Anyone else feeling like this is a bad explanation? - Start by talking about what "everyone knows" to someone watching a basics video. Ugh. - describe something as "'obviously' extremely complex" to an audience who don't know the basics. - in the next breath, describe it as a 'pretty simple' principle. Ugh. - ignore simple principles and talk about air pumps with exhaust as a side effect. - the purpose is to rotate a shaft. [audience who doesn't know the basics knows what a prop shaft is, despite it not being pictured or explained]. - which in turn rotates the wheels [also not pictured]. - it does this by connecting that shaft to pistons that move due to a mixture of air and gasoline combusting inside their cylinders which creates a sort of chain reaction. - let's talk about the block and head I think some basic introduction is missing - drawing attention to the fuel having stored energy that we want to use to move a car, that burning a drop of fuel makes a small explosion. Explosions push outwards in all directions and if that push can be captured and used to turn a car's wheels, it can move the car. That's where the engine comes in at all. Place for the explosion, comparison to canon/space rocket/firework/gun/steam train turning it into linear movement, crankshaft turning it into rotary movement, comparison of spinning a playground ride or a bike wheel by hand, giving it occasional pushes, and that moves the piston back and squishes the exhaust gas out, and how it would be a lumpy ride with big jolting pushes and then coasting for a bit, so ... Look at the YouTube comments: - "where does the pistons get the power initially to the moving down and ignition? I see it does it with the lingering power from the exhaust pipe after the first stroke cycle but where does the power come initially?" - "Good questions, hopefully someone smarter than me finds this comment cause I’d like to know too" A five minute basics video that says "cars get power from their engines" and purports to show you "how an engine works" but doesn't explain where the power comes from, leaving the audience confused about how the engine works. More confused comments: - "It's a good video [...] I looked at it once and figured out what it means in the engine. Where the pistons are located and that they are powered by the crankshaft." - "I feel so slow. I'm watching this and I'm already getting lost lol. Cars are too complicated for me, I guess." - ""First the piston moves down"...HOW??? LOL...that is OBVIOUSLY not "First", because what caused that?" Finish by saying "there's obviously a whole lot more to say about engine tech" another 'obviously'. Don't give any examples.
