Loved this series. As a visual learner working on my ASEL commercial, this really helped me understand how the guts of the engine work. Would love to see something like this for other key systems like fuel, electrical, and retractable gear in the future!
Thank you so much! I really appreciate your generosity and plan on using it to support more content. Including an upcoming magneto and electrical system episode!
Wow having the visual walk through adds another frame of reference… this really helped me understand pistons sooo much better! Thank you Seth!! Your passion is contagious!🙏🏻🙏🏻
This series was fantastic, great idea to help us visually understand the engine and thereby what the gauges are telling us is happening or not happening correctly! love all your videos keep up the great instruction and education for us all, you are making us all better and safer pilots!
I think we all need our instructors to give us a visual walkthrough of the engine parts like you just did. It’s not the same as reading about it. I was able to follow your explanation of each of the components because of the reading I’ve done but this was the last piece of the puzzle. NOW I get why loss of oil pressure is a really bad thing.
@@SethLakeDPE Hi Seth - as I said, excellent presentation across all 4 videos. You have provided - free of charge - a phenomenally detailed overview of the combustion engine. Thank you (I had to make my previous comment brief, as I was finishing the video right before we - family - needed to leave for a soccer tournament). One question I have, regards the rings - They are made of spring steel. Why doesn’t the heat and friction fail the rings with regularity? I get that the oil is not only lubricant, but also a cooling liquid, but the scraping of the oil from the cylinder walls reduces the amount of heat displaced … doesn’t it? Is this purely a combination of the structure/mixture of the spring steel coupled with the overwhelming transfer of heat to the oil? Or something else? I attempted to ‘Google’ it, and got nothing other that ‘race performance’ inferences…
I've been following you since the Instrument Rating ACS review and I think that really helped me getting ready for the check and I passed it. And recently I'm rewatching your Commercial ACS review for my upcoming check, I found this series which is really cool seeing the actual counterweight and all the components. It is really helpful for building my knowledge and understanding the principle of how it works. Huge thanks for the great content!
Loved this series! Currently working on my CSEL rating and have struggled with systems, engine, etc. up to this point. These videos have been super helpful and will definitely be sharing with all pilots, and aspiring pilots I know. Thank you for putting this out there and please make more content like it!
Great series. Clear and concrete, easy to follow, understand, and internalize. Really useful in these 'modern' times where it's uncommon to have the chance to see and handle anything mechanical firsthand. Thank you for the great presentations!
Guessing when you pointed into the middle of the prop that was a sludgy mixture of motor oil and grease and it’s still removed for overhaul or replacement. Normally the grease is contained within the hub gearing but over time the seals fail and mixing takes place. Alas the reason for tach and calendar time on recommended prop TBO. You don’t want part of a prop departing the aircraft and taking a wing out.
That was all just old engine oil. It does get pretty dirty but none of that was actual grease. The propeller grease is red so you can identify it if/when it leaks. The Travel Air propellers are a little unique in that they get pulled every 500hrs for an AD inspection. I'm always surprised at how bad the oil looks after just 500hrs. None AD props might stay on for 2000hrs!
Talking about the flywheel made me crack up about how we use that term with aviation engines. Don't get me wrong, I couldn't think of a better word, but I can't help but wonder if that thing provides any significant momentum to the engine while it runs. The propeller weighs so much more it's not even funny! Would the flywheel even help if you ran the engine propless? Maybe we should call it the starter gear engagement disc, haha!
Great question! I think my next systems video will be on magnetos actually. The reason we have a magneto is so our spark plugs are using a independent and redundant system to operate. In the early days of aviation (when a lot of these systems were first designed) airplanes didn’t have electrical systems at all. Magnetos were used in many other combustion engine operations and were very reliable. You could design (and people have) a electric ignition system that was tied to the electrical system, but that would remove some of the redundancy offered by this set up. Thanks for watching!

Great job, very well done! Thank you
You're welcome!

Thank you so much for the feedback! So glad to hear your finding some of my content useful.
Excellent explanation of the engine. Appreciate the complete breakdown of the engine and being able to see the internals. Thanks!
You're welcome!
You have the LUCKIEST students to have an instructor like you. Thank you soo much for sharing. Love love your content
You're very welcome!

I agree that it's a totally different experience going through the actual parts in person verses just reading about them.
Well done presentation across all four videos. Excellent format and clear and concise explanation. Should be required viewing for PPL students!
Thank you for the feedback!

I share all of your content with everyone I know 😀. For my students, it is required viewing! Great stuff Seth!
Thank you so much!
Love it!
electrical systems next!!
Along with failures associated, I still struggle understanding all this
YES! Magnetos and electrical system videos will be up next.
@@SethLakeDPE Looking forward to this!!

Thank you so much for the kind feedback. Good to hear you found the content useful!
@@SethLakeDPE I'm thinking / hoping your channel will become a 'gotta view' for GA pilots (and arm chair aviators). Best wishes!
Brilliant videos all the time from you!
Thanks!
Great video! Thx for sharing.
Great video and series, Seth. Keep up the great work. Safe skies 🇺🇸🛩️
Thank you!
Wonderful series. So very relevant to my ignorance on the subject. Thank you
You’re welcome!
Great content as always!
Thanks!
This was amazing. Electrical system maybe and how to read electrical schematics series Wdyt?
In the works now!
Dope content bro 🫡🫶🏽 love your channel man I just subscribed
Great!

When I got my Skylane the prop only had 500 on it but 36 years smoh, mostly sitting. It was definitely time!

Yeah, it's interesting we still call them that. That honestly might not be the correct term but it's still what I use.
OK, newbie here, maybe dumb question. If there is an alternator and/or generator, why a magneto?
