WHAT ARE THE PRIMARY FUNCTIONS OF AN ECU IN A CAR?
2
An engine control unit (ECU) could be considered
as the brain of a car as it helps to regulate the
performance of the engine.
3
It uses the data provided by different types of
sensors located in the engine bay, intake
manifold, and exhaust system to do its job.
4
If it fails to do its job, then it could bring
down the vehicle to a halt in the middle of
nowhere.
5
So, everyone should be aware of the role played
by an ECU in the performance of a car.

FUNCTIONS OF AN ECU
7

• REGULATES THE TIMING OF IGNITION
• REGULATES THE AIR TO FUEL MIXTURE
• REGULATES VARIABLE VALVE TIMING AND IDLE SPEED
• REDUCES VEHICULAR POLLUTION

8
REGULATES THE TIMING OF IGNITION
9
Spark plug generates the spark required to ignite
the combustion chamber of an engine.
10
However, the timing of ignition is a really
critical aspect of the internal combustion
process.
11
Any kinds of errors in the timing of ignition
could adversely affect the performance of an
engine or could event leads to an engine misfire.
12
So, signs which show that that the ECU is failing
to regulate the ignition process should not be
neglected.
13
REGULATES THE AIR TO FUEL MIXTURE
14
Fuel needs a suitable amount of oxygen in order
to burn completely.
15
The air to fuel ratio should be 14.7 to1 inside
the combustion chamber of the engine and the ECU
regulates the air to fuel ratio.
16
Faults in the ECU or the sensors it uses to
gather data might negatively affect this ratio.
17
The presence of an excess amount of fuel or air
inside the combustion chamber could adversely
affect the efficiency of an engine.
18
Besides, it could lead to engine misfire and
could also trigger other kinds of mechanical
errors in the car.
19
REGULATES VARIABLE VALVE TIMING AND IDLE SPEED
20
The ECU regulates the opening and closing of
valves and thus controls the performance and
efficiency of the engine.
21
Besides, it also regulates idle speed through
programmable throttle stop.
22
Thus, any kind of malfunctions in such an
important system might impair the engine.
23
REDUCES VEHICULAR POLLUTION
24
The ECU regulates the timing of ignition and fuel
to air ratio inside the combustion chamber of the
engine.
25
By doing so, it also regulates the emission of
different types of environmental pollutants
including unburned hydrocarbons.
26
BOTTOM LINE
27
Invention and use of the ECU in a car has
significantly increased its performance.
28
Malfunctions in such an important part of the car
could jeopardize the performance of a car.
29
Thus, efforts should be made to fix such problems
in time.
