How does the ECU Help to Diminish Vehicular Emission

HOW DOES THE ECU HELP TO DIMINISH VEHICULAR
EMISSION?
2
The presence of oxygen inside the combustion
chamber is really important to completely burn
the fuel.
3
Lack of sufficient amount of oxygen might
drastically affect the efficiency of the
combustion engine and also increases the rate of
emission of unburned hydrocarbons.
4
Besides, the presence of impurities in the fuel
like nitrogen and sulfur would yield oxides of
nitrogen and sulfur which are responsible for
acid rain.
5
The engine control unit (ECU) plays a vital role
to reduce the rate of vehicular emissions.
6
It monitors the composition of the exhaust gases
and takes suitable actions to get rid of the
environmental pollutants.

ROLE OF THE ECU TO CONTROL VEHICULAR EMISSION
8
THE ECU USES SENSOR READINGS
9
Different types of sensors located in different
parts of a car provide data to the ECU.
10
The ECU monitors the oxygen level in the intake
manifold and the exhaust system with the help of
oxygen sensors.
11
It monitors and regulates the variable valve
timing and other types of valves.
12
By doing so, it stabilizes the performance of the
engine and to reduce the emission of different
types of pollutants.
13
Malfunctions in those sensors might limit the
ability of an ECU to work smoothly.
14
THE ECU REGULATES THE AIR TO FUEL RATIO
15
One liter of fuel needs about 14.7 liters of
oxygen to burn completely with minimal emission
of unburned hydrocarbons.
16
Injection of a huge amount of fuel or oxygen to
the combustion chamber might adversely affect the
power output of an engine.
17
Besides, it also increases the emission of toxic
pollutants.
18
Similarly, if the quantity of oxygen or fuel
declines inside the combustion chamber, then it
would also adversely affects the performance of
an engine and increases the emission level.
19
The primary function of the ECU is to regulate
the fuel to air ratio inside the combustion
chamber.
20
Malfunctions in such an important part of the car
could have serious consequences.
21
BOTTOM LINE
22
The fact is that the ECU plays an important role
to reduce the vehicular emission.
23
Any kinds of mechanical or electrical problems in
the ECU or the sensors associated with it not
only affects the performance of a car but also
increases the rate of emission of toxic
pollutants.
24
So, it needs special attention to do its job
efficiently.
25
Appearance of abnormal signs which shows that the
ECU has problems should not be overlooked.
