Emission Control For Diesel Engine – Mechanical Project

Project On Emission Control For Diesel Engine


Diesel power invitably finds a very important role in the development of the plant’s economy and technical growth. Inspite of their high thermal efficiency, one cannot ignore the fact about the effect of their exhaust, in the atmosphere. It is a well known fact that the toxic gases emitted in diesel engines are less than the engines. Due to high cost of petrol, diesel engines are more in use. Anticipating the use of diesel engines, even more in the near future; this system developed can be used to control the toxic gases, coming out of the diesel engines.

These toxic gases are harmful not only to the atmosphere, but also to the human and animal race. Objective of this project is to design & fabricate a simple system, where the toxic levels are controlled through chemical reaction to more agreeable level. This system acts itself as a silencer; there is no need to separate the silencer. The whole assembly is fitted in the exhaust pipe; it does not give rise to any complications in assembling it. This system is VERY COST EFFECTIVE AND MORE ECONOMICAL.

Diesel engines are playing a vital role in Road and sea transport, Agriculture, mining and many other industries. Considering the available fuel resources and the present technological development, Diesel fuel is evidently indispensable. In general, the consumption of fuel is an index for finding out the economic strength of any country. Inspite, we cannot ignore the harmful effects of the large mass of the burnt gases, which erodes the purity of our environment everyday.
It is especially so, inmost developed countries like USA and EUROPE. While, constant research is going on to reduce the toxic content of diesel exhaust, the diesel power packs find the ever increasing applications and demand. This project is an attempt to reduce the toxic content of diesel exhaust, before it is emitted to the atmosphere. This system can be safely used for diesel power packs which could be used in inflammable atmospheres, such as refineries, chemicals processing industries, open cost mines and other confined areas, which demands the need for diesel power packs.

The problems that arise from the Diesel utilization in inflammable environment may be listed as follows:
1. Gases and particulate in engine emission.
2. Heat and Humidity.
3. Risk of explosion and fires.
4. Transportation and storage of fuel.
5. High speed in long hauls.
6. Risk of trackless vehicles entering inadequately ventilated areas.
7. Noise.
This section examines the first two of these problems and suggests means by which they may be reduced or overcome.


In addition to heat and water-vapor, the pollutants in diesel exhaust are,
a) Carbon monoxide (CO)
b) Carbon dioxide (CO2)
c) Oxides of Nitrogen (Nox)
d) Sulphur dioxide(SO2)
e) Particulate and Unburned Hydrocarbons (UBHC)
f) Respirable combustible Dust (RCD)
The above polluting contents in the diesel engine exhaust are to be controlled by the scrubbing method, details of which are followed.


  • Efficiency of the vehicle is increased.
  • Fuel consumption is less when compared to ordinary vehicle.
  • Less pollution.


  • Additional cost is required.
  • Additional space is required to install this arrangement in vehicles.

  1. I am final year mechanical engineering student, as per the academic requirements we have to do one major project and i found out this blog.
    It seems interesting to work on it, but i wanted to know and learn more about this project. So i hope i will get help from your side.
