust gas circulation.
Air mass flow sensor
7.
Coolant Temperature Sensor:
A semiconductor material changes its resistance
when exposed to variable temperature source.
Resistance decreases as temperature increases. This
sensor provides engine operating temperature
input to ECU.This sensor is fitted on upper cooling
line.Corrections for injection parameters is done by the
ECU based on coolant temperature to run the engine
with maximum efficiency at all temperatures.
8 Fuel Temperature Sensor:
This sensor monitors the temperatuer of the fuel
entering the fuel injection pump.This sensor
information is used to modify rail pressure control
terms at extreme temperatures.
9 Inlet Metering Valve (IMV):
This controls fuel flow into HP chambers in order to
control rail pressure.This sensor is inbuilt with HP
Pump.
