How Do Car Engines Work? A Close Look at The Intricate Details of an Engine

A Master Automobile Technician and Engine Specialist explains how car engines work behind the scenes.

We essentially take an engine apart to explain everything from the basic operation to how things are done inside the engine. This video is full with diagnosis tips and general knowledge that I hope would benefit gasoline engine owners in their day to day operation of a gasoline engine.

I have no problem with in dept videos like this. You uploading long videos like this just shows how much you care to give subscribers content and quality content at that.

As a young woman who lost her father 10 years ago, I’ve learned more about cars from AMD in 6 months than the mechanic I’ve been going to for 10 years. May God Bless you and give you the time in your busy schedule to teach us (especially, us ladies) how to avoid scams and how to ACTUALLY maintain our vehicles.

People fail to appreciate what a brilliant invention this was.

I’ve worked in a Toyota engine factory for over 25 years and I currently work with folks who have No idea how an engine works. It frustrates me (inwardly mostly) when we detect an issue during assembly and these folks have no idea why the issue makes the engine no good. This should be required viewing for everyone in our factory. The cylinder head is the most meticulous part of the engine in my view. The valves have 3 angles that must be a perfect width. The valve seat has a spec. of 1.2mm to 1.4 mm in the middle angle sealing surface. If they are not in that spec. the exhaust valve will “burn.” That used to be very difficult to keep in spec. during machining. The pressed in valve stem tube must have a certain roughness spec. to”hold” some oil between the stem and the tube or the engine will burn oil. The valve stem seal has to allow some oil to pass to the stem to lubricate the stem in the tube. That is a very delicate balancing act. The cross-hatch on the engines I build are allowed to be “hatched” from a 28 to 30 degree angle so oil will stay on the cylinder wall. Most folks have no idea how much testing and checking of the geometry of an engine. The journal on the crankshaft has a roundness spec of 3 microns! A micron equals 1/1000 of a millimeter. This is why Toyota engines last so long. Good video AMD!!!

My 17 year old son has been asking for a couple of years how an engine works.... well, you made his day. Videos like this are one of the many reasons why I watch and support you!!! Please never stop!!!

[davidhertzberg]

This video makes crystal clear why regular oil changes are critical to the life of an engine. And the crankshaft -- machined from a single piece of steel -- miraculous.

Never felt the urge to comment on YouTube ever until I saw this video. Amazing content. Thank you!!

You bring back SO MANY MEMORIES of my high school auto shop in the late 60's. I STILL am interested. 👍

My dad was a mechanic for 50 years before he passed 2 years ago. His advice: "Look after your car with maintenance, and it will look after you with trouble free miles". I've never had a breakdown ever (Other than a couple of flat tires) and I've driven over 1.5M miles for my job on the road. Timely fluid changes before the manufacturer tells you change them, regular inspections looking for worn out parts before the winter including the electrical system and battery health. That's all it takes! No magic. Just a little bit of TLC and a few dollars. I keep all my vehicles at least 20 years and retire them around 300-400K miles. Original transmissions and engines. I've saved a boatload not being on the perpetual car payment machine. You can too!

[SergeantTopBins]

Just watched the whole video without taking my eyes off the screen (or maybe not even blinking too). Fascinating stuff

[perniciouspete]

After viewing this posting, anyone who doesn't have an appreciation for how important regular and frequent oil changes are to the operation and longevity of an internal combustion engine must be even dumber than I am. TCCN did a great job of explaining it.

[Rieneger]

I’ve been researching tons on cars lately and this answered my longest standing one yet. I knew the fundamentals but seeing an engine literally broken down part by part helped immensely. Now I just need to learn how to perform specific tasks to work on an engine

[bernardbuhrs]

an hour long video on an engine and its please and thank you!!!

[fidelt]

I highly recommend making a series of these videos, they're very educational

[roypeterson]

Excellent video. My 14 year old grandson is getting car fever and been asking me many questions about cars and engines. My education after high school was aircraft maintenance at the Institute of Aviation which was at the university of Illinois in Champaign-Urbana. My training was on aircraft radial engines where we learned overhaul, troubleshooting, etc. The last 30 plus years of my career was on commercial jets and turbine engines. I’m 75 and still working on cars and now passing on my knowledge to my grandson. He wants to do a project car which may be a bit more than I can handle. Got the tee shirt of that experience with my son on a Mazda RX-7. So texted my grandson this video link as you explained the theory so well. I really enjoy your videos and knowledge. I just bought a 2024 Toyota Prius Prime. Watched your video and it reinforced my decision to pursue the purchase. Cheers

AMD, Congratulations, this is the first video from the new 'TCCN Studio'. 🥳🥳🥳🥳 When will you install seating for the live studio audience? 🤔 Please keep the concession and parking prices reasonable for the fans. 😉😂🤣

[harrychoke]

I'm afraid I disagree with those that say this is a masterpiece. This goes beyond masterful - it is perfect. It is the best I have seen. Thank you for this, very much appreciated for your time and knowledge.

[VividLasting]

wow, finally so many years someone can help me with understanding what is going on with the engine.

[YotaLife]

What a treat for a Saturday afternoon to enjoy a cold one while watching CCN! Thank you!

I recently discovered and subscribed to your channel, and simultaneously wanted to find videos explaining how car engines work... The timing of this video, and the teacher giving the lesson couldn't be more perfect
