How Exhaust Gas Recirculation (EGR) System Works in Hindi
Вставка
- Опубліковано 18 сер 2024
- The Exhaust Gas Recirculation or EGR system is one of several vehicle emission control systems. It helps reduce the amount of the nitrogen oxides (NOx) in the exhaust gases. Nitrogen oxides are normally formed in the process of combustion in the engine cylinders. However, their formation increases dramatically at higher combustion temperatures (above 1600 °C or 2912 °F).
Higher combustion temperatures are also harmful to the engine. One of the effects caused by high combustion temperatures is a pre-ignition or detonation (pinging), when the air/fuel mixture ignites in the cylinders not from the spark, but from excessive heat. Because it happens at the wrong time, before the spark, the detonation adds strain on engine components.
The EGR system reduces the combustion temperature by diverting a small portion of the exhaust gases back into the intake manifold. Exhaust gases are no longer combustible. Diluting the intake air with exhaust gases makes the air/fuel charge less combustible.
The engine computer (PCM) opens or closes the EGR valve to control the flow within the EGR system. The EGR valve connects the exhaust manifold to the intake manifold. The EGR valve is normally closed. There is no EGR flow when the engine is cold, at idle, or during hard acceleration. The EGR flow is at its peak during steady cruising under moderate load.
The PCM periodically tests the EGR system along with other emission control systems. If the flow is more or less than expected, the PCM detects a fault and turns on the Check Engine light on the instrument panel.
There are different ways to monitor the EGR flow. Some cars use an EGR temperature sensor installed in the intake part of the EGR system. When the EGR valve opens, the temperature on the intake side rises from the hot exhaust gases.

बहुत ही आसान तरीके से आपने समझाया। शुक्रिया
Very good talent bahut Achcha bataya aapane
o Hello Sir egr sirf diesel gaadiyo me aata he aur diesel gaadiyo me spark plug kaha se aa gaya ?
Bhai EGR petrol gadio me bhi hota hai
@@devanshsharma8901 kaha hota hai Bhai petrol gaadi me😂
@@autospider4345 new k10 new ecco or me bhi hai maruti k vehicles me aa rha
Thank you sir aap ka video mujhe bahut achha lagta hai aur bahut kuchh sikhne ko milta hai
Aise hi video hamesa upload kare
Thanks
Good morning🌞🌞🌞 sir
Excellent EGR System
Sir aap bord pe hi pada te or ache se smj aata or sir doubt bhi clear ho jata diagram ke shat
My. Old. Mekanik. Tumare. Vidense. My. Bi kuch. Sikneko. Ml. Ra. Beta. Danyvad
इतना अच्छे से बताया थैंक्यू
Sir , your way of teaching is too good , but please baar baar haath mat jooda karo...
Thank you for EGR
Welcome
Very nice Sir
Thanks
Bhai aap bahut hi acche video banate ho yaar ek aisa video banaa hui thi yaar technology system wala
The Best
You have explained us in very simple language.
Luckily today I have do proper working EGR system through service station. Due to improper EGR car is get smoke.
👍👍👍
VERY NICE SIR
😊👍
Nice.... 🛠
👍👍
Hii.... Sir... Oil kyu Black Ho jata hai... Matlab crankcase ventilation function batao... I'm. Machenic.... 🛠
Excellent 👍. Till date I was thinking that EGR is for reducing pollution only.
Also make video on PCM sir.
Okay
Most helpful
Thanks
Very nice information 🙂
बहोत बढ़िया समझाने का प्रयास 🎉🎉🎉
Nice bro good work
How unmetered air can go directly to intake through EGR by bypassing Mass air flow sensor ? if more and more air goes it will stall engine,
Very nice explaination
👍👍
Tq for advising sir
Very well 👍🏻
Thanks
Aacha explain kiya sir thank you
Very nice presentation.
Very good information sir
Dear very informative and top notch video
Very nice explain sir
Very nice love you
yes pcm ke liye video banao
Dada ignation switch off korne engine off kiu hota he? Engine ka to four stroke to chalu he.
Ignation off k saath engine four stroke off hone KI Karan kya he?
Bahut confusion me hu
Thanks sir g
Welcome
Sir PCM &ECU PLZ MAKE THIS VIDEO'S 👍🙏
Okay
Pcm par video banniye sir
Bhai aapka bolne ka treqa bahoth zabardast hai.....mera sawal hai ke agar egr ko cancel karse kise wajah se to gadi ko koi nuqsaan to nahi hoga aur egr se gadi ka mileage badhta hai kia....???? please reply zarur karna....thanks
Nice your information
Superb bro 👏👏
If schematic diagram screen time would be more in the video that would be more interesting and helpful
🙏Sir good information thank you sir
Good sir
एलिसन ट्रांसमिशन के बारे में बताएं। जो ऑटोमेटिक। गियरबॉक्स उनके बारे में भी एक वीडियो बनाएं। torque converter oil pump Pressure Pump पर भी एक विशेष वीडियो बनाएं।
Okay 👍
Sir aap stage v engine par video banye kuch
Vary good
Very good
Thanks
Sir three cylinder OBM per ek vidio banaye And DIDR information bhi bataye
Excellent
Nice❤
Great information
Great details
Nice
Well explained
Thanks
If you explain all videos with animation it will be more effective and understanding
Awesome
Sir deffrencial par video banao
Differential pe video upload kiye hai
Sar easier aur turbocharger mein kya fark hota hai
Very nice but your voice is too low... please increase your voice
I like video
👍👍👍
Sir ignition taiming retar andvance ka samjadi jeyA
Jb flue gases fresh air se milengi tb temp Increase Hoga ki decrease hoga.
Sir please make a video on Pcm
Okay
Sir diesel engine ke bare mai bataye
Please make a video on pcm
Ignition system and induction ki bhi sir ji please 🙏
Okay
good video
Thanks
Nice information
VVT technology system truck's engine me kyu nahi Ata hai sir thank you
thanksss🙏🤩🇳🇵🇳🇵✍️🇳🇵
Welcome
Sir aap manually samjate h hum chahte h ki aap board par samjhayenge to or bi achha rahega humare liye kyoki sir yese m smaj m kam aata h
Pranam sir
Please make the interview ques & ans which you made the video within one month
Okay
Super
Sir namaskar.
Exhaust gases doesn't go directly into the intake manifold but they first cooled down by intercooler and then sent into intake manifold
New cars me use Kiya ja rha
Nice. Whether EGR system helps in increasing pickup and also in improving fuel economy?
No, In EGR system performance reduces & In SCR system performance increases.
@@GoGomaintenance yes
Dear Sir,
Please make a video regarding Urea/adblue consumption & diesel consumption ratio.
1Ltr diesel consumption how much Urea consumption.
SCR pe video banayie 🙏
Good evening sir , sir EGR ko hm air compressed vehicle m kese use kr skte h
bro mahindra bolero slx 2014 model egr ko clean karne k liye outlet pipe hose se disconnect kar k air filter khol k diesel daalne k baad gaadi ko start kar k race dene se clean kar sakte hai kya ?
Does the faulty EGR valve effect the mileage
Yes
Sir please OBD inforfamtion
Okay
Bhai authorise service station Wale egr section clean kyo nahi karte hai.🙏🇮🇳🙏💐
PCM pr video 🎥 bnaye
Sar petrol car me pcv valve aata he to diesal kar aata he ya nahi
Adhuri information
Sir meri car ka EGR khrab hogya hai to uska pluck nikal diya hai abhi to bina EGR k car chalane se car k engine p koi effect to nhi hoga?
3:03, exhaust gas EGR ke through intake me jayengi to cylinder ke andar ka temp kam kese ho jayega?
Gjb
👍
Pilis 🙏 sir gi bike injan me kon kitne samay me change karni chahia part taki sapty rah sake video pilis 🙏
Okay
Diesel vehicle ke bare me bta rhe ho gasoline
Sr back comperssar kaise check karte hai ispe ham back comperssar wapis ksise Check kare ae open aaya tha to kaise check kre bat as ye
How to increase the EGR RATE SIR??
Boot hi galat bataya par samzaneka tarika thik hai thoda jada study kar ke aaiy
Kaliaa sir ac ka video banao.,..
Sar app mujhe ye bataye ki egr se jo air ati hai to grm rhti hi na fir to intec air ko kese cold kregi🫸🫷
EGR की गैस जब fresh हवा से mix होगी तो वो mixture कम ज्वलनशील बन जाता है और केवल spark plug की चिंगारी से ही जलता है। अतः fuel हवा का mixture सिलिंडर में बढ़े हुए तापमान से नहीं जलता और तापमान धीरे धीरे कम आ जाता है।
Pcm or Ecu ek hi h ya alg alg
Sir PCM Pe Video Banaye
Okay
Ecm ka video banav sar ji
Sir upsc cse 2021 mains m 19 marks m question aya h isko thoda explain kr do please Question What do you understand by the term EGR ?Explain how EGRvreduces Nox emission in CI engines.
Mere car me coolant bar bar kam ho jata h topup krna padta h
Company ne thermostate change kiya uske bad bhi overheating problm aa rh h kya reason ho skta h jabki koi leakage nhi new tata altroz h sirf 3000 km chali h
