Why Do Modern Cars Use Direct Fuel Injection? Fuel Injection Series Part 2

[@perniciouspete4986]

Yes, more educational stuff, please! It makes us all better DIY'ers.

[@d.davis2009]

Your flair for explaining this is only out weighed by your analogies and your bright personality and knowledge of the subject. Great Job

[@perniciouspete4986]

Explaining something simply requires understanding it thoroughly. Kudos to TCCN.

[@stormcrowe9820]

+1,000!

[@dougrobinson8602]

@@perniciouspete4986 I've often said that if you can't explain something to a person with no background in that area, you probably don't understand it that well yourself.

[@abrecos]

My friend 40% of videos I watched on KZbin it's your channel. I absolutely love everything that you does, you are very well educated and spoken person, very humble and compassionate and professional at least. I truly appreciate your hard work and passion you put into your videos. God bless you and your family!

[@JamesCarter44]

I’ve never seen someone explain car parts as clearly as you do. Not just what they do, but actually how they do it and the design principles used. Please keep this series going. For people with no mechanical background or other resources to rely on this is extremely helpful.

[@AWKdF]

From a 68 year old who grew up working on 60's and 70's cars. Owning a 2000 Tacoma and it's got injectors that were replaced a few years ago, I need this kind of learning for the Wife's 2016. Give us more.

[@meandivergence]

As a life-long student of all things learning, please continue to educate us with all of your infinite wisdom!

[@abrams313]

Hi Mr. Car Care Nut. YES. More please....and god bless you, your family and your whole team!

[@stavroscambanis9576]

We certainly do want more educational stuff!!! Knowledge is power!

[@gordo3040]

You are my college professor teaching me hi tech info. My 2020 RAV4 XLE with your great description of the D4S system is running great with over 54k miles, and I have never had a check engine warning yet. God is blessing you for your great educational videos. Keep up the good work.

[@user-tb7rn1il3q]

Same here with my 19 RAV4 LE AWD at 131k miles, knock on wood. This car is literally a maintenance free tank. Still on original everything except for tires, wipers, oil, washer fluid, and filters. I’m on the second set of tires and they are less than half worn with 90k miles. I broke a belt in the original tires carrying over a ton in the back.

[@Dryloch]

My friend has a 2020 CRV. He has had manly issues unfortunately.

[@بلبلرايدمشاكل]

Please make a series about everything works in a car and how it started this is really educational

[@ragabnh]

Hello Ahmed I have 21 LC 500 with Dynamic Handling Package and 17 LX 570 fully optioned as well. I am a car guy, I have some knowledge about how cars work and used to do some on my cars when I was younger. I learned a lot from you and really enjoy watching your videos and look forward to new ones. Thanks for educational information you gift us.

[@000distructzero]

Although you have a wealth of knowledge and skill with these vehicles you're able to explain the basics in a non condescending way. I never feel in these videos I'm being talked down to. Many of the jobs are obviously not DIY, but it's still beneficial to know the basics of how the systems work and why they were designed the way they were. I own 3 Toyota vehicles and the more I understand about them the better. Please more in depth videos, I'm here for all of it.

[@fishyjoe6470]

I agree - if you know how the system works, even if it's not a DIY fix, at least you have a chance of being able to tell whether your mechanic is being honest or not

[@romannikolayev201]

Please, keep on making this educational videos. They're very useful. There are so many different systems in modern cars, that need to be explained.

[@ihorhavryliuk7964]

I wanted to understand how direct direct fuel injection works for a long time and here you with your beautiful explanation and illustrations. That was very informative for me. And YES for more educational videos like these ones. Thank a lot.

[@user-kh6ug7ow4o]

Definitively needs more on these….As a worker in emissions control industry of catalyst, canning and sensors, I’m so surprised that you can transfer those specific terms of technical words into common languages that most people can understand. This is just a beautiful thing.

[@zmy350]

This is when you know you have an excellent tech/mechanic. Your thought process is very methodical and not only can you resolve an issue, you understand why and how it happened. Great job?

[@WA2AMX]

Please continue this series, many aspects of modern car systems need this coverage.

[@praetorian5499]

I love this series and types of videos. I was having cylinder 5 misfire code and injector circuit / open code on my 2002 Chrysler Concorde 2.7. Replaced fuel injectors this morning and it’s running great now.

[@MimicMan0324]

I've learned so much from all of your videos! Thank you.

[@samh6761]

Excellent analogy of long vs short fuel trim. And your D4S explanation... what an amazing system! I thought it was just about cleaning the carbon off the intake port, but it does so much more.

[@raycollington4310]

Not only is it great to educate us, you’re a great ambassador for the automotive technician industry being so much more that grease and oil. The breadth of knowledge here is best in class. There will be a lot of mechanics learning loads here. You’ve given them the tools to explain all this to the customer and enhance their image. Computer control areas is an interesting subject. Thank you all at TCCN

[@armchairtin-kicker503]

Currently owning a 2008 Lexus GS 350, previously owned a 2007 until it was rear-ended, I agree: the 2GR-FSE is a beautiful yet powerful engine.

[@luciancretu4905]

Yes, develop the series, no question about it. Beside the fact that these kind of videos will most certainly help diagnosing issues, it is fascinating to learn these systems from their grass roots. Moreover, the analogies were great and really drove the point home. I will say this: this kind of video may not get the most views, but will most certainly get the most appreciation from the community. And I will not skip the ads :)

[@EvzenKovar-i5p]

I have actually been looking for a really good explanation of fuel trim over the last week. It’s one of the parameters I can view with my recently purchased scan tool. Your explanation made perfect sense. Now I really know what I’m looking at. Thank you CCN!

[@SignorLuigi]

More of these car system education videos, please! I know they must take a lot of work to prepare. But they are SO WORTH IT!!!

[@tomschmidt381]

Great tutorial about fuel injection in general and specifically direct injection. As a retired engineer (electronic not automotive) I enjoy these deep dives and you are able to strike the right balance in helping folks understand the technology. The more the better.

[@shengruizhang6476]

Absolutely love this series. Starting from the history, slowly walking through each stage of the technology. This is the best way of learning IMO

[@kkeshav74]

My 07 IS350 with D4-S continues to run strong! And I always do WOT pulls when it's fully warmed up very often 🔥 Please make more educational videos!

[@bobcook8576]

I love your passion for the automobile. Your excitement for what most consider mundane is remarkable and passionate. Your channel has grown exponentially because of your desire to spread your knowledge. I'm not a Toyota guy, but I know when someone is dedicated to their craft. I subbed after watching your first video.

[@fr9039]

I love the educational content, but I also love the procedural repair videos. More of both types would be great! Thank you for all of your efforts. Given today's realities of high-priced parts and expensive labor charges, the information you provide us is literally worth its weight in gold :)

[@petertarantelli]

The ICE is an amazing piece of engineering in its own right and your thorough explanation of the fuel injection system is very thought provoking.

[@TripleBerg]

Great explanation of dual port systems. I never realized how sophisticated they are. Thanks

[@nurmworks-4284]

Please do more of this. You really do have a knack for explaining this stuff in a way that is quite relatable and always seems to give me one of those aha moments. Regardless of the complexity. Your analogies only further that understanding. Thanks!

[@bdaneau]

Keep these coming AMD - as an engineer, I can assure you that your explanations are much easier to grasp than those I got from various profs in engineering classes I took a long time ago. And the dog leash analogy for short term / long term fuel trim was simply perfect !

[@ChristianGuevara-m1d]

Iam a 23 year old technician and I learn a lot from these videos, I would love to learn more to advance my career.

[@turkeyssr]

This was a great series. Thank you!

[@midiman5045]

Yes, Please more of the educational stuff. I am so glad you told the amazing thing about the DS4 at cold and the mixture ratio being so precise. I know it was a great engine and that is why I chose it in my current Lexus 2022 RX-350 . Have had a 2019 RDX A Spec which was a total disappointment in city MPG and display issues. and build quality, The RX 350 has met every expectation. Keep up the great videos AMD we all appreciate it.

[@mikehenry2116]

Keep doing videos like this and all the ones before. Your way of explaining how things evolved and work makes it all very comprehensible. You are an excellent instructor!

[@randydiaz5951]

Yes, keep it up with the nice series of how car systems actually work to make them run as refined as they do nowadays. Thanks so much, Ahmed! Once again I’m proud of the Toyota brand and their engineers, they’ve done such an amazing discovery as well as their hybrid system over the time. So amazing Toyota!

[@ttuck9603]

Enjoy the educational series!!! It provides a nice mix with your repair and vehicle review videos!

[@Tom-ej8bb]

Had a 2022 CRV but traded in this spring for a 2024 RAV4. RAV4 was not available due to $ gouging. I am a long termer. We still have our fantastic 05 accord!👍 I specifically wanted the RAV4 because of the direct AND PORT injection D4S system and NO Turbo!! Couldn’t be happier! Car review people don’t even mention the importance of this especially if you are a long termer!! Ty again!!

[@alfontana6242]

We have a 2020 Toyota Highlander, hybrid all-wheel-drive. This is a 2.5 L dynamic force engine and has port fuel ejection along with direct fuel injection. Thanks for explaining why we need both. I had no idea that they both work together for maximum fuel efficiency. Thanks again for explaining that in simple terms that even I can understand.

[@carlredmond3642]

Yes, more like this please. It's really educational and interesting. Great explanations. Better than a college professor.

[@JJF1973]

AMD, killing it as usual! Bravo!

[@erginyilmaztenor]

Hi from Turkey. Thanks for this series. I love these types of videos coming from you guys. Can't wait to see something about the Toyota Ecvt transmission.

The SC300 and the Crown 👑 in the back! 🤤 I had a 96 SC300 2JZ-GE with 496,xxx miles! Unfortunately a drunk lady crashed into me and totaled it. I love your videos! Super smart man!

[@azclaimjumper]

I'm going to have to watch this video several more times B4 my mind can wrap itself around everything mentioned. Thank you.

[@crooney82]

Car engineers are amazing people. Trustworthy experienced knowledgeable mechanics are also amazing people.

[@LandyPR27]

I would love to see more technical videos like this one. It brings back memories of when I was studying automotive technology, you really sounded like one of my proffesors that explain everything in a simple manner. Thanks for the awesome video. Keep it up. Blessings! Watching from Puerto Rico

[@franciscor1988]

I just love your channel but also the fact that you look like such a good person. I find these technical videos extremely useful and interesting. Although I am not a mechanic and English is not my mother tonge, I am nevertheless able to follow your explanations. That, I would say, speaks volumens of how good you are at teaching. Thanks for all the videos. I enjoy a lot watching them. God bless you too

[@OttoGyuris]

Here is another positive feedback. I am a big fan of your channel and these type of honest videos as well. It is awesome to learn about your point of view and Toyota quality. 🙂 I have a suggestion as well, but this might outside of the scope of this channel: sometime the best thing is to learn from failures. I know your shop is busy, and content creation takes so much time. Why don't you catch a random failed/destroyed/faulty engine from a junkyard and tear down it to parts sometime. In this case you can save some time because garbage is garbage but the investigation of the original root cause (and previous owner's mistakes) might worth the effort. Anyway, thank you for this channel and wish you all the best!

[@meanodustino9563]

Doing my level 3 apprenticeship and fuel systems are for the week. Yikes. Lots to know and GDI is today and tomorrows topics. This is perfect. As a up coming Toyota tech as well, Thanks explaination so hope i understand what professor is explaining

[@jasonneugebauer5310]

Toyota duel injection is the state of the art system. It's much better than direct injection only systems. What will car manufacturers do next to meet fuel economy standards? Will cars get lighter and more aerodynamic, or will Americans continue to drive heavy blocky SUVs and pickups in their daily commute? I love th3 info4ative educational videos. Please continue. 😊

[@rickb296]

Carburettor is a "giant dribble box". Love it. Great explanations AMD. Superb video.

[@MarkSmith-js2pu]

This is quality stuff. AMD👍❤️

[@zacharia63]

Sure buddy, pl come out with such technologies used in automobiles now. Not necessarily from Toyota alone, but from any manufacturer or inventor. Thanks for such exciting episodes man!

[@NMTRUCKER]

It’s a great explanation of direct fuel injection but I have to congratulate the engineers and scientists who developed this technology for the masses. Well done. 👍

[@journeymancellist9247]

I noticed that he uses terms I don’t understand. What is a cylinder head, or a manifold, and so on. He assumes we already know what these are. Sorry, pal… but I went and looked them all up, and now I understand his videos. So he has inspired me to learn more on my own, and I understand him better. I will take very good care of my Subaru and it will outlive me.

[@markmcentire3111]

Please keep the series coming! I love engineering and learning how things work.

[@user-uq7io2os3r]

Part2 is a must for any younger car enthusiast 👍 great explanation of very complex design, process I'm sure I won't be alone asking for more similar technical explanation, educational videos from our beloved team 👍

[@lalouise5478]

This video is even better thn P1. Thanks man.

[@randywilliams5337]

Your explainers are very good and understandable. I haven't had a Toyota in a long time. But now have a'23 4runner because it's old school. Now thinking of something for my wife. Im looking at the engines and transmissions. so dual injection and the ecvt seems to be the way to go. I saw an explainer on another channel that was made years ago on the Toyota ecvt and it was fantastic. It was all apart and he put it all back together again while he explained how it all worked.. Thanks for all the great information..

[@WilliamCloud9]

Yasss!! More of this tech/educational content sir. AMD you have some of the best content out there for me anyways

[@chakibElIdrissi]

The explanation was crystal clear. I learned something today. The two systems working together was very enlightening

[@micah3532]

Yes please do make more series like this; thank you for all your time and work you put into your educational and interesting videos

[@JaroRebel]

This is an excellent tutorial. I thoroughly enjoy the way you explain how things work in the car. Keep them coming please.

[@mikeporter2126]

Yes. I would love to see more of this series. Great job explaining how systems work!

[@appalachie]

That's very reassuring about D4S. My wife's 2022 Lexus RX350 has a 2GR-FKS engine, and I was leery of the extra complication & reliability risks of dual fuel systems. But apparently Toyota has refined D4S for ~20 years and probably have thoroughly "nailed it", just like their hybrid technology. I'm also thankful that Toyota/Lexus don't need obnoxious "automatic start/stop " or cylinder deactivation gimmicks to achieve gov't mandates. Nevertheless, I am conservative regarding daily driver cars & their reliability, and given a choice, I'd have been happier with just port-injection alone, even if does give up some efficiency & power.

[@kimbuck-2]

Good morning all!

[@riceburner4747]

👋

[@michaelmounts1269]

Another absolutely excellent video---One comment--I wouldn't ever buy a car with only Direct Injection. I've seen the carbon on Audi/VW products--it's horrible. Partial answer is a "catch can"--but adding one yourself would void warranty. One MB exec told me they don't do catch cans at oem level because consumers would forget to empty them and really mess things up. The Toyota system is an excellent compromise...

[@wrbrower]

More similar videos, please. Even though I am no longer a Lexus owner, I still follow the channel.

[@yournightmare9999]

That's great because toyota and lexus is way worse today less reliable

[@peterkwok9608]

Aloha from the 808, hope everyone has a blessed day 🙏

[@tubbysomis]

Excellent work and much appreciated! Yes, please add more educational content on vehicle systems. This piece was informative and very helpful as you explained ST and LT fuel trims. Your analogies about the dog and leash made sense to me. Enough so, that I have a rough understanding of ST and LT for the first time. I would also like to suggest a piece on emissions readiness and how that impacts those of us in states with mandatory testing. I disconnected the battery in my 2014 ES350 right before I had a smog check and am now waiting for the various readiness systems to function so I can get my biennial smog test completed.

[@kevinmorales6666]
