Fuel Injection (FI) System Working in Motorcycle/Scooter | बाइक से कार्बोरेटर क्यों हटाया गया?

- The engine of the bike has to be provided with an air fuel mixture for proper combustion inside. So the mixture if not proper does not provide a proper balance leading to improper performance. For an average bike using unleaded fuel the mixture has to be in the range of 12-14.7 parts of air to one part of fuel. This is the band where the maximum performance with most efficiency is found.
Now in this there are terms like a lean mix and a rich mix. When the amount of fuel to air is on the higher side (i.e. 12) then it is a rich mixture to bring out the maximum performance. But when the same figure hovers around 14.7 then it is a lean mix to bring out the highest efficiency by compromising on performance. This is what has to be manually adjusted on a carburetor using a big screwdriver.
All these hassles are taken care of in a Fuel Injection Unit. For starters it is electronically controlled using an ECU (Electronic Control Unit). It contains fuel maps which adjust the air fuel mixture according to the riding conditions.
When the engine is running, instead of regular valves, the fuel from the pressure pump is directly injected into the combustion chamber using nozzles. The sensor attached to the nozzle makes sure the right amount of fuel is inserted inside. This rate of fuel injection is controlled by the ECU. So for an economical ride the mixture is kept lean while the performance mapping allows for a rich mixture.
Now this is all theoretical explanation, but when we check out how the function is in the real world, it is all very fast. Consider this for starters, when you are riding in the city traffic, that means continuous stop and go; in this case the ECU is continuously monitoring your throttle input. When the throttle is given a gentle pull, the lean mixture is provided; but if you give a sudden pull of outright acceleration, a rich mixture is allowed for maximum power.
The same is in the case of cruising. While you are cruising on the highway at a steady pace, the ECU calculates the right mixture for the fueling and hence provides a combination of lean and semi-rich mixture alternately to give the best output. But when you give a sudden pull to the throttle, the ECU detects it immediately and gives a rich mixture. All these capabilities are only possible for fuel injection and not for carburetors.

Bhai kese bante hai loco pilot
Bhai train chalana hai bike nahi
Bhai apki video kafi nowlegeable hogi thanx brother fuel se related topic butane ke liye 👌👍
भाई आपका भिडियो देखकर बहुद जानकारि मिलता है जो हर किसि कै लिए जरुरी है जिनकै पास सवारी साधन है 😊
Sir mai RTO inspector ki teyari kar rha hu apke sabhi video dekhe bhut Hi achha expanded kiya h apne🙏🙏🙏
Again very informative. Love to see a video regarding compressor ratio . Thanks
👍👍👍
F I system ke baare mei aapne bohot hi anmol knowledge diya hai...thanks 🙏👍🌹

Bahut dino k baad jo video chahiye tha ab jaa ke mila
😊👍👍👍
सर आपका समझाने का तरीका बहुत ही बढ़िया है । वाह
Great work and explanation brother Thanks you so much 🙏🙏👍
Bahut badiya ser, bahut amchi tarah samajala bataya hai
Bahut bhadiya vidio hai sir sari cheez clear ho gaya.Nice vidio👌👌👌
Your way of explanation is amazing.... ❤️
बहुत अच्छा तरीका से बताया आपने धन्यवाद 🙏
Sir, I have a great way of watching your videos,
😊👍
Bohot bariya, bohot hi bariya
आप की वीडियो में बेस्ट content होता है
Thanks
Welcome
MECHANICAL TECH HINDI 100cc ke bike me fi system ka koi phayada nhi hota hai.
Fi system 180+ cc bikes ke liye acch ho sakta hai kyoki ase bike ko kabhi normal kabhi speed me chalaya jata hai.
MECHANICAL TECH HINDI bs6 lagu hone ke bad koi comapny ne officialy milege claim nhi kiya sab 10% more milege kah dete hai jo bakwas hai.
Pollution control ho sakta hai
@@abhishekkumar-mm6bt आप का सोचना गलत है अगर आप के पास कोई compani का bs4 और bs6 है तो आप घर पर comparison कर के देख सकते है आप को अंतर पता चल जाये गा
Very good information bhai .. bahut a66a samjaya
Thank you for the knowledge sir 😊
felt good to listen your lesson bro,superb
Bahut hi achchha laga video sir ji bus aesa hi video banate rhe
