What is Fuel Injector and How it Works? | Hindi

A fuel injector is an electronically controlled mechanical device which is used to inject/spray the fuel into the engine for the preparation of correct air-fuel mixture which in turn provides efficient combustion to the engine.
The position of the fuel injectors differs for different engine designs but usually they are mounted on the engine head with a tip inside the combustion chamber of the engine.
Construction of Fuel Injectors:
The constructional design of a fuel injector resembles with the garden shower nozzle which is used to spray water over the ground grass, same purpose is fulfilled by a fuel injector but the difference is instead of water fuel, injector spray fuel inside the engine.
Electronically Controlled Fuel Injector:
This is a smart type of fuel injector which is controlled electronically by the electronic control unit of the engine which is also known as brain of modern engines.
Injector body- The body of this type of injector is a precisely designed hollow shell inside which all the other components are arranged.
Plunger- A plunger is used for the opening and closing of the nozzle but in electronically controlled fuel injector the opening of the nozzle is controlled electronically with the help of electromagnets.
Spring - A plunger spring is used to hold the plunger in its position in order to close the nozzle of the fuel injector when required.
Electromagnets - This type of injector is equipped with electromagnets just around the plunger which controls the opening of the nozzle by taking the electronic signal from the electronic control unit of the engine through the electronic plug or connection connecting the fuel injector with the electronic control unit of the engine.
Electronic plug/connection- At the top end of electronically controlled fuel injector a connection/plug is present through which the electronic signal from the electronic control unit of the engine is transferred to the electromagnets which in turn opens the nozzle in order to spray the fuel.
Working:
When we ON the ignition of the vehicle in order to start the engine, the fuel pump along with the electronic control unit of the engine.
The fuel pump start pumping the fuel to the fuel injector and the timing, amount and pressure of the fuel entering the fuel injector is governed by the electronic control unit.
The electronic control unit sends the electronic signal to the fuel injector with the help of the electronic connection, due to these electronic signals from the ECU the electromagnets inside the fuel injector got activated which in turn pushes the plunger outward results in opening of the nozzle and finally the spray of the fuel takes place.
After completing this particular cycle the electronic signal from the ECU stops which in turn deactivates the electromagnets due to which the plunger returns to its initial position results in closing of the nozzle and the spray of the fuel stops.
The closing of the nozzle is maintained by the plunger spring.
The wait is finally over. I am here with TH-cam's very first Mechanical Engineering Channel in HINDI.
In this channel i will upload videos related to mechanical engineering topics such as Automobile, Production, HMT, Thermodynamics, FM, CAD/CAM etc.

Bhiya car ka nozel kam karwane me kitna kharcha aata hai

[@raufeequemechatronics6753]

bhai bahut sare automobile channel reply nii kerte hai.agar kuchh puchhte hai to.kya ap reply karoge.
bhai mai apko topic du uspe vidio banaoge yakin mano bhai bahut important topic sara dunga.jo sara electrician se topic rahega .waise to bahut sara koi vidio youtube pe banaya hai per utna khas kuchh samjh me hii ata hai utna.
ap agar mujhse sahmat ho to
REPLY KARE JARUR.

[@MECHANICALTECHHINDI]

Aap topic do mai jarur video banauga

@@MECHANICALTECHHINDI thanks bhaii.normal car, truck , bus old model me starting ka wireing.is tarah rahta tha.ignition key se direct self starter moter me current jata hai tab start hota hai.
LEKIN AB BS4 ME WAISA NAHI .
SABSE PAHLE IGNITION KEY SE RELAY ME JATI HAI ,ECM ME V JATI HAI.TO .
TO SAB SE PAHLE BS4 KA STARTING KA WIRIENG KA VIDIO BANAYE.CAR SE LEKAR TAILOR TAK.VIDIO LAMBA HOGA TO V CHALEGA .?????

1uske bad fir pumb ka wiring ka vidio banaegaa kaise janege pump me current jaraha ya nahi.
2 injector ka wireing ka video
3 acelator ka vidio
baki dhire dhire bataunga plz ap is tooic pe vidio banaee.

[@raufeequemechatronics6753]

@@MECHANICALTECHHINDI sabse important bhai pure youtube me wireing ka color code ka vidio nahi hai. jaise
1.starting ka wireing color code black rhta hai.
2.headlight ka pink and blue,
3.earthing ka black.
YE COLOR CODE TATA KA GADIYOU ME RAHTA HAI COLOR

Sir ye petrol our disel car dono me hote he kaya

[@MECHANICALTECHHINDI]

Diesel me hota hai iske alawa jo petrol vehicle me fi hota hai usme hota hai

Aapne live session ke interview questions per video nahi bana ya 😥

[@MECHANICALTECHHINDI]

Live session per video kuch din me upload kar dege, abhi thoda bsy hai isliye nai kar pa rahe hai
