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

[@Cocora22]

100%, I watch him all the time and learned how to do a lot of the basic service on my GX. It's silly that I know more about my vehicle than some mechanics where I live. That's another reason why I have really pushed myself to learn. Save money AND save my car.

[@jsun3117]

He's also corresponds with Car Wizard in the Wichita, Kansas area from time to time. Scotty Kilmer is sorta the loner YT mechanic that doesn't nor ever really associates with the others. Another master tech on this level is Eric the Car Guy who specializes in Honda/Acura.

[@sweetwatersrundeep]

I own a 90’s Honda so anything this man and Eric the Car Guy say is gold! AMD is a natural-born teacher and his dedication, obsession and perfectionism shows in the quality of his videos.

[@survivordan2187]

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!!!

[@chrisclemons7564]

I love this comment. It’s nice to see the many many little things (micron tolerances) that go into one big thing (an engine that will last forever).

[@roypeterson8537]

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

Fantastic video, I’m 50 years old and that’s the first time I’ve got to understand the different elements and processes. Excellent video.

bravo, bravo bravo!!! if something like this was available when I was 10 years old it would be absolutely life-changing. I learned about engines looking over my father‘s shoulder saying what’s this, what’s that, what do those do? Of course he couldn’t take the engine apart just to show me, but he did his best. but this is so much better. it makes it easy to love engines, with all their complexity and beauty. turns out, I became a mechanical engineer and can easily see the value in what you’re doing. thanks for being so generous with your time!

Right on! My dad is very knowledgeable about fixing cars and understanding how they work. However, he isn't a very good teacher and it was hard for him to explain to me how an engine works, especially without any visual references.

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!

Its nice to hear a person who appreciates what goes into an engine design. Every part has a calculation to it. People who criticise engines that fail prematurely, often due to small design error, have typically never designed or built anything. You should do a comparison between say a toyota engine and a cheaper not so good engine that has fewer bearing journals to save cost etc. Then people will begin to appreciate what their money is actually buying.

An engine is essentially an air pump. Add fuel and it produces power by virtue of combustion. The efficiency of the pump…sucking in the air and exhausting the burned fuel determines how it converts the fuel into useful energy. Pretty simple concept…but a lot goes into making it happen. Good video.

This was the best tutorial of how a gasoline engine works that I've ever seen, heard, or even read. I really liked how easily he explained why premium fuel is so important on certain engines and totally unnecessary on those that don't require it.

Premium fuel is unnecessary and a waste of money, but middle grade strikes the ideal balance between premium and regular.
