SOHC vs DOHC | Autotechlabs

If you are an automotive enthusiast, then you might have heard the terms SOHC and DOHC at some point. This presentation demonstrates the difference between both these engine head configurations and their working principles. Hoping you could learn something from our presentation, please like and subscribe!

My god, what a quality of presentation:
-simple:
-interpretative;
-informative;
Great job, with presentations like this, going to school is more drying than normal.

Keep going please, we need to learn things

A simple explanation can only be done by someone who understands deeply the subject. Amazing videos

Great graphics. One significant advantage of SOHC motors is that it is usually much easier and less time consuming to check and set valve clearances. DOHC motors require shims to set valve clearances and much more time is required to get at them. However, valve clearances in DOHC motors stay set for a longer time than in SOHC motors.

Beautifully done. I'm so happy to be learning how engines work. I've been wanting to know for a long time. This makes it all so clear!

Thanks for the information, i'm currently educating myself as a mechanic even tho i have multiple books and websites i really find all of your videos great for applying the information with cool and accurate animation of the internal and external workings of the things you teach :) keep going man this is great learning material both for those hobbyists, students and educated mechanics who need to be refreshed in their info :)

This is the reason why I love this Channel . All the video are well explained and good presentation that make us understand easily. Thank for providing a valuable video and please keep doing this.

Very good, great animation.
A couple of things, a number of SOHC engines were 4 valve per cylinder, examples being the Honda J series, Chrysler EGJ and offspring, Nissan KA24E and several more. A number of DOHC engines do use rockers, so there are exceptions to the rules, but as a general explanation this video is great.

test drove a 2014 chevy 2500 (sohc), 2007 tundra 4.7 v8 (dohc), ram 2500 (ohv, single ohc), 2009 frontier v6 (dohc). Now i live where there is atleast 4 miles of steep uphill its a huge test to show what your vehicle is made of. You can see and feel the difference of a dohc made vehicle, managed to keep a steady 75 mph from leveled road all throughout the end of the top uphill with one engine shift at 2-3.5 rpms (for the dohc trucks). The single cam ohvs blow these trucks out of the water in terms of power but my mph went from 75 mph (leveled road) scaled down to barely 60, 2 quarters near half way the uphill at the same 2-3 rpms. Real world performance to suit your needs. Listen, well made is better than the numbers in the stat sheet. Get a dohc vehicle especially if you travel to work in mountainous areas, long uphills. From what I've seen new or old the v4 cars end up blowing their transmissions its just a nasty uphill go v6 if u cant afford a v8. Obviously get the 2500 trucks if your towing or dumping heavy material.

Keep going. You have great diagrams and the new voice is great

I have been looking for this exact video for months without knowing that it existed. I can not thank you enough for this. Thank you.

[hosamgalal]

What a marvelous presentation, I've never seen a simplicity like that.

[cosmicoven]

Scotty kilmer next video "Why not to buy SOHC and DOHC" lol just kidding.

[nurialco]

There's no question marks after the video at all. Even its not explained with my main language i have no problem to understand. Great job.

[kasunsiriwardena]

Keep on doing such beautiful videos & don’t worry about people complaining about the computerised voices, we can learn a lot & understand so well how seperate system works... Please do a video when you start the car (insert the key & switch on the engine how it works) to have a complete clear picture, then teach us how each system works like you’ll did the video for breaking & cooling system

[mrkatse]

I love how Youtube recommends things I don't need to know but need to know! Thank you Youtube Thank you @autotechlabs

[Documenting_Reality]

You only made 7 videos in the past 5 years damn u should upload more often I enjoy ur explanations 🤠

[bedirhanakdag]

Great animations, great explanation. Thanks for the video. And please don't be gone for another 2 years.
