Working
principle
and
types
of
temperature
sensors
commonly
used
in
automobiles
Temperature
is
an
important
parameter
reflecting
the
state
of
engine
thermal
load.
In
order
to
ensure
that
the
control
system
can
accurately
control
the
working
parameters
of
the
engine,
it
is
necessary
to
monitor
the
engine
coolant
temperature,
intake
temperature
and
exhaust
temperature
at
any
time,
so
as
to
correct
the
control
parameters,
calculate
the
mass
flow
of
the
intake
air
from
the
cylinder,
and
perform
exhaust
purification
treatment.
The
Coolant
Temperature
Sensor
(CTS)
is
usually
called
the
water
temperature
sensor,
which
is
installed
on
the
engine
coolant
outlet
pipe.
Its
function
is
to
detect
the
temperature
of
the
engine
coolant,
and
convert
the
temperature
signal
into
an
electrical
signal
and
send
it
to
the
ECu.
ECU
corrects
the
injection
time
and
ignition
time
according
to
the
temperature
signal
of
the
engine,
so
as
to
make
the
engine
work
in
the
best
condition.
The
Intake
Air
Temperature
Sensor
(IATS)
is
installed
in
the
intake
pipe,
and
its
function
is
to
detect
the
temperature
of
the
intake
air,
and
convert
the
temperature
signal
into
an
electrical
signal
and
send
it
to
the
ECU.
The
intake
air
temperature
signal
is
a
correction
signal
for
various
control
functions.
If
the
intake
air
temperature
sensor
signal
is
interrupted,
it
will
cause
difficulty
in
hot
start
and
increase
exhaust
gas
emissions.
As
we
all
know,
air
weight
is
related
to
intake
air
temperature
and
atmospheric
(intake)
pressure.
When
the
intake
air
temperature
is
low,
the
air
density
is
high,
and
the
weight
of
the
same
volume
of
gas
increases;
conversely,
when
the
intake
temperature
increases,
the
weight
of
the
same
volume
of
gas
will
decrease.
In
the
fuel
injection
system
using
manifold
pressure
type,
vane
type,
Kalman
vortex
type,
core
type
air
flow
sensor,
since
the
air
flow
measured
by
the
air
flow
sensor
is
volume
flow,
it
is
necessary
to
be
equipped
with
intake
air
temperature
sensor
and
atmosphere
Pressure
Sensor.
The
ECU
corrects
the
fuel
injection
volume
according
to
the
engine's
intake
air
temperature
and
pressure
signals,
so
that
the
engine
can
automatically
adapt
to
changes
in
the
external
environment
temperature
(cold,
high
temperature)
and
pressure
(plateau,
plain).
When
the
intake
air
temperature
is
low
(high
air
density),
the
resistance
of
the
thermistor
is
large,
and
the
signal
voltage
of
the
sensor
input
to
the
ECU
is
high,
and
the
ECU
controls
the
injector
to
increase
the
fuel
injection;
on
the
contrary,
when
the
intake
air
temperature
is
high
(low
air
density)
),
the
thermistor
resistance
value
is
small,
the
signal
voltage
of
the
sensor
input
to
the
ECU
is
low,
the
ECU
will
control
the
fuel
injector
to
reduce
the
fuel
injection
volume.
There
are
many
types
of
temperature
sensors,
commonly
used
are
thermistor
type,
metal
thermal
resistance
type,
wire
wound
resistance
type,
transistor
type
and
so
on.
Thermistors
can
be
divided
into
positive
temperature
coefficient
(PTC)
type
thermistors,
negative
temperature
coefficient
(Negative
Temperature
Coefficient,
NTC)
type
thermistors,
critical
temperature
resistance
(critical
temperature
resistor,
CTR)
and
Linear
thermistor.
Commonly
used
thermistors
include
negative
temperature
coefficient
type
and
positive
temperature
coefficient
type.
Automobiles
generally
use
NTC
thermistor
temperature
sensors,
such
as
coolant
temperature
sensor
(CTS),
intake
air
temperature
sensor
(IATS),
exhaust
temperature
sensor
(Ex-haust
Air
Temperature
Sensor,
EATS),
fuel
temperature
sensor
(FuelTemperature
Sensor)
,
FTs)
etc.
