The document discusses the exhaust gas recirculation (EGR) technology, which is used to control automobile pollution by reducing harmful exhaust emissions. It outlines the main components of the EGR system, its applications in various manufacturers, and highlights its advantages such as lower emissions and low maintenance, alongside drawbacks like high initial costs and limitations for petrol engines. The conclusion emphasizes EGR's effectiveness in controlling NOx emissions and its reliability in fuel consumption.

2. INTRODUCTION
Automobiles are the major contributors for pollution, which
causes dangerous effects to human beings and animals.
EXHAUST GAS RECIRCULATION technology is for controlling the
environmental pollution.
It plays a major role in preventing the air pollution.
 This system reduces dangerous exhaust gases coming from
automobiles and these emissions are controlled by EXHAUST
GAS RECIRCULATION.

11. MERITS AND DEMERITS
MERITS:
 Emissions are controlled at greater level.
 Low maintenance.
 No need of skilled mechanics to repair this system.
 Can be upgradable to BS-6.
DEMERITS:
 Not suitable for petrol engines under some conditions.
 Only for heavy duty diesel engines.
 Initial cost is high.
 No decrease in sound pollution.

12. CONCLUSION
 By using EXHAUST GAS RECIRCULATION in engines, the
emissions are very much controlled due to lower amount
of Nox entering into atmosphere.
 This method is very reliable in terms of fuel
consumption.
