Diesel Engines 101. Class 2. 

Anyone else automatically like when video first start cause you already know it's gonna be good lol

I'm a 27 year mechanic, this free education is better than any school you'd go to and pay for it for 15 years, good job sir and thanks for helping people.

You are literally the very idea that I envisioned online videos to be used for as an alternative to college courses. I hope that you have seen prosperity both financially and spiritually because of this. Knowledge is the basis for opportunity and evolution. And you gave it for free. Thank you. Too deep? Maybe so. 🤣

The way you thoroughly dissected the topic , in order , in simple terms and in 25 minutes is incredible. I just want to say thank you 🙏🏽

I'm a mechanic with 20 years of experience, but I'm looking anyway! Great explained !!! :) :) :)

Just wanted to say that your channel is one of many things that made me want to become a "diesel mechanic", so now I'm at a company working on Scania buses, some Volvos too. This is in Sweden so no peterbuilt or CAT really

Being a diesel mechanic is easy because they never break. They never break because the parts are bigger. More robust.

Absolutely beautifully made. Thank yoy

Love the video better yet all your videos!! I’m excited that you started this series and the way you make things so simple to understand. However that was the quickest 23 minutes of my life and am sad it’s done 😢. Can’t wait for the next installment, keep up the great work!

Another great installment! Can't wait for the next one.

Thank you man you make me understand stuff that I don’t in school!

Excellent presentation...Been in a lot of classes over the years, you'd make a great instructor. It's one thing to be able to work on it, but to be able to explain it is another skill. Appreciate the time you put into this!

Awwe no destruction of the week 💔

This is a great beginner series. Will you be making a master mechanic series?

I'm in the Philippines, middle of nowhere and recently bought a 6KW diesel genset; there is no-one in this area that works on diesel engines because the majority of vehicles and gens run on gas. So I need to get on the learning curve in terms of maintenance and rectification. I love the pace and delivery of this course, well done for a good job!

My C15 is in the shop now for worn valves. Scheduled an overhead adjustment, couldn't get the feelers under the rocker properly, which lets you know the valve stem was too high! Could have been bad if wasn't caught. Thanks for the video!

I'm at the point I can tear down a c15 and rebuilt it in 23 minutes with this man's tutorials great explanation 👍 on all your uploads keep it up

I figured this out changing valve stem seals on a Mercedes OM617- great example of a simple and iconic diesel engine design.

Wow, best of best , taking notes on real note book. Spreading sharing knowledge is like giving actual money and Josh you gave me at least 2000 dollars or more , I saved that much money by working on my C15 , thanks a lot

Thank you so much. You are a natural teacher. Someone like you should be highly paid teaching future diesel mechanics

Thanks for sharing your vast knowledge on diesel engines. This will help me provide for my family in the future

Thank you Josh for another wonderful diesel engine video. Great job sir, TMP from N.J.

Thank you I’m 12 and my dad is a like decile mechanic and a farmer so he doesn’t have a lot of time to teach me can just show and my older sister is a airplane mechanic so I feel I have to be a mechanic and I enjoy mechanic work so thank you

Really like how you explain everything so clearly and with pictures and actual parts. Learning so much 🤙🏼 Onto the next vid

If I had teachers like you I wouldn't have dropped out of high school

Was this filmed at home? I swear I heard a kid lol

I'm waiting for episode 3! You are phenomenal at teaching this. Thank you, i knew nothing beford this. I didn't even know the enginr was what powered to turn thd wheels. I was completely clueless to how things worked.

This is an awesome group of videos, keep em’ coming. I’m an advanced tec but love hearing the info.

Really great teaching, way of explaining things, literally and theoretically etc. Great work, thank you.

Thank you for taking the time to explain the concept SLOOOWLY thus allowing for good intake and processing of information and reducing the brain combustion caused by excess information. I too have a dog named Buddy. Also, I am thinking about switching careers. In my younger years I used to be interested in how the human mind and body function. As I got older I became interested in how things work and began to evolve in a completely different direction. I began searching youtube for diesel engine concepts and found myself enjoying your videos. You do a great job at explaining complex topics in a way that is easy to understand. Ever thought of becoming a diesel mechanic instructor?

Thank you for this series! I am currently taking online diesel tech classes and your videos help tie things together very nicely. Keep up the great work!

Here in 2022!! Great material Adept Ape

Great video I’m about to start tech school In April!

One cat dealership mechanic to another, your videos are awesome!

Well done again. Ive been at this since 1969 and this is a very well done refresher.

You make it very easy to understand. Cant wait for the next video

This is awesome you could start a premium fee based channel like Paul Danner aka Scanner Danner and make serious bank. I think a lot of people including yours truly would sign up for something like that.

This is great stuff! I actually understand quite a bit now. I didn't know what a cam shaft did before and how the cylinder head/valves functioned etc.

PRODIGY Adept Ape Tutorial 👌 👏 thank you very much helpful video Take care and have a great day KNOWLEDGEABLE Adept Ape From Nick Ayivor from London England UK 🇬🇧

Great video Josh. I like how you kept straight face when kids were going nuts on back ground 🤗🤗🤗🤗🤗🤗

Josh u r a genius another very well prepared class love it can't wait for the next one 🤓👀

I would say this is pre 101 diesel engines. It gets a little more difficult when fuel injection systems are explained. I haven't worked in the industry for more than ten years and at that time there were four basic systems: unit injectors (Detroit and some Caterpillar), pressure timed (Cummins), injection pumps inline and rotary for many kinds of engines, and of course HEUI ( hydraulics electronic unit injectors) which were found in Caterpillar, international, and Ford power-stroke. All of them use some sort of fuel system to inject high pressure atomized fuel into the cylinder using a cam of sorts but HEUI's do not use a cam for high pressure injection but instead use high pressure hydraulic oil for injection. Today diesel engines are quieter using some sort flame timing to eliminate that diesel knock. And of course soot has been a major topic of concern and technologies to lower soot levels.

Diesel engine for my building’s fire supression system started smoking heavily during a test run. Upon inspection my coworker turned on the engine while i had the air intake filter off and a microfiber rag close by. The engine sucked it up. Got it stopped quick but i cant see any of the rag in the intake manifold. im watching your videos to give me a clue what im doing tomorrow during the great rag search teardown. Any advice would be awesome. I know literally nothing about engines but i am handy.

This series may seem simple some diesel owners but as the proud owner of a 280K mile CAT C7 i need all the info I can get. I honestly open the hood with wtf? on my face every time....not any.more. I can actually explain how a Huey PUMP works, problems with them, turbochargers and more from this one channel. No offense to some youtube video guys on trucks but yall need to learn to enunciate and edit like Adept Ape does!

I have always wondered. WHY a. Diesel. Has. No vacuum with gas engine only have different fuel and Compression

Love the illustrations. Makes it a lot easier to understand and follow along. Thanks for another great video👍🏼

Hey guys very very new to mechanics but have fundamental ideas, will this series be relevant to ALL fors of desiel engines pick ups /trucks cars plant power...

I have just finished my diesel mechanic apprenticeship recently and am diagnosing trucks on my own now. Of course my mentor is still in the shop around me if I ever have any questions. But I just want to thank you so much for these videos because they have helped me get a better understanding of these engines so that I dont have to annoy my mentor with a billion questions all the time (even though he loves talking about stuff). Thank you Sir and I look forward to any videos you have coming out in the future =]

I have to learn how diesel engines work for a Coxswain course Im doing. After watching your videos Im confident of breaking through the assesment. Thanks a lot.

Good Job! Thanks, and looking forward to the next one.

Good video with one exception... the reason a gas engine's head is not flat has nothing to do with compression ratios. A gas engine's piston is usually flat or domed outward while a diesel engine piston is usually carved out with a cone shape in it. It has more to do with how the spark travels from the spark plug through the mixture and how it buns than compression. It's the whole reason behind the Hemi engine. You could change the compression ration much cheaper and easier by changing the connecting rod length to alter the amount of space between the piston and head at TDC..

Hooked like a head with a pipe and no smoke....where's part three and part four the oiling / cooling systems? Thanks for part one and two. !!

I’m a motorcycle mechanic, good video easy to understand your reasoning and yeah I saw that scored bore right away : ) Thanks

My dover of my brother the drectres of manarckcaterpilar pilipinas she is meryjeng o Ignacio liban.

Ive seen a 3508 Cat reman engine drop a valve in 39 hours . You know the rest of the story what happened to the turbos, It kept running as this series have individual heads

I have question ,far as getting the head off after bolts are out. I have a continental engine in a case crawler100D head stuck.

Very good continue to educate the public priceless job BLESSINGS

Now if someone can create a video like this about Women 101. Great video. Even a noob like me gets it.

I work on a lot of gasoline cars and engines diesels are very similar except the fuel system and compression ratio and size of the parts and some other things two as far as engine brakes Hydraulics Etc.

Thanks again for taking the time to do these videos. Lots of great detail in components and operation. I saw this uploaded late at night , it seems like a lot of work on top of your day job. You are generous with your time educating people.

I so appreciate these classes! I just purchased a 19' L5P and love it. Thanks so much for taking time out of.your day to do this for us.

at the start I thought this video is not worth watching, at last it is really worth watching. Much knowledge in this video

We need more of these videos QUICK i start college august 18th im nervous

I e been in the business for 25 years. I have to learn the ins and out of an engine. I want to overhaul one myself becuase i have 3 .

Love your videos. Too bad I don't have anything to practice on

Hi, I love your video thank you for the information

Where did you get that hat Ape? I been looking all over for it an can't find it anywhere!

Whats the mhost valuable thing to you as a youtuber. Is it subscriptions or likes...

U need more visuals to help people who don’t know what you are talking about.

Thumbs up because he didnt do his tics in this video, unlike in last part of class 1.

Thanks for your videos and for sharing your knowledge to the world

I've been lurking on your channel for the past 2 years. You've taught me alot about my C-15 Accert. I'd completly understand if you don't feel like giving advice about mechanical issues, but I have a question about coolant pushing out of my overflow tank. I'd be more than willing to pay for your opinion.

Dose anyone know how to adjust fuel pressure on a 3160 v8 cat

Great videos . Electrician here working on power generation 👍🏻

Hey I really enjoyed your videos I actually have learned a lot about Diesel engines

The timing on this discovered course is perfect for my use, thx man

Can you rebuilt my engine C15

Thanks for such a helpful well thought out explanation.

Very well explained...

looking forward for Class 3.

Do I need to have Physics in Highschool to be a diesel mechanic??

Really looking forward to the super advanced stuff, LOTS of good knowledge rattling around in your head!

Have you ever thought of looking in to opposed piston diesels?

Very happy with my free course watching you from Mexico :)

The hose bib is a valve too. The internal of that hose bib is very similar

The Valve seat was turned upside down in the demonstration.

you do great vidoes especially for the beginner

Why does the valve need to rotate? Does it reduce wear in some way?

Anyone know good reliable place to rebuild cat engine?

Yo adept ape, can you do a video on all sensors in a Diesel engine?

I thought I blew a tire when you picked up that piston

That's got to be ridiculous to put a head gasket on 🤣

man you are like profesor :) Love how you explain....

Just wanted to say thanks for these videos!

Inteaks manifold exsos manifold inteaks manefold

Class is in session #2

@Adept Ape Can I put this video series on my resume? ;-) Hehe! Thanks for the great training!

Are you fixing a salami sandwich ?

Thank you sir. Very professional.

I've been seeing these things around the shop I work at that look like these valves, but they're about the size of a golf tee. What are they?
