These are the best explanations of hybrid systems I've seen on UA-cam
Thank you Professor for putting videos up on UA-cam. They are excellent quality and you do a great job. I'm a former Navy jet Tech and enjoy repairing my own vehicles to factory spec. Watching this and the battery videos, and accessing AllData will assist in a project I'm doing to swap engines for a Hybrid Civic for my daughter's first car. Again, great job and can't wait to watch others!
Fantastic video, I’m just starting my EV / Hybrid journey, I’m no spring chicken ( old dog learning new tricks ) and really appreciate you taking time to share you knowledge
Hi, do you know the speed for this motor and how manny Hz have this motor?
I always appreciate your very clear and precise information included videos and your arduous job. Those are very helpful and valuable for us. Thank you very much dear Professor, John D. Kelly !
Your videos help me so much! I watch your videos instead after work (I also work in a shop). Thank you! And who ever thumbed down... clearly your not ready. That's okay. One day maybe
Thank you!
You are a great instructor! Hybrids look like an interesting system to work on by someone detail oriented and knowledgeable in electronic systems. Not a system I'd want a hack working on!!
Thank you!
@@WeberAuto Hi, that drive spline that can strip is that a problem which can occur on the non hybrid drive CVT transmission cars?
Thanks for sharing your professional guidance on I.M.A. stator and rotor services
You are welcome! Thank you for watching
Thank you, Professor! Now I understand the main differences between this single electric motor hybrid system, and the two electric motors that Toyota and Ford have. The two motor system takes advantage of the planetary gear set, so one motor is the starter/generator/assist and the second motor can drive the main wheels in parallel as the planetary set allows two power inputs and one output. This is why the Toyota/Ford systems work much better.
I wonder if the IMA system can add a clutch between the rotor and the crankshaft to isolate the electric motor and avoid turning the gas engine until it is started. Th electric motor will have less loading and obtain more range.
Thank you! The new Ford IMA hybrid type hybrids use a clutch between the crankshaft and the rotor for EV mode
Another outstanding video, thank you. This really highlights just how advanced the Toyota system really is.
Wow, what a pleasure for the tutorial on my Honda.. !!
Thanks for watching
Very well presented & informative. Atkinson ICE then IMA followed by a CVT, you don't want to be around when that lot hits harmonic resonance.
lol
Спасибо за подробный рассказ. Очень понравились гараж и инструменты.
Спасибо
Glad to accept your subject
Fantastic, detailed instruction. Thank you.
Thank you!
There were/ are manual transmission option for the IMA/ Engine combo on Honda vehicles, like the 2010-15MY CRz :: FYI
There is a way of explaining IMA that I find useful to petro-nuts
The IMA motor generator provides 10kw/ 13 hp of electric boost & torque while the gasoline engine is spooling up to a useful RPM range
The IMA motor can extract or recover energy from the drivetrain to charge the energy storage battery (traction hybrid battery)
Later models use a 15kw / 20 hp IMA motor with greater e-boost & energy recovery power
With peak torque between 1000 & 2000 RPM the electric IMA motor is strong when the petrol engine is weak.
This gives the 1.5L engine setup in the 2014 CRz that I drive better than Diesel like low end torque performance, where you can tool around at low speeds in 4th, 5th or 6th gear as you approach 30mph, the engine barely spinning at near idle speeds. If you are really gentle with the manual tranny, you can eeek out 40+ MPG
@@WeberAuto hey! Thanks for the vid. I'm replacing the rear main seal in my 2004 Honda civic hybrid. Can I just remove the entire hybrid assembly without removing the rotor separately to access the back of the motor? I'm trying to avoid buying/finding the rotor removal tool. Thanks!
Thank you professor john❤️
I love your research! you are amazing man! Keep going!
thanks for your video about the Honda hybrid IMA system. Really great for your teaching skill. great job sir
Thank you!
Excellent, thanks!
Fascinating. And, of course, wonderfully presented. Thank you for sharing.
Thank you!
Thank you for sharing your knowledge and experience.
Very valuable information.
Thank you!
I love the way you are explaining everything, thanks very good job.
PEACE!This site has indeed been impactful
.
Thank you
realy nice to see whats in my car , thanks
Awesome explanation of how these systems work! Loved the special puller explanations as well! Thank you :)
Thank you!
You did a good job explaining how many different automakers are doing different kinds of electric motor integration with the ICE to improve fuel economy, lower emissions and make more useful torque sooner while also enabling energy capture from the transaxel to charge the hybrid battery (regenerative braking + peak shaving where the crank energy available exceeds the user input demand (pedal request) to capture excess energy from the engine that would normally go underutilized in a conventional vehicle.
The spline shaft rusting problem you identified clearly articulates why keeping water out of a vehicle made with IRON & copper based components is so important! Those reactive metals undergo entropy faster with ongoing exposure to water.
Any thoughts about the best hybrid architecture, system complexity vs reliability and net long term carbon energy or total lifecycle carbon of each system approach. It is possible to make a wildly efficient system that is not very reliable, but very costly to make as one example.
What about hour meters, and why automakers do not include hour meters on vehicles? so you can see how many net hours the vehicle has been on?
Any thoughts about the battery longevity in hybrid vehicles, in terms of calendar years ? replacement costs ? and long term access to replacement parts as the vehicles age?
Thank you! The newest Toyota hybrid system is hard to beat. The only thing I was hoping they would have done was to use gasoline direct injection on the Prius. The new Camry hybrid with GDI is almost at Prius mpg. If the Prius used GDI, it would probably be above 65 mpg. GDI is expensive and troublesome though.
No thoughts on an hour meter. Some on-board ECM track engine run time.
Honda seems to be the only hybrid manufacturer with terrible batteries. Nissan isn't any better with their leaf EV.
Thanks for your feedback!
Continues seen p1,2,3 thanks for your every expensive word's
Profesor Kelly....eres el mejor!!! Saludos desde República dominicana.
Thank you very much for this very informative video on honda IMA
Professor you are really pro...thank you so much for your videos
Firstly I have to say thanks a lot for your explanation it’s well done.
Thank you!
This Technician is Amazing 💥🇺🇲
Very wide knowledge. Thank you professor.
awesome breakdown of the differences between the 2 generations! #brainwrinkled
Great video. I'm trying to help a friend diagnose a problem with his 07 civic hybrid. When he gently accelerates from a stop there is a chattering noise then it catches. Letting off of the gad helps. Only occurs from a stop not while driving. I'm by no means a professional, but I've for many years worked on my on vehicle and friends however I've never worked on a hybrid. I'm trying to learn as much as possible and this video series was very informative. If anyone has a direction to point me I'd appreciate it. Thanks for the help.
Thank you
Well done. Very clear presentation and demo. Thanks.
Great job.....Thanks for such a knowledgeable sessions
Thank you!
WELL DETAILED..
Thank you very much
Again another show of explanation. Congratulation.
I am very impressed with your presentations I got strides with th Prius series I like to know how things work happy to find the Honda youtube today thankyou very much Dale Janssen Arizona
Wow! Super nice and intristing
I found your channel extremely interesting to me!
Thank you
Best video about IMA.
Could you advise the commons reasons, why 12v battery unable to charge from IMA HV battery?
Fantastic series sir , very informative and well explained. I also have to say , along with your explanation you showed us the internal workings and a bit of how to test them as well. Looking forward to seeing your other videos and I subscribed..well done thanks again.
Thank you!
You are a blessing for us for sure. Thank you and please keep up the great work!!!
As a massive fan of my old first gen '04' civic ima manual, i am wondering if you can change the 10kw ima engine with a later 15kw ima engine. In the video they seem to be the same size🤔
Thanks for the information on the IMA system. I was thinking Hyundai has a clutch between the crank shaft and their IMA motor so the engine and the motor can be decoupled during electric mode only.
Thank you!
Fantastic explanations. I've been afraid of digging into my Gen 1 machinery (I'm very comfortable tearing into IC engines), but you've made it so clear that I feel confident that I can do it if necessary.
Question: Is it possible to swap in a Gen 2 stator assembly and add a few cells to the battery to get that 50% increase in power?
Thanks!
I am not the professional but have some experience in hack upgrades. My guess would be you would need to replace the rotor, stator assembly, wiring to battery, and battery unit (including the modules as the charge voltage will be different.) Whether or not the 2nd gen control module would play nice with the first gen engine ECU is a different story. Also you might run into issues with the different speed sensors present and swapped with the stator assembly since I believe at least one of them goes to the engine ECU and even if the connector was repinned it might not have the same input voltage or wave pattern. Sounds like it would be a pretty big upgrade if it works!
Thank you for this video one of the best out there !
Excellent..!!!!
Thank you
That is very interesting hybrid
thank you for your efforts ...
Thank you!
Do a teardown video about the hyundai ioniq hybrid starter generator.
I wish I had the parts to do a video on them. It looks like an interesting system.
@@WeberAuto I believe Hyundai used Dual Clutch Transmission on its newest hybrid. That's what I am afraid of, just like Belt-type CVT in Honda. They are not known for reliability.
Thank you professor !
Great insight and very helpful, thanks.
Thanks! 👍👍👍👍
Thank you!
Can the U V W wires from the generator be desired some other way regulating the voltage so that it can run the car without the IMA battery? After all it is a generator that isn’t being used after the IMA battery dies
you do that really well sir
Sir Thank you for your professional training. We have lot of problem with Honda Earth dream Technology i-DCD dual clutch transmission can you do a training program on this
Thank you! I would like to get my hands on one of those transmissions. Best wishes
Awesome explaining?
Can you replace the old style stator with the new style?
Thank You so Much.
Great Teacher !!!
Thank you!

John, does not the magnet ruin your watch and phone. I used to work with NMR (MRI version that is used for chemical samples) and on a number of occasions they ruined my bank cards.
Excellent videos. My problem is the IMA light comes on and also the IMA Battery fan,this problem is intermittent, any idears.????
It sounds like your IMA battery is either running hot because of a blocked intake duct or fan problem, or the IMA a battery is going bad
I love these videos, keep up the good work! Can I request that we see a teardown of the newer style Honda hybrid system used in the 2014-current generation Accords?
Thanks for the info. Doing your EV course now.
Question: Can you swap stators between generations to get more power on older civics?
Thank you for all the material, it's brilliant! Why the hell don't they crank the engine with the IMA and rely on a traditional starter motor?
Redundancy. The car can operate entirely in petrol mode in case the hybrid system goes belly up.
Also, in very cold weather, the lead acid battery is better at supplying the necessary current to start the engine than the NiMH battery. Indeed, a lead acid battery's ability to immediately output massive current in all conditions is the main reason they've stuck around so long.
Take apart the 6 speed manual CR-Z!
Super!!!
Thank you!
Perfect info..!!! Congrats!!
I like your microphone system !!
(Brand Model ) Please..!
Thank you, I use the Sennheiser ME3-EW microphone connected to a Sennheiser EW100 G3 transmitter and receiver
Any chance of volvo v60 d6 phev with isg bolt on tech. Or even better, xc90 T8 phev explained. Their ERAD tech is pretty interesting
I will have to check it out. Thanks for the suggestion.
Hi i have hondacivic 2007.and not charging 12 volt bettry ima and engine lights on always don't wats up i check all fuse boxes
Probably a bad IMA battery. Best wishes
@@WeberAuto thanks
fantastic video, great instructions and for a dyi type its a must have, i need to replace my resolver sensor on a 2008 civic hybrid, i thought id see the sensor removal on your video but sadly didnt. any way you have some insight on it, thanks and keep doing a phenomenal job
Thank you! The resolver is in the stator housing. It is easy to change once you remove the housing. Best wishes!
Thanks for replying, 1 more question, I have the pdf that explain how to replace it, but also says it needs to be calibrated once replaced, what if I don't have the HDS to calibrate,
good
Most definitely the best videos I've seen on Honda's hybrid systems. Question, I have a 2006 Honda civic hybrid that I had just recently got 3 recalls done (one being the DC DC converter being replaced) but I am still getting a rotor motor position sensor fault code error. Do you have any ideas on where I should start to try and solve this issue or what could be causing it to throw this code? Thanks in advance
That's good video.
I have a question why do we have 3 speed sensor over IMA
What about the IMA system with a manual transmission (CRZ 6MT)?
Rotation calibration possible from phase current without sensor
Hi I have a 2009 civic hybrid with the dtc POA3F. Motor rotor position sensor. I didn’t see the motor rotor position sensor for the 3rd gens and what else you can tell us about this error code. Can we do it ourselves or does Honda need to replace it.
Hi WebberAuto, I've got a Honda CRZ 2013 which is lithium ion battery, my question is if you were to take of the Motor and stator would you be able to wrap bigger copper wires and how would that effect the operation of the system? All the best, thanks for your videos regarding IMA they are really enlightening and will help with servicing my vehicle down the line.
I'm replacing the engine, can I take the electric motor out without taking it off piece by piece, the engine is bad but everything else works, and Would rather not take extra steps, thanks
Anyone know if a gen 2 stator can be swapped into a gen 1 Insight for extra power? Hole pattern looks the same, just have to splice the right HV connectors maybe?
I have to replace the rear main seal in my 2004 Honda civic. Can I just remove the entire housing along with the rotor/stator to access the back of the motor? I'm trying to avoid having to buy/find that special rotor removal tool.
Sir may I ask my Honda insight 2010 no paddle shifters .
Can I just installed paddle shifters by connect to use ?
On the first generation Honda Insight electric motor. Please explain what is happening when the electric motor is generating electricity by slowing the car down.what is the electric motor doing while slowing the car down and producing electricity. Does the increased magnetic field slow the car down through magnetic field resistance. Or something spinning faster and rotational mass slows the car down.
Do you know if the stators use NEO N52 magnets?
can i follow these steps on a 2006 honda civic hybrid or does the IMA motor/rotor completely change?
Same steps for the 2006
If you replace the commutation sensor is there any special instructions? I replaced mine and now it doesn’t start
Sir. I have a question
in Honda hybrid gp1 ima engine . In one cylinder two plugs have littel oil drop
Why is that?
what is the solution for this ?
There are several things that can cause that problem, none of them have to do with the IMA system. I would do a compression test and a cylinder leakage test.
Normally in civic's with this engine. The valve cover gasket and spark plug tube seals leak oil. Over time if not fixed this can cause damage to the coil packs and cause a misfire.
I just replaced my IMA battery in a 2009 civic 170,000 miles. Is it common when the battery drops below half to have a hard time charging back up.
Yes, very common on Honda IMA systems
before 2012 yes. before lithium-ion batteries were installed. in the Hondas anyways. the 2003 to 2011 Ni-Mh batteries were more difficult to keep charged properly and if are allowed to sit at low charge states for a period of time and often then they are much more failure prone. needed to drive them longer distances if primarily drove them in town in order to keep them charged and in/at a higher charge state/level. in 2012-up with the Li-Ion batteries they didnt have as much of a failure rate, or were not as easily damaged by being in a lower charge state.
Thank you Professor! I have a question for you. I have an Hyundai Ioniq HEV, which It has an electric motor between ICE and gearbox, a dual clutch transmission. This model, which i don´t know if it sells in the U.S. uses the same hybrid system than Sonata Hybrid. It can runs at electric only mode for 2 or 3 kilometers at speeds up to 120 kph in certain conditions. My questión is, if you know, is there some kind of clutch that "disconnect" the electric motor from the engine? or is it solidary to cranckshaft like Honda's system? Thank you :)
I believe I read that there is a disconnect clutch or one-way clutch between the crankshaft and the IMA motor on that model.
@@WeberAuto I have been investigating a bit. In the end, it's easier than i'd thought. The dual clutch connects the electric motor and the transmissión. And a third clutch connects engine and electric motor. I've found this diagram: www.hyundaipartsdeal.com/parts-list/2018-hyundai-ioniq-hybrid/clutch-release-fork.html.
Thank you for your answer and i hope that mine would be useful for you
Hi professor. If my Honda Civic 2012 shows up the IMA Light and Check Battery Light in the dashboard.... And de code is P1440, what would be the error?
Hey doc thanks for the knowledge I wanted to ask a question about my 03 hybrid honda civic can you drive it with the IMA battery being turned off because the battery is dead so is it possible to run it with just the 12v
No. The 12V battery will die as you drive and it will shut off the engine.
If there is an issue with this, would it cause the car to vibrate and make some noise when accelerating from a stop position? I have a 2006 Honda Civic Hybrid CVT transmission. Been having some vibration/juttering sensations when pushing on the gas pedal from a stop position. Its worse on a stop position if on a hill/incline. It only does this for a few seconds then stops as i gain speed. But its very noticeable
Hello Sir,
My question isThe 2nd gen hybrid battery has 158 volts in the cells, but I noticed the Ca2 type has around 168 volts. Do you know why?
Thanks in advance.
Where can I buy or rent the rotor removal tool? I've googled it and cannot find a source.. thanks, John
Sir, can you please confirm:
What instruct IMA motor to sense that on what RPM & TORQUE motor should rotate (Contribute to Engine's Load)?
I have a specific question about an 03 civic hybrid: when rolling forward from a stop I get this groaning noise from under the front of the car. It isn’t when turning, just at that initial startup phase from a red light or something similar. Any ideas on what that sound could be?
It is hard to say, but the flywheel splines are known for rusting and slipping at times. Eventually it prevents the vehicle from moving.
WeberAuto hmm I imagine that could make that noise if it did; cause a grinding sound. Sounds expensive. Thanks for the input!
By the way; great video and explanation.
so are these brushless dc motors or are they a.c.?
Mr John,quick question....i'm working on a small project,trying to design my own engine-can u explain to me any disadvantages using the IMA design but the stator will be powered and the rotor magnetic,thanks!
