3. • Diesel motors are assuming a fundamental part of Road and ocean transport,
Agriculture, mining and numerous different businesses.
• Thinking about the accessible fuel assets and the present mechanical
improvement, Diesel fuel is obviously imperative.
• In spite, we can’t disregard the destructive impacts of the extensive mass of the
consumed gases, which disintegrates the immaculateness of our condition regular.
• While consistent research is going ahead to decrease the harmful substance of
diesel fumes, the diesel control packs discover the regularly expanding
applications and request.
• This undertaking is an endeavor to lessen the lethal substance of diesel fumes
before it is transmitted to the air. This framework can be securely utilized for
diesel control packs which could be utilized as a part of inflammable airs, for
example, refineries, chemicals handling enterprises, open cost mines and other
restricted zones, which requests the requirement for diesel control packs.
Introduction :-
4. Motor Vehicle
Emissions
Almost 1/3 of our air
pollution comes from
gasoline burned by vehicles.
According to the U.S.
Department of
Transportation, Americans
drove their vehicles over 2.6
trillion miles in 1998.
Over 90 percent of that
mileage was driven by
passenger vehicles. The rest
was driven by trucks and
buses.
5. Controlling Vehicle Emissions
The Clean Air Act, passed in 1970 and
strengthened in 1990, gives the Environmental
Protection Agency (EPA) the authority to regulate
vehicle emissions in the U.S.
The EPA required the gradual elimination of lead
in gasoline, decreasing lead pollution by more
than 90 percent in the United States.
In addition, catalytic converters, required in all
automobiles, clean exhaust gases of pollutants
before pollutants are able to exit the tail pipe.
8. SMOG
Smog is urban air pollution
composed of a mixture of
smoke and fog produced from
industrial pollutants and
burning fuels.
Smog results from chemical
reactions that involve sunlight,
air, automobile exhaust, and
ozone.
Pollutants released by vehicles
and industries are the main
causes of smog.
9. Temperature Inversions
The circulation of air in the atmosphere usually keeps air pollution
from reaching dangerous levels.
During the day, the sun heats the surface of the Earth and the air
near the Earth. The warm air rises through the cooler air above it
and carries pollutants away from the ground, and into the
atmosphere.
Sometimes, however, pollution is trapped near the Earth’s surface
by a temperature inversion
11. Carbon air filters are the filters most commonly used to remove
gases. They are designed to filter gases through a bed of
activated carbon (also called activated charcoal) and are usually
used to combat volatile organic compounds (VOCs) released
from common household products.
CARBON FILTER
12. Dust collector
A dust collector is a system used to
enhance the quality of air released
from industrial and commercial
processes by collecting dust and
other impurities from air or gas.
Designed to handle high-volume
dust loads, a dust collector system
consists of a blower, dust filter, a
filter-cleaning system, and a dust
receptacle or dust removal system. It
is distinguished from air purifiers,
which use disposable filters to
remove dust.
13. • Exhaust Gas Recirculation is an efficient method to reduce CO, COx emissions
from the engine.
• It works by recirculating a quantity of exhaust gas back to the engine cylinders.
• Intermixing the recirculated gas with incoming air reduces the amount of
available O2 to the combustion And lowers the peak temperature of combustion.
• Recirculation is usually achieved by piping a route from the exhaust manifold to
the intake manifold.
• A control valve within the circuit regulates and times the gas flow.

14. Diesel Black Carbon Impacts :-
• Climate.
1. Black carbon is a strongly light-absorbing carbonaceous aerosol produced
under conditions of Incomplete fossil fuel and biomass combustion.
2. These very small particles consist of a mixture of graphitic and amorphous
carbon. When emitted, they persist on average in the atmosphere for more
than a week until they come into contact with a surface or are washed out of the
atmosphere by precipitation.
• Health.
1. Factors such as engine type and operating conditions, fuel, and engine
technology influence the characteristics of diesel exhaust, causing significant
variation in the mix of exhaust gases and the size and composition of the
particulate matter.
2. Vehicle emissions undergo further near-road and atmospheric chemical
transformations that result in the formation of secondary particles and gases
15. How can the black smoke be reduced?
• The industry has been developing innovative ideas to reduce exhaust emissions for
many years. A number of solutions are available and these range from Exhaust Gas
Recirculation (EGR) to Dual Fuel conversions.
• The most effective solutions are designed specifically to deal with particulates and
can reduce the DPM emissions in the exhaust by up to 99%, from startup. These
systems are known as Diesel Particulate Filters or Soot Filters.
16. • Effectiveness of the vehicle is expanded
• Fuel utilization is less when contrasted with common vehicle
• Less contamination
• pollution under control.
Advantages :-
17. • The additional cost is required.
• Additional space is required to introduce this course
of action in vehicles.
Disadvantages :-
18. • All Diesel and petroleum motor application.
• Car Applications.
• Ship and marine.
• Industrial boiler
