Jaob Neal provides an interesting and detailed picture based explanation on how car engine works and thought I must share it too. http://jacoboneal.com/car-engine/

It also covers Gas and Electric cars with animated images.

Thanks very much. Though I was aware of some of the stuff, the moving diagrams have given me better insights into how the engine and other items in the engine bay work.

Good you got that thought of sharing and Thanks for the share. clap::thumbs up

It gives a nice insight to the internal stuff. Almost like the website - How Stuff works.

There are a few things in this animation that I was not very aware of. Camshaft being one of that.

Looking for similar for gearbox, differential and steering system.

Thanks a lot for posting this link.

Found this video on - How does the Differential Works Check it out.

Wow! Nice share. After going through the webpage, I was able to clear quite a few doubts I had. Thanks. Do post more if you com across.

Amazing article it is. Only now, I've learned how engine works very clearly.. The graphical representation really conveyed a lot. Thanks a lot for sharing such a valuable link.

Good article. Is there any similar article or diagram which explains the VVT or Variable Valve Timing technology for the latest engines?

Good one. :thumbs upThe use of graphics is very effective. I had come across similar moving graphical explanation on the auto section of HowStuffWorks (http://auto.howstuffworks.com/) ; but the one provided by you is more detailed and incorporates the steps better.

By the way, where did you find this one and also does the guy explain the functioning of other auto components as well some where (off course in the same manner he has explained the engine)?

This is how Honda's VTEC works.

(EricTheCarGuy has some great videos. A good channel to follow).

Here's Toyota's VVTi

Many thanks Benny for sharing the link.
It was really interesting for a non-technical person like me.

Tons of videos around engines and getting to know them but this was unique , like the manner in which he has made use of GIF's to address the topic.

Sorry for bumping an old thread. I could not find a more relevant thread to post the below query:
Why is the inner diameter of connecting rod at big end significantly larger than the diameter of crankshaft section (crankpin) in contact? Would it not make sense to have this inner diameter only slightly larger?
Request to mods to merge this post to a relevant thread if needed.

^^^
Strength of crank.
Nature of bearing areas and loads these carry is different. The gudgeon pin rocks, the crankpin rotates.

Sutripta

Also, less space is available at the small end, which goes inside the Piston from the bottom.

Side of the connecting rod must not hit the Piston sidewalls or the cylinder wall when the connecting rod oscillates during the motion.
