Capacitor Discharge Ignition system (CDI System) | Ignition system of SI engine

[@swarnakamalmandal7904]

Best video on KZbin about CDI System 🥰🥰🥰🥰🥰🥰🥰🥰🥰🥰

[@myvehicle6002]

great video! it explain the wok of the cdi system simply. clear sketch. keep it up!

[@sreenivasanm4303]

What a helpful explanation with schematic diagram!. No words to thank you. Please upload more videos. To fully understand this subject people must watch till the end. I had been looking for videos that would explain how the engine is stopped. This video has clearly explained that.

[@ziauddin7948]

excellent Capacitor discharge ignition CDI function & mechanism to generate high voltage current for spark plug # 👍👍

[@joshuaajoo1208]

Super, thanks for telling in English for the south Indians.. we don't know hindi

[@PRNadh]

Excellent way of explaining the system with circuit diagram.

[@gabewhisen3446]

Great explanation, English is usually spoken at a slower pace just relaying this to you to help you with your speech and not to be rude , if you speak in a more relaxed manner it helps to also relax your listening audience and there for set a mood for reception of information, personally I had to watch 3 times because I got over excited and I have no capacitor lol

[@Dr.AmitMandal]

No rude, might be accent factor....

[@harveshsinghthakur6667]

Very clear explanation and clear language. Thanks to give useful information

[@SanjayRaut-l4v]

superb

[@felsamlopez]

Wow good job 👍👍👍

[@shawol275]

wonderful explanation!

[@oneinmillion9815]

Simply Explained👌 👌 👌 ...

[@edge2science]

Thank you Very nice and most compleat

[@viveksinghal3768]

Good explanation

[@markflierl1624]

That was a great video.

[@Exploringway]

Your explanation way is very easy

[@AshiqurRahman]

how much voltage is produced by the trigger coil in real life scenerio? How much ampere current is flowed from trigger coil to scr switch? I need this information. I am trying to measure the engine rpm of my motorcycle...

[@anjansen8072]

Nice presentation

[@SANJAYGUPTA-wh6kw]

Excellent explain 👍

[@arjunm7692]

Thank you bhayya... Thank You ♥

[@biduttamachintyabagchi9806]

In my view, the best explanation.

[@210-patilmayuresharvind9]

thanks ...the video made me understand clearly..❣

[@shitalnandlaskar5049]

very well explained

[@MechaniclifeJDM]

Great 👍🏽

[@dalenassar9152]

Thanks for this great video, I have one question: Here the spark plug fires when the SCR CLOSES,and shorts the capacitor through the coil primary, I have always heard that the coil secondary fires when the primary switch (an SCR here) is OPENED, collapsing the primary field...can you help with an explanation for this. I am so interested, because I need my circuit to behave EXACTLY as yours does. Thanks so much!

[@Dr.AmitMandal]

Are you compairing it with contact breaker type ignition system?

[@umeshmanappadan819]

Super explaintion

[@mgr4733]

Awesome explanation

[@prasadcholake2408]

Very nice explanation

[@raymondgarafano8604]

great explanation ! Just wondering though, does auto battery take the place of exciter generator?

[@RRakesh92]

Suprb bro...

[@md.ragibahsan9583]

Is that the CDI are all the same or it varies to various engine (like 125cc, 150 cc or 250cc) ??? Because i have a problem of CDI, i have lost my 250 cc motorcycle CDI (8pin), but in the market only found CDI s which have no specification about engine? is there any problem if i put any types of 8 pin CDI to may motorcycle? Plz help me,,,, Thank u..

[@niacaraga6997]

good day! how to determine/test to check whether the CDI is AC or DC? thanks.

[@greatking1327]

Thanks a ton!

[@Hsenag87]

Can u plz explain how to remove speed limit on ac cdi. Which part need to bypass on circuit board.

[@andres2164]

So the negative side of the capacitor is connected to ground? on the generator?

[@Ducktruckful]

Hi Great job! is there anyway to check voltage going to coil + from cdi box? I never hear anyone explain that. Or is it a MF you can't test without a scope? Just wandering........

[@abdullahalluman7450]

One thing is needed to be cleared. Just after the compression stroke, when capacitor discharges current through the triggered (Closed Circuit) SCR, is that current AC or DC? My concept says that the discharge from the capacitor must have to be AC. Because if the discharges from the capacitor is not AC then there will be no changing flux hence there will be no induced current in the secondary coil.

[@Dr.AmitMandal]

its varying dc , that can also drive the transformer..

[@shahrukh6802]

Sir I what didn't understand is that when magnet rotates a cycle around stator coil, also pickup coil trigers in one cycle, which completes two strokes. So in this way triggers should send signal to the SCR two times in 4 stroke cycle.

[@hajiclub]

great!

[@BiplabMahata_]

Thanks for this informative video. I hv a question, that is.... Approx How much voltage generated in trigger coil??? I hv a RE TB, my rpm meter was gone last year. Now i want to set a arduino based rmp meter. For that reason when i checked the voltage of "pulse wire" of CDI, I found only fluctuations of about 0 to 160/170mV during acceleration through a digital multimeter. Is it normal????? Please help me about that for better understanding. Thanks I want to know that how many voltage can i read through a multimeter in pulse wire of CDI???

[@thotasaikumar4293]

Great explanation. What type of diode can be used in this type of system? What is the Range of diode?

[@Dr.AmitMandal]

Electronic part, can't say anything about that.

[@thotasaikumar4293]

@@Dr.AmitMandal thank you

[@LongDefiant]

Thank you, well done.

[@viswanathaniyer2372]

good viedeo

[@sachinramesh1540]

excellent explanation

[@pravinpradhan2394]

Sir please make video on Transistor Controlled Igniter (TDI)

[@oppanheimer]

The spark is generated when the magnetic filed in the secondary coil collapses(i.e., when the SCR switches off).

[@Dr.AmitMandal]

yes

[@adityarasal2187]

Is this contactless type of ignition ?

[@Dr.AmitMandal]

Ya

[@himirkantisarkar6340]

best👍

[@misterjack347]

i was told that only ac current can be stepped up using coils or transformer, but here i think dc current is being stepped up? isn't it??

[@Dr.AmitMandal]

Pulsating DC also works with transformer

[@adithyadevadiga437]

👍👍👍👍👍

[@raymondgarafano8604]

O.K. I guess the exciter gen produces enuf volts an current to work ign. coil when trigger coil works the scr,

[@ranadems]

In a four stroke cycle IC engine there will be a spark at the end of Exhaust stroke as well. It is called as a waste spark. Suction and Compression is a one rotation of the crank, Spark will be ignited by a Hall sensor at the end of the compression stroke. similarly Power and Exhaust is a second rotation and a spark will be triggered at the end of exhaust stroke.
