EGR System Working || EGR Kaise kaam karta hai. (‎@cargarage143 )
In internal combustion engines, exhaust gas recirculation (EGR) is a nitrogen oxide (NOx) emissions reduction technique used in petrol/gasoline, diesel engines and some hydrogen engines. EGR works by recirculating a portion of an engine's exhaust gas back to the engine cylinders. The exhaust gas displaces atmospheric air and reduces O2 in the combustion chamber. Reducing the amount of oxygen reduces the amount of fuel that can burn in the cylinder thereby reducing peak in-cylinder temperatures. The actual amount of recirculated exhaust gas varies with the engine operating parameters.
In the combustion cylinder, NOx is produced by high-temperature mixtures of atmospheric nitrogen and oxygen, and this usually occurs at cylinder peak pressure. In a spark-ignition engine, an ancillary benefit of recirculating exhaust gases via an external EGR valve is an increase in efficiency, as charge dilution allows a larger throttle position and reduces associated pumping losses. Mazda's turbocharged SkyActiv gasoline direct injection engine uses recirculated and cooled exhaust gases to reduce combustion chamber temperatures, thereby permitting the engine to run at higher boost levels before the air-fuel mixture must be enriched to prevent engine knocking.
In a gasoline engine, this inert exhaust displaces some amount of combustible charge in the cylinder, effectively reducing the quantity of charge available for combustion without affecting the air-fuel ratio. In a diesel engine, the exhaust gas replaces some of the excess oxygen in the pre-combustion mixture. Because NOx forms primarily when a mixture of nitrogen and oxygen is subjected to high temperature, the lower combustion chamber temperatures caused by EGR reduces the amount of NOx that the combustion process generates. Gases re-introduced from EGR systems will also contain near equilibrium
concentrations of NOx and CO; the small fraction initially within the combustion chamber inhibits the total net production of these and other pollutants when sampled on a time average. Chemical properties of different fuels limit how much EGR may be used. For example is more tolerant to EGR than gasoline

Thanks for watching.

Thankyou sir....

[@priyadarshanjha1575]

Thank you for sharing a good technical knowledge regarding EGR

[@sudhanshusekharmahapatra5078]

Car Engine overall kyu karana padata he
Iske ak vedio banayo sir ji

[@nandlalyadav7352]

Very nice thank u

[@mdzahid3423]

Ok thanks sir

[@taranjeetsingh3295]

EGR kese clean kare. Is per ek video bnaye pls

[@raosahab3488]

Complete egr khol k diesel paani or hwa se saaf krke waapis lga do

[@SanjaySharma-oy3dp]

Thanks for your information, I owned second hand Tata hexa 42000 km driven and come to know about its EGR issue of the other owners can you please tell me how we can detect prior to it malfunction so that can get it cleaned in time because what indication you have told is same as clutch plate failure to which I come across a few days before and how can we avoid it's failure.

Nice

To aapke kahne ka matlab hai ki kcuch gais me hi nitrogen yani egr ke paip me jo gais ghusa usi me nitrogen hai aap btao egr ko pta hai kya😢

EGR system is fitted in a vehicle only to meet pollution norms applicable as per guidelines of Govt of India. At present BS-VI norms are applicable. Mainly NOx are controlled through it.
